Perioperative Imatinib Mesylate in Treating Patients With Locally Advanced Gastrointestinal Stromal Tumor

February 2, 2015 updated by: Ziyu Li, Peking University
Imatinib mesylate may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Perioperative imatinib mesylate may shrink the tumor and may reduce the chance of relapse after surgery. This phase II trial is studying the effectiveness of perioperative imatinib mesylate in treating patients with locally advanced gastrointestinal stromal tumor.

Detailed Description

Open-label trial in patients with locally advanced GISTs admitted to Department of Surgery, Beijing Cancer Hospital and Institute between April 2010 and May 2013 was carried out prospectively. Patients were planned to be treated with imatinib for duration of 6 months followed by surgical resection. Postoperative imatinib was planned to be administrated for 1.5 years. The primary end point was recurrent free survival (RFS) at 2 years; the secondary end points included objective response rate (ORR), surgical outcomes and drug safety.
