Hepatic Artery Infusion Pump for NPC Liver Metastases

A retrospective clinical trial to study the safety and effectiveness of hepatic arterial infusion (HAI) in treating patients who have nasopharyngeal carcinoma metastatic to the liver. Hepatic-direction drug administration improves the control power for intra-hapatic lesions.

OBJECTIVES:

I. Determine the safety and toxicity of hepatic arterial infusion with gemcitabine, floxuridine and dexamethasone in combination with standard treatment (radiotherapy and systemic chemotherapy) in patients with nasopharyngeal carcinoma metastases to liver.

II. Determine the objective response of intrahepatic lesions of patients treated with this regimen.

III. Determine the median survival time or overall survival time in patients treated with this regimen.

OUTLINE: This is a single-center retrospective study.

Patients receive DSA-guided implantation of HAI catheter system. HAI is initiated the next day. Gemcitabine intra-arterially for 30 minutes on day 1,8, floxuridine, dexamethasone intra-arterially continuously on days 1-14. Treatment repeats every 3 weeks in the absence of serious technical catheter-related problems, progression of intrahepatic lesions or unacceptable toxicity. Standard treatment of NPC, including radiotherapy and chemotherapy (induction chemotherapy, concurrent chemotherapy and adjuvant chemotherapy) was performed as desired.

Patients are followed every 2 HAI cycles or when necessary.
