目的：探讨卵巢成熟囊性畸胎瘤恶变的治疗方法及预后。方法：对２０年卵巢成熟囊性畸胎瘤恶变１１例进行回顾性分析。结果：卵巢成熟囊性畸胎瘤恶变占良性畸胎瘤的１．４％，其中鳞癌变７例（７／１１），腺癌变３例（３／１１），卵巢甲状腺肿恶变１例（１／１１）。５年平均生存率８０％，Ⅰ期为１００％，Ⅱ～Ⅲ期为０。结论：卵巢囊性畸胎瘤囊壁厚度大于１ｃｍ时，可疑恶变，应送冰冻病理检查；治疗以手术为主，加用化疗或放疗；早期患者预后明显好于中晚期；卵巢甲状腺肿恶变一般预后好
Objective: To investigate the treatment and prognosis of malignant ovarian cystic teratoma. Methods: Retrospective analysis was performed on 11 cases of malignancy of ovarian mature cystic teratoma in 20 years. Results: Ovarian mature cystic teratoma malignant transformation accounted for 1.4% of benign teratomas, including squamous cell carcinoma in 7 cases (7/11), adenocarcinoma in 3 cases (3/11), ovarian malignant transformation in 1 case (1 / 11). The 5-year average survival rate was 80%, I was 100%, and II-III was 0. Conclusion: When the cystic teratoma of the ovarian cyst has a cystic wall thickness greater than 1 cm, it is suspected of malignant transformation and should be sent for frozen pathological examination. The treatment is mainly based on surgery, plus chemotherapy or radiotherapy; the prognosis of early stage patients is obviously better than that of advanced stage; Ovarian goiter is malignant. Good prognosis
