ABSTRACT

Objective To analyze the clinical data of male breast cancer (MBC),and investigate the clinical characteristics and factors potentialy affecting prognosis of male breast cancer. Methods A retrospective case-control study was performed on 17 MBC and 102 female breast cancer cases from January 1996 to 2008, treated in the hospital with pathologic proofs. Results MBC accounted for 1.15% (17/1473) of all cases. The initial visiting age was older, the time from the appearance of lump to the first doctor contact was longer, the positive rate of axiUary lymph node metastasis and local skin change incidence ratio was higher in the male group (P <0.05); there was no significant difference about overall 5-year disease-specific survival between the two groups (P >0.05), when tumor stages and nodal involvement were checked, Conclusion This study suggests that the two groups' prognosis is similar, the gender is uncertain prognostic factor.
