PHASE-II STUDIES OF IFOSFAMIDE ALONE AND IN COMBINATION IN CANCER OF THE CERVIX

A series of phase II studies using ifosfamide (IFX) as a single agent and in combination with cisplatin and bleomycin (BIP) in advanced and recurrent cervical cancer have been coordinated at the West Midlands CRC Clinical Trials Unit (Birmingham, UK). The aims of these studies were to identify single agents and combination regimens that may be of value for palliation and have potential for use as neoadjuvant and adjuvant therapy at the time of primary treatment. A total of 79 patients with disease non-amenable to radical local therapy were treated with single-agent IFX or the BIP combination. In 30 patients treated with single-agent IFX, 10 objective responses (30%) were seen, with 1 complete response. In 49 patients treated with BIP, 34 objective responses (69%) were seen, with 10 complete responses (20%). Toxicity included alopecia, nausea and vomiting, myelosuppression, infection, reduction in renal function and disturbance of consciousness. These data indicate that IFX is highly active in cervix cancer and, in combination with bleomycin and cisplatin, can be used for effective palliation and cytoreduction in >70% of patients. IFX-containing regimens have potential for use as neoadjuvant and adjuvant therapy in patients at high risk of recurrence with conventional treatment. These hypotheses are currently being tested in prospective randomised trials. © 1990 Springer-Verlag.
