[VIRTUAL] Next generation sequencing of sarcomas: Response to crizotinib in two cases with MET amplification. (ASCO 2021)
Several rare and novel fusions were identified; a sarcoma with TPM4-NTRK3 fusion responded to larotrectinib, while a sarcoma with PML-JAK1 fusion did not respond to ruxolitinib, and a sarcoma with IL7R-BCL2 fusion progressed on venetoclax . NGS profiling led to a targeted therapy with a clinical benefit rate of 12% in this cohort . NGS profiling led to a change in diagnosis in 5% of this cohort . Multi-institutional collaborations to track outcomes of matched therapy would help determine the utility of therapies in rare cancers and unusual alterations.
