Abstract
Objective: Radical surgery is the mainstay treatment for adenocarcinoma of the esophagogastric junction. The presence of microscopic residual tumor tissue after curative-intent surgery is associated with recurrence. This study compared the outcomes of patients with microscopic residual tumor (Residual+ group) and those without microscopic residual tumor (Residual- group). Material and Methods: We retrospectively reviewed the medical records of 71 patients with adenocarcinomas of the esophagogastric junction who underwent curative-intent surgery between January 2005 and August 2018. We evaluated the clinical and pathological characteristics and compared recurrences, rates and patterns, between groups. Five-year overall survival (OS) and 3-year disease-free survival (DFS) were analyzed by Kaplan-Meier analysis. Results: Nineteen (26.8%) patients had microscopic residual tumors, consisting of 8 (11.3%) with positive resection margins, 10 (14.0%) with malignant cells from peritoneal washing fluid cytology, and 1 (1.4%) with both. The median OS in the Residual- group was significantly better than that in the Residual+ group (31.3 vs 11.9 months, P = 0.003). The Residual- group had better 5-year OS (26.2% vs 11.9%, P = 0.015) and 3-year DFS (24.4% vs 9.8%, P = 0.003) than the Residual+ group. During follow-up period, 48% of the patients in the Residual+ group experienced recurrent disease, with a median follow-up time at 7.7 months. Distant metastasis was the most common site of recurrence. Conclusion: Microscopic residual tumor after resection is associated with poorer survival outcomes and higher recurrence rates. Curative surgery should aim to achieve R0 resection in all patients with resectable adenocarcinomas of the esophagogastric junction.
