PHASE2

Brief Summary

The goal of this clinical study is to evaluate the toxicity and efficacy of re-irradiation using focal stereotactic body radiotherapy (SBRT) in patients with local recurrence of prostate cancer after ...

Detailed Description

The diagnosis of local recurrence after radiotherapy in patients with prostate cancer is a serious clinical problem. Interventional salvage treatment in the previously irradiated area is difficult wit...

Eligibility Criteria

Inclusion

  • Local recurrence of prostate cancer after definitive radiotherapy
  • biopsy proven or/and
  • Consistent MRI and PET-PSMA results and PSA growth dynamics
  • Time since primary radiotherapy - at least 2 years
  • Good performance status (ZUBROD 0-1)
  • If the results of the MRI and PET PSMA are inconsistent, and if there is no technical possibility of performing an MRI biopsy, the treatment is acceptable, but repeated imaging (PET or MRI) should be performed to assess the dynamics of the recurrence.

Exclusion

  • Polymetastatic dissemination in distant or regional lymph nodes (N1, M1) or oligometastatic dissemination, but not eligible for local forms of metastasis directed therapy (MDT)
  • Tumour volume (GTV) \> 14 cc
  • Poor tolerability of primary radiotherapy (≥G3 toxicity) or persistent late toxicity ≥G2 interfering with re-irradiation
  • Severe dysuria before repeated SBRT (e.g., IPSS ≥19)
  • Diseases of the distal part of the rectum or anal canal that may affect SBRT tolerance (e.g., anal fissure)
  • Previous prostate brachytherapy
  • Substantial risk for further urologic interventions (e.g., TURB/TURP)
