Characterization of Interchanging Incretin Analogs in Clinical Practice: A Descriptive Report.

Objective: To characterize the tolerability associated with incretin analog interchanges to equipotent or higher strengths based on an interchange process in an adult outpatient setting.

Methods: This was a retrospective chart review of adult patients receiving care through a participating family medicine or endocrinology clinic between January 1, 2022, and November 30, 2022 at a major academic medical center. An incretin analog equivalency table and protocol for interchange was created in response to ongoing shortages and need for therapy adjustments to different medications within the same class.

Cancer Cells Promote Phenotypic Alterations in Hepatocytes at the Edge of Cancer Cell Nests to Facilitate Vessel Co-Option Establishment in Colorectal Cancer Liver Metastases.

Vessel co-option is correlated with resistance against anti-angiogenic therapy in colorectal cancer liver metastases (CRCLM). Vessel co-opting lesions are characterized by highly motile cancer cells that move toward and along the pre-existing vessels in the surrounding nonmalignant tissue and co-opt them to gain access to nutrients. To access the sinusoidal vessels, the cancer cells in vessel co-opting lesions must displace the hepatocytes and occupy their space.
