the further multivariate regression analysis showed that T stage (P<0.001), N stage (P<0.01), M stage (P<0.001), AFP (P<0.01), tumor size (P<0.01), surgery (P<0.001), and chemotherapy (P<0.001) were independent prognostic factors for OS (Figure 2), which were included in the nomogram. Here, AFP is linked to neoplasm.
