Phase II Trial of SBRT + or - IMRT in Treatment of Patients With Clinically Confined Prostate Adenocarcinoma

9. januar 2020 opdateret af: GenesisCare USA

A Phase II Trial of Stereotactic Body Radiation Therapy (SBRT) With or Without Intensity Modulated Radiation Therapy (IMRT) in the Treatment of Patients With Clinically Confined Prostate Adenocarcinoma

Patients with locally confined prostate adenocarcinoma (clinical stage T1c - T2bN0M0, Gleason score 7, PSA 20 ng/ml) are assigned to one of two treatment arms. Low risk patients (T1c-T2a and PSA <10 ng/ml and Gleason Score 6 or less) will receive 5 fractions of 8.0 Gy for a total of 40 Gy. Intermediate risk patients (T2b or PSA >10 ng/ml orGleason Score 7) will receive 1.8 Gy of IMRT for 25 fractions over 5 weeks for a total of 45 Gy. They will then receive a boost consisting of 4, 5.5 Gy fractions after IMRT for a total of 22 Gy.
