FaFEC: a novel regimen for advanced ovarian cancer

A palliative combination chemotherapy regimen (FaFEC) was developed for patients with relapsed epithelial ovarian cancer in particular patients relapsing after, or ineligible to enter, phase II trials, usually due to lack of evaluable disease. Forty-six patients were enrolled. Patients had received a mean of 2.3 previous drug regimens and nine (19%) had intestinal obstruction at the start of FaFEC. The majority of patients were inevaluable by WHO criteria so objective response data was obtained from serial serum CA125 evaluations. A serological response was demonstrated in 8/44 (18%). The responders included 6/27 women who had a prior relapse-free interval of less than 3 months, four who were resistant to platinum chemotherapy and three patients who had previously received paclitaxel. The major (WHO grade 3/4) toxicities included leucopenia (six patients), anemia (three patients), thrombocytopenia (two patients), nausea and vomiting (four patients) and severe infections (five patients). Following FaFEC the median time to failure was 0.48 years and the median survival was 0.66 years. FaFEC was effective in this group of very poor prognosis patients. The serological response rate of 18% is noteworthy considering the multiple prior treatments that patients had received and the short treatment free intervals. FaFEC may be useful second line therapy in epithelial ovarian cancer patients ineligible for phase II studies and should be considered for a randomized comparison with paclitaxel.
