    AbstractTo analyze and compare the clinicopathological characteristics of male breast cancer (MBC) among Chinese patients and those from East Asia and other regions. Clinicopathological data from 3 kinds of data sources, including 31 MBC patients in Jiangsu Provincial Hospital (JPH) from 2014 to 2021 in China, 20 literature data on East Asian MBC patients from 2014 to 2021, and 3102 MBC patients registered in the surveillance, epidemiology, and end results (SEER) database from 2014 to 2019, were collected and retrospectively analyzed. The average ages of first-diagnosis MBC patients in JPH and East Asian patients were 59.7 and 62.3 years old, respectively, which were younger than those of SEER patients (66.5 years old). Between East Asian and SEER patients, the status or rates of main breast cancer type, estrogen receptor, progesterone receptor, human epidermal growth factor receptor 2, breast subtype, and TNM stage were relatively close, and their differences were not statistically significant (P > .05). Differences were observed in chemotherapy, surgery, pathological grade, and lymph node positivity (P < .01). Furthermore, no statistically significant difference was observed between the JPH and East Asian patients (all P > .05). In JPH and SEER, linear regression relationships were observed between the lymph node positivity rate, tumor size, and histological grade. JPH and East Asian MBC patients were younger than SEER patients. Between East Asian and SEER patients, the status of the main breast cancer type, estrogen receptor, progesterone receptor, human epidermal growth factor receptor 2, breast subtype, and TNM stage were similar, but there were differences in chemotherapy, surgery, pathological grade, and lymph node positivity. The findings of this study should prove to be helpful to deepen our understanding of East Asian MBC.Copyright © 2023 the Author(s). Published by Wolters Kluwer Health, Inc.
