Radiotherapy and Male Breast Cancer

Abstract

The primary surgical procedure did not ultimately influence OS or CSS in this population-based registry of males with breast cancer. A statistically nonsignificant improvement with postoperative RT was observed in men with lymph node involvement, larger tumor size, or higher stage. When controlled for age, stage, and grade in multivariate analysis, postoperative RT predicted for improved OS but not CSS. These data suggest a beneficial effect of RT in the postoperative setting. A prospective study is necessary to further elucidate appropriate treatment strategies for men with breast cancer.
