Ischémie digitale sous gemcitabine, Ã propos de deux cas

A 73-year-old man with an urothelial carcinoma treated with gemcitabine and carboplatinium and an 84-year-old man with a mesothelioma treated with gemcitabine alone developed digital ischemia. In the first patient, the ischemia involved all fingers except the thumbs during the second cycle of treatment. The ischemia developed during the first cycle in the second patient and involved the right major and ring fingers. In the literature, gemcitabine vascular toxicity is probably potentialized by platinium salts. Several nosological entities occur simultaneously. The most widely described involve isolated digital ischemia for doses to the order of 3000 mg, and a hemolytic and uremic thrombotic microangiopathy for gemcitabine doses above 10,000 mg. The vascular toxicity of platinium salts is not dose-dependent. In these two patients, the clinical course was favorable with interruption of the chemotherapy, treatment by iloprost and aspirin.
