Abstract
Introduction: Ultrasonography (USG) has been underutilized for image guided biopsy or FNA of suspected lung cancer, despite its advantages over computed tomography (CT). USG can be effective for guiding FNA/ biopsy of peripheral lung / pleural/ mediastinal lesions and extra-thoracic metastatic lesions. This study was aimed to find diagnostic yield of USG guided biopsy or FNA in suspected lung cancer. Methods: Retrospective cross-sectional study was done in lung cancer suspects sent to Radiology department of Bhaktapur Cancer Hospital for biopsy or FNA. USG guided biopsy or FNA obtained from either lung lesions or extrapulmonary lesions based on their size and feasibility. Semiautomatic biopsy instrument (18G x 16 cm) with Co-axial needle (17G) was used for biopsy and 22G spinal needle or hypodermic needle was used for FNA. Cytology/ histopathology report of these subjects were then retrieved. Data analysis was done with Microsoft Excel 2016. Results: USG guided biopsy or FNA was done in 178 subjects, with 30 subjects lost to follow up. Diagnostic yield of USG guided biopsy and FNA was 94.7% and 79.4% respectively. Overall diagnostic yield was 91.2%. Malignancy was seen in 125 subjects, most common being adenocarcinoma, followed by squamous cell carcinoma and small cell carcinoma. Most of the malignancy was seen in older age group (61-80 years), squamous cell carcinoma being more common in elderly as compared to other malignancies. Conclusion: The study showed high diagnostic yield of USG guided biopsy or FNA in suspected lung cancer with higher diagnostic yield of biopsy over FNA.
