A potential novel biomarker in predicting lymph node metastasis of gastric signet ring cell carcinoma: A derived monocyte to lymphocyte ratio.
2021
Abstract Background This study is designed to evaluate the predictive value of derived monocyte to lymphocyte ratio (dMLR), neutrophil to lymphocyte ratio (NLR) and eosinophil to lymphocyte ratio (ELR) for lymph node metastasis (LNM) in gastric signet ring cell carcinoma (SRCC) patients. Methods We carried out a retrospective analysis for 203 eligible patients who underwent radical gastrectomy between January 2011 and September 2020. Results The diagnostic sensitivity and specificity for dMLR were 60.3% and 72.2%, respectively; while for NLR and ELR were 64.1% and 66.6%, and 91.6% and 23.6%, respectively. The dMLR and NLR were identified as independent predictors of LNM, but ELR was not. A nomogram was developed incorporating dMLR and clinical characteristics with AUC of 0.868, and the outcome of DCA supported good clinical benefit. Conclusions dMLR is a promising novel preoperative biomarker to predict LNM of gastric SRCC.
