[Diagnostic accuracy and safety of US-guided core needle biopsy versus fine needle aspiration biopsy of thyroid nodules: a Meta analysis].

ABSTRACT

Objective:To evaluate the efficacy and safety of core needle biopsy (CNB) and fine neon needle aspiration biopsy (FNAB) in the diagnosis of thyroid nodules.Method:The CNKI, Wanfang database, China Biomedical Literature Database (CBM), PubMed, Cochrane Library, EMBASE, Web of Science database (the deadline of February 2017) were used to search the literature on CNB and FNABCNB. Two reviewers independently screened the literature according to the inclusion and exclusion criteria, extracted the data and evaluated the quality of the literature, and used RevMan 5.3 software for Meta analysis.Result:The accuracy of the CNB group was higher than that of the FNAB group(RR= 1.14, 95%CI 1.06-1.22, P< 0.01). Meta analysis showed that the accuracy of CNB group compared with FNAB group was statistically significant the difference was statistically significant. There was no significant difference between the two groups (RR= 0.92, 95%CI0.67-1.25, P> 0.05).Conclusion:CNB is safe and feasible in the diagnosis of thyroid nodules under the condition of mastery of puncture technique.
