卵巢颗粒细胞瘤的诊断和治疗研究进展

卵巢肿瘤种类繁多，而性索间质类肿瘤相对少见，约占卵巢肿瘤的5％，而颗粒细胞瘤（granulosa cell tumot，GCT）是性索间质肿瘤中最常见的一种。GCT呈低度恶性，大多数患者诊断时属手术病理分期Ⅰ期，5年生存率高达90％，但是易远期复发，20年生存率低于50％，近年来，随着人们对GCT认识地不断深入，其诊断和治疗有了一些新的进展。

Research Progress on Diagnosis and Therapy of Ovary Granulosa Cell Tumor

There are plenty of tumors in the ovary,while sex cord-stromal tumors are rather rare,accounting for approximately 5% in the ovarian tumors.Among sex cord-stromal tumors,granulosa cell tumor(GCT) is most commonly seen,which has a relatively lower malignancy,and most patients with this kind of disease have a better prognosis comparing to those with other ovarian carcinomas.But it has a high rate of distant recurrence,and the 20-year survival rate is lower than 50%.In recent years,more and more diagnostic and therapeutic research has been made,with the increasingly deeper discovery and recognition to this disease.
