AIM: Total lymphocyte count in preoperative peripheral blood is associated with prognosis in various cancers. The predictive value of preoperative total lymphocyte count for survival was assessed in older gastric cancer patients after gastrectomy. METHODS: A total of 200 gastric cancer patients aged ≥75 years who underwent curative resection from 2000 to 2014 were included in this retrospective study. The cut-off value of total lymphocyte count in preoperative peripheral blood was determined using receiver operating characteristic curve analysis, and the association with prognosis was examined. RESULTS: The cut-off value of total lymphocyte count was 1462/μL, and 94 patients were classified as low total lymphocyte count patients and 106 patients were classified as high total lymphocyte count patients. In univariate analysis, American Society of Anesthesiologists score ≥3, Charlson Comorbidity Index ≥3, total lymphocyte count <1462/μL, stage III, open approach, total gastrectomy, splenectomy and infectious complication were significantly associated with overall survival. In multivariate analysis, total lymphocyte count <1462/μL (P = 0.003), American Society of Anesthesiologists score ≥3 (P = 0.01) and stage III (P = 0.017) were independent prognostic factors. Low total lymphocyte count significantly reduced overall survival in stage I (P = 0.037) and II (P = 0.009) patients, but not stage III patients (P = 0.29). CONCLUSION: Total lymphocyte count in preoperative peripheral blood can predict postoperative survival of older patients with relatively early-stage gastric cancer.
