【摘要】 作者报道经手术切除的胃肠道平滑肌肉瘤２６例，结果发现其区域淋巴结转移率为１１．５％，小肠平滑肌肉瘤较胃平滑肌肉瘤分化差，且易发生穿孔（４５．５％），结果提示本病部分病例需行局部淋巴结清扫是必要的。小肠平滑肌肉瘤预后较差的原因可能是：①病理分化不良者多；②易发生肿瘤穿孔致腹腔内播散。表阿霉素化疗可能对本病有一定疗效。更多还原

【Abstract】 cases of gastrointestinal leiomyosarcomas undergoing surgical resection were reported.The results showed that the rate of matastasis in its regional lymphaden was 11.5%,the pathological differentiation of small intestinal leiomyosarcoma was worse than that of gastric leiomyosarcoma and more likely to have intestinal perforation too(45.5%).These findings suggested that regional lymphotomy in some cases with this disease was necessary.The prognosis of intestinal leiomyosarcoma was worse than that of gastric leiomyosarcoma.The reason may be①worse differentiation and②easier perforation and spreading in abdomen in more cases of intestinal leiomyosarcoma.Chemotherapy by pharmorubicin may have some beneficial effects.更多还原
