Methods...Objective: To compare with fiveyear survival after surgery for the 116 breast cancer patients treated at the First Teaching Hospital (FTH) and the 866 breast cancer patients at Hpital du SaintSacrement (HSS). Methods: Using Cox regression model, after eliminating the confounders, to develop the comparison of the fiveyear average hazard rates between two hospitals and among the levels of prognostic factors. Results: It has significant difference for the old patients (50 years old or more) between the two hospitals. Conclusion: Tumor size at pathology and involvement of lymph nodes were important prognostic factors.展开更多
