本文报告11例子宫恶性中胚叶混合瘤的临床、病理研究。无特殊临床征象。3例死于本病,7例术后存活1年半到8年。7例肿物为息肉状。镜下2例组织类型为同质型,9例为异质型。3例生存7年以上者,瘤团周围有明显的间质反应(淋巴细胞浸润)。我们认为:肿瘤的组织类型对预后似乎无明显影响,而间质反应与预后却有重要关系。此外,手术切除配合化疗可能对预后有所裨益。 This article reports 11 cases of uterine malignant mesodermal mixed tumor clinical and pathological studies. No special clinical signs. 3 patients died of this disease, 7 patients survived 1 year and a half to 8 years. Seven cases of polypoid tumor. Microscope in 2 cases of tissue type is homogeneous, 9 cases of heterogeneous. Three patients who survived for more than 7 years had significant interstitial (lymphocytic infiltration) around the tumor mass. We think: the type of tumor tissue seems to have no significant effect on prognosis, while the interstitial response and prognosis have an important relationship. In addition, surgical resection combined with chemotherapy may be of some benefit to the prognosis.
