Conditions:   Prostate Adenocarcinoma;   Radiotherapy; Complications;   TomotherapyIntervention:   Radiation: tomotherapySponsor:   Istituto Scientifico Romagnolo per lo Studio e la cura dei TumoriNot yet recruiting

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.

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.
