Ovarian cancer accounts for the death of over 100,000 females every year and is the most lethal gynecological malignancy. Low-grade serous ovarian carcinoma (LGSOC) and high-grade serous ovarian carcinoma (HGSOC) have been found to represent two distinct entities based on their molecular differences, clinical course, and response to chemotherapy. Currently, all ovarian cancers are staged according to the revised staging system of the International Federation of Gynecology and Obstetrics (FIGO). Imaging plays an integral role in the diagnosis, staging, and follow-up of ovarian cancers. This review will be based on the two-tier grading system of epithelial ovarian cancers, with the main emphasis on serous ovarian cancer, and the role of imaging to characterize low-grade vs high-grade tumors and monitor disease recurrence during follow-up.
卵巢癌每年导致超过10万名女性死亡,是最致命的妇科恶性肿瘤。基于分子差异、临床病程及对化疗的反应,低级别浆液性卵巢癌(LGSOC)和高级别浆液性卵巢癌(HGSOC)已被发现代表两种不同的实体。目前,所有卵巢癌均根据国际妇产科联盟(FIGO)的修订分期系统进行分期。影像学在卵巢癌的诊断、分期及随访中发挥着不可或缺的作用。本综述将基于上皮性卵巢癌的两级分级系统,主要侧重于浆液性卵巢癌,以及影像学在鉴别低级别与高级别肿瘤及随访期间监测疾病复发方面的作用。
