Serial SBRT Potentially Beneficial in Oligometastatic Prostate Cancer - Renal and Urology News
Serial stereotactic body radiation therapy (SBRT) directed by positron emission tomography (PET) using novel radiotracers may offer clinical benefits in patients with oligometastatic prostate cancer, according to a recent retrospective study. The study's findings suggest that a second course of SBRT for men with recurrent oligometastatic prostate cancer following an initial course of SBRT is an important therapeutic strategy to consider, Daniel H. Kwon, MD, of the University of California, San Francisco, and colleagues reported in Urologic Oncology . The study included 25 men with 1-5 prostate cancer metastases detected on PSMA (prostate-specific membrane antigen) or fluciclovine PET and who underwent 2 consecutive courses of SBRT. At the time of the second SBRT course, PSMA and fluciclovine PET detected oligorecurrent disease in 17 (68%) and 8 (32%) patients, respectively. Of the 25 patients, 15 (60%) had castration-sensitive disease and 10 (40%) had castrat...
