- Abstract
Introduction: The aim of this study was to evaluate toxicity, oncological and functional outcome, and quality of life after salvage radiotherapy for recurrent prostate cancer after high-intensity focused ultrasound (HIFU) therapy. Methods: A total of 13 patients undergoing salvage radiotherapy for biopsy-proven prostate cancer recurrence after HIFU therapy were included and followed up every 3 months. Oncological outcome (by PSA measurements), toxicity (according to CTCAE criteria), and functional outcome were evaluated. Quality of life was assessed by standardized questionnaires (QLQ-C30 and QLQ-PR25) at baseline, 3 months, and 12 months after salvage treatment. Results: Median age of patients was 80 years (interquartile range [IQR] 75–82). Patients underwent normofractionated salvage radiotherapy with median 73.6 Gy. PSA nadir was reached at 6 months and was 0.2 ng/mL. Median follow-up was 76 months (IQR 55–96). Biochemical recurrence occurred in 3 patients (23.1%) at a median of 36.4 months. No gastrointestinal (GI) or genitourinary (GU) toxicity ≥ grade 3 was noted during follow-up. Early and late grade II GI toxicity occurred in 1 patient (7.7%), respectively. GU toxicity grade II was noted in up to 53.8% at 3 months and 61.5% at 12 months. In terms of health-related quality of life, there was no statistically significant difference at 3 and 12 months compared to the baseline. Only differences were seen in sexual functioning (3 and 12 months) and in diarrhea (3 months), affecting patients' wellbeing. Discussion/Conclusion: Salvage radiotherapy after HIFU treatment can be performed safely, thereby providing acceptable recurrence-free survival without severe impact on post-interventional quality of life.
