Background: Lymph node (LN) status is a predictor of recurrence after gastrectomy for gastric adenocarcinoma. Clinicopathologic predictors of recurrence in patients with node-negative disease are less well established. Methods: Patients who underwent surgery with curative intent for gastric adenocarcinoma from between 2000-2012 from participating institutions of the U.S. Gastric Cancer Collaborative were analyzed. Patients who died within 30 days of surgery were excluded. Univariate (UV) and multivariate (MV) analysis of clinicopathologic factors was associated with recurrence was performed. Results: Nine-hundred sixty-five patients from seven institutions were included in the analysis. Three-hundred forty-five (36%) had LN- disease, of whom 63 (18%) had disease recurrence after a median follow-up of 24 months. The most common patterns of recurrence were: peritoneal alone (44%), liver (22%), or combined liver/peritoneal (9%). This distribution did not differ significantly from LN+ disease. UV analysis identified tumor size, linitis plastica, diffuse histology, poor differentiation, signet ring histology, T stage ≥3, perineural invasion, and lymphvascular invasion as risk factors for recurrence (Table). On MV analysis, T stage≥3 (OR 3.6, 95% CI=1.7-7.5) and poorly differentiated histology (OR 2.4, 95% CI=1.2-4.9) were independent predictors of recurrence. Conclusions: Despite the presence of negative lymph nodes, patients with T stage ≥3 and poorly differentiated histology are at high risk of recurrence after gastrectomy for adenocarcinoma of the stomach. These factors, along with other patient and treatment-related variables, may be used to select patients who may benefit from more aggressive adjuvant therapy and to guide subsequent monitoring for disease recurrence.
