本文报告21例5年以上随访,资料齐全的胃平滑肌肿瘤。按随访结果分为生存组(13例)和死亡组(8例),就两组分别统计巨检和镜检结果,进行分析。结合他人报告,建议诊断胃平滑肌肉瘤的形态学标准为:①幼稚瘤细胞,②非上皮型瘤细胞凝固性坏死,③核分裂相2个以上/10HPF,④瘤细胞重度异型。仅具上述一项者,判断为低度恶性;两项以上者,则为肯定恶性。良、恶性模楞两可者,若肿瘤直径大于10cm、边缘浸润性生长、瘤细胞边界清楚、排列极向紊乱、肿瘤在胃体部、与周围组织粘连,应考虑为边界恶性。
This article reports 21 cases of more than 5 years follow-up, complete data of gastric smooth muscle tumors. According to the follow-up results were divided into survival group (13 cases) and death group (8 cases), the two groups were statistically significant and microscopic examination results were analyzed. Combined with other reports, the proposed diagnosis of gastric leiomyosarcoma morphological criteria are: ① naive tumor cells, ② non-epithelial tumor cell coagulation necrosis, ③ mitotic phase more than 2 / 10HPF, ④ tumor cells atypia. Only one of the above, to determine the low degree of malignancy; two or more, is certainly malignant. Both benign and malignant modalities, if the tumor diameter is greater than 10cm, the edge of the infiltration of growth, tumor cell boundaries clear, the arrangement of polar disorders, the tumor in the gastric body, adhesions with the surrounding tissue should be considered borderline malignant.
