Perineural Invasion and Postoperative Complications are Independent Predictors of Early Recurrence and Survival Following Curative Resection of Gastric Cancer

PURPOSE: To investigate the clinicopathological and prognostic factors related to early gastric cancer recurrence after curative resection.

Sumario:PURPOSE: To investigate the clinicopathological and prognostic factors related to early gastric cancer recurrence after curative resection. PATIENTS AND METHODS: Between October 2006 and August 2018, a total of 149 patients with recurrence of gastric cancer/adenocarcinoma of the esophagogastric junction after curative resection were enrolled from our treatment group. A retrospective clinical analysis was performed on these patients with gastric cancer recurrence after curative resection. RESULTS: Among the 149 patients, 99 (66.4%) had only one recurrence pattern, and 50 (33.6%) had multiple recurrence patterns. The median recurrence-free survival (RFS) was 18.2 months (95% CI 15.0–21.4). Ninety-four patients (63.1%) experienced early recurrence (recurrence within 24 months after curative resection), and 55 patients (36.9%) experienced late recurrence (recurrence beyond 24 months after curative resection). The univariate analysis showed that perineural invasion (P=0.002), depth of invasion (P=0.026), postoperative chemotherapy (P=0.036) and postoperative complications (P=0.004) were significant factors associated with early recurrence after curative resection for gastric cancer. Perineural invasion (P=0.003), postoperative chemotherapy (P=0.036) and postoperative complications (P=0.042) were independent factors associated with early recurrence after curative resection in the multivariate analysis. The survival analysis showed that perineural invasion (P=0.011) and postoperative complications (P=0.007) were independent prognostic factors. The median survival time of early recurrence patients was significantly shorter than that of late recurrence patients (25.4 vs 62.9 months, P<0.001). CONCLUSION: Perineural invasion, postoperative chemotherapy and postoperative complications were independent factors associated with early recurrence after curative resection. Patients with early recurrence after curative resection had poorer survival.
