卵巢位于盆腔深部,很难通过常规的体格检查查出其早期阶段的疾病,并且卵巢癌患者早期无典型的临床表现,因此大部分患者确诊时已在晚期,仅有25%的患者在Ⅰ期发现[1]。而Ⅲ、Ⅳ期卵巢癌患者5年生存率则由Ⅰ期时的95%降至20%~25%[2,3]。所以卵巢癌已成为严重威胁妇女生命的肿瘤。 Ovaries in the deep pelvic cavity, it is difficult to detect the early stage of disease by routine physical examination, and early stage of ovarian cancer without typical clinical manifestations, so most of the patients have been diagnosed late, only 25% of patients in stage Ⅰ Found [1]. However, the 5-year survival rates of patients with stage III and IV ovarian cancer are reduced from 95% at stage I to 20% -25% [2,3]. So ovarian cancer has become a serious threat to the lives of women’s tumors.
