Percutaneous microwave ablation or intratumor injection of drug-eluting beads to destroy cancer cells to release tumor-specific antigens~Intratumor injection of type A/C CpG-ODN with or without infusion of CAR-T cells secreting scFv against OX40~Assessing side effects and therapeutic efficacy after the combined treatments
To study the safety and clinical effects of intratumor injecting CpG-ODN and in situ release of tumor antigen by interventional ablation or drug-eluting beads to treat advanced solid tumors.
