[Significance of immunosuppressive acidic protein in the diagnosis and follow-up of patients with ovarian cancer, in particular as a marker for chemotherapeutic effects].
Serum immunosuppressive acidic protein (IAP) was determined in patients with ovarian cancer and was examined as a marker for ovarian cancer when, chemotherapy in particular, was applied. Samples were sera obtained from 68 ovarian cancers, 74 benign ovarian tumors, 54 cervical cancers, 57 uterine myomas and 88 healthy controls. Elevated levels of IAP were found in 89.5% of patients with ovarian cancer and this high positive ratio was not affected by tumor histologic features. The measurement of the serum IAP level is useful for the initial diagnosis of ovarian cancer because of low false positive rates (8.1%) in benign ovarian tumors and high positive rates even in the early stage of ovarian cancer. Serial determinations of serum IAP levels were well correlated with the response to the treatment (chemotherapy in particular) and the prognosis of cancer patients, even in the case of patients with leucocytopenia induced by the intensive chemotherapy. In case of recurrent patients (whose lesions were observed in the intraperitoneal space), IAP values tended to increase earlier than other conventional tumor-derived markers. Therefore, IAP may also be a useful follow-up marker for patients with ovarian cancer (particularly, for the early detection of recurrence).
