Twice High dose external beam Radiotherapy by Image-guided tomotherapy for organ-confined Prostate cancer treatment emulating HDR brachytherapy:~Feasibility trial of twice high dose radiotherapy using Tomotherapy in patients with organ confined Prostate Cancer histologically proven. The study involves 2 steps:~A) Assessment of safety as proportion of patients with acute ≥G3 Genito-urinary (GU) and Gastro-intestinal (GI) side effects on the first 16 enrolled patients; B) evaluation of primary and secondary objectives on overall patients. Thirty-one patients will be enrolled, with histologically confirmed very low , low and intermediate risk prostate cancer following the National Comprehensive Cancer Network (NCCN) risk categories guidelines. Patient should not be eligible to prostatectomy or patient's should refuse to undergo surgery.~Prescription dose to the target: 20-23 Gy in 2 fractions on the whole prostate gland +/- seminal vesicles and 24-27 Gy in 2 fractions as simultaneous integrated boost (SIB) on the dominant intraprostatic lesion (DIL) 2 weeks in all.
