Purpose: Abdominal lymph node (ALN) recurrence in gastric cancer (GC) is rare and usually unresectable. We investigated the effects of integration of radiotherapy (RT) and chemotherapy against ALN recurrence in GC. Methods: We retrospectively categorized GC patients with ALN recurrence treated between 2005 and 2013 into two groups: those treated with integration of RT and chemotherapy (RCT) and those who received systemic chemotherapy only (CT). The median follow-up period after ALN recurrence for all patients was 20 months. Results: Of 53 patients, 31 and 22 were in the RCT and CT groups, respectively. Isolated distant failure (DF; 35.5%) without local progression (LP) was the dominant pattern of failure (POF) in the RCT group (median DF-free period, 26 months). LP followed by DF (31.8%) was the dominant POF in the CT group; LP (median LP-free period, 8 months) occurred 10 months earlier than DF (median DF-free period, 18 months). RCT patients had significantly longer median progression-free survival (PFS) compared to CT patients (25 vs. 8 months; P = 0.021). On multivariate analysis, treatment (CT vs. RCT) was an independent prognostic factor for PFS (hazard ratio 2.085; 95% confidence interval 1.073–4.050; P = 0.013). Conclusions: Integration of RT and chemotherapy achieved long-term local control and prolonged PFS in GC patients with ALN recurrence. Local RT is feasible for treating isolated ALN recurrences.
