...Patients with confirmed ALK fusion proteins, ALK mutations, ALK amplification (defined as greater than 4-fold increase in the ALK signal number as compared to reference signal number on chromosome 2q arm) or MET proto-oncogene, receptor tyrosine kinase (MET) mutation or amplification; testing to confirm the presence of ALK fusion proteins, ALK mutations, ALK amplification or evidence of MET mutation or amplification for eligibility purposes must be performed as a Clinical Laboratory Improvement Act (CLIA)-certified assay; ALK immunohistochemistry can be used as a surrogate for fluorescent in situ hybridization (FISH) for patients with inflammatory myofibroblastic tumors (IMT) or ALCL...

The patient was enrolled in the UNICANCER-sponsored AcSé crizotinib trial (NCT02034981), designed to give an access to crizotinib for patients with tumors harboring a genomic alteration on one of the biological targets of the drug...In metastatic pRCC with a MET amplification, crizotinib maybe a potential met-inhibitory therapeutic option.
