This is a monoinstitutional prospective pilot study, aiming to evaluate treatment-related toxicity of an hypofractionated postoperative salvage radiotherapy with daily-adaptive modality in patients affected by prostate cancer biochemical recurrence. Patients will be treated with postoperative hypofractionated salvage radiotherapy with a dose of 59 Gy in 20 fractions with daily-adaptive modality. Considering the consolidate role and clinical outcome of postoperative hypofractionated radiotherapy with elevate level of evidence (8-10), the study will not be controlled, but compared with literature data.

RECRUITINGAcute gastrointestinal toxicity
Will be evaluated by physician-reported outcome according to the Common Terminology Criteria for Adverse Events (CTCAE version 5.0) and by patient-reported outcome according to the EPIC questionnaire. More specifically, acute toxicity will be defined as any gastrointestinal event occurred within 90 days from the RT treatment with grade ≥G2.
Time frame: 90 days from the RT treatment
Acute genitourinary toxicity
Will be evaluated by physician-reported outcome according to the Common Terminology Criteria for Adverse Events (CTCAE version 5.0), and by patient-reported outcome according to the EPIC questionnaire. More specifically, acute toxicity will be defined as any genitourinary event occurred within 90 days from the RT treatment.
Time frame: 90 days from the RT treatment.
Late toxicity
Will be evaluated by physician-reported outcome according to the Common Terminology Criteria for Adverse Events (CTCAE version 5.0), and by patient-reported outcome according to the EPIC questionnaire. More specifically, late toxicity will be defined as any event (genitourinary and gastrointestinal) occurred from 90 days after the RT treatment.
Time frame: From 90 days after the RT treatment until 24 months
QLQ-C30
Patient-reported outcomes will be assessed via the EORTC global (QLQ-C30) questionnaires at screening, 2nd and 4th week during RT, at 3, 6, 12, and 24 months
Time frame: At screening, 2nd and 4th week during RT, at 3, 6, 12, and 24 months
Biochemical failure
PSA raise after RT from nadir
Time frame: 24 months
Time to biochemical failure
Time between salvage RT and biochemical failure
Time frame: 24 months
Local in-field relapse
Local in-field relapse evaluated with PET-CT or RM
Time frame: 24 months
Metastases-free survival
Metastases-free survival evaluated with PSMA PET-TC in case of PSA raise
Time frame: 24 months
