子宫内膜浆液性乳头状癌(uterine papillary serous carcino-ma,UPSC)是Ⅱ型子宫内膜癌中恶性度较高的1种亚型,其细胞分化差,易发生深肌层浸润、脉管侵犯和远处转移,发病率虽占子宫内膜癌的1%～10%,但在子宫内膜癌治疗失败病例中UP-SC占了近一半,其死亡人数占子宫内膜癌患者死亡人数的39%[1,2],整体存活率(overall survival,OS)仅为18%～27%。
Endometrial serous papillary carcinoma (uterine papillary serous carcinomas, uterine papillary serous carcinomas (UPSC)) is a type II endometrial cancer with higher malignant subtype, its poor cell differentiation, prone to deep myometrial invasion, vascular Invasion and distant metastasis, although the incidence of endometrial cancer incidence of 1% to 10%, but in the failure of endometrial cancer treatment UP-SC accounted for nearly half of the deaths of patients with endometrial cancer deaths Of 39% [1,2], the overall survival (overall survival, OS) was only 18% to 27%.
