Computed tomography in the evaluation of clinical stage IB carcinoma of the cervix.

A retrospective analysis of 47 cases of clinical stage IB cervical carcinoma radiologically staged with computed tomography (CT) was undertaken. There were no cases where CT provided information which altered staging. In 5 cases, CT suggested extension of disease beyond the cervix which was not confirmed surgically or with other staging procedures. In 3 cases, one or more normal-sized obturator or internal iliac nodes with metastatic disease were discovered at surgery, but the high common iliac and periaortic nodes were disease free. We conclude that routine use of CT in patients with clinical stage IB cervical carcinoma is not warranted unless the patient's body habitus precludes accurate physical examination.
