Adjuvant PD-1 Inhibitor for Patients With Early-stage Hepatocellular Carcinoma Following Microwave Ablation
Trial Parameters
Brief Summary
For early-stage hepatocellular carcinoma, i.e. Barcelona Clinical Liver Cancer Stage 0, ablation is the standard treatment with a comparable prognosis and less risk of ablation compared with liver resection. However, ablation is demanding on the surgeon and patients often face early recurrence if ablation is not complete. Therefore, it is necessary to find reasonable adjuvant treatment to consolidate the effect of microwave therapy.
