Brief Summary:

Intrahepatic cholangiocarcinoma (ICC) is one of the most common liver malignancies. Surgical treatment is the first choice. However, for patients without surgical indications, the benefits of conventional chemoradiotherapy are limited. CART is one of the fastest developed treatments in recent years. MUC-1 CART can target abnormal glycosylation of MUC-1 and then killing tumor specifically. Here, investigators intend to evaluate the safety and efficacy of MUC-1 CARTin intrahepatic cholangiocarcinoma.

Intrahepatic Cholangiocarcinoma

Biological: MUC-1 CART cell immunotherapy

Detailed Description:

Investigators chose MUC-1 positive intrahepatic cholangiocarcinoma patients with one measurable lesion at least. After general assessment, MUC-1 CART treatment was given to the participants. Objective remission rate, disease control rate, duration of overall response, progression-free survival, overall survival, drugs related side effects and other endpoints events were recorded and analyzed, to assess the MUC-1 CART could or couldn't effectively control the progress of intrahepatic cholangiocarcinoma.

Arms and Interventions

Arm

Experimental: MUC-1 CART

Patients are given fludarabine and cyclophosphamide as pretreatment before MUC-1 CART immunotherapy. After treatment, specific antibodies, CART cells and serum levels of cytokines will be assessed.

Intervention

Biological: MUC-1 CART cell immunotherapy

After fludarabine and cyclophosphamide pre-chemotherapy，MUC-1 CART immunotherapy is given. A decent interval later, levels of specific antibodies, CART cells and serum cytokines will be assessed.
