BACKGROUND: To perform a meta-analysis of retrospective studies exploring the association of C-reactive protein to albumin (CAR) with overall survival (OS) in patients with lung cancer. METHODS: Relevant studies were enrolled by searching databases of PubMed, Cochrane Library, Web of Science, and Embase were searched until July 16, 2017. We combined the hazard ratios (HRs) and 95% confidence intervals (CIs) to assess the correlation between CAR and OS in patients with lung cancer RESULTS:: Four studies involving 1257 participants from several countries were involved in the meta-analysis. In a pooled analysis of all studies, elevated CAR predicted poor OS (HR: 2.13; 95% CI: 1.52-2.97; Pâ<â.05). Subgroup analysis showed that high level of CAR predicted poor OS in patients with lung cancer though multivariate analyses on 1092 participants (HR: 1.63; 95% CI: 1.24-2.51; Pâ<â.001) and the heterogeneity decreased to 45.4%. Moreover, a similar trend was observed in patients receiving surgery (HR: 2.64; 95% CI: 2.08-3.35; Pâ<â.001) and chemotherapy (HR: 1.75; 95% CI: 1.93-2.57; Pâ=â.004). And the HRs for patients receiving surgery was moderately higher than that for patients receiving chemotherapy. CONCLUSION: Our findings indicate that CAR may have a prognostic value in lung cancer as we detected a significant association between elevated CAR and poorer OS. However, further studies are warranted to draw firm conclusions.
