a study on Prostate Cancer
This is a phase I feasibility study to evaluate the feasibility of hypofractionated whole pelvis radiotherapy in 35 patients with biopsy-proven intermediate- to high-risk prostate cancer as defined by NCCN risk criteria. Patients will have>15% risk of lymph node involvement as defined by the Roach equation 2/3(PSA)+10(Gleason Score-6). Day 0 of the study will be defined as the time of first LHRH/agonist/antagonist injection of hormone therapy. Radiation therapy should begin within 8 weeks (+/- 1 week) after the date of the first LHRH agonist/antagonist injection. Patients will be followed at 6 weeks and then every 3 months for the first 24 months after completion of radiotherapy in a similar schedule to usual standard of care. A history and physical, PSA, testosterone and EPIC-26 questionnaire will be collected at each visit. Any toxicity according to CTCAE v. 4.0 criteria will be documented. An interim analysis for evaluating acute toxicity (≤90 days) will be performed after the first follow-up visit of the20th patient enrolled on protocol. The trial will be terminated if>30% acute grade 2 or>5% grade 3 or greater toxicity is observed as a result of radiation treatment by CTCAE v. 4.0 criteria. Grade 2 toxicity is defined as a minimal, local or noninvasive intervention. Grade 3 toxicity is defined as a severe or medically significant but not immediately life-threatening event requiring hospitalization or prolongation of hospitalization. Previous studies have demonstrated approximately 30% and 5% incidence of Grade 2 and Grade 3 or greater toxicity, respectively, with conventionally fractionated radiotherapy followed by brachytherapy.
