Diagnostic Accuracy of Fine Needle Aspiration Cytology in Palpable Lesions of Head and Neck in Comparison to Histopathology
Journal Title: International Journal of Contemporary Medical Research - Year 2017, Vol 4, Issue 2
Abstract
Introduction: Head and neck lesions are superficial and easily accessible to fine needle biopsy. A reliable fine needle aspiration if available is an advantage to both the patient and surgeon as the technique is rapid, safe, cost – effective. It provides reliable accurate diagnosis in most of the cases. Fair patient acceptability, repeatability and avoidance of unnecessary surgical procedure have made FNAC as a popular investigation. FNAC being simple, least traumatic and fairly economical has become a popular outpatient procedure in diagnosing the exact nature of various head and neck lesions. Current research aimed to study the accuracy of cytopathological diagnosis of head and neck swellings by FNAC and to compare and analyze FNAC of head and neck swellings with that of histopathological study. Material and methods: This prospective study was conducted at department of surgery and department of pathology of government medical college and hospital during a period from July 2014 to October 2016. FNAC smears from 100 patients were examined and there correlation was done with histopathological findings. Statistics: Fischer exact test was used for the statistical analysis. Results: Out of the 100 FNAC of the head and neck lesions performed, lymph nodes (43%) were the most commonly aspirated organ followed by Thyroid (34%), Salivary Glands (15%) and Miscellaneous sites (8%). Among 100 cases, 34 cases were neoplastic and 66 cases were non-neoplastic. Histopathological correlation available in all 100 cases showed sensitivity of 90.47%, specificity of 98.73%, positive predictive value of 95% and negative predictive value of 97.5%. The association between FNAC diagnoses and histopathological diagnoses was considered to be statistically significant. Conclusion: It can be concluded that FNAC is a relatively atraumatic, well tolerated, safe procedure which can be readily performed in outpatient set up and is an excellent first line method for investigating the patients presenting with head and neck lesions. Since the lesions of the head and neck are easily accessible, FNAC is a diagnostic procedure, which suits well for such a situation. As maximum head and neck lesions are nonneoplastic, FNAC can avoid unnecessary surgeries.
