Endometrial and Cervical Cancer Treatments

The protocol was designed to examine the biological effects and clinical activity of interferon-beta in patients with platinum/taxane-resistant ovarian cancer.Patients with resistant ovarian and fallopian tube cancers and primary peritoneal carcinoma were treated with recombinant human interferon-beta (Rebif, Serono International) at doses ranging from 6 to 24 million international units (MIU)/day, based on their tolerance to therapy. Levels of IP-10, an interferon-inducible protein, were measured in the serum to evaluate the biological effects of the drug. Also, the peripheral blood mononuclear cells and serum were examined for the induction of previously described novel regulators of interferon-induced death.Eighteen patients were treated, of whom 9 (50%) could be treated at the highest dose level (24 MIU). The major toxicities were fever, chills and fatigue. The median duration of therapy was 6 weeks (range 1-22). No objective responses were observed. IP-10 levels were significantly increased, compared with baseline, at 2, 4, and 6 weeks after initiation of therapy (p < 0.01).Recombinant human interferon-beta produced a definite biological effect in the serum of treated patients, but this outcome was not translated into any clinically observable or meaningful impact on the disease process.
