TPX2 and metastatic malignant neoplasm in the lymph nodes: High expression of TPX2 was significantly associated with the patient’s age (<65 vs. ≥65, p < 0.001), type of histology (differentiated vs. undifferentiated, p = 0.002), depth of tumor (T1 vs. T2 vs. T3 vs. T4, <0.001), lymph node metastasis (N0 vs. N1 vs. N2 vs. N3, p < 0.001), stage (I vs. II vs. III vs. IV, p < 0.001), and remote metastasis or recurrence (presence vs. absence, p = 0.02; Table 1).
