Abstract
Objectives: The present study aims to determine the diagnostic accuracy of computed tomography
(CT) - guided transthoracic core needle biopsy of pulmonary tumorsand the complications of the procedure.
Methods: A retrospective descriptive studywas carried out in a series of patients with pulmonary tumors
diagnosed by CT - guided transthoracic core needle biopsy at Binh Dan Hospital between 3/2019 and 12/2019.
Results: The total sample was 57 patients with an average age was 60.7, male/female = 1.85. Most
of the patients were detected lung tumors incidentally (78.9%), and right-side tumors were more than the
left - side tumors. Biopsy results included cancer, inflammation, and tuberculosis, with incidence rates were 57.9%, 35.1%, and 7%, respectively. The cases, which were confirmed tuberculosis on biopsy results,
were determined tuberculosis by a specialist who worked in Pham Ngoc Thach Hospital. The patients had
inflammatory results and were operated on, which had surgical outcomes were tuberculosis (50%), cancer
(20%), and inflammation (20%). The cases, which were confirmed cancer on biopsy results after comparing
with surgical outcome, found that the biopsy of detecting lung cancer had 85.7% sensitivity, 100% specificity,
100% positive predictive value, and 80% negative predictive value. The rate of complications was 21.1%,
including pneumothorax (12.3%), hemoptysis (7%), and pulmonary parenchymal hematoma (1.8%). The
rate of pneumothorax requiring emergency pleural drainage was low (3.5%).
Conclusions: CT - guided transthoracic core needle biopsy is feasible, highly effective, and relatively
safe; therefore, it plays an important role in diagnosing lung tumors.
