Core Tip
Core Tip: Cryoablation exerts a dual and exploitable immunomodulatory effects in hepatocellular carcinoma. Acting as an in situ vaccine, cryoablation induces immunogenic cell death and simultaneously triggers a transient immunosuppressive effect. This duality is strategically used by combining cryoablation with immune checkpoint inhibitors to remodel the immunosuppressive “cold” tumor microenvironment. Ablation completeness, technical parameters, and host immune status are critical determinants of therapeutic success. In order to fully achieve its clinical potential, future initiatives ought to be directed towards overcoming the difficulties of patient stratification and treatment sequencing by developing predictive biomarkers and optimized combination regimens.
