The Role of Muti-Detector Thoracic Computed Tomography in Assessment of Early Stage Lung Cancer

Abstract

Objective: To characterize multi-detector computed tomography (MDCT) images of the chest and initially determine the T, N stage of early lung cancer on MDCT images.
Methods: A transverse, prospective descriptive study of 53 patients diagnosed with early-stage lung cancer based on MDCT images at K hospital between January 1, 2022, and January 1, 2023, underwent surgery and had postoperative pathology results.
Results: Early-stage lung cancer was more common over 50-yearolds (92.5 percent), more common in men (73.6 percent) than in women (26.4 percent). The most frequent histopathological type was
adenocarcinoma (77.4%). Both adenocarcinoma and squamous carcinoma are characterized mainly by solid form (66.7% and 65.8%), spiculated margin (69.3% and 66.7%), polygonal shape (70.7% and 77.8%). Cavitary lesions were more common in squamous carcinoma (22.2%). Assessment of stage T of lung cancer based on MDCT has a good consensus compared with postoperative pathology results (Kappa Index = 0.771). MDCT is a tool which has high sensitivity (73.3%) and specificity (84.2%) in pretreatment ganglion evaluation for patients.
Conclusion: MDCT is high value in the diagnosis of stage T, determining the status of regional lymph node metastases of patients with early- stage lung cancer which is the basis for selecting the most
appropriate treatment methods for patients.
