Patients and methods Cohorts A and B included 161 and 182 cases, respectively, who underwent surgery before (2000-2007) and after (2008-2015) the introduction of adjuvant trastuzumab. Results The rates of relapse-free and distant metastasis-free survival were significantly better in cohort B than in cohort A. The risk factors of distant recurrence found in cohort A, such as the presence of lymph node metastasis, lymphatic invasion, and a low histological grade, did not increase the risk in cohort B. Conclusion Many risk factors seemed to have been negated by adjuvant trastuzumab administration. Therefore, further escalation of adjuvant treatment should be carefully considered.Background/aim Recent evidence has shown that African American men with prostate cancer may have more radiosensitive disease with greater overall survival (OS) with radiotherapy compared to Caucasian men. We compared OS in African American and Caucasian men receiving radiotherapy utilizing the National Cancer Database. Patients and methods African American or Caucasian men with N0M0 prostate adenocarcinoma diagnosed between 2004 and 2013 were selected and grouped into favorable and unfavorable risk based on clinical T-stage, clinical Gleason score, and prostate-specific antigen. Patients with favorable risk received brachytherapy or dose-escalated external beam radiation (EBRT); those with unfavorable risk received EBRT plus anti-androgen therapy with/without brachytherapy. African American and Caucasian men in each subgroup were propensity score-matched and analyzed for survival. Sensitivity analysis used treatment-race and age-race intera
