[Renal failure and renal symptoms associated with molecular targeted therapies in oncology].

"Targeted therapies and pathophysiological mechanisms of proteinuria Targeted therapy represents a promising therapeutic approach for patients with diverse cancers and has enabled significant development in medical oncology. This new class of anticancer drugs includes antibodies, fusion-proteins and receptor tyrosine kinase inhibitors among others. Depending on their molecular targeting, side effects can affect multiple organs, especially the kidney. Antiangiogenic agents inhibit the VEGF/VEGFR pathway resulting in reduction of nitric oxide production and alteration of podocytes function, which causes hypertension and proteinuria. EGFR inhibitors are responsible of electrolytic disorders. Hereby, we synthetized the current knowledge on renal toxicities on main molecular targeted therapies. Toxicities management is mainly based on clinical and biological monitoring, which can lead to drug withdrawing or dose adaptation."
