AbstractThe staging system of remnant gastric cancer (RGC) has not yet been established, with the current staging being based on the guidelines for primary gastric cancer. Often, surgeries for RGC fail to achieve the > 15 lymph nodes needed for TNM staging. Compared with the pN staging system, lymph node ratio (NR) may be more accurate for RGC staging and prognosis prediction. We retrospectively analyzed the data of 208 patients who underwent R0 gastrectomy with curative intent and who have ≤ 15 retrieved lymph nodes (RLNs) for RGC between 2000 and 2014. The patients were divided into four groups on the basis of the NR cutoffs: rN0: 0; rN1: > 0 and ≤ 1/6; rN2: > 1/6 and ≤ 1/2; and rN3: > 1/2. The 5-year overall survival (OS) rates for rN0, rN1, rN2, and rN3 were 84.3%, 64.7%, 31.5%, and 12.7%, respectively. Multivariable analyses revealed that tumor size (p = 0.005), lymphovascular invasion (p = 0.023), and NR (p < 0.001), but not pN stage (p = 0.682), were independent factors for OS. When the RLN count is ≤ 15, the NR is superior to pN as an important and independent prognostic index of RGC, thus predicting the prognosis of RGC patients more accurately.

Abstract Objective: The aim of this study was to clarify the prognostic value of the pathological lymph node ratio for elderly and non-elderly gastric cancer patients and to evaluate whether there is a difference in the survival of patients with the same LNR (Lymph Node Ratio).Materials and Methods: A total of 222 patients diagnosed with locally advanced gastric cancer and who underwent gastrectomy were included. The patients were divided into two groups according to age. Clinicopathological properties of the two groups were compared. Potential prognostic factors affecting survival were analyzed. Subsequently, the effect of lymphadenectomy and LNR on survival in both groups was evaluated. Results: Significant differences were detected in terms of the location of primary lesions, hemoglobin and albumin levels between elderly patients and non-elderly patients (p < .05). Overall survival (OS) was significantly worse in elderly patients (22 months vs. 67 months, p<0.001). The survival rates in elderly patients were significantly lower from those of non-elderly in the subgroup LNR Stage 2 (12.1% vs. 47.9 %, P = 0.004) and LNR Stage 3 classification (9.1% vs. 34.1%, P = 0.039). LNR was found to be significant for OS with a cut-off point of 0.18. Conclusion: A survival difference was found between the elderly and non-elderly patients with the same LNR. LNR was found to be an independent factor for survival especially in elderly patients. Survival was found to be further decreased in elderly patients compared to non-elderly patients with increasing LNR.
