Ninety-Six - Hour Paclitaxel Infusion after Progression during Short Taxane Exposure: A Phase II Pharmacokinetic and Pharmacodynamic Study in Metastatic Breast Cancer
Antineoplastic Agents, Phytogenic
Paclitaxel demonstrates activity against metastatic breast cancer when administered over 96 hours to patients with disease that recently had progressed during short taxane exposure. Delayed paclitaxel clearance and consequent increased toxicity occurred in patients with hepatic dysfunction. The activity observed supports preclinical data that suggest variability in efficacy and resistance patterns to paclitaxel based on duration of exposure.
