- Description
- Patient 36 from a larger cohort of genotyped patients (n= 78) with imatinib resistant or intolerant gastrointestinal stromal tumors (GISTs) harbored a primary (pre-imatinib treatment) KIT V555_V559 deletion. Following failure of imatinib, the GIST was again genotyped, but no secondary mutations were found. The patient took 50 mg sunitinib per day on a treatment schedule of four weeks on/two weeks off. The patient experienced progressive disease. Time to progression and overall survival were 10 and 108 weeks.
