- Description
- 147 patients with advanced, unresectable GISTs were enrolled onto a randomized, phase II clinical study of imatinib (CSTI571-B2222). Specimens from 43 pretreatment and/or imatinib-resistant tumors were analyzed to identify molecular correlates of imatinib resistance. C809G was observed as a secondary KIT mutation in one patient with secondary imatinib resistance. In vitro, C809G showed imatinib resistance both in isolation and when coexpressed with K642E + N822H (the primary KIT mutations, found on the same allele, for this patient).
