Tumor Associated Antigen

In the follow-up of ovarian cancer patients, rising levels of the tumor-associated antigen CA 125 are an indication for immunoscintigraphy. Human anti-mouse antibodies (HAMA) are frequently found after immunoscintigraphy with murine MAb directed against CA 125. Since we observed that patients developing high HAMA-levels in serum remained free of tumor or had stable disease, we examined the cytotoxic activity of peripheral blood lymphocytes (PBL) by a fluorescence-based assay. Our results demonstrate that PBLs of patients with high anti-idiotypic antibodies show an increased cytotoxic activity (by a factor of 4) compared to those of patients with low HAMA levels. The clinical course of the patients after the first injection of murine monoclonal antibody was observed over a period of 1 to 3 years. Improvement or deterioration of patients ‘ clinical condition corresponded with the results obtained by functional analysis. Further investigations concerning the course of cytotoxic activity in HAMA-positive patients will have to clarify HAMA's role in the immune response.
