RESUMO

Introduction: Carcinoma of the male breast is a rare malignancy. Little is known about the disease and few research studies have been conducted on it. Approximately 1500 new cases of male breast cancer are diagnosed per year in the United States. It is estimated that for every one hundred new cases of female breast cancer, there is one case of male breast cancer. The tumor can cause significant morbidity and mortality, because of delayed diagnosis in the majority of cases, contributing to a worse prognosis of the disease. Objectives: To assess epidemiology, clinical aspects and treatment of breast cancer in men. Subjects and methods: A descriptive retrospective study was carried out to investigate 25 cases of male breast cancer in the municipality of Campinas, diagnosed at the Celso Pierro General and Maternity Hospital (PUC-CAMPINAS), in the Women?s Integral Healthcare Center (CAISM-UNICAMP) and in the Laboratory of Anatomic Pathology of the Campinas Maternity Hospital, from 1992 to 2005. Data was collected from patient medical records with the purpose of evaluating clinical history, personal and family history, anatomic pathology diagnosis, treatment performed and clinical course. Results: Since this was a descriptive study of a rare disease with a small case study, statistical analysis was not conducted. Data was reflected in the frequencies and means of the variables studied. Regarding the age group, three patients were identified as being less than 40 years of age, seven patients were aged from 41 to 60 years and 15 patients were aged over sixty years. In the present study, 22 patients were white, one was black and two were mulatto. The percentage distribution according to the time since the first symptoms appeared until the time of diagnosis showed that seven patients were diagnosed no longer than six months after symptoms appeared, six patients were diagnosed from seven to 12 months after the first symptoms appeared, five patients were diagnosed two years after the first symptoms appeared and seven patients were diagnosed more than two years after the first symptoms appeared. The presenting complaint in all patients was a breast lump, and the predominant histologic pattern observed was Invasive Ductal Carcinoma, present in 23 cases. The surgical treatment of choice was mastectomy. Six radical mastectomies, 17 modified radical mastectomies, one simple mastectomy and one lumpectomy were performed. Conclusion: The current study corroborates data obtained from the literature, indicating that breast cancer was identified at a later stage in men. There was a significant delay in diagnosing cancer after the first symptoms appeared. More than half of the patients studied were diagnosed with breast cancer at an advanced stage of the disease
