Accuracy of Fine Needle Aspiration Cytology of Salivary Gland Lesions in Thailand

چکیده
Salivary gland tumors are uncommon, the world wide annual incidence of salivary gland tumors ranges from 0.4 to 13.5 cases per 100 000 population (Auclair et al., 1991). Tumors of salivary glands account for 2% to 6.5 % of head and neck neoplasms and 21% to 46% are malignant (Ellis & Auclair, 1996). In Bangkok, during the period 2001-2003, the estimated age standardized incidence rate of salivary gland malignant tumor was 0.6 and 0.5 per 100,000 population for males and females, respectively (Khuhaprema et al., 2010). Fine needle aspiration (FNA) cytology plays an important role in the evaluation of salivary gland lesions. It has been used to differentiate nonneoplastic lesions from neoplasms, and benign from malignant neoplasms (Frable & Frable, 1991; Cristallini et al., 1997; Al-Khafaji et al., 1998). It is a safe, simple, cost-effective, accurate and minimal invasive for evaluation salivary gland lesions (Frable & Frable, 1991; Layfield & Glasgow, 1991; Cajulis et al., 1997; Buley & Roskell, 2000). It is not only useful in planning definitive preoperative diagnosis

Diagnostic Accuracy of Frozen Section in Comparison With Fine Needle Aspiration Cytology in Thyroid Lesions – A Prospective Study
Background and Objectives: Thyroid gland because of its superficial location is amenable to direct physical examination. Clinical assessment of thyroid lesions by means of physical examination, thyroid scans and ultrasonography is not completely reliable. Fine needle aspiration cytology (FNAC) is the most cost-effective, safe and an initial diagnostic test in the pre-operative evaluation of thy...

Background and objective: Fine needle aspiration cytology (FNAC) of salivary gland lesions is an accepted and useful diagnostic tool to differentiate between benign and malignant lesions. Majority of the neoplasms are benign, and specific diagnosis on cytology can be made in most of the cases. However, the utility is limited by the overlapping and heterogeneous morphol...

BACKGROUND Core needle biopsy is a relatively new technique used to diagnose salivary gland lesions, and its role in comparison with fine needle aspiration cytology needs to be refined. METHODS We compared the results of 228 ultrasound-guided core needle biopsy and 371 fine needle aspiration procedures performed on major salivary gland tumors with their postoperative histological diagnoses. ...

Fine-needle aspiration cytology guided by ultrasound imaging is a widely used diagnostic tool to evaluate neoplastic or inflammatory lesions of salivary glands. From February 2002 to February 2008 all the parotid lesions removed surgically in our Unit of Otolaryngology were reviewed. Study focused on sensitivity, specificity, accuracy, predictive values, likelihood ratios, and Kappa statistics ...
