Abstract: Objective To analyze molecular classification and male breast cancer (MBC) triggers,clinical characteristics in patients with MBC and evaluate the prognosis.Methods 36 MBC patients enrolled in the past 5 years were retrospectively analyzed.100 patients with women breast cancer (WBC) in the same period were randomly selected as control group.The primary pathological type of MBC was the infiltrating ductal carcinoma.According to the expressions of estrogen receptor (ER),progesterone receptor (PR),and the epidermal growth factor receptor 2 (Her-2),the MBC can be divided into 4 kinds of molecular subtypes,Luminal type A,Luminal type B,Her-2 type,and Basal-like type.Results The ratio of MBC patients with grade Ⅲ was lower in the Luminal group A than that in the Luminal group B.There were significant differences (x2 =1.197,P ＜ 0.05) between these two groups.Conclusion The incidence rate of MBC is low but the prognosis is poor.The primary pathological type is the infiltrating ductal carcinoma.The ratio of MBC patients with grade Ⅲ is lower in the common Luminal group A than that in the common Luminal group B.
