4066 Background: The benefits of adjuvant chemo-radiotherapy (ChRT) over chemotherapy (Ch) for resectable gastric cancer are currently unclear. We performed a systematic review and meta-analysis (direct and indirect) of published randomized controlled trials (RCT) to compare the effects of adjuvant chemo-radiotherapy with chemotherapy on overall and disease-free survival for patients with resectable gastric cancer. Methods: We searched MEDLINE and CENTRAL from the date of inception and annual meeting proceedings of ASCO and ASTRO from 1999 to November 2012 for RCTs comparing adjuvant ChRT with Ch, adjuvant ChRT with surgery alone and adjuvant Ch with surgery alone. The primary outcome was overall survival (OS); secondary outcomes included disease-free survival (DFS) and toxicity. Hazard ratios (HR), confidence intervals (CI) and p values (p) were estimated with fixed effects models using Revman 5.1. Results: We found five trials comparing adjuvant ChRT with Ch (n = 1110), three trials comparing adjuvant ChRT with surgery alone (n = 651) and 31 trials comparing adjuvant Ch with surgery alone (n = 8273). Meta-analysis of direct comparison trials showed that adjuvant ChRT significantly improved both OS (HR 0.79, 95% CI 0.64-0.98, p = 0.03) and DFS (HR 0.76, 95% CI 0.64-0.92, p = 0.004) when compared with Ch. Subgroup analyses showed that the effects on OS and DFS were similar regardless of use of D2 nodal dissection, intensity modulated radiotherapy techniques, fluorouracil or platinum-based chemotherapy. There were no significant differences in toxicity between the two groups. The results for the direct and indirect comparisons were statistically consistent. Conclusions: There was a significant survival benefit of adjuvant chemo-radiotherapy over chemotherapy, with no increase in toxicity for patients with resected gastric cancer. Future efforts should also focus on predictive markers, and toxicity or quality-of-life assessments, to individualize adjuvant therapy and optimize the therapeutic ratio.

Abstract Background Gastric cancer (GC) is among the malignant tumors of highest morbidity and mortality in the world, and has a profile of high lymph node metastasis rate. Lymph node clearance is a critical part of gastric cancer surgery, however, the extent of lymph node clearance, for example, whether to perform abdominal aortic lymph node dissection, remains considerably controversial. In this study, we performed a systematic review and meta-analysis to assess the effects of D2 plus para-aortic lymphadenectomy (PALD) on survival and postoperative complications in patients with GC. Methods An electronic search was conducted through PubMed, Embase and cochrane library. The Q test and I 2 were used to assess heterogeneity. The publication bias was evaluated via funnel plots. All statistical analyses were performed using STATA 14.0 (STATA, College Station, TX). Results 908 studies were retrieved via literature search and eight studies were finally included. There was no significant difference between D2 and D2+PALD in the 5-year survival rate after surgery (HR: 1.00, 95% CI: 0.97-1.03, P = 0.897; I 2 = 64.9%). Besides, the 30-day mortality (RR: 1.17, 95% CI: 0.66-2.10, P = 0.590; I 2 = 0.0%) and the overall risk of postoerative complications (RR: 1.15, 95% CI: 0.83-1.59, P = 0.411; I 2 = 35.5%) were comparable between D2 and D2+PALD. Conclusion Based on current literature body, compared with D2, D2+PALD does not prevail in terms of long-term survival or perioperative outcomes.
