Pilot study of regional, hepatic intra-arterial paclitaxel in patients with breast carcinoma metastatic to the liver.

Background: Approximately 25% of patients with metastatic breast carcinoma develop hepatic involvement during the course of their disease that further affects their survival. Systemic paclitaxel is safe and has demonstrated good antitumor activity against breast carcinoma. The objective of this prospective study was to determine the safety and antitumor activity of hepatic intra-arterial paclitaxel therapy.
