Phase II Trial of Neoadjuvant/Adjuvant Imatinib Mesylate (IM) for Advanced Primary and Metastatic/Recurrent Operable Gastrointestinal Stromal Tumor (GIST) – early results of RTOG 0132

摘要

Background:Therapy for gastrointestinal stromal tumors (GIST) has changed significantly with the use of Imatinib Mesylate (IM). Despite the success of this drug in metastatic GIST, disease progression remains a perplexing clinical issue suggesting the need for multimodality management. There have been no prospective studies either evaluating the neoadjuvant use of IM in primary GIST or as a preoperative cytoreduction agent for metastatic GIST.
