SOCS6 and neoplasm: Subsequently, tumor size (P=0.007, HR=2.49, 95%CI: 1.27~4.56), necorsis of tumor (P=0.001, HR=3.03, 95%CI: 1.54~5.95), mitotic index (P=0.023, HR=2.11, 95%CI: 1.11~4.02), and low SOCS6 expression (P=0.009, HR=2.58, 95%CI: 1.27~5.24) were demonstrated by multivariate Cox proportional hazard regression model analysis to be independent predictive factors for OS (shown in Table 2).
