Abstract

Objectives: The presence of adenopathies can be evaluated clinically by tomographic imaging. The aim is to assess if computed tomography (CT) provides additional information that may influence therapeutic decisions.

Methods: Retrospective review of medical records of patients undergoing surgery of the larynx and neck dissection for cancer between May 2001 and December 2010.

Results: Of the 31 patients clinically and radiographically staged as N0, 26 were confirmed by pathology (83.9%) and 5 cases had metastatic lymph nodes (16.1%). Of the three patients clinically staged as N0 and staged by imaging as N> 0 in 2 was confirmed the presence of adenopathies by pathology (66,7%). Of the 6 patients clinically N> 0, CT staged as N> 0 5 patients who were confirmed to be N> 0 by pathology (100%). In this study CT showed sensitivity, positive predictive value and negative predictive value superior to the clinic.

Conclusion: CT appears to enhance the predictive value in detecting cervical metastases, but the percentage of occult neck metastases currently imposes a neck dissection in N0 necks.
