Lymph node ratio as a novel and simple prognostic factor in advanced gastric cancer

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.

4561 Purpose: To determine the prognostic significance of the lymph node ratio (ratio of number of positive lymph nodes to number of dissected lymph nodes) in gastric cancer patients. Methods: We retrospectively analyzed 10,176 gastric patients from 1990–2003 who underwent curative gastrectomy from the SEER database. Survival curves were calculated according to the Kaplan-Meier method and analyzed with log-rank test. Multivariate analysis of prognostic factors related to survival was performed by the Cox proportional hazard model. Results: The lymph node ratio (LNR) was a strong predictor of survival. LNR was equally predictive of survival whether the analysis was restricted to patients with <15 lymph nodes dissected or >15 lymph nodes dissected. Survival of patients with a LNR of 0.1–5% was not significantly different than node negative patients; however, survival of patients with a LNR of 5–10% was significantly different than node negative patients. Multivariate analysis showed that LNR, T-stage, tumor size, and number of lymph nodes positive were independent prognostic predictors of death and that LNR was the strongest predictor for death. Multivariate analysis showed that the number of lymph nodes dissected was an independent prognostic factor for survival. Moreover, LNR was an independent prognostic factor for N1 and N2 patients by AJCC staging. LNR trended toward significance in AJCC N3 patients. Conclusions: LNR was the strongest predictor of death in gastric cancer patients when compared to T-stage, number of lymph nodes positive, and tumor size. LNR is equally predictive regardless of the adequacy of the lymph node dissection. No significant financial relationships to disclose.

Abstract Background: Lymph node status in gastric cancer is known as an independent prognostic factor that guides the surgical and oncological treatment and independently influences long-term survival. Several studies suggest that the lymph node ratio has a greater importance in survival than the number of metastatic lymph nodes. Aim: The aim of this study was to evaluate the clinical and morphological factors that can influence the survival of gastric cancer patients, with an emphasis on nodal status and the lymph node ratio. Material and methods: We conducted a retrospective study in which 303 patients with gastric cancer admitted to the Department of Surgery of the Mureș County Hospital between 2008 and 2018 were screened for study enrolment. Data were obtained from the records of the department and from the histopathological reports. The examined variables included: age, gender, tumor localization, T stage, histological type, grade of differentiation, surgical procedure, lympho-vascular invasion, excised lymph nodes, metastatic lymph nodes, lymph node ratio. After screening, the study included a total number of 100 patients, for which follow-up data was available. Results: The mean age of the study population was 66.43 ± 10 years, and 71% were males. The average survival period was 21.42 months. Statistical analysis showed that the localization of the tumor (p = 0.021), vascular invasion (p ---lt---0.001), T (p = 0.004) and N (p ---lt---0.001) stages, type of surgery (partial gastrectomy 59% vs. total gastrectomy 41%, p = 0.005), as well as the lymph node ratio (p ---lt---0.001) were prognostic factors for survival in patients with gastric cancer undergoing surgical therapy. Conclusions: The survival of gastric cancer patients is significantly influenced by tumor localization, T stage, vascular invasion, type of surgery, N stage and the lymph node ratio based on univariate analysis. Also, the lymph node ratio proved to be an independent prognostic factor for survival.
