Infected complex renal cysts during crizotinib therapy in a patient with non–small cell lung cancer positive for ALK rearrangement

Abstract: Crizotinib is the first clinically available tyrosine kinase inhibitor that targets anaplastic lymphoma kinase (ALK) and is associated with the development of complex renal cysts. We now describe a 39-year-old woman who developed infected complex renal cysts during crizotinib treatment. After 10 months of such treatment, she presented with a high fever and low back pain. Computed tomography findings were consistent with complex renal cysts and perilesional inflammation. Interventions including cyst drainage an… Show more

“…10 In mice kidneys, c-MET activation pathway decreased during the crizotinib treatment; it would seem to be aparadox. 11 Therefore by inhibiting c-MET pathway, crizotinib might stop the growth of pre-existing cystic lesions and prevent the onset of new renal ones. 9 This suggests that alternative pathways may be involved in cysts onset during the crizotinib treatment.…”

“…Crizotinib has been associated with development of renal cysts [3], [4], [5], however, limited literature is available to describe its progression and imaging features due to novelty of this class of drug. Although crizotinib is used as a targeted selective inhibitor of ALK, it is a multikinase inhibitor of c-MET and ROS1 oncogenic tyrosine kinases.…”
