OBJECTIVES:

• Determine the antitumor activity of DX-8951f in women with advanced or recurrent squamous cell carcinoma of the cervix.
• Evaluate the quantitative and qualitative toxic effects of this regimen in these patients.
• Evaluate the pharmacokinetics of this regimen in these patients.

OUTLINE: This is a multicenter study.

Patients receive DX-8951f IV over 30 minutes daily for 5 days. Courses repeat every 21 days in the absence of disease progression or unacceptable toxicity.

Patients are followed every 3 months until death.
