Abstract
Prior to undergoing second-look laparotomy, 57 patients with ovarian cancer were evaluated with computed axial tomography (CT). All patients were clinically free of disease following chemotherapy. At laparotomy, 25 patients had visible evidence of disease, 9 had microscopic disease only, and 23 were free of cancer. Tumor was correctly identified on CT in 9 of the 25 patients (36%) with macroscopic disease. Tumors smaller than 2 cm in size were not detected by CT. CT suggested disease in 8 of the 32 patients (25%) who were free of macroscopic disease. CT provides useful information when it is abnormal. Fine needle aspiration of suspicious areas can spare some patients laparotomy. However, CT has a significant false-negative rate due to its inability to detect small volume disease. Patients with negative CT will continue to require reexploration and tissue confirmation to assess the need for further therapy.
