There are radiobiological rationales supporting hypofractionated radiotherapy for prostate cancer. The recent advancements in treatment planning and delivery allow sophisticated radiation treatments to take advantage of the differences in radiobiology of prostate cancer and the surrounding normal tissues. The preliminary results from clinical studies indicate that abbreviated fractionation programs can result in successful treatment of localized prostate cancer without escalation of late toxicity.

e16147 Background: Prostate cancer is the most common male malignancy, and there is no one standard treatment modality. One treatment option is the combination of external beam radiotherapy and permanent transperineal brachytherapy seed implant Methods: Retrospective review of prostate cancer and side effect outcomes at a single institution in the community setting. All patients were treated with a combination of low dose rate transperineal brachytherapy seed placement and external beam radiation. Results: A total of 897 patients were analyzed, 781 had a minimum follow-up of one year. Median pre-treatment PSA was 8.1 (range 0.3 to 106) and the median Gleason score was 6. With a median follow-up of 3.6 years, 33 (3.4 %) patients had biochemical failure based on the phoenix definition of Nadir + 2. Not including impotence, acute toxicity greater than or equal to Grade 2 was seen in 115 patients (102 GU and 13 GI) and 193 patients had late toxicity greater than or equal to Grade 2 (155 GU and 38 GI). 563 patients received hormone therapy prior to or concurrent with the radiation. Conclusions: This is the largest series reporting on the outcome of combination brachytherpay implant and external beam radiation in the treatment of prostate cancer. Combination treatment using brachytherapy and external beam radiation is well tolerated, with a low rate of biochemical failure and should be considered one of the treatment options for prostate cancer.
