摘要

This study aims to know the factors affecting the death probability of cancer patients in Al-Sadr General Hospital and to determine the most important variables affecting the level of risk. Cox regression models were applied to find out the risk factors that significantly affect the risk function during a period of time which includes the study of time since Diagnosis of the disease until the emergence of the event (death) or observation. The study reached of we see the marital status is the only variable affecting the survival time, it is significant at a level of significance less than the level of significance preset according to the Wald test, so the equation of final regression for Cox's is It depends only on the social status variable. As such, the Moral and Social Status affect the survival time for patients with cancer, the risk condition decreases if the patient is married and his condition is for the better.
