Popis: Whether gastric adenocarcinoma (GC) patients with adjacent organ invasion (T4b) benefit from aggressive surgery involving pancreatic resection (PR) remains unclear. This study aimed to clarify the impact of PR on survival in patients with locally advanced resectable GC. Between 1995 and 2017, patients with locally advanced GC undergoing radical-intent gastrectomy with and without PR were enrolled and stratified into four groups: group 1 (G1), pT4b without pancreatic resection (PR)
group 2 (G2), pT4b with PR
group 3 (G3), positive duodenal margins without Whipple’s operation
and group 4 (G4), cT4b with Whipple’s operation. Demographics, clinicopathological features, and outcomes were compared between G1 and G2 and G3 and G4. G2 patients were more likely to have perineural invasion than G1 patients (80.6% vs. 50%, p <
0.001). G4 patients had higher lymph node yield (40.8 vs. 31.3, p = 0.002), lower nodal status (p = 0.029), lower lymph node ratios (0.20 vs. 0.48, p <
0.0001) and higher complication rates (45.2% vs. 26.3%, p = 0.047) than G3 patients. The 5-year disease-free survival (DFS) and overall survival (OS) rates were significantly longer in G1 than in G2 (28.1% vs. 9.3%, p = 0.003
32% vs. 13%, p = 0.004, respectively). The 5-year survival rates did not differ between G4 and G3 (DFS: 14% vs. 14.4%, p = 0.384
OS: 12.6% vs. 16.4%, p = 0.321, respectively). In conclusion, patients with T4b lesion who underwent PR had poorer survival than those who underwent resection of other adjacent organs. Further Whipple’s operation did not improve survival in pT3–pT4 GC with positive duodenal margins.
