Focal Update on Immunotherapy and Liver Transplantation in the Era of Transplant Oncology

Transplant oncology is an expanding area of cancer therapy that specifically emphasizes the use of liver transplantation (LT) as the preferred treatment for patients with manageable, but unresectable, tumors. The management and optimization of overall survival strategies, accompanied by an arguably decent quality of life, have been at the forefront of liver oncology treatment, as a plurality of all primary liver cancers are identified as either hepatocellular carcinoma (HCC) or cholangiocarcinoma (CCA), which are classified as highly aggressive malignancies and frequently remain asymptomatic until they progress to advanced stages, rendering curative procedures, such as resection, impractical. This has led to an increase in utilization of neoadjuvant interventions conducted prior to surgery, which has yielded favorable outcomes. Though this treatment modality has prompted further investigations into the efficacy of immune checkpoint inhibitors (ICPIs) as standalone treatments and in combination with locoregional treatments (LRTs) to bridge more patients into curative eligibility. This multidisciplinary methodology and treatment planning has seen multiple successful trials of immunot
