Pathologic Complete Response to Neoadjuvant Imatinib of a Gastric Stromal Tumor with Concomitant Mutations in : A Case Report and Literature Review

Abstract

Key Clinical Message: We report the first case of pathologic complete response (pCR) to neoadjuvant imatinib in a gastric stromal tumor harboring mutations in both exons 11 and 9. The significance of this co-occurrence is unknown and might increase the responsiveness of gastrointestinal stromal tumors (GISTs) to imatinib.

Abstract: pCR of GIST to neoadjuvant imatinib is rare. We report a case of pCR to neoadjuvant imatinib in a gastric stromal tumor that harbored co-occurrence of multiple mutations in exons 11 and 9. This co-occurrence in exons 9 and 11 is the first to be reported in the English literature.
