摘要
To the Editor：A uterine carcinosarcoma （malignant mixed Mtüllerian tumor [MMMT]） is a rare,aggressive,malignant tumor which demonstrates both malignant epithelial （carcinoma） and mesenchymal （sarcoma） components.[1] MMMTs account for 2-5% of all uterine malignancies.Metastatic progression is uncommon and occurs through hematologic,lymphatic,and intraperitoneal spread.Risk factors for MMMTs include radiation,excessive estrogen exposure,obesity,and nulliparity.The 2-year survival rate for patients with MMMTs is 53% for Stage Ⅰ disease and decreases to 8.5% for Stages Ⅱ and Ⅲ.
