[The conversion therapy for unresectable gastric cancer].

The unresectable gastric cancer refers to be unable to accept radical gastrectomy because of advanced stage, which is mainly treated with adjuvant chemotherapy, and obtains only poor prognosis in the past. In recent years, however, some scholars found that the unresectable gastric cancer cases which were treated with systematic chemotherapy, radiochemotherapy, interventional therapy, hyperthermic intraperitoneal peroperative chemotherapy and so on, could be converted into resectable (radical D2 gastrectomy) cases successfully, and their survival time and quality of life are promoted significantly. The conversion therapy for unresectable gastric cancer provides a novel surgical strategy for the comprehensive treatment of part of the advanced gastric cancer patients.
