Prostate cancer patients and their doctors may want to think twice about the best timing for chemotherapy or radiation therapy in conjunction with a common nonsurgical treatment, based on international research findings led by UT Southwestern Medical Center investigators.
High dose of radiation may not be beneficial on low-risk prostate cancer, according to the experts.
At Thomas Jefferson University’s Cancer Center in Philadelphia, there was a research about the radiation and prostate cancer. The study can be found in American Journal of Clinical Oncology recently.
It was often thought that if the highest dose of radiation a body can tolerate will be the best way to kill the prostate cancer but the result somewhat turns to different, said Dr. Robert Den.
The results of the research shows that it is not always good to treat low-risk prostate cancer patient this way.
Researcher have viewed 12 studies on this topic in which was included 6,800 patients. The result of this treatments is to result to drop in prostate specific antigen (PSA).
The higher doses of radiation doesn’t always lower the rates of prostate cancer.
It is important to check our assumptions, because the overall study tells us that the PSA test is not much benefit for the patients as the researcher expected, said Adam Dicker.
This study needs further clinical trials and also an interpretation of current and previous studies.
