Abstract

BACKGROUND: The new tumor-associated mucin assay, cancer-associated serum antigen (CASA), was assessed with the CA 125 assay for use in the management of patients with epithelial ovarian cancer. METHODS: CASA and CA 125 were assessed retrospectively for use in (1) monitoring 28 patients with Stage 3 or 4 ovarian carcinoma during therapy, (2) predicting the outcome of 41 second-look laparotomies (SLL), and (3) predicting the survival outcome by measuring these levels after surgery but before chemotherapy in 65 patients with Stage 3 disease. RESULTS: Of 20 patients with recurrence after an initial response, the presence of CASA levels detected recurrence in 65% before clinical detection; CA 12..
