CNB Useful in Assessing Salivary Gland Lesions

How sensitive and accurate is core needle biopsy (CNB) for salivary gland lesion assessment?

Background: Accurate pre-operative benign/malignant salivary gland tumor categorization is crucial in planning a correct surgical resection. Historically, fine needle aspiration (FNA) has been used with multiple imaging modalities, but in certain circumstances FNA has limitations. Recent studies show a role for CNB in pre-operative evaluation, but CNB also has some disadvantages. Its exact evaluation role has yet to be defined.

Study design: Database review of studies from PubMed, Embase, CAB Abstracts, CINAHL, BIOSIS, LILACS, PakMediNet, Trip Database, and the National Guideline Clearinghouse.

Setting: Department of Pathology and ARUP Laboratories, University of Utah, Salt Lake City.
