Kaplan-Meier method was used to calculate the survival rate, Log-Rank time series test was used to perform univariate analysis and proportional hazards model (Cox model) to analyze multivariate analysis. Results The 1, 3, 5-year survival rates of patients undergoing radical operation for gastric cancer were 80.6%, 49.5% and 35.5% respectively. Four factors, smoking habits, sleep status, physical activity and understanding of patients’ condition, became independent The prognostic factors.
