The expression level of circ‐TNRC6B was significantly and negatively correlated with T stage (Fig. 2C; Table S2) but was not significantly correlated with age, gender, lymph node metastasis, distant metastasis, and pathological grade (Fig. S3A–E, Table S2). Here, TNRC6B is linked to metastatic malignant neoplasm in the lymph nodes.
