胃平滑肌肉瘤的治疗有肿瘤局部切除,局部扩大切除、胃次全切除或全胃切除不等,为了比较根治性切除和广泛局部切除的疗效,作者分析了 Mayo 临床中心于1964～1988年手术切除53例胃平滑肌肉瘤的资料。按肿瘤细胞镜检每10个高倍镜视野可见有丝分裂相1～3个、3～6个、6个和6个以上者分别列为1、2、3和4级,后2级细胞丰富、非典型明显,并有坏死。取肿瘤侵犯邻近器官、肿瘤大干5cm、分级高为危机因素,无上述危机因素者列为0期肿瘤,其
The treatment of gastric leiomyosarcoma includes local tumor resection, partial enlarged resection, subtotal gastric resection, or total gastrectomy. To compare the curative effect of radical resection and extensive local resection, the author analyzed the surgical resection of Mayo Clinic Center from 1964 to 1988. 53 cases of gastric leiomyosarcoma. The number of mitotic phases 1-3, 3-6, 6 and 6 of each mitochondrial phase was classified into 1, 2, 3, and 4 grades by tumor cell microscopic examination, and the second grade cells were rich in SARS. The type is obvious and there is necrosis. The tumors invaded adjacent organs, the tumor was 5cm thick, and the graded high was a crisis factor. Those without the above crisis factors were classified as stage 0 tumors.
