Abstract

Background: Lung cancer is a malignancy that progresses silently from the early stages to the advanced status and lethal ending. It is the leading cause of death from all cancers according to GLOBOCAN 2020 statistics. Computed tomography is valuable in diagnosing the disease. Objectives: To describe the imaging characteristics of primary lung cancer on computed tomography and determine the value of computed tomography in diagnosing primary lung cancer. Materials and method: This cross-sectional descriptive study was conducted on 51 patients at Can Tho Oncology Hospital with clinical or chest X-ray suspicion of lung tumors, who were examined with chest computed tomography and were definitively diagnosed by histopathology through biopsy or surgical specimen collection from July 2022 to July 2024. Results: 47 out of 51 patients were definitively diagnosed with lung cancer. The average age of the cancer group was 60.47 ± 9.81 years, with a male-to-female ratio of 2.61:1. Most cancers were located in the right lung, tumor sizes >5cm and ≤7 cm were predominant (40,4%), and most patients already had secondary lesions on computed tomography images. The sensitivity and specificity of chest computed tomography in diagnosing lung cancer are 95.7% and 75%, respectively. Conclusion: Chest computed tomography imaging has a high value in diagnosing primary lung cancer.
