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

文摘目的:系统评价地诺孕素治疗子宫腺肌病的疗效及安全性,为临床用药提供循证依据。方法:计算机检索PubMed、EMbase、Cochrane Library、中国生物医学文献数据库、CNKI和万方数据库,检索时限均为建库至2023年7月30日,纳入地诺孕素(试验组)对比阳性药物或安慰剂(对照组)治疗子宫腺肌病的随机对照研究(RCT)。筛选文献、提取资料后采用Cochrane 5.1.0偏倚风险评估工具对纳入文献质量进行评价,采用Rev Man 5.3统计软件进行meta分析。结果:纳入10篇RCT研究,共820例患者。Meta分析结果显示,试验组较对照组VAS评分显著降低(SMD=-2.50,95%CI为-4.73~-0.27,P=0.03),对于子宫体积变化疗效相当(MD=0.24,95%CI为-0.87~1.36,P=0.67),试验组的临床有效率显著高于对照组(RR=1.30,95%CI为1.19~1.41,P<0.01),患者的CA125水平两者差异不大(MD=-4.25,95%CI为-13.16~4.66,P=0.35),两者的潮热副反应发生率(RR=0.72,95%CI为0.03~15.53,P=0.83)、异常子宫出血发生率(RR=2.11,95%CI为0.87~5.15,P=0.10)相当。结论:地诺孕素组的疼痛缓解较安慰剂组有明显优势,与阳性对照组相比,疗效差别不大;临床有效率显著高于阳性对照组,子宫体积变化、CA125水平与阳性对照组和安慰剂组疗效均相当;安全性方面,潮热副反应发生率与阳性对照组和安慰剂组均相当,异常子宫出血的发生率与阳性对照组相当,但显著高于安慰剂组,因此应用地诺孕素时要警惕子宫出血的风险。未来仍需大规模随机对照研究去验证。
