Brief summary: This study is intended to investigate the clinical efficacy of TTV vaccine combined with PD-1/PD-L1 inhibitor in the treatment of relapsed and refractory advanced solid tumours from a clinical perspective.

Detailed description: The innovative invention of Tumour Treatment Vaccine (TTV) has been verified in previous studies that the TTV vaccine can play a good role in enhancing the anti-tumour effect of immune checkpoint inhibitor therapy, and the tumour suppression rate of combined anti-PD-1 inhibitor reaches 75.96%. Therefore, this study is intended to investigate the clinical efficacy of TTV vaccine combined with PD-1/PD-L1 inhibitor in the treatment of relapsed and refractory advanced solid tumours from a clinical perspective.
