Recruiting
Conditions
Prostate Cancer
Interventions
Radiation: Daily Adaptive RadioTherapy
Registration Number
NCT05884632
Lead Sponsor
IRCCS Sacro Cuore Don Calabria di Negrar
Brief Summary

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.

Primary Outcome Measures
NameTimeMethod
Acute gastrointestinal toxicity90 days from the RT treatment

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.

Secondary Outcome Measures
NameTimeMethod
Time to biochemical failure24 months

Time between salvage RT and biochemical failure

Local in-field relapse24 months

Local in-field relapse evaluated with PET-CT or RM

QLQ-C30At screening, 2nd and 4th week during RT, at 3, 6, 12, and 24 months

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

Biochemical failure24 months

PSA raise after RT from nadir

Acute genitourinary toxicity90 days from the RT treatment.

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.

Late toxicityFrom 90 days after the RT treatment until 24 months

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.

Metastases-free survival24 months

Metastases-free survival evaluated with PSMA PET-TC in case of PSA raise
