More interestingly, the Cox’s multivariate hazard regression model demonstrated that ATG-5 and MRP-1 expression levels and TNM stages were all independent and significant prognostic indicators for predicting the OS (P = 0.037, P = 0.005, P<0.001 respectively) and DFS (P = 0.004, P = 0.008, P<0.001 respectively) of GC (Table 3). The gene discussed is ATG5; the disease is gastric cancer.
