BACKGROUND/AIM: To evaluate the treatment outcomes, toxicity and health-related quality of life (HRQOL) in prostate cancer (PCa) patients who underwent single-fraction high-dose-rate brachytherapy (single-fraction HDR-BT) with external beam radiotherapy (EBRT).
MATERIALS AND METHODS: From April 2014 to October 2017, treatment outcomes and toxicity of 85 patients who underwent single-fraction HDR-BT of 13 Gy, followed by 46 Gy EBRT in 23 fractions, were examined. HRQOL of 53 patients was evaluated using the Expanded Prostate Cancer Index Composite (EPIC), International Prostate Symptom Score (IPSS)/QOL index, International Index of Erectile Function 5 (IIEF-5), and 36-Item Short Form Survey (SF-36) scores through one year.
RESULTS: The median follow-up period was 28.8 months. Only three patients had biochemical recurrence. Toxicities included less than grade 3 lower urinary tract symptoms and grade 1 diarrhea. Urethral stricture, a problem related to late toxicity in conventional HDR-BT, was not observed. The urinary and bowel functions in EPIC scores significantly worsened until three or six months after treatment, respectively.
CONCLUSION: Single-fraction HDR-BT with EBRT showed promising biochemical control, tolerant toxicities, and preservation of HRQOL, and can be efficiently performed in a shorter time than conventional HDR-BT.
