 Survival Analysis with SAS- A Complete Project

Problem and Aim of this projects: The aim of the current study was to use survival data analysis methods to assess the effectiveness of different treatment modalities on time to breast cancer recurrence in a sample of breast cancer patients. More specifically, we examined the relative effectiveness of surgery combined with chemotherapy or hormone therapy (CHT) versus surgery alone in primary breast cancer patients. We hypothesize that the combination of surgery and CHT will increase the survival time of patients, compared to surgery alone. 

Data Set: Data for this project were obtained from the Rotterdam dataset,13,14 which contains data from the records of primary breast cancer patients in the Rotterdam tumor bank.15,16 Tissue samples were obtained from 2,982 patients.15,16 Patients were included if they had a diagnosis of primary, operable breast cancer and had had surgical treatment (mastectomy or removal of breast tumor). Exclusion criteria were tissue samples taken from a biopsy, rather than from breast tumors directly; diagnosis of carcinoma; metastatic disease; pre-surgical treatment; and patients who did not have enough follow-up documentation.15 The follow-up time for the original dataset was between 1 to 231 months, with a median follow-up time of 107 months
