Diagnostic Accuracy of a Computed TomographyGuided Transthoracic Needle Biopsy for GroundGlass Opacities and Subsolid Pulmonary Nodules
CUREUS JOURNAL OF MEDICAL SCIENCE(2024)
摘要
Purpose The increasing use of computed tomography (CT) imaging has led to the detection of more ground -glass nodules (GGNs) and subsolid nodules (SSNs), which may be malignant and require a biopsy for proper diagnosis. Approximately 75% of persistent GGNs can be attributed to adenocarcinoma in situ or minimally invasive adenocarcinoma. A CT -guided biopsy has been proven to be a reliable procedure with high diagnostic performance. However, the diagnostic accuracy and safety of a CT -guided biopsy for GGNs and SSNs with solid components <= 6 mm are still uncertain. The aim of this study is to assess the diagnostic accuracy of a CT -guided core needle biopsy (CNB) for GGN and SSNs with solid components <= 6 mm. Methods This is a retrospective study of patients who underwent CT -guided CNB for the evaluation of GGNs and SSNs with solid components <= 6 mm between February 2020 and January 2023. Biopsy findings were compared to the final diagnosis determined by definite histopathologic examination and clinical course. Results A total of 22 patients were enrolled, with a median age of 74 years (IQR: 68-81). A total of 22 nodules were assessed, comprising 15 (68.2%) SSNs with a solid component measuring <= 6 mm and seven (31.8%) pure GGNs. The histopathological examination revealed that 12 (54.5%) were diagnosed as malignant, nine (40.9%) as benign, and one (4.5%) as non -diagnostic. The overall diagnostic accuracy and sensitivity for malignancy were 86.36% and 85.7%, respectively. Conclusion A CT -guided CNB for GGNs and SSNs with solid components measuring <= 6 mm appears to have a high diagnostic accuracy.
