A novel imaging approach for prostate cancer is tested in new clinical trial
Using a cutting edge approach to treat prostate tumors that have returned after a radiation treatment, physicians believe they can target tumors with pinpoint accuracy using high quality prostate MRI and an investigational imaging technique to guide focal, ablative radiation treatment, while sparing surrounding organs from possible injury. The image shows the dose plan in color wash treating the tumor but not the entire prostate (shown in blue) while sparing the bladder (yellow) and rectum (brown).

Generally, prostate cancer patients who have failed standard radiation therapy have the options of surgery, radioactive seed implantation or cryoablation. These treatments are invasive and can have serious side effects. Deborah Citrin, M.D., of the Radiation Oncology Branch is leading a study of stereotactic body radiation therapy (SBRT) to treat prostate cancer that has recurred locally after standard radiation therapy. With SBRT, specially designed imaging techniques identify prostate cancer and pinpoint the tumor’s exact location. This enables physicians to deliver a high dose of radiation directly to the tumor within the prostate gland. Thus, SBRT can deliver escalating doses of potent radiation in a shorter course of treatment than standard radiation therapy. According to Dr. Citrin, “The use of a novel imaging study to minimize the exposure to uninvolved tissue may enhance our ability to cure these recurrent tumors and reduce side effects for our patients - an important goal for those suffering from recurrent prostate cancer.” SBRT has shown promising results in previous studies. The goal of this study is to define the best dose of SBRT for patients whose prostate cancer has recurred after standard radiotherapy.
