Liquid base cytology in evaluation of thyroid nodules
BACKGROUND Palpable thyroid nodules are present in 4-7% of general population and Fine Needle Aspiration (FNA) is now accepted by endocrinologists and thyroid surgeons as a safe, simple and cost effective procedure for evaluating a thyroid nodule. The obtained sample can be spread directly on slides, processed as cell block preparations or prepared as liquid base smears. Liquid base method has ...
متن کاملMolecular Diagnosis Using Residual Liquid-Based Cytology Materials for Patients with Nondiagnostic or Indeterminate Thyroid Nodules
BACKGROUND Molecular analysis for common somatic mutations in thyroid cancer can improve diagnostic accuracy of fine-needle aspiration cytology (FNAC) in the nondiagnostic or indeterminate category of thyroid nodules. In this study, we evaluated the feasibility of molecular diagnosis from residual liquid-based cytology (LBC) material after cytological diagnosis. METHODS This prospective study...
متن کاملThyroid Nodules with Indeterminate Cytology
To the Editor: Alexander et al. (Aug. 23 issue)1 report findings from a prospective, multicenter gene-expression classifier validation study that raises several questions. For the 265 indeterminate fine-needle aspirates they tested, the geneexpression classifier had a sensitivity of 92%, a specificity of 52%, a positive predictive value of 47%, and a negative predictive value of 93%. Why the ob...
متن کاملImaging-Cytology Correlation of Thyroid Nodules with Initially Benign Cytology
Objective. To determine the role of imaging-cytology correlation in reducing false negative results of fine-needle aspiration (FNA) at thyroid nodules. Methods. This retrospective study included 667 nodules 1 cm or larger in 649 patients diagnosed as benign at initial cytologic evaluation and that underwent follow-up ultrasound (US) or FNA following a radiologist's opinion on concordance betwee...
متن کاملFine needle cytology of complex thyroid nodules.
OBJECTIVE To evaluate whether a preliminary aspiration (ASP) of the cystic component and/or using spinal needles in complex thyroid nodules (CTN) could improve the adequacy of cytological sampling. METHODS Between January 2004 and December 2006, 386 consecutive patients with CTN were enrolled in this prospective investigation. Ultrasound (US) fine needle aspiration cytology (FNAC) of the soli...
