Serum copper level in ovarian carcinoma

Serum copper levels (SCL) were determined before any diagnostic procedure was performed or treatment given in 40 women admitted for the investigation of a pelvic mass and, later, in those patients with ovarian carcinoma after chemotherapy and before a second-look operation was performed. Patients with ovarian carcinoma were found to have significantly higher SCL than patients with benign ovarian lesions. A SCL of 150 micrograms/dl clearly separated patients with a pelvic mass on the basis of ovarian carcinoma and those with benign noninflammatory pelvic lesions. The same SCL of 150 micrograms/dl separated patients with ovarian carcinoma that responded to chemotherapy and those with residual disease. It is suggested that SCL be included as a member of the screening panel of biologic tumor markers in general and in ovarian carcinoma in particular.
