<b><i>Introduction:</i></b> 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. <b><i>Methods:</i></b> 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. <b><i>Results:</i></b> 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. <b><i>Discussion/Conclusion:</i></b> Salvage radiotherapy after HIFU treatment can be performed safely, thereby providing acceptable recurrence-free survival without severe impact on post-interventional quality of life.
ZusammenfassungWir berichten über einen 28-jährigen Patienten mit akut aufgetretener skrotaler Schwellung. Laborchemisch zeigte sich kein Hinweis auf eine Entzündung und sonographisch waren beide Hoden gut perfundiert. Eine Hodentorsion schien anamnestisch und bei der körperlichen Untersuchung als unwahrscheinlich, daher haben wir uns gegen eine operative Therapie entschieden. Im Verlauf konnten mögliche Differenzialdiagnosen ausgeschlossen und der Verdacht eines akut idiopathischen Skrotalödems (AISE) bestätigt werden. Nach eintägiger stationär-antiphlogistischer Therapie konnte der Patient wieder nach Hause entlassen werden. Das Fallbeispiel zeigt, dass die AISE auch bei nicht-pädiatrischen Patienten auftreten kann und zu vorderst eine Ausschlussdiagnose ist.
