Acurácia da tomografia computadorizada no diagnóstico de metástases regionais de carcinoma de células escamosas da região de cabeça e pescoço: uma revisão de literatura

Abstract

Lymph node involvement associated with the diagnosis of Squamous Cell Carcinoma (SCC) of the head and neck region affects the prognosis and survival of patients. The accuracy of Computed Tomography (CT) in the diagnosis of these regional metastases can help in the preoperative choices to be made from the positive result. The objective was to identify the accuracy of CT in cases of SCC in the head and neck region aiming at its functionality in the diagnosis of lymph node metastases. For this, a narrative review of the literature was performed and evaluated the accuracy of CT for the diagnosis of lymph node metastases in cases of head and neck SCC, using the PubMed database using the search of the last 10 years as a filter. Based on the studies described in this work, the accuracy of CT varies between 68% to 96.1%, sensitivity can vary between 31.81% to 88% and specificity varies between 29% to 100%, with reference to characteristics such as necrosis central, lymph node diameter, union of 3 or more lymph nodes, circular shape and extracapsular dissemination. Thus, CT images are relevant as a preoperative examination in the diagnosis of regional lymph node metastases in patients with SCC in the head and neck region. [resumo fornecido pelo autor]
