The records and biopsies of 10 patients with the diagnosis of leiomyosarcomas admitted at the Military Hospital "Dr. Carlos Arvelo" from 1962 to 1991, were reviewed. The sample correspond to 0.47% of all gastro-intestinal tumors. Sixty per cent of tumors were localized in the stomach, 20% in the jejunum, 10% in the duodenum and 10% in the colon. Eighty per cent had pain and 60% had bleeding. Sixty per cent of tumors were low grade leiomyosarcomas and 40% were epithelioid leiomyosarcomas. In eight of nine patients operated, resection was done. The survival range was from six months to 28 years with a median of 12 years. The most important prognostic factor was the extension of the tumor, independently of he histologic type.
对1962年至1991年在“卡洛斯·阿韦洛博士”军事医院收治的10例诊断为平滑肌肉瘤患者的病历和活检进行了回顾。该样本占所有胃肠道肿瘤的0.47%。60%的肿瘤位于胃，20%位于空肠，10%位于十二指肠，10%位于结肠。80%的患者有疼痛，60%有出血。60%的肿瘤为低级别平滑肌肉瘤，40%为上皮样平滑肌肉瘤。9例手术患者中有8例行切除术。生存时间从6个月至28年不等，中位生存时间为12年。最重要的预后因素是肿瘤的侵犯范围，与组织学类型无关。
