Male breast cancer (MBC), though rare, presents significant challenges to men's health. A recent comprehensive study utilizing data from the Surveillance, Epidemiology, and End Results (SEER) database highlights alarming trends in the incidence of MBC and offers new insights for predicting survival outcomes in patients diagnosed with this rare disease.
MBC, accounting for only 1% of all breast cancer cases, is often diagnosed at advanced stages due to the absence of male-specific screening programs. The study analyzed MBC incidence data spanning from 1975 to 2019, utilizing the Age-Period-Cohort (APC) model to assess trends related to age and birth cohort effects. The research found the incidence of MBC increases significantly with age and noted important correlations with certain prognostic factors.
According to the findings, men aged 80 to 84 years have approximately 27 times higher odds of being diagnosed with MBC compared to those aged 35 to 39. The study included over 2,000 patients and identified several factors significantly associated with shorter survival, including older age, negative estrogen and progesterone receptor status, and advanced cancer stages.
Notably, the study developed a competing risk nomogram to accurately predict breast cancer-specific survival (BCSS) for MBC patients, showing superior performance when compared to conventional prognostic models such as the AJCC staging system. The competing risk model accurately reflects real-world conditions, offering clinicians improved tools for decision-making.
"The high incidence and poor prognosis of MBC in the elderly population emphasizes the need for improved screening and early diagnosis in high-risk groups," the study authors stated. This points to the necessity for heightened awareness and targeted interventions to address the unique challenges posed by MBC, particularly as the population ages.
The findings cover not only the trends but also the clinical significance of MBC, indicating the necessity for unique care strategies different from those traditionally employed for female breast cancer treatment. Foremost, the study advocates for early diagnosis and the establishment of male-specific screening protocols due to the obviously increasing risk associated with advancing age.
"Our competing risk model, compared to the Cox model, more accurately reflects real-world conditions," said the authors, indicating the practical applications of this research. The nomogram has demonstrated significant accuracy and clinical utility, validating its ability to assist clinicians predict individual survival outcomes.
Future research is necessary to refine these predictive tools and explore specific therapeutic pathways, particularly considering the distinct biological characteristics and clinical presentation of MBC compared to female breast cancer. Given the study's conclusions, it is evident the time has come to invest efforts to increase screening rates and improve the care continuum for male breast cancer patients.
Overall, the study not only sheds light on long-term trends but also emphasizes the urgent need for increased attention and resource allocation to address male breast cancer's unique challenges.
