OUTLINE: This is a dose escalation study of irinotecan. Patients receive irinotecan IV concurrently with paclitaxel IV weekly. Patients demonstrating stable disease or partial or complete clinical response continue with treatment as long as dose limiting toxicities are not observed and adequate performance status is maintained. Cohorts of 3 patients receive escalating doses of irinotecan until the maximum tolerated dose is determined or 150 mg/m2 is reached.
