We conducted a meta-analysis to investigate the association between preoperative controlling nutritional status (CONUT) scores in various solid tumors and clinical outcomes. Relevant studies published up to August 12, 2017 were identified using electronic databases, including PubMed, Embase, and Web of Science. The pooled hazard ratios (HR) and their corresponding 95% confidence intervals (CI) for overall survival (OS) and event-free survival (EFS) were calculated to explore the relationship between preoperative CONUT score and prognosis. In total, 674 patients with solid tumors from four published studies were included in this meta-analysis. The pooled HR for OS was 1.98 (95% CI, 1.34–2.91, p=0.001), indicating that patients with high CONUT scores had worse OS. The pooled HR for EFS was 1.98 (95% CI, 1.34–2.93, p=0.001), revealing that high CONUT scores were significantly associated with short EFS. Our data suggest that high preoperative CONUT scores indicate poor prognosis for patients with solid tumors. Further studies are needed to verify the significance of CONUT scores in clinical practice. •Preoperative inflammatory and nutritional status are related to the prognosis of patients with tumor•The CONUT score was originally used as a screening tool to assess the nutritional status of patients•Our meta-analysis suggests that preoperative CONUT scores are related to the prognosis of patients with solid tumors
