Summary
This review summarizes male breast cancer epidemiology, diagnosis, and treatment. Advances in female breast cancer research can inform male patient care and improve survival rates through education and data collection.
Area of Science:
- Oncology
- Epidemiology
- Genetics
Background:
- Male breast cancer is rare, with unique risk factors including advanced age, family history, and hormonal imbalances like Klinefelter's syndrome.
- Presentation of advanced male breast cancer often includes pain, bloody discharge, and skin ulceration.
- Gynecomastia is a complex factor, used for both histological findings and physical examination in male breast conditions.
Purpose of the Study:
- To comprehensively review the epidemiology, clinical presentation, diagnostic approaches, molecular genetics, treatment strategies, and prognosis of male breast cancer.
- To consolidate current knowledge on male breast cancer, drawing parallels with advancements in female breast cancer research.
- To identify key factors influencing the prognosis and potential areas for improved patient outcomes.
Main Methods:
- A systematic literature review of English and French articles from Medline (1966-2001) using keywords 'male breast cancer'.
- Inclusion criteria focused on institutional experiences, comparative diagnostic/treatment modalities, and epidemiological or general reviews.
- Fifty articles were selected from an initial search of 198 for detailed analysis.
Main Results:
- Identified risk factors include advanced age, family history, Jewish origin, black race, hormonal exposure (Klinefelter's syndrome), irradiation, alcohol, obesity, and childlessness.
- Infiltrating ductal adenocarcinoma is the most common histology. Diagnostic imaging like mammography has limitations, and fine-needle aspiration may overestimate malignancy.
- Treatment involves modified radical mastectomy, adjuvant chemotherapy (CMF or FAC regimens), and potentially tamoxifen. Radiotherapy offers no apparent benefit. Prognostic factors include tumor size, lymphatic invasion, and axillary node status.
Conclusions:
- Given the low incidence, progress in male breast cancer management relies on applying knowledge from female breast cancer research.
- Adjuvant chemotherapy combined with postoperative tamoxifen may improve survival rates for male breast cancer patients.
- Public education targeting high-risk men and rigorous data collection are crucial for characterizing etiology and improving early detection and outcomes.
