A systematic review and meta-analysis of the diagnostic accuracy of ultrasound-guided core needle biopsy for salivary gland lesions.
American Journal of Clinical Pathology 2011 October
Core needle biopsy (CNB) of salivary gland lesions is a relatively new technique that may offer benefits for diagnosis of the lesions. We conducted a systematic literature review to identify studies published between January 1, 1985, and March 15, 2011. Summary estimates of sensitivity and specificity were obtained by using a summary receiver-operating characteristic (SROC) curve. Study quality was assessed by using the QUADAS survey. We identified 5 studies (277 cases) for inclusion. The area under the SROC for CNB was 1.00 (95% confidence interval [CI], 0.99-1.00). Based on histologically verified cases, the sensitivity of CNB is 0.92 (95% CI, 0.77-0.98) and the specificity is 1.00 (95% CI, 0.76-1.00). We conclude that CNB has high accuracy and a low (1.2%) inadequacy rate. CNB is more accurate than fine-needle aspiration, at least in some settings, but the best selection of which test to use for an individual patient and setting remains to be defined.
