The accuracy of clinical staging of stage I-IIIA non-small cell lung cancer by using thoracic computed tomography

Purpose: To assess the accuracy of clinical staging stage I-IIIA non-small cell lung cancer (NSCLC) by using thoracic computed tomography (CT). Patients and Methods: Medical records patients with NSCLC operated in two years 2018-2019 at Surgery Department No 2, HCMC Oncology Hospital were studied retrospectively. Results: Thoracic CT diagnosed tumor an 79% but failed to detect T3-4 disease 8% cases. Of nodal disease, had a diagnostic 58% misclassified N2 18% Agreement was poor between pathologic (Kappa coefficient= 0.186). Only 48% accurately, clinically understaged (45%) more frequent than overstaged one. low sensitivity only 19% detecting IIIA 13 (21%) missed diagnosis. Conclusion: is not ideal means for cancer. prevent worsened outcomes associated inaccurate staging, physicians should rely on established guidelines. Key words: cancer,
