Congratualations on Prof. XIA Tian's team for Paper Publication

Sep 17, 2021

The "Journal of Clinical Surgery" of the Chinese Medical Association issued an online publication co-authored by one of AIA's professors, XIA Tian. The paper is entitled "Clinical application of autologous tumor infiltrating lymphocytes combined with anti-PD-1 antibody in the treatment of advanced hepatocellular carcinoma", conducted by XIA Tian's team (AIA), and HUANG Zhiyong's team from the Department of Hepatobiliary Surgery, Tongji Hospital, Tongji Medical College, HUST.


To study the safety and efficacy of clinical application of autologous tumor infiltrating lymphocytes (TIL) after in vitro amplification,in combination with anti-PD-1 monoclonal antibody for the treatment of advanced hepatocellular carcinoma (HCC). Methods: The patients with postoperative recurrence or extrahepatic metastasis that are not operable were selected for the study.TIL was isolated from the tumor samples obtained through local resection under laparoscopy, and TIL was amplified up to 2x109 cells and administered intravenously to the patients. After TIL infusion, anti-PD-1 monoclonal antibody injection was followed every 21 days, and IL-2 was continuously injected to maintain the activity of TIL for two weeks, and the adverse effects and treatment efficacy were evaluated. Results: TIL was successfully isolated, amplified, and administered in 4 patients with advanced liver cancers. All 4 patients showed good tolerance and minor adverse effects. At present, the median follow-up period was 7.5 months,2 patients are under observation, one with lung metastatic lesion disappearing and the other with adrenal metastatic lesion partially necrotizing. The other 2 patients died due to high tumor load and advanced stage of tumor, and their survival time was 3 months and 6 months, respectively. Conclusion: TIL amplification and reinfusion combined with anti-PD-1 monoclonal antibody are safe and feasible in the treatment of advanced HCC, and the long-term efficacy requires further studies. Application of TIL amplified in vitro combined with anti-PD-1 monoclonal antibody is likely a hopeful new therapy for HCC.
