Autologous Tumor-Infiltrating Lymphocyte Infusion plus Anti-Programmed Cell Death Protein 1 Therapy to Cure Advanced...

Adoptive cell therapy derived from autologous tumor-infiltrating lymphocytes (TILs) has demonstrated promising therapeutic efficacy in several cancers. However, its possible synergistic effects with anti-PD-1 therapy in advanced hepatocellular carcinoma (aHCC) remain unexplored. This study aimed to investigate the efficacy of TIL infusion combined with anti-PD-1 therapy for aHCC.

Referring to the current protocol of our clinical trial (NCT03658785), 2 patients with HCC at BCLC stage C were enrolled to receive autologous TIL infusion combined with anti-PD-1 therapy. They underwent unplanned palliative tumor resection to alleviate pain caused by tumor rupture prior to receiving TIL infusion plus anti-PD-1 therapy. Long-term outcomes and treatment-related adverse events were evaluated. Throughout the entire treatment process, both patients experienced only mild symptoms. Notably, both patients achieved complete responses to the treatment and have remained tumor-free for 2 and 4 years, respectively.

Autologous TIL infusion combined with anti-PD-1 therapy is a safe and feasible strategy for patients with aHCC. Palliative hepatectomy with maximal tumor burden reduction may significantly improve its efficacy and even results in cure for aHCC patients.
