Treatment effect on the Survival Time of Lung Cancer Patients
The traditional treatments for lung cancer are surgery, radiation therapy, chemotherapy. When doctors make therapeutic plans, several factors will be considered, including tumor size, stage, the major type of the lung cancer, ect3. Thus, survival analysis comparing the survival time, hazardous rate of lung cancer patients among different treatment groups will provide valuable information to assess the efficacy of the treatment.
In this study, I propose to assess the treatment effect of surgery, radiation therapy and chemotherapy on lung cancer by comparing patients’ survival time and hazardous rate, adjusting for the type of the lung cancer.
1. Produce Kaplan-Meier estimates for descriptive statistics (such as the mean and median survival time of lung cancer patients in each group), plot survival curves.
2. Perform Log-rank test to compare the survival curves.
3. Use the Cox proportional hazards model to compare the hazard rates among lung cancer patients treated by surgery, radiation therapy or chemotherapy, adjusting for the type of the lung cancer.
