Some factors also can affect survival in lung cancer patients such as: grade of tumor, stage of tumor, metastasis, and type of treatment. Meta-analysis is a quantitative approach for systematically combining the results of previous researches in order to arrive at conclusions about the body of research. The aims of the study were: - To calculate the 5-year survival rate of patients with lung cancer. - To construct different models of survival rates of lung cancer according to different factors. - To perform a meta-analysis involving systematic statistical pooling of eligible studies concerning survival of lung cancer together with study results obtained from the first and second specific objectives. The present study was conducted in two phases: Phase I: to calculate the 5-year survival rates among lung cancer patients. Phase II: to conduct meta-analysis in lung cancer survival. Phase I: survival analysis The present study was conducted in the following treatment centers: - Faculty of Medicine (University of Alexandria). - Medical Research Institute ( University of Alexandria). - Gamal Abd El-Naser hospital (Health Insurance).
