How Radiotherapy Can Help In Treating Blood Cancer

Blood cancer is one of the most common categories of cancer, accounting for up to ten per cent of cancer diagnoses. Among the most familiar forms are leukaemia, lymphoma and myeloma.

These can come in different sub-categories:

Leukaemia types include acute myeloid leukaemia. This impacts the myeloid cells and causes a loss of white blood cell production, which undermines the immune system.

Lymphomas include Hodgkin and Non-Hodgkin types, the latter being significantly more aggressive.

Because these are prominent kinds of cancer, much research and development work has taken place into discovering, enhancing and refining treatments for them, which includes radiotherapy treatment. This means many medical resources can be deployed to tackle blood cancer.

Advances In Blood Cancer Treatment

The progress that has been made in producing better outcomes is highlighted in the UK each September, which is Blood Cancer Awareness Month. Organised by the charity Blood Cancer UK, it aims to raise awareness of these conditions, arguing that they receive less attention and research funding than other forms of cancer.

However, it also has a good news story to tell, with studies showing that myeloma survival rates have approximately doubled in recent years. Such improvements do not just help patients in Britain, but all around the world.

Blood cancer treatments are now more numerous and effective than they used to be and include some therapies that did not even exist a few years ago.

Part of the reason there is a wide array of treatments is that the different cancers will each have their own elements that can be impacted more effectively by specific treatments. Chemotherapy is widely used and immunotherapy drugs are increasingly deployed.

Radiotherapy For Blood Cancer

Even so, radiotherapy still has a significant role to play. Indeed, this has also become more advanced to the benefit of patients. It can be targeted more precisely than ever when this approach (known as stereotactic radiotherapy) is required.

Lymphoma and multiple myeloma cancers are among those that are commonly targeted using radiotherapy. This is because they originate in blood-forming tissues, either in bone marrow or immune cells.

Radiotherapy can have multiple beneficial effects. Firstly, similar to how it works with other conditions, it destroys cancer cells in the bloodstream.

Secondly, it can have a therapeutic benefit by easing some of the symptoms of the cancer. This includes reducing the pain of swelling from an enlarged liver, spleen or lymph nodes and reducing the bone marrow pain caused by the damage done to it by cancerous cells.

When Stereotactic Radiotherapy May Be Used

Stereotactic radiotherapy, which uses very precise beams of radiation to deliver high doses of radiation to specific areas while minimising exposure for sensitive adjacent organs and tissue, can be extremely effective and invaluable in treating many cancers that exist close to vital organs. Stereotactic radiotherapy is selectively used for blood cancer.

Examples of this include blood cancer affecting the chest and abdomen, or in the neck and head in the case of Hodgkin Lymphoma.

Our cancer treatment services include the capacity to deliver stereotactic radiotherapy using some of the most advanced equipment, aided by the most accurate scanning technology available.

Whole Body Radiotherapy

However, radiation therapy can also be given in other ways. In some cases, whole body radiotherapy is given. This is commonly used for leukaemia patients before stem cell transplants. Lymphoma and myeloma patients may also receive this treatment.

Here, you would lie prone on a table while the radiation is delivered by a Linac machine. This can move around the patient and be used to direct radiation wherever it is required.

In cases of location-specific cancer, meanwhile, radiation will be targeted at certain areas.

The Side Effects Of Radiotherapy For Blood Cancer

As with radiotherapy for any form of cancer, there will likely be some side effects. These can include fatigue, hair loss, a reduction in appetite, diminished libido, skin changes (including dryness and soreness) and, on occasion, diarrhoea and stomach upsets. If you are undergoing chemotherapy as well, this will also produce some side effects.

However, it is important to remember that the side effects of radiotherapy, while unpleasant, are not permanent in most instances. For example, after treatment ends, you will find your appetite returns and if you have lost your hair, it will start to grow back.

If you have any of the common blood cancers, or even a rarer type, you may feel unhappy with the treatment given so far. Using the best technology and the most advanced treatments and techniques, our private radiotherapy centres may offer a better approach.

We specialise in radiotherapy, but offer chemotherapy as well, which may be particularly effective for your condition when the two approaches are used in combination.

How Using AI May Increase The Precision Of Radiotherapy

The purpose of a modern radiotherapy centre like ours is somewhat different from those established long ago, when the technology involved and the medical understanding of it were in their infancy.

Radiotherapy has been used therapeutically since the turn of the 20th century. But in the early years, it was only able to have a palliative effect on patients with a terminal cancer diagnosis. Although it can still be used this way, extending life in the process, it now offers many more possibilities, including the promise of a full recovery for many.

Advances in treatment have been partly aided by increasing understanding of radiation and its effects on the human body, as well as the capacity to deliver radiation in ever more precise ways.

The Benefits Of Stereotactic Radiotherapy

The most precise form of radiation delivery is known as stereotactic radiotherapy, which uses very concentrated beams of radiotherapy to target tumours while minimising exposure to surrounding tissue. It is commonly used in areas where precise aim is of particular importance, such as the brain, lungs or spinal cord.

That has been possible both through the development of new technology, with Gamma Knife being a prime case in point, as well as scanning technology to identify exactly where precise beams of radiation can be aimed.

Not only does this raise the prospect of treating the cancer more effectively, especially when it is a primary cancer that can be targeted in one specific location, but the lack of exposure of the surrounding tissue and reduced number of appointments required to deliver the required dosage can both minimise the side-effects and maximise the impact of the treatment.

For this reason, we have invested in the latest and most precise equipment to provide patients with radiotherapy. In the future, we will continue to do so as new innovations emerge.

Amethyst & AI In Radiotherapy Treatment

At Amethyst Healthcare Group, we already use AI in radiotherapy planning and tumour contouring.

 

Out of the three stages (planning, contouring and treatment delivery), AI currently supports the first two, while dose distribution is earlier in integration but progressing. In image analysis, AI can match or exceed human performance in spotting early signs of cancer, as we expand diagnostics, we will integrate these tools to strengthen prevention.

How AI Innovation Could Help Cancer Patients

Among the areas of great potential at present is artificial intelligence (AI). While the wider impact of AI on society and economies has been widely debated, the evidence is that it can bring some significant medical benefits.

The latest instance of this is research produced by the Shenzhen Institute of Advanced Technology, published in Digital Medicine. Experts at the institute have developed a new multi-modal deep learning model that can improve decision-making over the delivery of precision radiation.

Focusing on cervical cancer, this research set out to tackle the problem that while 70 per cent of patients can be successfully treated and cancer-free, the rest suffer metastasis (where cancer spreads into other parts of the body) and therefore face a worse prognosis and the prospect of extensive further treatment.

Machine Learning May Solve Treatment Dilemma

Although more intense treatment can reduce the risk of metastasis, this will produce more toxicity and the side effects that come with it. However, the researchers found, the AI innovation has made it possible to judge more precisely exactly where radiation should be directed, meaning less treatment is required to achieve optimal outcomes.

Known as CerviPro and using CT technology to assess patients and make judgments, it has been tested on 1,018 patients in Chinese hospitals, with very promising results. In particular, it proved very effective at distinguishing between high and low-risk patients when it came to the likelihood of metastasis.

This development is not, in itself, an innovation that can deliver stereotactic radiation with greater precision than existing devices. What it is, however, is a means of assisting in decision-making that can help achieve a better balance between maximising treatment to tackle cancer and minimising the side effects.

Why Side Effects Should Be Minimised Where Possible

Anyone who has had some radiotherapy already will be familiar with common side effects, such as fatigue, hair loss, skin problems, digestive issues, and, occasionally, reduced immunity caused by a low red blood cell count.

None of these are permanent issues, of course; for example, your hair will grow back after treatment and your appetite will return to normal. Nonetheless, the course of treatment will be easier for patients if the radiation exposure and its side effects are minimised.

Looking To The Future

The use of AI in the Shenzhen research may be just one of many innovations to come from that quarter that will help enable even more precise and well-calibrated delivery of radiotherapy. Alongside this may come yet greater precision tools for delivering beams of radiation.

Some of this will be for the future and therefore not be of benefit to patients in the present. However, we have always sought to acquire and use the most advanced equipment currently available and the best possible techniques associated with it to offer the best treatment to cancer patients.

Indeed, while AI may be the technology of tomorrow, many of the devices and methods we use today were once in that same category.

How Private Chemotherapy Can Help Ovarian Cancer Patients

Cancers come in many different forms, but one thing they all have in common is that early diagnosis can make a significant difference to outcomes and treatments.

The sooner a cancer is spotted, the less it will have progressed and a particular benefit for the patient can be when a cancer can be treated before it can go through metastasis, the process in which it starts to become secondary cancer by spreading from its original site to other parts of the body.

However, even with early detection, you may need significant treatment. This can include private chemotherapy treatment as part of the treatment process.

New Test Raises Hopes For Early Ovarian Cancer Detection

The prospects of more cases of ovarian cancer being detected early appear to have taken a giant leap forward following new research carried out in the UK and the US.

Scientists at the Universities of Manchester and Colorado have found that a new test can detect biomarkers for ovarian cancer with more accuracy than existing tests.

In Colorado, the tests showed a 93 per cent accuracy for all stage detection and 91 per cent for early-stage cancer. In Manchester, the respective figures were 92 per cent and 88 per cent.

The test was developed by diagnostics company AOA Dx. Reflecting on the results, the company’s chief science officer, Abigail McElhinny, said: “This platform offers a great opportunity to improve the early diagnosis of ovarian cancer potentially resulting in better patient outcomes and lower costs to the healthcare system.”

At present, 90 per cent of women with ovarian cancer have symptoms when the cancer is in stage 1, but only 20 per cent of cases are detected that early.

If you have been diagnosed, it may very well be that the disease has progressed beyond stage 1, which is when the cancer is confined to an ovary or fallopian tube. At stage 2a, it spreads to the uterus and, in stage 2b, can be found in other locations in the pelvic region.

Only at stage 3 does it spread to the lymph nodes, at which point the cancer can reach other parts of the body away from the pelvic region.

The Role Of Chemotherapy In Ovarian Cancer Treatment

Whatever stage you are at after diagnosis, chemotherapy may play a significant role in treatment. This is most commonly used before or after surgery to remove the ovaries.

There are different ways in which this may be administered. Chemotherapy drugs can be given in pill form or administered via a drip, depending on which drug is used and what stage the cancer is at. The drugs are toxic to the cancer cells and can target them effectively.

Understanding how chemotherapy works is important for any cancer patient, but it may be especially true for cancers like ovarian cancer, which is seldom treated with radiotherapy. This is in contrast with some cancers where radiotherapy and chemotherapy are sometimes used in combination.

How Chemotherapy Drugs Work

The main way in which the drugs work is by damaging the capacity of the cancer cells to multiply. Like other cells, they do this by dividing, and different chemotherapy medications will impede this process in various ways.

Some attack the nucleus, where the control centre that launches the process of division is housed. Other drugs might disrupt the chemical processes in division, damage the cells as they divide to stop them from making accurate copies of their DNA (which stops further replication), or damage cells at the point of division.

Because there are these four different ways in which chemotherapy can attack cancer cells, there are multiple options for tackling cancer. That might include using one particular kind of drug to target it in a specific way, or a cocktail of different drugs to launch a multi-front assault on the cells.

In the best-case scenarios, these will remove any remaining cancerous cells after surgery, enabling the patient to go into remission.

Tailoring Treatment To Individuals

Our approach to private chemotherapy treatment is to treat everyone as an individual. This means each patient’s needs are assessed to deliver precisely the right treatment. This is designed to ensure the right drug is given, in the correct dosage and that the treatment is continued for the correct length of time, with adjustments when required.

This will also involve helping you to understand factors such as the side effects of chemotherapy and how you and your loved ones can cope with them. These can include gastrointestinal upsets, nausea and vomiting, fatigue, anaemia and a weakened immune system.

It is central to our approach that you not only get the best treatment, but are kept informed all the way, with full explanations of the treatment, its effects and side-effects. In doing all this, we will provide you with the best care possible.

Study Favours Radiotherapy Over Surgery For Prostate Cancer

Prostate cancer is a major health issue for men across the world, especially those aged over 50. Although the risk varies significantly with factors such as ethnicity, family history, age and so on, it is the most commonly diagnosed cancer in men, affecting one in eight at some point in their lifetimes.

For this reason, finding the right treatment for each patient is a high priority. Not every prostate cancer is the same and some treatments (such as hormonal therapy) can work effectively for some patients, but not others. This is why personalised care is particularly important.

However, at Radiotherapy Healthcare Group, we know that radiotherapy can be an effective treatment, potentially used alongside other treatments (such as surgery, chemotherapy or hormonal therapy) that also play a part in a cancer management programme.

A key question for many patients and their oncologists often arises when the decision to be made lies between using surgery and radiotherapy. Surgery can have a lot of lasting (and often permanent) side-effects, including some loss of urinary and sexual function, which means radiotherapy can be preferable from a quality of life perspective.

New Study Supports Radiotherapy Over Surgery

New research from the United States has indicated that in the case of high-risk prostate cancer, radiotherapy is a better option than surgery. The study, by experts at the University Hospitals Seidman Cancer Center in Cleveland, Ohio, was published in European Urology Oncology.

It stated that when faced with high-risk cancer (defined as having a greater than normal chance of metastasis, which is when it spreads to other parts of the body to become secondary cancer), radiotherapy was more effective in preventing this from happening.

The key finding was that a combination of radiotherapy and androgen deprivation therapy reduced distant metastases by 32 per cent more over an eight-year period than the surgical option of radical prostatectomy.

Speaking to Medscape Medical News, one of the study’s authors, Daniel Spratt MD, said: “While it’s not a head-to-head randomized trial between surgery and radiation plus ADT, it provides compelling comparative data suggesting that radiotherapy plus ADT may not just be equivalent.”

Instead, he added, the radiotherapy treatment “might be better when it comes to controlling disease and reducing treatment escalation.”

More Research Needed

Dr Spratt acknowledged that the study “moves the needle but does not end the debate”, which means further research is required. Nonetheless, it does suggest that the best available evidence at present points to the preference of radiotherapy over surgery in high-risk prostate cancers.

Because the findings are tentative, they will require peer review and there is some scepticism about the findings.

Medscape Research News also spoke to William Kelly, head of oncology at Thomas Jefferson University Hospital in Philadelphia, who said the question of whether radiotherapy for this kind of cancer was the best option has “still not been answered”.

Nonetheless, it is studies of this kind that can mark the first step in a new understanding of what can be achieved by radiotherapy. Indeed, if more research backs up the study from Cleveland, the next stage may involve examining whether some methods of delivering radiotherapy are better calibrated than others to maximise the benefits.

Another Shift Away From Prostate Surgery?

The new study is not the only recent development with the potential to swing medical opinion in favour of alternatives to prostate cancer surgery.

Last month, British charity Prostate Cancer UK criticised what it called ‘outdated’ recommendations for slow-developing prostate cancer by government regulatory body the National Institute for Health and Care Excellence (NICE), which it said were leading to around 5,000 unnecessary surgeries every year.

It argued that NICE had failed to update guidance despite the knowledge that many slow-growing prostate cancers take so long to become a serious health risk that they won’t impact the patients in their lifetimes, in which case any side-effects from surgery, such as incontinence and impotence, may be suffered without due cause.

The charity revealed that its campaign on the issue brought a rapid response from NICE, which has expedited a review of its guidance. The last update of the guidance was made in 2021.

Personalised Care Matters

Although this particular review could lead to a greater focus on monitoring rather than surgery instead of increasing the use of radiotherapy, it does go to show that as medical science advances (both in terms of diagnostics and treatments), guidance can be amended and surgery can become less favoured.

If, therefore, you have prostate cancer and are unhappy with the treatment given so far, we may be able to offer an alternative through a fresh, evidence-based and personalised approach that makes use of the very latest treatments and understanding of your condition.

Amethyst Radiotherapy - Prostate Cancer

Why Prostate Cancer Patients Need Personalised Treatment

A key feature of our treatment programmes at Amethyst Healthcare is to offer personalised care that is tailored to the needs of each patient. In rejecting a one-size-fits-all approach, we aim to achieve better patient outcomes and to acknowledge that everyone is different.

This is something that may be particularly appreciated by those who have found that other providers have fallen short in this regard. Not only does that mean that the treatment offered may not be the best option, but it can also mean individuals are being given a treatment based not on what might be best for them, but on presuppositions about what is best.

A good example of where this can occur with highly negative results is the area of prostate cancer. The diagnosis of this disease is not in itself a prognosis of how it will develop, as tumours vary widely in how aggressive they are. This alone is a good reason to personalise treatments according to individual patient circumstances.

Prostate Cancer Treatment Concerns Raised

However, this is not what always transpires. For example, the charity Prostate Cancer UK has warned that in Britain, as many as 5,000 men a year are given excessive treatment for their condition. This can mean they unnecessarily suffer side effects like erectile dysfunction or incontinence.

The charity held the National Institute for Health and Clinical Excellence (NICE), a state-run body that issues treatment guidelines, to account for providing obsolete guidance.

Its key point is that for a quarter of patients, the tumour grows so slowly that it is not going to manifest itself harmfully in their lifetimes, making the treatment they may be given unnecessary.

Instead, such patients may benefit from close monitoring, with further treatment only required if the cancer growth accelerates.

This may also be the case for other similar guidelines in healthcare systems around the world, as well as in the UK.

Speaking to the Independent newspaper, professor of urology at the University of Cambridge Vincent Gnanapragasam said the NICE guidelines “have created a deeply concerning wild west on how surveillance is implemented by different health care teams.”

He added: “This inconsistency is resulting in a lack of confidence from patients in surveillance, who may instead opt to have treatment they may not have ever needed, risking harmful side effects.”

The Search For Personalised Prostate Care

The issues raised with NICE affect Britons using the state-run National Health Service, but many prostate cancer patients from other countries might find they have similar problems with treatments being implemented that are not ideal for their individual conditions. This may be applicable both in state and private healthcare systems across Europe.

Wherever you are located, you can do better than this. Radiotherapy should only be given when required because of its various side effects.

For cases where you do need radiotherapy, we can still offer treatment that is geared up to individual needs, as there are differing ways of using radiotherapy for prostate cancer, as well as multiple options for combining it with other treatments, such as surgery and chemotherapy.

Radiotherapy Options

Radiotherapy for prostate cancer can be external or internal. The first of these involves external beam therapy, which is commonly used when the cancer is confined to the prostate itself.

This can involve the use of stereotactic radiotherapy to direct very precise beams of strong radiation at the tumour, shrinking it while minimising radiation exposure for surrounding healthy tissue.

Internal radiation therapy, known as brachytherapy, involves placing a very small implant of radioactive material in the prostate. In some cases, this is temporary and in others permanent, depending on patient needs.

Like external beam radiotherapy, brachytherapy is used when the cancer is confined to the prostate gland. Metastatic prostate cancer, defined as when the cancer has spread to other parts of the body, may be treated by radiopharmaceutical means. This usually only occurs as a treatment for stage 4 cancer.

Taking an Individual Approach

These variations, combined with the different surgical, chemotherapy, targeted therapy and immunotherapy options (among others) go to highlight that there are many ways to treat prostate cancer and it makes little sense to make presumptions of what is best for each patient without considering their circumstances.

Among the variations are factors such as age and general health, while some people will respond better to some treatments (such as chemotherapy) than others. Hormonal therapy can help in some cases but not others.

All of these factors will play a role in the prostate cancer treatment we can offer you at Amethyst Radiotherapy. But we will also treat you as an individual person, discussing your treatment options, explaining the benefits and side effects, and helping you to feel a part of the decision-making process.

In doing so, you should get the best care available, which can improve your prospects for a better outcome.

amethyst radiotherapy - doctor man medical diagnosis of lungs

World Lung Cancer Day: How We Are Advancing Treatments

One date of note for the medical profession in general and oncology in particular is August 1st, when World Lung Cancer Day takes place each year.

This occasion helps to raise awareness of the disease, not just in terms of the risk factors for developing it, but also the symptoms that can indicate a problem and the associated importance of early detection.

Here at Amethyst Healthcare, the importance of all this is increased by our role in treating lung cancer, which is not just an area of expertise, but a focus of some of our most notable recent innovations, with our Austrian arm being especially prominent in the latter area.

Risks And Prevalence Of Lung Cancer

According to the World Health Organisation, lung cancer is the leading cause of cancer mortality among both men and women worldwide.

It is eminently preventable, as 85 per cent of cases are caused by smoking, but the key to raising survival rates is early diagnosis, as it is common for the disease only to be identified at a late stage when treatment options are more limited.

The fact that most cases are related to smoking does mean those who smoke or have done so in the past should be aware of symptoms indicating the possibility of cancer and get checked out. Equally, the fact is that a minority of cases have other causes, such as air pollution.

Experts have also noted that non-smokers usually only get one type of lung cancer, lung adenocarcinoma, which is a type of non-small cell lung cancer. Smokers, by contrast, can catch different forms of lung cancer.

Spotting The Symptoms

Raising awareness of lung cancer is not just about warning of the dangers of smoking, which are well known and have contributed to a steep decline in smoking rates across the world. It is also about spotting the symptoms so that a diagnosis can be made as early as possible, maximising the possibility of successful treatment.

Among the common early symptoms are chest pain, a chronic cough, and breathing issues. Unplanned weight loss may also occur. More advanced symptoms will include wheezing and coughing up blood. Anyone suffering such symptoms should see their doctor as soon as possible.

How We Treat Lung Cancer

When it comes to treating lung cancer, radiotherapy is a powerful and commonly used method of treatment. There are different ways of administering radiotherapy and our approach involves using personalised and tailored treatments for each patient, rejecting a one-size-fits-all approach with individualised care to seek the best possible outcome.

In the case of lung cancer, we use non-invasive treatment, which involves the delivery of radiation by means of intense beams, usually with the patient lying in a linear accelerator.

The modern equipment we use ensures that the maximum amount of radiation is delivered to the cancerous area to destroy cancer cells, while minimising exposure for surrounding tissue.

A New Innovation In Austria

While our treatments are very modern and powerful, we are always seeking methods of delivering even more effective and personalised treatments, bringing the latest research and innovations to bear. When it comes to lung cancer, Amethyst Austria is leading the way with the newly introduced TTFields therapy by Novocure.

This CE-marked treatment, which is aimed at tackling metastatic non-small cell lung cancer, uses electric fields to target cancer cells. This is based on the simple fact that electric fields have different effects on the human body depending on the frequency. This has already enabled the development of various medical devices and innovations, such as pacemakers.

In this instance, the treatment takes advantage of the fact that cancer cells have polar cellular components, which means they can be affected by electrical fields at certain frequencies, between 100 and 500 kHz.

At this range, the electrical waves can breach membrane walls in cancer cells and disrupt the operations of those cells, killing them in the process. The good news is that it can do this without harming healthy tissue, leading to effective treatment without causing significant harm to the surrounding area.

In the case of metastatic lung cancer, this means attacking cancer cells in the lungs and elsewhere, including other important organs, without causing a lot of damage to the organs themselves.

This innovation is a demonstration of the kind of cutting-edge technology and medical science we are bringing to bear at our different cancer centres. Each step forward enables us to offer more powerful treatments, widens the range of treatment options and therefore enables us to provide a more tailored approach to the needs of every patient.

Study Supports New Brain Tumour Radiotherapy Approach

Stereotactic radiotherapy is one of the most advanced forms of radiotherapy. It is designed to achieve the delivery of very concentrated and precise beams of radiation to tumours while minimising the irradiation of any surrounding tissue, which makes it invaluable when tackling tumours and cancerous cells in or adjacent to the brain.

If you are seeking private radiotherapy, your primary aim should be to get the best possible treatment, perhaps something not available via your country’s state health system, using the most advanced and appropriate form of radiotherapy.

What Is Stereotactic Radiotherapy?

Not every form of cancer needs stereotactic radiotherapy, but brain metastases certainly do. Metastatic cancer is a form of cancer in which the disease has spread from its original site to other parts of the body. That could mean brain cancer spreading to other parts of the brain or elsewhere in the body, or another kind of cancer spreading to the brain.

In either case, this is among the most serious forms of cancer anyone can suffer from and significant intervention will be required. The two principal means of treating brain cancer are through surgery to remove part or all of a tumour and stereotactic radiotherapy to shrink it.

Surgery vs. Radiosurgery: A New Approach & Key Findings 

These are commonly used in combination in the course of treatment, which means studies to find ways of delivering this combination in ever more effective ways are a very active area of research around the globe.

In a particularly notable development revealed this month, research in the US has indicated that a new method of combining stereotactic radiosurgery (SRT) with surgery is not only safe, but displays enhanced outcomes compared to the alternative approach.

The randomised clinical trial by the Eastern Cooperative Oncology Group, published in the Journal of American Medical Association, set out to establish the safety and effectiveness of using SRT on patients before operations to remove resectable brain metastases (cancerous cells that can be removed surgically), with the purpose being to compare outcomes with the alternative of carrying out SRT after surgery.

What the study concluded was that the pre-operative SRT was just as safe for patients as post-operative treatment. In addition, the pre-operative treatment produced two positive benefits, with more treatments being completed and the time taken to finish treatment being reduced.

Among those in the cohort who had pre-operative SRT, 88 per cent completed both stages of treatment, compared to only 73 per cent in the post-operative SRT patients, while the median gap between the two treatments was only six days for the pre-operative SRT group, compared with 22 for the other group.

Implications for Private Cancer Treatment

As with any study of this type, it will require peer review and further research will be needed to corroborate the findings. However, if it is confirmed that pre-operative SRT is the better option for patients with resectable metastases, it may become the standard procedure.

This kind of cutting-edge research is meaningful because the technology to carry out such work is now so advanced. SRT has been developed with increasing precision over the years, with tools like the Gamma Knife, first pioneered by Swedish scientist Lars Leksell in the 1960s, being enhanced with a second version in 1975 and further improved since.

Managing Side Effects of SRT

Both SRT and surgery will require significant recovery time and will come with a range of side effects. In the case of any radiotherapy treatment, common symptoms may include hair loss, nausea, vomiting, stomach troubles and loss of appetite, tiredness, skin problems and loss of libido.

It is worth noting, however, that not all of these symptoms will occur and some kinds of radiotherapy can produce certain side-effects more than others.

For example, blood-related issues caused by a reduction in blood cell production are commonly caused by external beam radiotherapy and internal isotope radiotherapy, because these impact the bone marrow where blood cells are produced. This is not, therefore, a common symptom of SRT.

What To Expect From Amethyst

The purpose of the study in the US was to find the best way to combine radiotherapy and surgery. In your own case, the brain cancer may not be metastatic, but the best treatment may still involve both SRT and surgery.

Where this is not the case, it will be because the cancer exists in the form of a tumour in a part of the brain that cannot be safely accessed in physical surgery. In this instance, SRT will have an even more important role to play.

What you can be sure of is that the treatment we offer will use the very best methods and knowledge at our disposal.

gamma knife treatment - Two doctors prepares the patient for the procedure on the Gamma Knife

Why Was Gamma Knife Stereotactic Radiosurgery Invented?

The ultimate goal of the surgeon is to do no harm, and in the field of cancer care and treatment, this means using the most precise, minimally invasive procedures and tools necessary to preserve and prolong life.

One of the greatest oncological innovations that abides by this principle is Gamma Knife, a highly advanced radiosurgical treatment that allows for tumours, lesions and malformations to be ablated and destroyed without the need for any incisions.

It differs from conventional radiotherapy because the precise nature of the system allows for suitable treatments to be completed in just one day, from consultation and planning to the computer-guided process itself.

The system was developed in the 1940s and 1950s by Lars Leksell (1907-1986), an innovative Swedish neurosurgeon who dedicated his life to making brain surgery more precise, more advanced and more effective.

The Aesthetics Of Healing

Interestingly, Professor Leksell did not intend to become a doctor, let alone one of the most important medical innovators of the 20th century. His desire to help people came about in part due to an unfortunate accident.

When he was a teenager, he was admitted to hospital following a car accident and his experiences with his doctors proved to be deeply inspirational to him that he signed up for medical school in 1927, becoming a neurosurgeon in the 1930s.

However, as his son would later note, Professor Leksell struggled with the operating theatre as it existed in the 1930s and wondered if a different form of surgery might be possible.

In part, this desire came from a general belief that less invasive procedures are typically safer, but it also came from a place of aesthetics.

Such surgeries were cleaner, more intricate and involved far fewer scars and lingering aftereffects; the only marks that are found after Gamma Knife treatment are from the bolts used to secure the frame in place.

By 1935, this became his driving force, and for the next 20 years, he would develop, refine and start to perfect the next step in brain cancer surgery.

3 Steps To Radiosurgery

Aside from radiotherapy itself, there were two other major innovations that helped Professor Leksell in this ambition to treat brain conditions.

The first was the Horsley-Clarke Frame, initially developed as a tool used to help create atlases of animal brains by allowing for precise measuring for incisions.

Invented in 1908 by Victor Horsley and Robert Clarke, the stereotactic frame would be adapted for use on the human brain a decade later, but it would take until 1933 for the stereotactic method to be used in neurosurgery.

This second innovation was thanks to surgical pioneer Martin Kirschner, who used a type of stereotactic frame to perform a procedure to treat the pain syndrome trigeminal neuralgia.

Before precise radiation application at the precision required for use in the brain was available, Dr Kirschner used a minimally invasive surgical procedure to insert an electrode to a precise location in the trigeminal nerve and burn it. This procedure is now typically undertaken using radiosurgery.

Both of these technologies would be more widely recognised and adapted in the late 1940s, when an adaptation of the Horsley-Clarke frame was used to map the human brain for the first time, thanks to the work of Ernest Spiegel and Henry Wycis.

Their innovative human brain atlas would inspire a lot of researchers in the field of stereotaxy, including Lars Leksell.

He first adapted the frame to use a polar coordinates system rather than the Cartesian measurements that had been used since 1908, which made it much easier to use in an era before CT scans were common.

He then found a way to use it to make radiotherapy more precise.

No Tool Is Too Refined

The idea behind stereotactic radiosurgery is that if you know exactly where to focus a point of radiation, it is safer and more effective to target multiple beams of radiation onto a single point rather than one.

This ultimately proved to be very effective, with successful trigeminal neuralgia cases treated as early as 1953. However, from its invention up until Professor Leksell’s retirement in 1974, he continued to adapt, refine and upgrade the frame.

His guiding principle for this, and one of his most famous quotes, was the idea that any tools that a surgeon uses have to be adapted to suit the task, and there is no tool that is too refined when it comes to treating the brain.

Who Was The First Ever Person Treated With Chemotherapy?

The first treatment for cancer that comes to mind to people who are not necessarily familiar with oncology is chemotherapy, and private chemotherapy treatment is not only highly effective but also focuses on ensuring a high quality of life before, during and after the course is complete.

There are a lot of different types of chemotherapy, but they work by using particular treatment agents to inhibit the growth or damage the DNA of cancerous cells, which is taken in cycles to break down and kill a cancerous tumour.

It can be undertaken on its own or in combination with radiotherapy to enhance its effect, radiosurgery or conventional surgery to kill any existing cancer cells following the destruction or excision of the tumour.

There are countless chemotherapy treatments and the right one for you will depend in large part on the type of cancer you have, its current progression, your overall health and your personal wishes when it comes to how you want to be treated. We are there every step of the way.

It is the newest of the three most established treatment pathways for cancer, with surgery and radiotherapy respectively being technically older but having changed significantly in the century since they were first used.

Chemotherapy was the result of an accidental discovery of a beneficial side effect of a chemical agent designed to cause harm.

The Development Of Chlormethine

The beginning of chemotherapy begins with the ancestor of chlormethine, a specialist drug that is either injected or used topically to treat certain types of skin cancers such as lymphoma, polycythaemia vera and some types of lung cancer.

Chlormethine, sometimes known as Mustargen, was originally derived from a much more harmful compound designed not to treat cancer but to cause harm: mustard gas.

Initially discovered in the 1860s by Frederick Guthrie, it was manufactured by Franz Haber and used in the First World War as one of the first modern chemical weapons ever deployed.

Whilst the harm mustard gas caused was immeasurable, and it was first banned in 1925 for that reason, there was also a rather interesting side effect found that it could also kill cancer cells in the lymph nodes in studies on its physiological effects.

The phenomenon was first discovered in 1919 by Dr Edward Krumbhaar, but it was not until the 1940s that these findings were fully applied to the treatment of cancer.

Early studies in mice, later confirmed in rabbits with lymphoma, confirmed its potential therapeutic properties once the sulphur used to make mustard gas was replaced with the less volatile nitrogen to create nitrogen mustard, which would become chlormethine.

Patient JD

The first human patient to ever be treated with chemotherapy was a man known as JD, living in Connecticut having been born in Poland.

Born in 1894, he emigrated to the United States and worked in a factory that manufactured ball bearings until he became ill in 1940 with non-Hodgkin lymphoma, then described as lymphosarcoma.

It was particularly aggressive, causing swelling throughout the right side of his neck, requiring 16 consecutive days of external beam radiotherapy using X-rays in 1941, before undergoing surgery to remove some of the tumours.

By 1942, the case had seemingly become terminal; the tumours were unresponsive to treatment, and the placement of the tumours made it particularly difficult to treat.

Out of options, JD’s doctors allowed for the use of chlormethine, known as “substance X” to ensure secrecy. This was the first use of chemotherapy to treat cancer, and the results were rather astonishing.

An unresponsive cancer had drastically reduced after five days, and despite struggling to breathe before the treatment, he found it easy to move his head and eat comfortably without difficulty. It had not only saved his life but given him his life back.

Unfortunately, whilst it was the right treatment, it was ultimately too late, and JD passed away 96 days following his first dose of treatment due to a relapse in the cancer at the age of 48.

A Legacy Of Lifesaving Care

JD’s story mirrors that of the unnamed 52-year-old patient of Victor Despeignes who in 1896 was the first person with cancer to be treated using X-rays. Once again, the treatment was remarkably effective but arrived too late to help.

Their bravery and willingness to try a treatment that was experimental at the time have contributed to the saving of millions of lives by proving the effectiveness of both treatments.

It led to the development of other chemotherapy medications, and within the decade following the Second World War, chemotherapy became an established treatment practice. By 1965 and the development of combination chemotherapy, cancer care was transformed forever.

What Is Brachytherapy And When Is It Used To Treat Cancer?

Treating cancer using radiation therapy is about using precisely managed and targeted radioactivity to destroy malignant tissue whilst sparing healthy tissue surrounding it.

In some cases, this is undertaken using an external radiotherapy beam, such as with the Gamma Knife method. However, there are other cases where the most precise way to deliver doses of radiation is from within using brachytherapy.

Also known as internal radiation, brachytherapy is often used to provide high-dose radiotherapy safely and in a short space of time, but exactly when and where it is most appropriate to use it will often depend on the needs of an individual person and their particular diagnosis.

What Is Brachytherapy?

Brachytherapy uses a source of radiation placed close to the cancer or to where a cancerous tumour has been removed following surgery.

The name brachytherapy comes from the Greek word ‘brachys’, which means ‘short-distance’, and unlike external beam radiotherapy, which often has to pass through several layers of tissue and body matter before reaching a tumour, brachytherapy is placed close to or directly onto the cancer itself.

There are multiple forms of brachytherapy, but they are typically categorised as either high dose rate (HDR) or low dose rate (LDR) which are either temporarily applied or implanted in the body respectively.

HDR brachytherapy usually involves the use of an applicator tube or needle inserted into the body before a radioactive material travels towards it and remains there for as little as five minutes before returning to the source.

By contrast, LDR involves the implantation of radioactive seeds, discs or other tiny pieces of material typically smaller than a grain of rice. This is typically applied using wires or needles and can be either temporary or permanent depending on the type of treatment.

When Was Brachytherapy First Used?

Brachytherapy is the first practical form of radiotherapy, as whilst experimental treatments using X-rays were tried mere months after Wilhelm Roentgen’s discovery, the use of radioactive materials was suggested in 1901 by Pierre Curie.

The use of radioactive seeds, initially made from radium sulphate, was pioneered in the early 1900s thanks to the work of William Duane, and a very similar system of application is still used to this day.

Before the development of external-beam radiation, CT and MRI scans which allow modern forms of external radiotherapy to be accurate and safe, brachytherapy was the standard treatment path for several forms of cancer.

Whilst its uses are more specific today, it still has some advantages that make it a viable option for oncologists in certain cases.

What Are The Advantages Of Brachytherapy?

There are several advantages to using brachytherapy, both in HDR and LDR forms, as they can provide higher doses of radiation with a greater degree of flexibility or adaptation compared to some types of external beam radiotherapy treatment.

Brachytherapy is inherently localised; the radiation source is placed directly on the cancer or as close as possible, which means that healthy tissue is less exposed to radiation, reducing potential damage and recovery times.

This localisation can also reduce treatment times significantly; whilst some radiotherapy treatments can take several hours, brachytherapy can take as little as five minutes and typically takes no more than 20, which allows for multiple treatments per day or for a course to be completed more quickly.

As well as this, in cases where the tumour shifts position in the body, something that can be common with cancers that affect the digestive, urinary and reproductive systems, the radioactive implants will move with the cancer and stay in the same position.

Both of these elements reduce the ability of cancer cells to recover and multiply between treatment sessions, and this can sometimes mean that a treatment that would ordinarily require a patient to spend time in a hospital can be completed in an outpatient setting.

When Is It Used To Treat Cancer?

It is typically used to treat cancers within body cavities or close to the skin, with the most common treatments focusing on cancers of the cervix, prostate, skin and breast. The easier it is to access a tumour, the greater the chance that brachytherapy can be used.

Generally, it is used to treat early-stage cancer before it has a chance to spread or metastasise, as it is a well-known, advanced, safe and often painless procedure, or it can sometimes be used following other more intensive cancer treatments to destroy any lingering cancer cells.

Permanent low-dose seed implantation is a standard treatment for localised prostate cancer, as it is less invasive than other treatments and a person can return to normal in just a few days.
