Clinicopathologic Features and Prognoses of Male Patients With Breast Cancer.

Abstract

Breast cancer is rare in men and is managed using strategies similar to those for breast cancer in women. This study retrospectively analyzed the clinicopathological features, treatment, and survival of male breast cancer (MBC). A total of 66 patients with MBC admitted into Xijing Hospital from August 2006 to March 2024 were reviewed. Data were collected from patients' hospital records and breast cancer database of Xijing Hospital. The incidence of MBC tended to increase from 2018, with affected individuals being older than those with female breast cancer (FBC). The most common histological type of MBC was invasive carcinoma, with positive hormone receptor status. A total of 62 (93.9%) patients with MBC underwent modified radical mastectomy. Chemotherapy was administered to 39 (59.1%) patients, while endocrine therapy was received by 14 patients (21.2%) and radiotherapy by nine patients (13.6%). Survival analysis indicated that the median overall survival (OS) of patients with MBC was 46.7 months (0.9-184.8 months). As of the latest data, 58 patients (87.9%) with MBC are alive. Factors significantly associated with survival included age (χ² = 3.856, p = .050), estrogen receptor (χ² = 10.427, p = .005), molecular types (χ² = 10.641, p = .031), P63 (χ² = 2.631, p < .001), and endocrine therapy (χ² = 31.167, p < .001). These findings provide valuable insights into MBC within the Chinese population and serve as a reference for the standard treatment of MBC.
