The aim of this study was to evaluate the clinicopathological features and overall survival (OS) of various subtypes of breast cancer in order to help diagnosis and guide treatment. Method: The clinicopathologic features of 1095 patients with breast cancer diagnosed over a 10–year period between 2001 and 2011were analyzed. Kaplan–Meier method was used to analyze the disease-free survival (DFS) and overall survival (OS). Calculation of hazard ratio (HR) was conducted by multivariate Cox regression.Results: According to the clinicopathologic characteristics of 1095 cases, 42% were luminal A subtype, 19.2% luminal B, 23% triple negative and 15% Her-2+. The lowest (46.88±12.59 years) and highest (50.54±12.32 years) mean age were in triple negative and Her2+ groups, respectively. There was a significant correlation between histology subtype and age, BMI, lymph node, type of surgery, and stage of disease. Overall survival (OS) and disease free survival (DFS) were significantly shorter in Her-2+ breast cancer patients (P< 0.001). Multivariate analysis showed that age had the highest hazard ratio of 2.481(CI 1.375- 4.477).Conclusion: The results of this study showed the importance of clinicopathological studies of molecular types which helps early diagnosis and identification of best strategy to treat the disease.
