Guided radiation therapy for prostate cancer prevents damage to surrounding organs
October 29, 2007PORTLAND, Ore. - Oregon Health & Science University Cancer Institute researchers have found that highly targeted radiation therapy for prostate cancer can ensure that the majority of persons with this tumor will not have any long-term rectal damage.
A group of 231 study participants received a combination of intensity-modulated radiation and seed marker-based image-guided radiation therapies (IM-IGRT) for prostate cancer then were tracked for 1.4 years. Nearly 98 percent of these participants had no rectal damage, according to Todd Scarbrough, M.D., principal investigator, associate professor, radiation medicine, OHSU School of Medicine; and an OHSU Cancer Institute member. This combination allows for millimeter targeting accuracy of the tumor.
"If these outcomes hold over time and the results can be reproduced by others, then this combination of radiation therapies for prostate cancer will yield some of the lowest toxicity rates of any definitive treatments for prostate cancer. This would be the treatment for prostate cancer. A patient could cruise through treatment with no side effects," explained Scarbrough who also serves as director of the MIMA Cancer Center, Melbourne, Fla.
A poster of this study will be presented Monday, Oct. 28, at the 2007 annual American Society of Therapeutic Radiology and Oncology (ASTRO) meeting in Los Angeles.
Scarbrough explained that the one of the main considerations of radiation oncologists treating prostate cancer is to reduce rectal damage. Previously, 10 percent to 50 percent of men treated for prostate cancer had some level of rectal pain or complaints after radiation.
The image-guided radiation method used placed tiny gold pellets in the subject's prostate prior to treatment and then imaged these markers immediately prior to treatment. Placing of the markers is fast and relatively painless. The heightened accuracy allows for a more precise radiation dose and a more targeted area for treatment of the tumor.
In this study the researchers also found that of the potent men completing sexual satisfaction questionnaires post-treatment, 72 percent reported they had maintained sexual activity. The average age for the study participants was 74. Also, the combination radiation therapy caused no long-term urinary side effects.

Prostate Cancer Current Events and Prostate Cancer News RSSResearchers Identify Role of Gene in Tumor Development, Growth and Progression
Virginia Commonwealth University Massey Cancer Center and VCU Institute of Molecular Medicine researchers have identified a gene that may play a pivotal role in two processes that are essential for tumor development, growth and progression to metastasis.
Common pain relief medication may encourage cancer growth
Although morphine has been the gold-standard treatment for postoperative and chronic cancer pain for two centuries, a growing body of evidence is showing that opiate-based painkillers can stimulate the growth and spread of cancer cells.
Young athletes need dual screening tests for heart defects, study suggests
To best detect early signs of life-threatening heart defects in young athletes, screening programs should include both popular diagnostic tests, not just one of them, according to new research from heart experts at Johns Hopkins.
Routine evaluation of prostate size not as effective in cancer screening, Mayo study finds
New Mayo Clinic research studied the association between prostate-specific antigen (PSA) levels and prostate size and found that routine annual evaluation of prostate growth is not necessarily a predictor for the development of prostate cancer.
Carnegie Mellon researchers link health-care debate to risk of dying in US and Europe
The current health care debate in the United States is complicated. Trade-offs between heath care expenditures, lifestyle choices and life expectancy have been suggested but seldom clearly demonstrated.
New finding suggests prostate biopsy is not always necessary
Researchers at Wake Forest University School of Medicine and the University of Wisconsin-Madison have discovered that some elevated prostate-specific antigen (PSA) levels in men may be caused by a hormone normally occurring in the body, and are not necessarily a predictor of the need for a prostate biopsy.
Does prostate-specific antigen velocity help in early detection prostate cancer?
The November issue of European Urology, the official journal of the European Association of Urology, features an article focussing on prostate specific antigen (PSA) velocity and early cancer detection. It has been suggested that changes in PSA over time aid prostate cancer detection.
New Synthetic Molecules Trigger Immune Response to HIV and Prostate Cancer
Researchers at Yale University have developed synthetic molecules capable of enhancing the body's immune response to HIV and HIV-infected cells, as well as to prostate cancer cells. Their findings, published online in the Journal of the American Chemical Society, could lead to novel therapeutic approaches for these diseases.
Chemo-radiation before prostate removal may prevent cancer recurrence
Researchers in the Oregon Health & Science University Knight Cancer Institute and the Portland Veterans Affairs Medical Center have found a combination of radiation therapy and chemotherapy given before prostate removal is safe and may have the potential to reduce cancer recurrence and improve patient survival.
Blood vessels might predict prostate cancer behavior
A diagnosis of prostate cancer raises the question for patients and their physicians as to how the tumor will behave. Will it grow quickly and aggressively and require continuous treatment, or slowly, allowing therapy and its risks to be safely delayed?
