GNAT1 and metastatic malignant neoplasm in the lymph nodes: In univariate Cox regression analysis of OS, lnc-GNAT1-1 expression, lymphovascular invasion, depth of tumor invasion, lymph node metastasis, distant metastasis and tumor stage were identified as prognostic indicators, while in multivariate Cox regression analysis, only lnc-GNAT1-1 expression (p = 0.046), lymph node metastasis (p = 0.031) and distant metastasis (p = 0.044) could be served as independent prognostic factors (Table 2).
