45例胃肠道平滑肌肉瘤的临床病理分析

Clinic Pathological Study Analysis of 45 Case Reports of Leiomyosarcoma of Stomach and Bowels

报告了４５例胃肠道平滑肌肉瘤的组织学观察，部分病例作了特殊染色、免疫组化染色及电镜。研究结果揭示：单凭某项甚至几项指标来判定胃肠道高分化低度恶性平滑肌肉瘤往往是不可靠的，必须综合分析肿瘤大小、眼观分型、细胞密度、细胞形态、细胞分化程度和细胞核形态、核分裂数、肿瘤组织继发病变、生长方式和转移情况，再结合临床方能作出较为可靠的诊断。

The pahtological changes of 45 cases of leiomyosarcoma were reported.Some of them were examined with special staining immunohistochemical staining,and electric microscope.The study showed that it is not reliable to make diagnosis of highly divided,lowly malignant leiomyosarcoma of stomach and bowels just by one or even several indexes.It is necessary to integrate and analyse all the data before making final diagnosis,such as size, type,site,metastasis secondary pathological changes of leiomyosarcoma,density, morphology, shape,differentiation of cells, shape, amount of nucleoli, and other clinical data.
