The Radiation Oncology Department at Beaumont is known nationally and internationally for developing new radiation therapy techniques and for expertise in treating prostate cancer. Radiation oncologists and physicists at Beaumont possess the technical skill and expertise to plan radiotherapy, handle radioactive sources, calculate doses, and coordinate care with other specialists. External beam radiation therapy (EBRT) – delivers X-rays (photons) from outside the body to the area to be treated. 3-D conformal pelvic radiotherapy delivers radiation to the prostate and surrounding pelvic lymph nodes.
3-D conformal prostatic fossa radiotherapy is sometimes recommended after prostate surgery. Intensity-modulated radiotherapy (IMRT) and ART combines 3DCRT with ART to deliver radiation treatment for prostate cancer. Beaumont was one of the first institutions to offer IMRT for the treatment of prostate cancer. Image-guided hypofractionated adaptive radiotherapy combines the conformal, IMRT and ART methods described previously  with real-time (online) image guidance.
Your radiation oncologist will discuss this radiation treatment for prostate cancer option with you if you meet eligibility requirements. As the researchers themselves identify, the type of vitamin E administered to the men in this study was a supplement made of all-rac-alpha-tocopherol acetate, a synthetic version of just one of the 8 natural compounds that together make up real vitamin E. This is not even remotely comparable to getting the full spectrum of vitamin E compounds found either in a natural diet with plenty of vitamin E rich foods, like nuts, seeds, and greens or in a supplement containing mixed tocopherols. Synthetic vitamin E is well known by medical researchers to be not only much less effective, but potentially harmful. Studies now show that gamma tocopherol plays a much more important role in humans, yet alpha tocopherol is still the type of vitamin E most likely found in many lower quality supplements. As noted above, what is really wanted is mixed tocopherols, which means that all the compounds that make up real vitamin E, are present. What is helpful are natural vitamins that offer health benefits and supplements that both men and women actually can use. The editors and researchers at Smart Publications review and analyze thousands of scientific studies per year, succinctly capturing and summarizing the results of these studies on their website, and in highly respected published books on health & wellness. In conducting the study, the researchers examined the medical records of more than 1,000 men diagnosed with prostate cancer who were being treated at a federally subsidized Veterans Affairs Medical Center.
The researchers specifically chose the VA hospital in order to eliminate speculation that treatment decisions were also bottom-line cost decisions.
Although men with prostate cancer who were also being treated for another co-existing medical issue (such as chronic obstructive pulmonary disease, diabetes and peripheral vascular disease) had lower survival rates than other men, their cancer was treated just as aggressively, the investigators found. The study revealed that of the roughly two-thirds of men who underwent aggressive treatment for prostate cancer, only 16 percent who had no other health problems died of other causes after 10 years. In contrast, 35 percent of men who also had diabetes died of causes not related to their cancer after 10 years. Similarly, 49 percent of men who also had peripheral vascular disease who were treated for their cancer were dead within 10 years, and 65 percent of men with moderate to severe chronic obstructive pulmonary disease also died. In taking the age of the men into account, however, the study revealed that only about 25 percent of 75-year-olds were being treated for their prostate cancer — even though they had a 58 percent chance of surviving another decade. For men older than 50, a simple blood test to screen for prostate cancer is as much a part of annual physicals as weigh-ins and stethoscopes.
Yet an influential commission charged with assessing medical treatments is recommending that routine screening be ended, to the furor of doctors, including the American Urological Association. The panel’s data make a compelling case that the overall societal benefit from widespread PSA screening is marginal, and it is not the first group to say so. It proposes eliminating the information that leads to over-treatment, rather than reforming the treatment itself. With the cost of American health care wildly out of control, the hunt is on to reduce unproductive treatments. The Sour Sop or the fruit from the graviola tree is a miraculous natural cancer cell killer 10,000 times stronger than Chemo. So, since you know it now you can help a friend in need by letting him know or just drink some sour sop juice yourself as prevention from time to time. How many people died in vain while this billion-dollar drug maker concealed the secret of the miraculous Graviola tree? Although it is effective for a number of medical conditions, it is its anti-tumor effect that is of most interest. Besides being a cancer remedy, graviola is a broad spectrum antimicrobial agent for both bacterial and fungal infections, is effective against internal parasites and worms, lowers high blood pressure and is used for depression, stress and nervous disorders. If there ever was a single example that makes it dramatically clear why the existence of Health Sciences Institute is so vital to Americans like you, it’s the incredible story behind the Graviola tree. The truth is stunningly simple: Deep within the Amazon Rain forest grows a tree that could literally revolutionize what you, your doctor, and the rest of the world thinks about cancer treatment and chances of survival.
If Graviola extract is as half as promising as it appears to be–why doesn’t every single oncologist at every major hospital insist on using it on all his or her patients? One of America ‘s biggest billion-dollar drug makers began a search for a cancer cure and their research centered on Graviola, a legendary healing tree from the Amazon Rain forest.
Various parts of the Graviola tree–including the bark, leaves, roots, fruit and fruit-seeds- -have been used for centuries by medicine men and native Indians in South America to treat heart disease, asthma, liver problems and arthritis.
It turns out the drug company invested nearly seven years trying to synthesize two of the Graviola tree’s most powerful anti-cancer ingredients. If they could isolate and produce man-made clones of what makes the Graviola so potent, they’d be able to patent it and make their money back.
As the dream of huge profits evaporated, their testing on Graviola came to a screeching halt. Even worse, the company shelved the entire project and chose not to publish the findings of its research! Luckily, however, there was one scientist from the Graviola research team whose conscience wouldn’t let him see such atrocity committed. Miracle unleashed When researchers at the Health Sciences Institute were alerted to the news of Graviola, they began tracking the research done on the cancer-killing tree. A limited supply of Graviola extract, grown and harvested by indigenous people in Brazil , is finally available in America. As a cancer patient that was diagnosed just four months ago, I would like to share my thoughts with those Kenyans that may yet to encounter this medical condition in one way or another. When in May 2011 I was diagnosed with Prostate Cancer at Aga Khan Hospital in Nairobi, I left the doctor’s clinic in a daze. Meanwhile in Nairobi, my nephews had gathered in my house and within one hour, we had identified a urologist who accepted to see me at short notice. Anybody experiencing any of all of these symptoms should seek medical help as soon as possible Advanced cancer treatment requires a combination of many things. The first stage is to carry out four major tests to ascertain the extent of the spread once the PSA level is confirmed.
It is therefore important that the doctor discusses in detail with the patient the results before any of these methods are applied because each one of them has serious side effects that can affect the patient for life. As a board-certified urologist and an oncologist specializing in the diagnosis and treatment of urologic diseases, kidney cancer, bladder cancer, and prostate cancer. He also specializes in many advanced minimally invasive treatments for prostate cancer, including his newest robotic surgery procedure, SMART Surgery (Samadi Modified Advanced Robotic Technique). In developing countries like Kenya, more deaths are caused by cancer than TB, malaria, HIV and AIDS combined. The medics then stopped the trial of 922 people, saying it was unethical not to offer all of them the treatment. Half were given the radium-223 chloride drug alongside traditional chemotherapy, while the other patients received chemotherapy and a dummy pill. The findings are being presented at the European Multidisciplinary Cancer Congress but they have not yet been peer-reviewed by other academics. Radiation Treatment For Prostate CancerSince I left Nairobi three weeks ago to seek further treatment for my prostate cancer in America’s advanced cancer institutions, I now have more information I can give to my friends, colleagues and followers of this column based on my observations and interactions with doctors and other social groups that are equally involved in the treatment of cancer in the United States of America. On arriving in Atlanta on June 20th 2011, I spent the first week booking appointments with Emory University Hospital Cancer Center, the Georgia Cancer Center and Radiotherapy Centers of the United States of America, all based in Atlanta area.
Although Emory University Hospital, Georgia Cancer Center and Radiotherapy Center are different and independent institutions, their ownership is jointly shared making specialists easily share information regarding the latest research findings, discoveries and unique cases they come across. Although under normal circumstances the capether should have been changed daily based on the USA standards, mine had been with me for close to six weeks. On reading my test reports in Nairobi and seeing that at the start of my treatment I had a PSA level of 817 and a Gleason scale of 7, he quickly referred me to an oncologist at Emory University Hospital the same afternoon who examined me then referred me to Dr. Founded over 30 years ago, the center specializes in Prostate Cancer Research but also conducts weekly talks to cancer patients so that they can be better informed of new methods of managing the disease.
What I discovered in my first meeting was that I was the only person whose PSA was 817 at the time of diagnosis. In the last 30 years, doctors at the RC Cancer Centers have treated more than 12,500 men for prostate cancer with a procedure called ProstRcision. Based on RC Cancer Centers’ extensive experience in managing Prostate Cancer, the center has developed literature containing 136 questions and answers to provide men diagnosed with prostate cancer and their families information they need to make informed decisions on how to be treated. Saw palmetto can help regulate your hormone levels especially with regards to testosterone.
PCAP is the organizer of Black Tire Affair events such as the Prostate Cancer It has its own symptoms and signs which may vary from patient to patient but what is common for all people with end stage of te disease Only Does Radiation For Prostate Cancer Cause Impotence the best funny Prostate jokes and best Prostate websites as selected and voted by visitors of Joke Buddha website a protein associated with epithelial tumors in breast ovarian pancreatic colon bladder and prostate cancers. The Prostacet Formula delivers key ingredients to nutritionally support a healthy prostate.
Having performd over 5600 successful prostate cancer treatments in his work Samadi’s experience is unparalleled.
Paradise truly holistic full spectrum saw palmetto 10:1 is the highest quality nature hs to offer.
Ray et al (2006) also looked at the relationship between the PSA nadir (nPSA) and eight year disease free survival.
Clearly the lower the final nadir, the better the long term prospects are of remaining disease free.
With hormone treatment, the PSA behaviour after the radiation treatment is even more uncertain.
PSA nadir predicts biochemical and distant failures after external beam radiotherapy for prostate cancer: a multi-institutional analysis.
Many of the radiation treatments for prostate cancer were pioneered or improved on by Beaumont doctors. You will lie on a table while the linear accelerator X-ray machine rotates around you, delivering painless radiation from multiple angles.
3DCRT outlines the prostate, as well as surrounding normal tissues such as the bladder and rectum.
This therapy is typically considered for higher-risk patients with confirmed or likely cancer spread beyond the prostate. Rather than relying on a single CT scan for positioning, radiologists at Beaumont perform a series of CT scans early in the treatment process. Intensity modulation changes the strength of the dose within each X-ray beam, dividing the beam into smaller “pencil” beams.
Many physicians and physicists from Beaumont have served as IMRT instructors for courses offered in the United States and around the world.
They place simulation CT scans on the treatment machine to image the prostate before turning on the X-ray beam, ensuring the highest level of precision.


Thats right, as seen before, researchers are basing their entire study on people taking this one constituent of vitamin E plus, as a synthetic form derived from petroleum products. Mixed tocopherols are the natural mix of compounds that make up real vitamin E, and they deliver important ingredients required for heart health, do not promote prostate cancer, and best of all, abundant clinical evidence exists to support real vitamin Es benefits. Studies, like this one, shows that the real headline here should read, Synthetic versions of vitamin E instead of real vitamin E pose health risks for men. Yes, if the vitamin supplement label lists vitamin E as: dl-alpha tocopherol, dl-alpha tocopheryl acetate, or dl-alpha tocopheryl succinate. If gamma tocopherol is listed, consumers can be confident it contains this most important and health-promoting type of vitamin E.
With the National Academy of Sciences recently recognizing natural vitamin E as the form of vitamin E that humans assimilate most effectively, understanding the facts versus the hype is what is needed to make healthy decisions.
29 (HealthDay News) — Men over 75 with prostate cancer who are otherwise healthy are being undertreated for their condition, according to a new study. Meanwhile, the study showed 50 percent of diabetic men who had organ damage related to the condition died within that time frame for reasons not cancer-related. In both of those situations, the men died for reasons not related to cancer, according to the findings published in the Sept.
On the other hand, if he has high-grade cancer, the disease might not be found until it has spread to other organs, which is fatal. And yes, the biopsies that typically follow a rise in PSA can be painful, but for most patients they’re not. This is necessary, says the panel’s chairman, Virginia Moyer, because once patients hear they have cancer, human nature drives them to demand aggressive action, necessary or not, and because engineering massive change in medical practices is a Herculean task. The prostate recommendation, like the commission’s equally controversial suggestion in 2009 to do fewer mammograms, is a measure of how difficult that discussion will be. Information about prostate cancer and its treatment is readily available from the National Cancer Institute, major cancer centers and other sources. Its because some big corporation wants to make back their money spent on years of research by trying to make a synthetic version of it for sale. The fruit is very large and the subacid sweet white pulp is eaten out of hand or, more commonly, used to make fruit drinks, sherbets and such. The amazing anti-cancer properties of the Graviola tree have been extensively researched– so why haven’t you heard anything about it? Risking his career, he contacted a company that’s dedicated to harvesting medical plants from the Amazon Rainforest and blew the whistle.
Unlike chemotherapy, which indiscriminately targets all actively reproducing cells (such as stomach and hair cells), causing the often devastating side effects of nausea and hair loss in cancer patients. The first thing that comes to my mind is that, when cancer strikes one family member, the entire family and close friends are deeply affected. Two hour later, the urologist confirmed a two year prostate cancer infection and immediately ordered for a PSA blood test. I therefore mistook them for the usual backache, abdominal pain, muscle pain, loss of appetite and general stomach disorders. He too pumped me with more wrong drugs for two good months as the cancer cells took their toll on my body. An MRI scan is a radiology technique that uses magnetism, radio waves, and a computer to produce images of body structures. It is the medical removal of tissue from a living subject to determine the presence or extent of a disease. For a cancer patient to recover even partially and undergo a long period of healing, the patient needs a peace of mind, a fighting spirit, family and friends support and a drastic change in diet and lifestyle. David Samadi discusses prostate cancer treatment in developing countries, as well as prostate cancer patients traveling to the U.S. Samadi is the Vice Chairman, Department of Urology, and the Chief of Robotics and Minimally Invasive Surgery at The Mount Sinai Medical Center in New York City. Kenyan statistics indicate 18,000 new cancer diagnoses each year, of which 50 people die each day.
Samadi believes Nyong’o to be among the growing number of patient ambassadors around the world. Samadi believes it is important to be part of the prostate cancer solution abroad and in the U.S. It is a barrage of helium nuclei, which are far bigger than beta radiation, a stream of electrons, or gamma waves.
Curiously there were fewer side-effects in the group taking the treatment than those taking the dummy medicine. He therefore chose to remove it and asked me to observe for at least 48 hours if I could do without it.
Peacock saw me, I had to fill a 16 page questionnaire detailing my family history, drug allergies and the drugs I had been taking since I was diagnosed with prostate cancer.
Peacock’s clinic, he referred me to a conference for Cancer patients organized by the RC Cancer Centers of the United States of America in Conyers.
These talks are attended by cancer survivors, patients under treatment and newly diagnosed cases. Because most Americans go for routine PSA checks, theirs are discovered before reaching level four PSA count. The foundation of the ProstRcision treatment programme has been long term research focused on cure rather than treatment of prostate cancer. In a nutshell, the Centers strives to provide a decision making process to enable the patient select the best treatment method for curing Prostate Cancer.
It is believed that factors can prostate cancer cause tailbone pain linked to aging and the testicles themselves may play a role in the growth of the gland.

Alan Garen professorof molecular biophysics and biochemistry at Yale has received a $100000 award from the Prostate Cancer Foundation to expand research on the delivery of a targeted therapy for prostate Whatever the stage of your cancer it is important to consider all of the options carefully and weigh the advantages Varunadi Vati – The Varuna is a tree and the bark of this tree is used in Ayurveda to fighting stage 4 prostate cancer lower down PSA levels and reduce the size of enlarged prostate gland. RegenePure DR is packed with other beneficial elements including Saw Palmetto extract Vitamin B6 and Zinc Oxide. Prostate treatment: superlative BPH treatment reverses prostate enlargement and prostate treatment relieves symptoms of chronic prostatitis London United Kingdom (PRWEB) July 19 2011. It should be noted that these two tables are only a summary of their results and their paper needs to be consulted for more complete details.
This radiation treatment for prostate cancer will not hurt, feel hot or cause you to be radioactive in any way. Sometimes the radiation oncologist will recommend planting tiny markers or seeds in the prostate to help with targeting. The scans track how the prostate and surrounding normal organs change position from day to day. Aiming these beams makes it possible to deliver high doses of radiation to target tissues, while delivering only low doses to tissues such as the bladder and rectum that should be protected. These courses are sponsored by professional organizations such as the Radiation Therapy Oncology Group (RTOG) and the American Society of Therapeutic Radiology and Oncology (ASTRO). The new technology has the potential to shorten radiation treatment courses from eight weeks to between one and four weeks. Klein, MD, claims to find a link between the popular antioxidant and one of the most common cancers in men.
Of these eight, alpha tocopherol was formerly thought to be the most potent compound for human health. It is very important to learn the facts about tocopherols before taking the wrong vitamin E. About Smart Publications Smart Publications clarifies the complex world of nutritional science. Smart Publications also has a growing reference area with helpful links to compounding pharmacies, alternative health doctors, lab services, government health updates, and sources for nutritional health solutions. Karim Chamie, a postdoctoral fellow in urologic oncology and health services research, said in a UCLA news release. Instead, it argues, with a formidable arsenal of data, that the test leads to widespread over-treatment, which outweighs the benefits of early detection.
The fact that his death might be statistically offset by the survival of someone who would have died from unneeded treatment is cold comfort. There was no way the company could protect its profits–or even make back the millions it poured into research. Here in Kenya, AAR, the medical insurance company dedicated the month of June to Prostate Cancer as their awareness month. In the middle of grief she told me that I could not die now because she could not visualize her life and children without me. It is therefore important that during this month of Kenya’s cancer awareness, doctors and diagnosed victims should join hands and educate the rest of Kenyans on basic prostate cancer symptoms so that anybody experiencing such disorders should go for a check-up as soon as possible in order to seek immediate medical attention.
The image and resolution produced by MRI is quite detailed and can detect tiny changes of structures within the body. The tissue is generally examined under a microscope by a pathologist, and can also be analyzed chemically. They find it easy to pick a phone and call another doctor if they find your case unique and unusual. Schnell’s office, the Medical Director of the Newton Country Radiation Therapy Center.
These were the gadgets that had been planted on my body in mid-May at MP Shah Hospital when I needed to ease pressure on my kidneys and detoxify my circulation system. To confirm that I was fine without one, he gave me a lot of liquid to drink and remained in the clinic for at least one hour to see if I could pass urine without the assistance of the capether.
In this category, I had to include any drug unauthorized by the Federal Drug Authority of the United States Government. From their research, over 80 research papers have been published and peer-reviewed in medical journals or presented at medical conferences. Does Radiation For Prostate Cancer Cause Impotence following the success of last year’s web chat this prostate cancer awareness month our leading expert Professor Mark Emberton is back once more to answer your questions about prostate Does Radiation For Prostate Cancer Cause Impotence cancer. Gleason Score: This is a grading system for prostate cancer made by looking at the prostate cancer cells prostate treatment centers under a Bone Tumour Patients. Xofigo is indicated for the treatment of adults with castration-resistant prostate cancer symptomatic bone metastases and no known visceral metastases.1. Taking saw palmetto along with estrogen pills might decrease the effectiveness of estrogen pills. There are other modes of ultrasound called Power Doppler TRUS or color amplitude imaging (CAI) Many products for BPH will combine nettle root with saw palmetto or pygeum extracts. It is commonly used for benign prostate enlargement but has also been used for handling other conditions. EBRT typically involves daily treatments, Monday through Friday, for approximately eight weeks.
This is why Beaumont developed a treatment method called “Adaptive Radiotherapy” (ART) to improve the accuracy of radiation delivery.
Consumers might be rightfully wondering whether their vitamin E supplement is still safe to use and what steps they should take in light of this new research.
Over the entire society, it says, there is no net gain and substantial damage to patients, ranging from needless worry, to impotence and incontinence, to death.
But in tallying the damage, the commission makes some relatively small problems seem very big.


During that period, they could test anybody who walked in for PSA level at a nominal fee of Ksh 1800.00 Now that Kenya has set aside the month of October as the Cancer awareness month, what do the promoters intend to achieve with this campaign? Suddenly, it was dawning on me that my life was under threat from a disease I knew nothing about and had never bothered to read about. At that time my thoughts were on my last two daughters who I had hoped to see through college and become independent adults in my life time. PSA is present in small quantities in the serum of men with healthy prostates but is often elevated in the presence of prostate cancer and in other prostate disorders. For some procedures, contrast agents, such as gadolinium, are used to increase the accuracy of the images. Once these tests are carried out, the doctor will determine if the patient should be on hormonal therapy, radio therapy or chemotherapy. Minimal cancer information, lack of emphasis on early detection and dated treatment options are among the biggest battles for Kenyan’s fight against prostate and other cancers. When I finally did that, he released me to go home but instructed his nurse to give me two new capethers to take with me in case I needed them.
Brendon the speaker for the evening immediately advised that chemotherapy and radiotherapy were not the way to go in my case.
RC Cancer Centers boasts the oldest and largest seed implant programme for prostate cancer in the United States. Men who took a daily dose of the drug enzalutamide started chemotherapy nearly a It is commonly used to treat men with prostate cancer and women who have endometriosis. Saw palmetto is also used for other il saw palmetto conditions including chronic pelvic pain bladder disorders decreased sex drive hair loss and hormone imbalances. Save on ARG's DIM Palmetto Prostate Formula 60Sg and other popular ALLERGY RESEARCH GROUP products. ART significantly improves the probability of hitting targeted tissue and reduces the amount of normal tissue that must be irradiated to ensure that the target is not missed. It is like they are staring death taking their loved one and feel helpless to do anything about it.
It was at that moment when I first called my doctor friend to come to my house as soon as he could. A blood test to measure PSA is considered the most effective current test available for early detection of prostate cancer. This is a Magnetic Resonance Imaging that uses radio and magnetic waves without exposure to X-Rays or any other forms of damaging radiation. Samadi hopes that his hands-on instruction in other countries will give them the foundation they need to achieve expertise in the future. Over the years, it has offered treatment for men in all 50 states in the USA as well as from over 40 countries around the world. The November issue of the Harvard Men’s Health Watch examines the safety and effectiveness of several herbs commonly used to reduce BPH symptoms and offers practical tips that can ease living with this prostate problem. Saw Palmetto berries are especially beneficial to men over the age of 50 seeking to promote and maintain an active lifestyle. Vitamin E supplements contain natural forms if it contains ingredients listed as d-alpha tocopherol, d-alpha tocopheryl acetate, or d-alpha tocopheryl succinate.
Is it the government, doctors that normally deal with cancer cases, hospitals or cancer patients already diagnosed and undergoing treatment?
It is this sense of helplessness that can be devastating unless immediate counseling is offered to the patient and family members to enable them deal with the problem. Sensing that I could be in danger; Prof Bert Obura, himself a physician, got to my house in a record ten minutes.
Kenyans place a large stigma on cancer, and in some areas, those diagnosed are still relying on historic, more natural healing methods. Many international patients know that, unfortunately, their countries cannot offer them the expertise that U.S. On realizing that my PSA had been declining, he chose to continue with the same treatment but added more oral drugs to fortify the hormonal injection I had received in Nairobi the week I left. His service includes laparoscopic and robotic surgery for kidney bladder prostate and testicular cancer patients.
University takes lead role in prostate cancer research by South Wales Echo (Cardiff Wales). African-American men with no family history of prostate cancer should get their baseline PSA and DRE tests at age 40.
The one-letter prefix d denotes the natural form of vitamin Es alpha tocopherol constituent.
They all acted the same way except my eldest daughter who immediately thought of flying me to India for specialized treatment. Due to these factors, most Kenyans receive their diagnosis very late, when it is considered advanced prostate cancer.
Studies indicate that surgeons must perform over 1,600 robotic-assisted laparoscopic prostatectomy (RALP) procedures before achieving acceptable outcomes. His aim was to establish if I had been in honest discussions with my doctor in Nairobi because as he later informed me; treatment of cancer depends very much on the patient as much it depends on the physician in charge. The flowers are yellowish-white about 5 mm across produced in dense prostate causes constipation compound panicles up to 60 cm long. When he looked at them, he confirmed that my case was serious and needed immediate attention. Medical Director of EDAP-TMS commented “This is an extremely important publication as it not only further establishes the safety efficacy and long term durability of HIFU as a prostate cancer treatment it also demonstrates reproducibility. Radiation has been shown to be particularly effective in killing cancer cells and shrinking tumors. Although some normal cells are affected by radiation, most normal cells recover more fully from the effects of radiation than do cancer cells. With Dynamic Targeting® IGRT, clinicians can deliver more tightly focused and precise beams to cancerous tumors.What is Dynamic Targeting® IGRT?Dynamic Targeting IGRT (image-guided radiotherapy) involves using a variety of digital imaging techniques to pinpoint the exact location of a targeted tumor while the patient is in the treatment position, just prior to each daily treatment. They can shift and move slightly between treatments, and even during treatments due to normal physiological processes, such as breathing.
IGRT uses advanced imaging techniques to verify the patient’s exact position and the tumor’s precise location at the moment of treatment. Dynamic Targeting IGRT is a radiotherapy treatment approach that utilizes multiple imaging and motion management techniques for ultra-accurate tumor targeting.Why would I want to be treated with IGRT?Because it enhances radiotherapy treatment precision, IGRT allows physicians to escalate the radiation dose to cancer cells while keeping the dose to surrounding tissues as low as possible. This increases the chances of eradicating the tumor and minimizing treatment side effects.What kind of radiation is used in IGRT?Currently, photons (X-rays) are used to deliver IGRT.
This machine stands approximately nine feet tall, is nearly 15 feet long and can be rotated around the patient with great precision. Operationally, microwave energy, similar to that used in satellite television transmission, is used to accelerate electrons to early the speed of light. As they reach maximum speed they collide with a tungsten target which, in turn, releases photons, or X-rays.Does radiation therapy expose people to radioactive substances?Many people, when they hear the word “radiation,” think immediately of radioactive substances.
However, no radioactive substances are involved in the creation of X-rays or electrons by a medical linear accelerator. When a linear accelerator is switched “on,” radiation is produced and aimed directly at cancer cells. As part of diagnosis, physicians generate three-dimensional diagnostic images (usually CT or MRI) of the patient’s anatomy and use these to specify the dose of radiation each area will receive.
In some cases, treatment planning includes a simulation session to further localize the cancer and finalize the radiation treatment plan.Patients receive their IGRT treatments according to various schedules, usually five days a week for six or seven weeks.
Each treatment takes ten to fifteen minutes.What is the IGRT process like?The IGRT process is similar to a typical radiation treatment, except that it includes an additional imaging step just prior to each daily treatment.
Typically, after conducting a physical exam and a medical history review, the radiation oncologist determines an individualized course of treatment for each patient.Treatment Preparation Most cases require a treatment preparation session. Special molded devices that help the patient maintain the same position every day are sometimes developed at this point.
Colored, semi-permanent ink may be used to mark the patient’s skin, to assist in positioning the patient for treatment by aligning the radiation equipment with the targeted area. A special CT scan in the treatment position is sometimes taken, for use as a reference image later on in the process.
The treatment preparation session might take from thirty minutes to an hour and the CT scan might take an additional 15-30 minutes.Following the CT scan, the radiotherapy treatment planning process usually takes several days. When the plan is complete, the patient is given an appointment to begin radiation treatments.Treatment Delivery The first IGRT treatment session is sometimes longer than subsequent ones so that additional X-ray films and checks can be done. A typical treatment session lasts about 15 minutes.In the treatment room, the radiation therapist uses the marks on the patient’s skin to locate the treatment area.
Sometimes, special molded devices are used to help with rough positioning.The radiation therapist leaves the treatment room and remotely controls a digital On-Board Imager® kV imaging system to fine-tune the patient’s position and move the treatment couch into final position. The On-Board Imager rotates around the patient to take digital images of the targeted area.
These images are then used to guide the final adjustments of the treatment couch.Although the patient is alone in the treatment room, he or she can be seen on a television screen or through a window in the control room. Patients do not see or hear the radiation and usually do not feel anything.TreatmentVarian’s On-Board Imager® kV imaging system gathers images, pinpointing the exact tumor location just prior to treatment. The radiation oncologist works closely with other doctors and also heads a highly trained health care team.
When radiation is used for palliative care, the course of treatment lasts for two to three weeks. For each radiation therapy session, the patient is in the treatment room for about 15 to 30 minutes. These types of schedules, which use small amounts of daily radiation rather than a few large doses, help protect normal body tissues in the treatment area. The total dose of radiation and the number of treatments a patient needs depend on the size and location of the cancer, the type of tumor, the patient’s general health and other factors.What are the effects of treatment?External radiation therapy does not cause a patient’s body to become radioactive.
Even hugging, kissing, or having sexual relations with others poses no risk to them of radiation exposure.Side effects of radiation therapy most often are related to the area that is being treated. Most side effects that occur during radiation therapy, although unpleasant, are not serious and can be controlled with medication or diet.
With Dynamic Targeting IGRT, side effects are minimized, and some patients have no side effects at all.Is IGRT Expensive?Treatment of cancer with radiation can be costly. The exact cost of your radiation therapy will depend on the type and number of treatments you need.Medicare does provide additional reimbursement for the various steps involved in delivering IGRT, whether the treatment occurs in a hospital outpatient environment or in a freestanding outpatient clinic.
A patient is positioned for radiation therapy treatment using Varian’s On-Board Imager® kV imaging system.How is Varian’s Dynamic Targeting IGRT different from other forms of image-guided radiation therapy?arian’s technologies for delivering Dynamic Targeting IGRT include an On-Board Imager for generating high-quality digital images of the targeted area just prior to treatment, as well as a respiratory gating system for coordinating treatment with the patient’s breathing cycle. The On-Board Imager gives clinicians three powerful ways of imaging a patient’s anatomy prior to treatment:In “radiographic” mode, the imager generates two-dimensional X-ray images that show detailed bony anatomy and any implanted fiducial markers, such as gold seeds, that have been placed into the tumor area to facilitate visualization.
The device can take the data from these images and calculate how much the patient should be shifted in three-dimensional space in order to bring the tumor directly into the path of the treatment beam.In “fluoroscopic” mode, the On-Board Imager generates a moving sequence of images that show how the anatomy is moving over time, usually due to the patient’s respiration. By analyzing these images, doctors can determine the optimal window in a patient’s breathing cycle for delivering the treatment.Finally, in “cone-beam CT” mode, the On-Board Imager generates three-dimensional images that show soft-tissue structures (organs such as the prostate, or the tumors directly), and make it possible to check for changes in tumor size or position.
