ABSTRACT=ObjectiveThere are many treatment options for localized prostate cancer, including external beam radiation therapy (EBRT), stereotactic body radiation therapy (SBRT), and prostate brachytherapy (BT). This study aimed to compare the travel burdens of high-dose-rate brachytherapy (HDR-BT) at our BT center and EBRT or SBRT if administered close to home.Materials and methodsThis single-institution retrospective cohort study included 69 patients who had HDR-BT monotherapy for their prostate cancer from August 2017 to December 2022. The travel burden for HDR-BT monotherapy was estimated using Google Maps by measuring the distance from each patient’s home address to our BT center. The total travel burden was calculated by multiplying the number of treatment fractions required for each modality by the roundtrip travel distance between the home and the treatment facility. Treatment toxicity was evaluated using the Expanded Prostate Index Composite for Clinical Practice (EPIC-CP) questionnaire.ResultsThe median age of the 69 patients was 67 years. The mean distance from home to the BT center was 37.4 mi, while the mean distance to the nearest radiation facility was 8.3 mi. The mean total travel distance for HDR-BT was 150 mi, while those for EBRT and SBRT were 463 and 83 mi, respectively. HDR-BT resulted in a mean travel burden reduction of 313 mi compared with EBRT. The EPIC-CP scores indicated minimal posttreatment toxicity, with most patients reporting stable or improved symptoms.ConclusionHDR-BT monotherapy significantly reduces the travel burden compared with EBRT for localized prostate cancer, with minimal treatment-associated toxicity. Increasing the availability of BT centers could further alleviate the travel burden. Alternatively, providing transportation support could improve access to care.
