Aim: To evaluate the recurrence risk for Siewert type II esophagogastric junction carcinoma treated with curative resection.
Patients and methods: We retrospectively analyzed clinicopathological and recurrence-free survival (RFS) data of 52 patients after curative resection for Siewert type II carcinoma focusing on the role of lymph node metastasis around the greater curvature or parapyloric area.
Results: Recurrence was observed in 21 (40%) patients; the median time-to-recurrence was 11 months (range=3-33 months). According to multivariate Cox proportional hazard regression analysis, involvement of nodes no. 4sa, 4sb, 4d, 5 and/or 6 (odds ratio (OR)=6.62; 95% confidence interval (CI)=1.27-41.1; p=0.04) and younger age (OR=2.10; 95% CI=1.25-3.82; p<0.01) were significant independent risk factors affecting RFS.
Conclusion: Involvement of no. 4-6 nodes appears to predict recurrence of Siewert type II carcinoma treated with curative resection. Patients with this risk factor may benefit from effective use of perioperative chemotherapy.
