Does Metastatic Lymph Node Ratio Accept As a Prognostic Factor in the Patients Underwent Lymphadenectomy with Less Than 15 Lymph Nodes for Gastric Cancer?

Background. The necessity of accurate lymph node staging is a vital while evaluating different treatment consequences. This study evaluates the metastatic lymph nodes (pN)and the comprehensive use of ratio of lymph nodes as a prognostic factor in the patients with gastric cancer underwent the surgery. Method. Review of 88 consecutive patients with gastric adenocarcinoma. The association between the number of resected lymph nodes and the number of metastatic lymph nodes was analysed and evaluated with other prognostic factors. Results. The number of lymph node metastases increased with the number of resected lymph nodes. In the study. ROC curve of both variables did not show difference (0.692, 0.709) but both variables was used as a significant prognostic factor (p<0.0001). According to the multivariate analysis the hazard ratio for the pN stages showed a significant increase (p=0.006, HR=1.8, 1,184-2,671 in 95%CI) with significant difference, which favored pN stages as a better prognostic factor against the ratio. Conclusions. we confirmed the ratio of lymph node was not demonstrated an eventful variable which was a prognostic for survival when comparing with pN stages while the surgery provided less than 16 lymph nodes removed along with the whole specimen in this limited series.
