| Popis: | Preoperational hemogram parameters have been reported to be associated with the prognosis of several types of cancers. This study aimed to investigate the prognostic value of hematological parameters in gastric cancer in a Chinese population. A total of 870 gastric cancer patients who underwent radical tumorectomy were recruited from January 2008 to December 2012. Preoperative hematological parameters were recorded and dichotomized by time-dependent receiver operating characteristic curves. The survival curves of patients stratified by each hematological parameter were plotted by the Kaplan–Meier method and compared by log-rank test. Multivariate Cox proportional hazards models were used to select parameters independently correlated with prognosis. The median age of the patients was 60 years. The median follow-up time was 59.9 months, and the 5-year survival rate was 56.4%. Results from the univariate analyses showed that low lymphocyte count ( 0.55), low lymphocyte-to-white blood cell ratio (LWR 1.44), and high platelet-to-lymphocyte ratio (PLR > 115) were associated with poor survival of gastric cancer patients. Multivariate analysis showed that low LMR (HR: 1.49, 95% CI: 1.17–1.89, P = .001) was the only hematological factor independently predicting poor survival. These results indicate that preoperational LMR is an independent prognostic factor for patients with resectable gastric cancer. |
