SBRT in 4 Fractions for Prostate Cancer

March 11, 2019 updated by: Michele Tedeschi, Istituto Clinico Humanitas

Phase I-II Study of High Dose SBRT in 4 Fractions for Intermediate Risk Prostate Cancer

This is a prospective multicentric phase-I-II pilot feasibility study. The main objective is to study early and late side effects of hypofractionated accelerated RT for prostate cancer with FFF (Free Flattened Filter) beam. The schedule will be [ 4 x 9.5 Gy = 38 Gy ] delivered in 5 alternative days.
