Association Between Galectin-3 Levels and Outcomes in Patients With Renal Cell Carcinoma, Transitional Cell Carcinoma , Non Small Cell Lung Cancer, and Hepatocellular Carcinoma, Treated With PD-1/PDL-1 Inhibitors

1. Background and Rationale:: Galectin-3 (Gal-3) is a β-galactoside-binding protein involved in various biological processes, including cell proliferation, apoptosis, adhesion, and immune regulation. In cancer, Gal-3 promotes tumor progression by enhancing cell survival, metastasis, and angiogenesis. Additionally, Gal-3 can upregulate Programmed Death-Ligand 1 (PDL-1) expression on cancer cells, contributing to immune evasion. PDL-1, an immune checkpoint protein, binds to its receptor PD-1 on T cells, inhibiting their activity and allowing cancer cells to escape immune detection. The interaction between Gal-3 and PDL-1 creates an immunosuppressive tumor microenvironment, reducing the efficacy of PDL-1 inhibitor therapies. Gal-3 drives the inflammatory response and can worsen the inflammation based side effects of PD-1/PDL-1 inhibitos. Understanding this interplay is crucial for optimizing treatments and improving patient outcomes in cancer immunotherapy. The present study employs the FDA-approved, automated Architect system, initially used in cardiology, to ensure high accuracy and consistency in Gal-3 measurement. This method represents a significant advance over traditional manual ELISA kits, aiming to standardize and reproduce results across the patient cohort and to optimize the application of XGAL-3 apheresis based on robust data. The study results can help optimize the use of the XGAL-3 therapeutic apheresis as an adjuvant treatment to enhance the efficacy and r…
