A progressive rise in serum CA 125 concentration during follow-up monitoring of ovarian cancer after treatment of primary tumor is suggestive of a recurrence.A study was carried out in 19 patients with suspected recurrence of a previously treated ovarian carcinoma. All patients underwent ultrasonography (US), computed tomography (CT) and immunoscintigraphy (IS) using F(ab')2 fragments of indium-111-labeled OC 125 monoclonal antibody (specific for CA 125 antigen). The definitive diagnosis of recurrence was made on the basis of histological data obtained at surgery.In all 15 of the patients with recurrence, all three of the imaging methods had false negative results once. In 7 patients, only the IS method had positive results; six of these 7 benefited from a macroscopically total resection of the recurrence. IS was positive and concordant with US and/or CT in 7 further patients. Two of them benefited from a total resection of their recurrence. The usefulness of IS was more evident when serum CA 125 concentration was below 500 U/ml. The absence of recurrence was correctly indicated by IS and CT in 1 case and by IS associated with negative US and CT in 2 other cases. IS and CT were falsely positive in 1 case.Thus, immunoscintigraphy would appear to be an efficient method for detecting a recurrence early when limited involvement can make it possible for the surgeon to achieve total resection. |
