title: Phase II study of ifosfamide in cervical cancer.
abstract: Thirty patients with symptomatic, progressive squamous cell carcinoma of the uterine cervix no longer amenable to surgery or radiotherapy were entered in a phase II study of ifosfamide (IFX). Patients were treated with IFX (5 g/m2 iv given over 24 hours) and concomitant mesna (total dose, 9.2 g/m2 iv given over 36 hours) every 21 days. One complete response (duration, 10+ months) and nine partial responses were observed, with an overall median response duration of 6.5 months. The median survival of responding patients was 11 months. Objective response rates for lesions arising in previously irradiated sites (four of 22) were significantly lower than for lesions arising in nonirradiated sites (15 of 28) (P = 0.018). There were two treatment-related deaths: one due to leukopenia-associated infection in a patient with peritonitis and severe central nervous system toxicity and one due to central nervous system toxicity without complicating factors. One other patient developed severe but reversible encephalopathy. In all remaining patients hemorrhagic cystitis and hematological and gastrointestinal toxic effects were predictable and manageable. Treatment was delayed for 1 week due to toxicity on seven of 101 occasions: four of these delays were due to mild, reversible impairment of renal function and three were due to leukopenia. Complete though reversible alopecia occurred in 22 of 30 patients. The results indicate that IFX is active in cervical cancer and deserves further study in this setting.
