Abstract: Objective Gastrointestinal stromal tumor(GIST)is a rare mesenchymal tumor from gastrointestinal tract,and surgery remains the only curative treatment.In order to improve the outcome of surgical treatment,reduce the risk of surgery,and increase the quality of life,preoperative imatinib(IM)treatment for GIST is investigated.Methods We retrospectively studied the multidisciplinary team model treatments for 8 GIST cases receiving preoperative IM treatment.The cases were prescribed IM of 400mg daily for 12 to 40 weeks and extensively followed until surgery was considered feasibleg.The clinical significance and safety profile were analyzed.Results Partial responsive rate was 62.5% in this study.There was no intolerable sever adverse effects by IM preoperative treatment.All the cases received R0 dissection,with no intraoperative tumor rupture.The postoperative recovery was satisfied.Conclusion IM preoperative treatment brings significant clinical benefit to large stomach GISTs and cardiac region GISTs.The preoperative treatment should be monitored carefully under a multidisciplinary team.Preoperative IM treatment is an evocative treatment strategy for high risk GIST.
