MKI67 and neoplasm: No significant correlations were observed for lymph node status (N0 vs. N1, p = .12), sex (female vs. male, p = .22), tumor localization within the pancreas (head vs. body vs. tail, p = .86), extent of the primary tumor (pT1‐2 vs. pT3‐4, p = 1.0), tumor size (≤5 cm vs. >5 cm, p = .76), pathological grade (G1 vs. G2‐3, p = .28), or proliferation index (Ki67 ≤10% vs. >10%, p = .11).
