Serum copper levels in carcinoma of ovary and cervix

The role of serum copper level (SCL) as a diagnostic and prognostic tool in genital tract malignancies was evaluated. SCL was employed as a marker for response to treatment (surgical/radiotherapy). 129 women attending gynaecology outpatient department or admitted in the gynecology ward were studied. Of these 77 patients in the disease (study) group were proven cases of genital tract malignancies and 52 served as controls. Outcome measures studied were: SCL levels estimated before initiation of any treatment i.e. surgery/radiotherapy; thereafter, at two weeks after completion of treatment. Follow up of the study subjects was done between 4-8 weeks and 8-10 weeks, when the patients were evaluated for any recurrence of disease and SCLs were also estimated. Kruskal-Wallis one-way analysis of variance determined whether values varied significantly among the different groups studied. Mean SCLs were found to be significantly elevated in cases of Ca ovary (n = 15), early CaCx (n = 14) and late CaCx (n = 48), as compared to the control group, comprising of women with no signs and symptoms of malignancy (n = 52). SCLs decreases significantly (P < 0.001) after treatment of Ca ovary and CaCx. These results indicate a possible clinical usefulness of estimating serum copper levels in women with genital tract cancer and suggest a role for SCL in the evaluation of the disease activity and as a prognostic tool in the management of genital malignancies.
