Risk factors for postoperative infection in Chinese lung cancer patients: A meta-analysis

The objective of this study was to identify risk factors for postoperative infection in Chinese lung cancer patients.A comprehensive search was performed in PubMed, EMbase, CNKI, and WanFang Data databases to identify studies investigating risk factors for postoperative infection in Chinese lung cancer patients. Meta-analysis was performed by using Revman 5.2 software.A total of 12 studies were included. The results of meta-analysis showed that old age, male gender, diabetes, cigarette smoking, squamous cell carcinoma, pulmonary diseases, longer of mechanical ventilation, and longer time of surgery procedure were associated with increased risk of postoperative infection. In addition, prophylactic antibiotic was associated with decreased risk of postoperative infection.The current meta-analysis suggests that the old age, male gender, diabetes mellitus, cigarette smoking, squamous cell carcinoma, pulmonary diseases, longer of mechanical ventilation, and longer of surgery time are risk factors for postoperative infection in Chinese lung cancer patients. Due to the limited quality and quantity of included studies, more high-quality studies are needed to verify the above results.
