Comparing Long-term Biochemical Control of Prostate Cancer after Standard or Hyperfractionated Radiation Therapy: Evidence of a Different Behavior between Low-intermediate and High Risk Patients

To report the long-term biochemical relapse free survival (bRFS) of a non-randomized trial comparing standard (SFX, 2.0Gy/day) and hyperfractionated (HFX, 1.2Gy twice daily) schedules and to analyze the implications for the alpha/beta (α/β) of prostate carcinoma (PCa). Between 1993 and 2003, 370 pts entered the study. Three hundred thirty pts are evaluable for this analysis (179 SFX, 151 HFX). Pre-treatment and treatment variables were similar...
