Combine TACE and Autologous Tcm Immunotherapy Versus TACE Alone for HCC With MVI After Radical Resection

A Single-center, Open-label, Exploratory Trial of Autologous Immunotherapy for Hepatocellular Carcinoma (HCC) With Microvascular Invasion (MVI) After Radical Resection

The purpose of this study is to assess the efficacy and safety of combining autologous Tcm immunotherapy and TACE in HCC patients with MVI after radical resection. Patients will be assigned either to the experimental arm to receive autologous Tcm immunotherapy and TACE or to the active comparator (TACE alone).

Study Overview

Detailed Description

Hepatocellular carcinoma (HCC) is one of the common cancer worldwide, which is the third cause of cancer related deaths. Radical hepatic resection remains the main treatment for hepatocellular carcinoma, the 5-year survival rate of HCC after surgery was 60-70%. Unfortunately, HCC is prone to postoperative recurrence that more than 50% of patients relapse within 2 years, which has become the key to restrict the therapeutic effect of hepatocellular carcinoma. Microvascular invasion (MVI) is one of the main risk factors for poor prognosis in HCC.

Autologous cell immunotherapy is to collect patient's own immune cells and then given back to the patient after amplified in vitro that can improve the anti-tumor immune response. Tcm (central memory T cells) are effective anti-tumor immune cells that exhibit the long-term survival and self-renewal capacity in vivo. Autologous Tcm immunotherapy combining chemotherapy, surgery or radiotherapy would effectively prolong survival period, prevent tumor recurrence and metastasis, then improve quality of life in patients.
