Safety and efficacy of immune checkpoint inhibitors in patients with pre-treatment reduced left ventricular function.

Aims: Immune checkpoint inhibitors (ICIs) have revolutionized cancer treatment outcomes. However, the response varies across different populations, and their use may lead to life-threatening cardiovascular (CV) events. While pre-treatment reduced left ventricular ejection fraction (LVEF) is considered a marker for high-risk cardiotoxicity and a contraindication for anthracycline and HER2-targeted therapies, there is limited evidence on the safety and efficacy of ICIs therapy in patients presenting with pre-treatment reduced LVEF.

Early Infiltration of Innate Immune Cells to the Liver Depletes HNF4α and Promotes Extrahepatic Carcinogenesis.

Unlabelled: Multiple studies have identified metabolic changes within the tumor and its microenvironment during carcinogenesis. Yet, the mechanisms by which tumors affect the host metabolism are unclear. We find that systemic inflammation induced by cancer leads to liver infiltration of myeloid cells at early extrahepatic carcinogenesis.
