Cancer-specific mortality of high-risk prostate cancer after carbon-ion radiotherapy plus long-term androgen deprivation therapy.

ABSTRACT: The treatment outcomes of patients with high-risk localized prostate cancer (PC) after carbon-ion radiotherapy (CIRT) combined with long-term androgen deprivation therapy (LTADT) were analyzed, and compared with those of other treatment modalities, focusing on PC-specific mortality (PCSM). A total of 1247 patients were enrolled in three phase II clinical trials of fixed-dose CIRT between 2000 and 2013. Excluding patients with T4 disease, 608 patients with high-risk or very-high-risk PC, according to the National Comprehensive Cancer Network classification system, who received CIRT with LTADT were evaluated. The median follow-up time was 88.4 months, and the 5-/10-year PCSM rates were 1.5%/4.3%, respectively. T3b disease, Gleason score of 9-10 and percentage of positive biopsy cores >75% we
