Tumour marker CA125 levels in a variety of benign and malignant conditions.

: The levels of tumour marker CA125 were established in 515 patients with a variety of benign and malignant conditions. With a specificity of 60.3% and an overall sensitivity for malignant tumours of 54% (extra-ovarian serous papillary carcinomas 100%), it is the most reliable tumour marker at present available for epithelial ovarian cancer and is of considerable value in the management of this condition when considered in conjunction with other clinical measurements.
