“…With regard to MBC pathological differences in the different ethnic groups, Parise reported that black men with both low and high levels of concomitant disease had an increased risk of mortality when compared with white men with breast cancer. [32] And, Ellington et al pointed out that relative survival 1 year after breast cancer diagnosis was lower among black males than it was among White and Hispanic males [33] ; and a larger proportion of cases in Black males were diagnosed at distant stage than those in White and Hispanic males.…”

To 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.

Background As a rare disease, male breast cancer (MBC) is of increasing concern in China. Whether health inequalities of disease burden and healthcare utilization exist by ethnicity in male breast cancer remains unclear. We aim to measure disease burden and healthcare utilization by ethnicity among male breast cancer patients in China. Methods A retrospective cohort study was established during 2012–2021 based on Inner Mongolia Regional Health Information Platform. Disease burden including incidence, 5-year prevalence, mortality, survival rate, and medical cost were analyzed. Results Among 630 participants (mean [SD] age, 59.4 [13.1] years), age-standardized rates of incidence were 1.2 (95% CI: 0.4–2.1) per 100000. All-cause mortality was 50.8 per 1000 person-years (95% CI: 42.4–60.4) but breast cancer-specific mortality was 5.5 per 1000 person-years (95% CI: 3.0-9.3). Regarding ethnicity, Mongolian had a higher age-standardized 5-year prevalence rate than Han (3.2[95% CI: 2.5-4.0] vs 2.3[95% CI: 1.7-3.0], P = 0.016), but no significant differences existed in incidence rates, survival rates, and risk of all-cause and breast cancer-specific mortality. Patients residing in areas of lower GDP level were associated with increased breast-cancer specific mortality (HR, 22.5, [95% CI: 1.6–325.0]; P = 0.022). Conclusions This study revealed a moderate disease burden and relatively lower healthcare utilization for male breast cancer in Inner Mongolia, China. No significant ethnic disparities existed in disease burden and healthcare utilization. However, we still demanded for increasing attention to male breast cancer due to the crucial influence of economic factors on potential ethnic disparities.
