SBRT in 4 Fractions for 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.

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, corresponding to an NTD2 between 95 and 119 Gy for an α/β estimate between 3 and 1.5 Gy.

Primary outcomes

  1. Toxicity assessment of 4 fractions SBRT in selected intermediate risk prostate cancer patients.

    Time frame: up to 5 years

    Toxicity assessment: The presence and grading (CTAE v3/ EORTC-RTOG) of adverse events will be recorded.

  2. Tumour response to local radiation therapy by assessing freedom from biochemical failure.

    Time frame: up to 5 years

    Tumour response is evaluated on ASTRO DEFINITION of PSA relapse (+2 from Nadir of PSA).
