• But: KIT needs to be phosporylated to start its signaling cascade– Absence of phosphorylation of KIT in uterine LMS, probably
not involved in tumorigenesis and not likely to be a target for anti-tyrosine-kinase drug therapy (Serrano et al., Clin Cancer Res 2005;11:4977-8)
• But: tumors with mutations in exon 11 are likely to respond– Lack of mutations in uterine sarcomas (Rushing et al., Gynecol
