Study Details

Study Description

Brief Summary

STereotactic sAlvage Radiotherapy for macroscopic prostate bed Recurrence after prostatectomy (STARR trial) is a prospective observational study aimed to assess outcome after Stereotactic salvage radiotherapy (SSRT) for macroscopic prostate bed recurrence after radical prostatectomy.

Condition or Disease Intervention/Treatment Phase
  • Other: Stereotactic salvage radiotherapy for macroscopic prostate bed relapse

Detailed Description

This is a prospective observational multicenter study including patients affected by patients with macroscopic recurrence within prostate bed after RP detected with Choline or PSMA CT-PET and confirmed with pelvic MRI (except for cases in which MRI is contraindicated). Patients will be treated with SSRT on macroscopic prostate bed recurrence for a total dose of from 35 in 5 fractions. Planned size of the overall study population is 90 patients. The study will include a screening phase and a treatment phase. The screening phase allows for assessment of subject eligibility, demographics, PSA, comorbidities and current drug therapies up to 45 days prior to randomization.

The treatment phase consists of SSRT administered on prostate bed macroscopic recurrence. Different techniques will be allowed provided that treatment respects doses and fractionation indicated per-protocol (35 Gy in 5 fractions) and that dose constraints to organs at risk (OAR) reported in this document are observed. The total planned duration of the study is 40 months, consisting in 16 months enrollment period, during which patients will perform the screening and and later phase of 24 months in which patients will continue to be submitted to periodic checks every 3 months.

Outcome Measures

Primary Outcome Measures

  1. Biochemical relapse free survival (BRFS) [2 year]

    Primary endpoint of the study is BRFS after treatment, biochemical relapse is defined as a PSA increase above 0.2 ng/ml for patients with a PSA nadir < 0.2 ng/ml or 2 consecutive PSA increases > 25% if compared to nadir in patients with a PSA nadir > 0.2 ng/ml.

Secondary Outcome Measures

  1. Rate of patients with complete response [at 2 years after treatment]

    Complete response is defined as PSA nadir <0.2 ng/ml

Eligibility Criteria

Criteria

Ages Eligible for Study:
18 Years and Older
Sexes Eligible for Study:
Male
Accepts Healthy Volunteers:
No
Inclusion Criteria:
  • Patients affected by biochemical recurrence after radical prostatectomy for prostate cancer (defined as a PSA increase > 0.2 ng/ml)

  • Presence of macroscopic recurrence in prostate bed, determined with either Choline or PSMA PET imaging and confirmed through MRI (except for cases in which MRI is contraindicated)

  • Absence of distant and/or regional sites of disease outside prostate bed

  • Patients free from Androgen deprivation therapy (ADT) (Adjuvant ADT after radical prostatectomy for pN+ patients is allowed if > 12 months from biochemical recurrence)

Exclusion Criteria:
  • Presence of distant and/or regional sites of disease outside prostate bed

  • Patient undergoing ADT or withdrawal of adjuvant ADT within12 months from biochemical recurrence

  • Absence of disease detection from one of the two imaging modalities used (Choline or PSMA Pet and MRI must be positive- except for cases in which MRI is contraindicated)

  • Any condition for which, in the opinion of the treating physician, SSRT would be contraindicated for the patient (i.e peristence of moderate/severe urinary distress after prostatectomy, post-surgical complications etc)
