Accuracy of fine‐needle aspiration and imaging in the preoperative workup of salivary gland mass lesions treated surgically

Abstract

FNA is a reliable method of preoperatively assessing both benign and malignant salivary gland lesions. Preoperative imaging has a lower sensitivity and specificity than FNA in differentiating malignant from benign tumors. Older age, pain, and facial paralysis are clinical features independently associated with malignancy.

Parotid gland tumors: a retrospective study of 154 patients

“…The same trend was observed in the studied sample; i.e., imaging tests were requested only in cases where there was a significant suspicion of malignancy or involvement of adjacent structures, showing adequate sensitivity in these cases. 5 Therefore, this sample was similar to recent studies regarding the request for additional tests. CT was utilized more frequently than MRI as it was a more accessible examination in Brazil, especially considering the years comprising this study.…”

Stiffness of salivary gland and tumor measured by new ultrasonic techniques: Virtual touch quantification and IQ

“…The sensitivity and specificity of FNAC were reported to be 86% and 100%, respectively [6]. Hypocellular parotid tumors which had thinner capsules and could be vulnerable to operative rupture, especially pleomorphic adenoma, which is a common benign tumor, infrequently undergoes malignant transformation [7].…”

Primary malignant parotid epithelial neoplasm

“…The options available include ultrasound with or without the use of fine-needle aspiration biopsy [25,26], magnetic resonance imaging and computed tomography (CT) [27][28][29][30]. Despite fine-needle aspiration having different levels of accuracy based upon the malignant tumour type of salivary gland cancer -of the 10 most common malignancies identified on final histology, carcinoma expleomorphic adenoma and adenoid cystic carcinoma were more difficult to be diagnosed preoperatively [31,32]. The efficacy of combined positron emission tomography (PET)-CT has been shown to be useful in planning the most appropriate treatment by identifying clinically unrecognized disease.…”
