本文14例无性细胞瘤中,单纯型12例,合并内胚窦瘤1例,伴发性腺母细胞瘤1例。单纯型者的5年存活率占80%以上,合并有其他恶性生殖细胞瘤者的预后较差。无性细胞瘤伴发性腺母细胞瘤者,其性腺母细胞瘤大部分可被取而代之,需仔细寻找,但病人常为46XY 核型,可为此提供线索。本组中,两侧性患者有2例,此提示在保守性外科手术时,对侧卵巢也应作活检. In this article, 14 cases of dysgerminoma, simple type in 12 cases, 1 case of endodermal sinus tumor, 1 case of associated adenoblastoma. Simplex type 5-year survival rate of more than 80%, combined with other malignant germinoma were poor prognosis. Atypical cell tumor associated with adenoblastoma, most of its gonadoblastoma can be replaced, to be carefully searched, but the patient often 46XY karyotype, to provide clues to this. In this group, two patients on both sides of the hint, suggesting that in conservative surgery, the contralateral ovary should also be biopsy.
