Abstract
Institut Georges Lopez-1 (IGL-1) solution is increasingly used for kidney preservation, although little information on outcomes is available. Outcomes of all deceased donor kidneys preserved by IGL-1, University of Wisconsin solution (UW), or histidine-tryptophan-ketoglutarate (HTK) and transplanted in our center (2000-2018) were analyzed. Multivariable analysis for delayed graft function (DGF), functional DGF, estimated glomerular filtration rate (eGFR, CKD-EPI equation), proteinuria, acute rejection, death-censored graft loss, and patient survival were performed. A double robust approach, consisting of propensity score weighting and correction for confounders, minimized the risk of bias. In total, 1943 transplants were included: 234 with IGL-1, 1046 with UW, and 663 with HTK. As IGL-1 was only introduced in 2014, a prespecified sensitivity analysis of 917 kidneys (2010-2018) was performed using the same statistical approach. After weighting, IGL-1 retained a higher proportion of kidneys donated after circulatory death (DCD). IGL-1 was not independently associated with any of the outcomes when compared to UW or HTK. Sensitivity analysis between 2010 and 2018 showed similar results. In this retrospective analysis, using robust methodology to reduce the risk of bias, IGL-1 preservation results in equal outcomes compared to UW or HTK, despite more DCD transplants in the IGL-1 group.

Abstract
Tyrosine kinases are implicated in tumorigenesis and progression, and have emerged as major targets for drug discovery. Tyrosine kinase inhibitors (TKIs) inhibit corresponding kinases from phosphorylating tyrosine residues of their substrates and then block the activation of downstream signaling pathways. Over the past 20 years, multiple robust and well-tolerated TKIs with single or multiple targets including EGFR, ALK, ROS1, HER2, NTRK, VEGFR, RET, MET, MEK, FGFR, PDGFR, and KIT have been developed, contributing to the realization of precision cancer medicine based on individual patient's genetic alteration features. TKIs have dramatically improved patients' survival and quality of life, and shifted treatment paradigm of various solid tumors. In this article, we summarized the developing history of TKIs for treatment of solid tumors, aiming to provide up-to-date evidence for clinical decision-making and insight for future studies.
