进展期胃肠间质瘤的合理诊疗策略

Strategies in diagnosis and management for advanced or metastatic gastrointestinal stromal tumor

随着对胃肠间质瘤（GIST）认识的提高。临床上诊断为GIST患者的比例逐年升高。早期GIST行手术完整切除预后良好，而进展期GIST无论是在单纯手术治疗阶段、单纯伊马替尼靶向治疗阶段还是手术联合伊马替尼治疗阶段，手术后再复发、伊马替尼耐药和靶向药物多重耐药等问题仍然是目前治疗的难点。大量的临床证据显示．合理的治疗策略可以改善进展期GIST患者的预后。进展期GIST绝不能单纯认为是内科或者外科疾病，需要包括肿瘤外科、肿瘤内科、病理科、影像科和介入科等多学科协作组的综合诊疗。本文结合目前国内外最新研究进展．基于循证医学证据和笔者经验．提出进展期GIST的合理诊疗策略．以期达到早期发现、初期预防和恰当管理的目标．从而改善患者预后．延长生存期．

With deeper understanding of gastrointestinal stromal tumor （GIST）, more and more patients are diagnosed as GIST. Although the prognosis of early GIST is satisfactory after complete surgical resection, there are still many problems in the treatment of advanced GIST. Variety of treatment options has been used in the treatment of GIST, such as surgery, targeted drug therapy, and surgery plus imatinib therapy. However, post-operative recurrence, imatinib-resistance, muhi-targeted drug resistance are still challenges. Many clinical evidences show that a reasonable management strategy can improve the prognosis of patients with advanced GIST. All the doctors should have a clear mind to carry out appropriate interventions. Advanced GIST should not be simply considered to be either medical or surgical disease, but rather must be systemetically managed by multidisciplinary team approach combining surgical oncology, medical oncology, pathology, and interventional medicine.This review will advocate suitable treatment strategies based on the most recent progresses in systemic treatment for advanced GIST and our clinical experience to achieve early detection, early prevention, proper management, and therefore improve the survival of these patients.
