CDCA4 and neoplasm: Both miR-29c-3p and CDCA4 were associated with regional lymph node staging (N staging), distant metastasis (M staging), tumor diameter, and pathological differentiation (P < 0.05), and miR-29c-3p is also closely correlated with tumor invasion staging (T staging) (P < 0.05) (see Figure 1 and Table 1).
