Total samples number were 156 breast cancer cases by used probability sampling technique with simple random sampling. The survival probability of breast cancer patients for 53 months was 59.5%. There was a significant relationship between tumor size, clinical stage, metastasis history, comorbidities and therapy types with survival probability of breast cancer patients. Meanwhile, there was no relationship between age and survival probability of breast cancer patients in several Makassar city hospitals in 2012-2016. Nevertheless, primary determinant of survival probability of breast cancer patients was clinical stage (HR=3.350) and comorbidities (HR=3.200).
