Significant impact of biochemical recurrence on overall mortality in patients with high‐risk prostate cancer after carbon‐ion radiotherapy combined with androgen deprivation therapy

摘要

BACKGROUNDWhether biochemical recurrence (BR) is a significant predictive factor of mortality after definitive radiation therapy for prostate cancer remains unknown. The aim of the current study was to investigate the relation between BR and overall mortality (OAM) in high‐risk prostate cancer patients who were treated with carbon‐ion radiotherapy (CIRT) and had long‐term follow‐up in 2 prospective trials.
