In this study, the survival rates of acute lymphocytic leukemia patients and how they differ based on demographic information, particularly race, were analyzed. Acute lymphocytic leukemia is a cancer of the blood and bone marrow which is a relatively common cancer in the United States, especially among children. An analysis was conducted using a subset of patients from the San Francisco Bay Area who had been diagnosed with the cancer in question. With death from acute lymphocytic leukemia as the event of interest, the survival analysis with the Cox PH model was used to find that there are significant racial differences in the survival rates of the cancer. Particularly, black patients are at a much greater risk of dying from acute lymphocytic leukemia than the white patients, and this disparity grows with age. There were also significant differences in survival rate based on other variables like marital status and sex. Future research might involve looking at other blood cancers and comparing the results of a separate analysis, as well as including more variables.
