SUMMARY

Objective: Correlation between preoperative computed tomography, endoscopy with postoperative histopathology in the staging of laryngeal cancer.

Methods: Cross- sectional study of patients with cancer larynx who were taken a preoperative neck CT scan. Classify T stage by blinded reading of CT combined with laryngoscopy, compared with surgical results, histopathological T-stage. Analyzing the sensitivity and specificity of CT, endoscopy to staging T.

Results: There were 105 patients including 96 male patients and 9 female patients. Patients were aged from 38 to 87 (mean, 61 years). 16 (15%) patients had hypopharyngeal tumor, where's 89 (85%) had pharyngeal tumor.Sensitivity, specificity, positive predictive value, negative predictive value and accuracy of CT in staging T were 68%, 93%, 70%, 92% , 88%

Conclusion: MSCT could serve as a powerful auxiliary method for staging T laryngeal cancer, special in the evaluation of T3 and T4 tumors. Combinate information from MSCT and laryngoscopy makes improve sensitivity, specificity of preoperative staging T

Keywords: Laryngeal cancer, multislice computed tomography, laryngoscopy, T-stage.
