Abstract :

Background: Suspected growth in the region of base of tongue, pharynx, and larynx need direct/indirect laryngoscopy for establishing Diagnosis and for Staging of the disease. The Covid 19 Pandemic has severely affected these modes of examination because they are Aerosol Generating Procedures and carry very high risk of transmission of the Virus. The Department of Head And Neck Oncosurgery at KCHRC is one of the busiest department at our Institute with an average annual footfall of around 20,000 new patients. The main objective of our study is to know the role of Image Guided Biopsy/FNAC for primary diagnosis in Head and Neck Cancers. Materials and Methods: Retrospective analysis of prospectively collected data of 35 patients was done from April to September 2020. Histopathological records along with patient’s clinical records were reviewed. Results: Of the 35 patients, 23 patients underwent CT Guided biopsies, 11 patients had CT Guided FNA and one patient had USG guided biopsy. In 23 patients (CT Guided Biopsy), the biopsy was taken from tongue in 16 patients, Larynx in two patient, Pyriform sinus(PFS), posterior pharyngeal wall, RMT (retromolar trigone), lower GBS and Tonsil sites had one patient each. Of the 11 CT Guided FNAC patients, the site of FNA was from PFS in 7 patients, Tongue in 2 patients RMT and soft palate had one patient each. One patient had undergone USG Guided biopsy for PFS lesion. Out of 35 patients, tissue specimen taken was adequate in 33 patients and inadequate in two patients. The results were supported both histologically and clinically. The histological confirmation was found in 88.6% cases (31/35), squamous cell carcinoma was found in 74.3% cases (26/35), no malignancy in 8.5% cases(3/35), no specific lesion in 5.7% cases(2/35), no definitive diagnosis in 2.8% cases(1/35) and in inadequate in 8.5% cases(3/35). Repeat biopsy in one patient revealed no malignancy. There were no post procedure complications noted. Conclusion: Image guided biopsy/FNAC is a safe, reliable minimally invasive technique and can be used for primary diagnosis of Head and Neck cancers without the risk of Aerosol generation in the current Covid -19 Pandemic.
