Literature screening, data extraction and literature quality evaluation were carried out independently by two researchers according to the unified classification criteria. Stata13.0 software and Meta-Disc1.4 software were used for meta-analysis.Results: A total of 14 studies with 849 cases of patients with cervical metastasis of oral cancer were included, among which 9 studies were conducted on patients, with a total of 299 patients, and 5 studies were conducted on lymph nodes, with 1965 patients with cervical lymph node proved pathologically. The results of meta analysis showed that18F-FDG PET/CT had good sensitivity and specificity in the diagnosis of cervical lymph node metastasis of oral cancer. The results showed that sensitivity = 0.81 (95% CI: 0.73-0.87), specificity = 0. 90 (95% CI: 0.83-0.94), combined likelihood ratio = 7. 9 (95% CI: 4.9-12.7), negative likelihood ratio = 0. 21 (95% CI: 0.15-0.30), diagnostic odds ratio=37 (95% CI: 20-67), and receiver operating characteristic curve =0.91 (95% CI: 0.89-0.94). Conclusions:18F-FDG PET/CT has high sensitivity and specificity in the diagnosis of cervical lymph node metastasis, and can be used as an important preoperative evaluation method for oral cancer.展开更多
