Popis: In published trials, CA125 has been utilized to trigger ultrasound examination for the early detection of ovarian cancer. Although serum CA125 levels can be elevated prior to clinical detection of ovarian cancer, only approximately half of patients with stage I disease will have an abnormal value. A combination of CA125, macrophage colony-stimulating factor (M-CSF) and the mucin marker OVX1 will detect >95% of stage I patients, but it is not known whether the markers can be elevated prior to clinical detection of the disease. A postmenopausal patient was found to have small unilocular bilateral cystic adnexal lesions during an abdominal ultrasound examination. No pelvic abnormality could be palpated. Serum levels of the CA125 antigen were within the normal range. Progressive ultrasound changes prompted a laparotomy 11 months later, and the diagnosis of a stage IC serous cystadenocarcinoma of the ovary was established. A retrospective analysis of stored serum samples revealed that this patient had elevated serum levels of M-CSF and OVX1 at the time of the original ultrasound scan. Interpreted within the context of a potential screening strategy for ovarian cancer, these data illustrate that either or both of these tumor markers and/or ultrasound could have identified this ovarian cancer many months prior to the actual diagnosis, while the disease was at an early stage.
