Neoadjuvant bleomycin, ifosfamide and cisplatin in cervical cancer.

Patients with advanced and bulky early-stage cancer of the cervix have an unfavourable prognosis, which may be improved by initial neoadjuvant, cytoreductive chemotherapy. In a phase II study, coordinated at the West Midlands CRC Clinical Trials Unit, Birmingham, using ifosfamide (IFX) in combination with cisplatin and bleomycin (BIP) in advanced and recurrent cervical cancer, we demonstrated a response rate of 69%. This regimen produces rapid responses with acceptable toxicity and has potential for use as neoadjuvant therapy prior to radical radiotherapy in patients presenting with advanced and bulky early-stage disease. In an initial pilot study of this approach, 13 of 19 patients (68%) with primary inoperable disease showed significant tumour regression prior to radical local radiotherapy. Interim analysis of the first 66 patients entered into a randomized study evaluating the value of this approach has shown complete clinical tumour resolution after radical radiotherapy in 24/32 patients (75%) treated with up to three cycles of BIP prior to radiotherapy vs 19/34 patients (56%) treated with radiotherapy alone. There was no evidence that neoadjuvant chemotherapy enhances the acute toxic effects of pelvic radiotherapy. This approach has the potential for improving the outlook in patients with poor-prognosis primary disease.
