Atlas-based Autosegmentation

Elekta recently launched ABAS (Atlas-based Autosegmentation) 2.0 software, which includes the Simultaneous Truth and Performance Level Estimation (STAPLE) algorithm to increase contouring accuracy. ABAS—considered the industry gold standard for autosegmentation accuracy—deforms atlases of anatomy previously defined on a reference image onto a new patient image, creating a new structure set fit to the patient anatomy and enhancing planning efficiency.

“The STAPLE algorithm allows multiple atlases to be calculated against a single patient,” says Randy Larson, ABAS product manager. “The benefit is increased accuracy because the user is achieving the best result for each contour based on multiple sources. ABAS 2.0 also uses a graphics processor unit [GPU], which increases contouring speed by up to 50 percent. In addition, this release includes an improved user interface featuring new tools and functionality, as well as full DICOM service, to enhance workflow and file maintenance.”

With its deformable registration algorithms, ABAS saves physician and dosimetrist time by automatically contouring new image sets based on anatomy defined in the atlas. Users may further edit and refine the new image sets.

User-definable atlases allow clinicians to select an atlas that accurately reflects a given patient in a particular clinic. Atlases also can be patient-specific to account for change in size, shape or deformation during treatment. The algorithm completes multiple phases of refinement for increased accuracy.

Very few areas of medicine are changing faster than cancer care and Seattle physicians and researchers are leading the way.

A patient with pancreatic cancer at the Swedish Cancer Institute (SCI) recently became the first person in the United States to be treated with a new technology known as Volumetric intensity Modulated Arc Therapy (VMAT). VMAT cuts radiation treatment times by one-half to two-thirds through delivering a higher and more targeted dose to cancerous tumors, without compromising patient safety. To date, more than 10 patients have been treated with VMAT at the Swedish Cancer Institute. They have included patients with tumors of the brain, abdomen and pelvis.

“VMAT allows the delivery of higher radiation doses with greater precision. We will kill more cancer and patients will have fewer side effects,” said Vivek Mehta, M.D., director of SCI’s Center for Advanced Targeted Radiation Therapies.

Faster treatment times often mean improved comfort for patients, making it easier for them to remain still during the process. For the first VMAT patient, total treatment time was less than 10 minutes. More important, Dr. Mehta’s team was able to greatly reduce the radiation exposure to surrounding sensitive areas – including the spinal cord, left and right kidneys and the liver.

Dr. Mehta is the principal investigator on a VMAT clinical study that will last approximately six months and involve at least 20 separate patients. Part of the study’s purpose is to prove definitively that VMAT is both faster and safer than the existing treatment approach.

With VMAT, Swedish clinicians are able to treat more patients with complex cancers than they could in the past. That includes those who have had radiation therapy previously with limited success and patients with tumors adjacent to critical structures in the body. Also, the technology should benefit patients who find it difficult to lie completely still for the typical 30 or more minutes of treatment time.

Dr. Mehta estimates that 10 percent to 15 percent of people now treated at the Swedish Cancer Institute will be good candidates for VMAT.

Swedish clinicians are working closely with VMAT developer Elekta. “I believe we were chosen as the first North American site because Swedish has a proven track record of innovation in cancer care,” Dr. Mehta said. “Medical manufacturers often come to SCI’s Center for Advanced Targeted Radiotherapy with novel ideas and we select the technologies that have the greatest potential to improve treatment and save lives.”

What’s on the horizon?

Dr. Mehta believes the next innovation will be some form of adaptive radiotherapy. By borrowing software from other disciplines, clinicians may be able to see the results of the radiation therapy within 30 to 60 seconds and adapt their treatment plans instantly. Instead of viewing an image of the tumor in week one of treatment and not again for the typical six weeks, physicians could make near real-time corrections to both radiation targeting and dosage.

“We can cure about half of the patients we see, many of whom have very serious cancers. That is far better than a generation ago, but we need to keep improving outcomes for the other 50 percent,” said Dr. Mehta. “As the largest and most comprehensive cancer treatment program in the Pacific Northwest, that is our sole mission.”

Parietal Meningioma

Parietal Meningioma

Patient history and diagnosis

A 51 year-old male presented with enlarging lump on the top of his head, a short history of increasing headaches and some numbness affecting his left limbs. He also had bilateral blurring of the optic disc but no long tract deficits. A CT scan showed a large right parietal parafalcine mass and MR angiogram confirmed obstruction of the anterior and middle parts of the superior sagittal sinus. The tumor was removed leaving a large skull defect which was later closed with a titanium cranioplasty in November 2001. Histology showed an atypical meningioma with numerous mitosis. The patient had a recurrence of this tumor in December 2002 which was eventually resected again in May 2004. Further surgery was required in November 2004 for a recurrence posteriorly, after which the patient was referred for post-operative radiation therapy in view of his rapid recurrence.

Planned treatment

The patient was treated using HeadFIX® stereotactic head frame to accurately reproduce the daily treatment position. A three-field treatment technique was used comprising right and left lateral and a superior oblique treatment field, all with MLC beam shaping and wedges. The treatment was planned at 6MV using the Philips Pinnacle® planning system to deliver a total tumor dose to the isocenter of 50cGy in 25 fractions, with great care being taken to avoid any unnecessary dose to the eyes, optic nerves and brainstem.

WHAT IS HODGKIN’S DISEASE?

Hodgkin’s disease is a type of lymphoma. Lymphomas are cancers that develop in the lymphatic system, a part of the body’s immune system. The job of the lymphatic system is to help fight diseases and infection.

The lymphatic system includes a network of thin tubes that branch, like blood vessels, into the tissues throughout the body. Lymphatic vessels carry lymph, a colorless, watery fluid that contains infection-fighting cells called lymphocytes. Along this network of vessels are groups of small, bean-shaped organs called lymph nodes that filter the lymph as it passes through the nodes. Clusters of lymph nodes are found in the underarm, groin, neck, and abdomen. Other parts of the lymphatic system are the spleen, thymus, tonsils, and bone marrow.

Like all types of cancer, Hodgkin’s disease affects the body’s cells. Healthy cells grow, divide, and replace themselves in an orderly manner. This process keeps the body in good repair. In Hodgkin’s disease, cells in the lymphatic system grow abnormally and can spread to other organs. As the disease progresses, the body is less able to fight infection.

Hodgkin’s disease is rare. It accounts for less than 1 percent of all cases of cancer in this country. It is most often seen in young people aged 15 to 34 and in people over the age of 55. Other cancers of the lymphatic system are called non-Hodgkin’s lymphomas.

WHAT ARE SYMPTOMS OF HODGKIN’S DISEASE?

The most common symptom of Hodgkin’s disease is a painless swelling in the lymph nodes in the neck, underarm, or groin. Other symptoms may include fevers, night sweats, tiredness, weight loss, or itching skin. However, these symptoms are not sure signs of cancer. They may also be caused by many common illnesses, such as the flu or other infections. But it is important to see a doctor if any of these symptoms lasts longer than 2 weeks. Any illness should be diagnosed and treated as early as possible, and this is especially true of Hodgkin’s disease.

HOW IS HODGKIN’S DISEASE DIAGNOSED?

If Hodgkin’s disease is suspected, the doctor will ask about the patient’s medical history and will perform a thorough physical exam. Blood tests and x-rays of the chest, bones, liver, and spleen will also be done.

Tissue from an enlarged lymph node will be removed. This is known as a biopsy and is the only sure way to tell if cancer is present. A pathologist will look at the tissue under the microscope for Reed-Sternberg cells, abnormal cells that are usually found with Hodgkin’s disease. When Hodgkin’s disease is diagnosed, the doctor needs to know the stage, or extent, of the disease. Knowing the stage is very important for planning treatment. The stage indicates where the disease has spread and how much tissue is affected. In staging, the following are checked:

1. The number and location of affected lymph nodes
2. Whether the affected lymph nodes are above, below, or on both sides of the diaphragm (the thin muscle under the lungs and heart that separates the chest from the abdomen)
3. Whether the disease has spread to the bone marrow, to the spleen, or to places outside the lymphatic system, such as the liver

In staging, the doctor usually order several tests, including biopsies of the lymph nodes, liver, and bone marrow. Many patients have lymphangiograms, x-rays of the lymphatic system using a special dye to outline the lymph nodes and vessels. Another test is computed tomography (also called CT or CAT scan), a series of x-rays of cross-sections of the body.

HOW IS HODGKIN’S DISEASE TREATED?

Treatment for Hodgkin’s disease usually includes radiation therapy or chemotherapy. Sometimes, both are given. Treatment decisions depend on the stage of disease, its location in the body, which symptoms are present, and the general health and age of the patient (treatment for children with Hodgkin’s disease is more complex and is not discussed here).

Often, patients are referred to doctors or medical centers that specialize in the different treatments of Hodgkin’s disease. Also, patients may want to talk with their doctor about taking part in a research study of new treatment methods.

Radiation therapy uses high-energy rays to damage cancer cells and stop their growth. Radiation therapy is generally given in a hospital or clinic. Most often, patients receive radiation therapy 5 days a week for several weeks as outpatients.

Chemotherapy is the use of drugs to kill cancer cells. To treat Hodgkin’s disease, the doctor prescribes a combination of drugs that work together. The drugs may be given in different ways: Some are given by mouth; others are injected into an artery, vein, or muscle. The drugs travel through the bloodstream to almost every part of the body. Chemotherapy is usually given in cycles: a treatment period followed by a rest period, then another treatment period, and so on.

WHAT ARE THE SIDE EFFECTS OF TREATMENT FOR HODGKIN’S DISEASE?

The methods used to treat Hodgkin’s disease are very powerful. That is why the treatment often causes side effects – both short-term and permanent. Side effects depend on the type of treatment and on the part of the body being treated. Also, each patient may respond differently.

During radiation therapy, patients can become unusually tired as therapy continues. Resting as much as possible is important. Skin reactions (redness or dryness) in the area being treated are common. Patients should be gentle with the treated area of skin. Lotions and creams should not be used without the doctor’s advice. When the chest is treated, patients can have a dry, sore throat and have trouble swallowing. Sometimes they have shortness of breath or a dry cough. Radiation treatment to the lower abdomen can cause nausea, vomiting, or diarrhea. Some patients have tingling or numbness in their arms, legs, and lower back. These side effects gradually disappear when treatment is over.

The side effects of chemotherapy depend mainly on the drugs that are given. In general, anticancer drugs affect rapidly growing cells, such as blood cells that fight infection, cells that line the digestive tract, and cells in the hair follicles. As a result, patients can have side effects such as a lowered resistance to infection, nausea, vomiting, or mouth sores. They can also have less energy and may their hair.

Loss of appetite can be a problem for patients receiving radiation therapy or chemotherapy. Researchers are learning that patients who eat well may be better able to tolerate the side effects of their treatment. Therefore, nutrition is an important part of the treatment plan. Eating well means getting enough calories to prevent weight loss and having enough protein in the diet to build and repair skin, hair, muscles, and organs. Many patients find that eating several small meals and snacks throughout the day is easier than trying to have three large meals.

Treatment for Hodgkin’s disease can cause fertility problems. Women’s menstrual periods may stop. Periods are more likely to return in younger women. In men, both Hodgkin’s disease and its treatment can affect fertility. Younger men are more likely to regain their fertility. Sperm banking before treatment can be an option for some men.

The side effects that patients have during cancer therapy vary from person to person and may even be different from one treatment to the next. Attempts are made to plan treatment to keep problems to a minimum. Doctors, nurses, and dietitians can explain the side effects of cancer treatment and can suggest ways to deal with them.

WHAT HAPPENS AFTER TREATMENT FOR HODGKIN’S DISEASE?

Regular follow-up exams are very important for anyone who has been treated for Hodgkin’s disease. The doctor will want to continue to watch the patient closely for several years. Generally, checkups include a thorough physical exam, x-rays, blood tests, and other laboratory tests.

Patients treated for Hodgkin’s disease have an increased risk of developing other types of cancer later in life, especially leukemia. Patients should follow their doctor’s recommendations on health care and checkups. Having regular checkups allows problems to be detected and treated promptly if they should arise.

When people have cancer, life can change for them and for the people who care about them. These changes in daily life can be difficult to handle. It is natural for a person with Hodgkin’s disease to have many different and sometimes confusing emotions.

At times, patients and family members may be depressed, angry, or frightened. At other times, feelings may vary from hope to despair or from courage to fear. Patients usually are better able to cope with their emotions if they can talk openly about their illness and their feelings with family members and friends.

Concerns about the future, as well as about medical tests, treatments, a hospital stay, and medical bills, are common. Talking to doctors, nurses, or other members of the health care team can help to ease fear and confusion. Patients can take an active part in decisions about their medical care by asking questions about their treatment. Patients and family members often find it helpful to write down questions for the doctor as they think of them. Taking notes during visits to the doctor can help them remember what was said. Patients should ask the doctor to explain anything that is not clear.

Patients have many important questions to ask about their disease, and their doctor is the best person to provide answers. Most people want to learn how Hodgkin’s disease can be treated, how successful the treatment is likely to be, and how much the treatment is expected to cost.

The patient’s doctor is the best person to give advice about working or limiting other activities, but it may be hard for some people to talk to the doctor about their feelings and other very personal matters. Many patients find it helpful to talk with others who are facing similar problems. This kind of help is available through cancer-related support groups. It also may be helpful to talk with a nurse, social worker, counselor, or member of the clergy.

WHAT DOES THE FUTURE HOLD FOR PATIENTS WITH HODGKIN’S DISEASE?

More than 8 million Americans living today have had some type of cancer. Thirty years ago, few patients with Hodgkin’s disease recovered from their illness. Now, because of modern radiation therapy and combination chemotherapy, more than 75 percent of all newly diagnosed Hodgkin’s disease patients are curable. The chances for recovery continue to improve as scientists find new and more effective treatments.

Doctors often talk about “surviving” cancer, or they may use the word “remission” rather than “cure.” Even though many patients recover completely, doctors use these terms because Hodgkin’s disease can recur. Patients are naturally concerned about their future and may try to use statistics they have read or heard about to try to figure out their own chances of being cured. It is important to remember, however, that statistics are averages based on the experiences of large numbers of people, and no two cancer patients are alike. Only the doctor who takes care of a patient knows enough about that person to discuss the prognosis.

Scientists at hospitals and medical centers all across the country are studying Hodgkin’s disease. They are trying to learn more about the possible causes of the disease and how it might be prevented.

In addition, scientists are exploring new methods of treatment, including new drugs, drug combinations, and combinations of radiation therapy and chemotherapy. Other methods, such as bone marrow transplantation and biological therapy, are being studied with some Hodgkin’s disease patients in clinical trials. These trials are designed to answer scientific questions and to find out whether a promising new treatment is both safe and effective. Patients who take part in clinical trials make an important contribution to medical science and may have the first chance to benefit from improved treatment methods.

This guide contains information on frequently asked questions and information on the treatment process. While this information will not necessarily correspond to the exact process adopted by an individual hospital, we hope it will provide general background information and an indication of a typical treatment process.

Who will be looking after me?

A specialist cancer doctor is known as a radiotherapist or radiation oncologist. In this guide we will refer to him/her as an radiation oncologist. The radiation oncologist will plan and oversee your treatment, which will be carried out by radiation therapists. In addition, the team looking after you may include nurses, health care assistants, specialist nurses, counsellors and dietitians, according to your needs during your treatment.

What is radiation therapy?

Radiation Therapy is the treatment of cancer with radiation. This can be done in a variety of ways, depending on the nature of your cancer. The most commonly used method is called external beam therapy (from a machine outside the body), which directs radiation at your tumor.

How does radiation therapy work?

Radiation Therapy Treatment Process

Radiation Therapy Treatment Process

Although the radiation affects both cancer and normal cells, it has a greater effect on the cancer cells. Treatment aimed at cure will give the highest possible dose of radiation to the cancer area (within safe limits) to attempt to kill all the cancer cells. Sometimes smaller doses are used, where the aim is to reduce the size of a tumor and/or relieve symptoms.

How is the treatment planned?

Every course of radiation therapy is designed to suit the particular needs of the person receiving it, so you will usually be asked to make a preliminary visit to the treatment center to have your course of treatment planned. The radiation oncologist and radiation therapists will do this (in conjunction with x-rays and scans, using a machine called a simulator). Your skin will be marked with coloured pens to define where you will have your treatment. In addition, some minute permanent marks will be made using a special dye and a tiny pin prick.

These marks will enable the radiation therapists to identify exactly the right area at every treatment session. If a head shell has been made for you the guidance marks will be put on the shell rather than on your skin.

If you are having radiation therapy to your mouth and/or throat you will need a dental assessment at this stage as you may require some dental treatment before you start your radiation therapy.

How is radiation therapy given?

Radiation therapy is given using either a machine called a linear accelerator or, for some skin tumors, a superficial x-ray unit. To receive the radiation therapy, you will lie on a couch under the machine, and be asked to remain still during the actual treatment.

Will the radiation therapy hurt?

Radiation Therapy Treatment Process

Radiation Therapy Treatment Process

No. The treatment is completely painless. Radiation cannot be seen or felt while it is being given.

Will the treatment make me radioactive?

No. There is no possibility of this whatsoever.

How long will the course of treatment last?

Your radiation oncologist will tell you this once the appropriate treatment for you has been decided. A course can last for anything from a single treatment to five treatments a week for six weeks depending on a number of factors, e.g. the part of your body being treated and the aim of the treatment. Most treatments are carried out daily between Monday and Friday.

How long is each treatment session?

This varies from machine to machine. Some machines operate at a faster rate than others, and it also depends on the plan worked out for you. The length of a treatment session can be anything from five minutes to fifteen minutes. Occasionally a session may take longer, but this will be explained on an individual basis. When you come for your first treatment your radiation therapist will tell you how long each session will take.

Do I have to stay in hospital?

If you are able to travel to the hospital for treatment there is usually no need for you to be admitted during the course. Most people are treated as outpatients, but your radiation oncologist will tell you if it would be better for you to be admitted.

Will I have any tests during treatment?

Radiation Therapy Treatment Process

Radiation Therapy Treatment Process

During your course of treatment, you may need to have occasional blood test and/or urine test, depending on the part of your body being treated. Some people also have X-rays and/or scans during their course of treatment, which is part of the routine and nothing to worry about.

Are there particular things I should or should not do during my course of treatment?

As far as possible throughout your treatment, try to lead a normal life – try to think of the radiation therapy as an interruption to your daily routine rather than as the most important part of your day. However, the following tips might help:

Do

* Drink plenty of fluids every day during treatment, e.g. tea, coffee, milk, fruit juice, water or fizzy drinks (ideally sugar-free).
* Eat regularly and try to keep a balanced diet. If you don’t feel like big meals, try eating little and often. The dietitian can help to plan a diet for you if necessary.
* Wash, shower or bath as normal during treatment using a simple or baby soap taking care to pat dry the area being treated, rather than rubbing it.


Do Not

* Drink spirits, eat spicy food or very hot or very cold food if you are having treatment to your mouth, neck or chest, but ask the radiographers if you would like more information.
* Expose the treated area to the sun during a radiation therapy treatment course, as the treated area will burn more easily and take some time to heal. In the future it is advisable always to apply sunscreen to avoid sunburn.
* Put creams or deodorants on the treated area as these may worsen your skin reaction.

Am I likely to have any side effects?

Radiation therapy is a localized treatment, which means that any side effects will depend on the part of the body being treated. Although many people have few, if any, side effects, everyone reacts differently and during your treatment you may experience one or more of the following:

* Tiredness:

Radiation Therapy Treatment Process

Radiation Therapy Treatment Process


You may feel tired and lethargic during your treatment and especially towards the end of the course and after it has finished. This is very common, and can last a variable length of time. If it happens to you, pace yourself and rest as much as you feel you need to and gradually the tiredness will pass, although it may take a long while.

* Tender skin:
During your treatment and especially towards the end of your course, your skin in the area being treated may turn red, like mild sunburn, and tenderness and redness may even increase for a week or two after your treatment has finished (this is because the tissues continue to be affected by the x-rays for several weeks after treatment.). It will gradually recover, but the nurse or radiation therapist treating you will explain exactly how you should look after your skin, during and after your course of treatment.

* Sickness:
Depending on the part of your body being treated you may feel nauseous or be sick during your course of treatment. This does not happen to everyone. If you do feel sick, please tell your radiation therapist or nurse as it can be controlled by tablets or diet.

* Diarrhoea:
Again, depending on the part of your body being treated, you may experience some diarrhoea. Please tell your radiation therapist or nurse if this happens to you as you may need diarrhoea-relieving medication.The dietitian will also be pleased to advise you and help you with an eating plan if necessary.

* Frequency when passing urine:
If you are having treatment to your lower abdomen/pelvis you may find that you pass urine more often and may experience discomfort when doing so. Drinking extra fluids will help, but try to avoid alcohol, tea and coffee as these can irritate your bladder. If this happens to you please tell the staff treating you, so that your urine can be tested for any infection,which could then be treated with appropriate medication.

* Sore mouth and throat:

This only happens if you are having treatment to this part of your body. If it is likely to be a problem your radiation therapist or nurse will explain how to look after your mouth and throat, or give you advice on chewing and swallowing difficulties. This only happens if you are having treatment to this area. If it is likely to be a problem, your radiation therapist or nurse will explain to you how to look after your mouth and throat during treatment.

* Hair loss:
Hair loss only occurs where treatment is given. For example you will only lose the hair on your head if your head is being treated, and if your chest is being treated, then you will only lose your chest hair. Whether or not it grows again will depend on how much radiation you have been given. Your oncologist will explain what this means for you. If your hair is expected to grow again, this should happen within a few months of the end of your treatment.

Can I carry on working?

If you feel you wish to carry on working, as long as your radiation oncologist reason why you should not continue with your normal daily course of treatment. However do ask if you need advice.

What will happen when the treatment is finished?

Radiation Therapy Treatment Process

Radiation Therapy Treatment Process

The immediate side effects of the treatment described above will start to ease off within a week or two of the end of your course. Because of the way radiation therapy works, the full benefit of the course of treatment is not usually reached until some weeks after the last treatment session.

Will I have any check-ups after my treatment?

After your treatment, you will be seen again at the hospital you first attended or be referred back to your Family Doctor. The first follow-up is often about 4 to 6 weeks after the course has finished, and this appointment will be discussed with you before you finish at the treatment center. However, follow-up arrangements can vary from person to person and from centre to centre. Your radiation oncologist will explain to you how and where your follow-up appointments will be arranged.

Can radiation therapy cause permanent damage?

Radiation therapy treatment is planned and delivered with the utmost care, but sometimes sensitive parts of the body are damaged. This is because to treat the cancer effectively, it is sometimes necessary to use high doses of radiation, close to the limits that normal tissues can withstand. The bowel, bladder and nervous system are particularly sensitive, but other parts of the body can suffer long term changes.

If you are having radiation therapy aimed at killing your cancer cells, there is about a 5% possibility of side-effects which may seriously affect your lifestyle. However, it is important to balance this against the much higher potential risks to your life, from the cancer getting worse or recurring without the treatment. On the other hand, if you are having radiation therapy to shrink the tumour and/or relieve symptoms, then the much lower doses of radiation used are unlikely to cause any permanent damage.

If the radiation therapy treatment includes the gonads (ovaries in women, testicles in men) this will affect fertility and hormone function. It is important to discuss this with your oncologist before treatment begins.

If you do have any difficulties at any time in the future which you feel may be connected with your radiation therapy, then do not hesitate to contact your oncologist or GP. If there are any special risks or problems in your case then your oncologist will discuss this with you. Bear in mind that you are being offered radiation therapy because the benefits greatly outweigh the risks.

The creation of Elekta Synergy was driven by the need to visualize internal structures, including soft tissues, in three dimensions within the reference frame of the treatment system and at the time of treatment. This will allow the clinician to minimize geometric uncertainties resulting from both organ motion/deformation and slight differences in patient set-up.

Elekta Synergy has therefore been designed to inspire clinical confidence via IGRT to practice advanced radiation therapy techniques. This combination of high resolution imaging, taken in 3D and at the time (the 4th dimension) of treatment – combined with workflow solutions developed to be applicable on a routine basis – is described as ‘4D Adaptive’ and is the Elekta® IGRT solution…..Read more about Elekta Synergy
