卵巢畸胎瘤恶变不多见,恶变率为1～3%,本文为6.8%。卵巢畸胎瘤分为成熟型与未成熟型。本文14例均为成熟型曩性畸胎瘤恶变。其中最多见的是鳞状上皮癌(11/14),第二位是粘液腺癌(2/14),第三位为纤维肉瘤变(1/14)。疗效总的一年生存率为57.1%(8/14),三年存活率为50.0%(6/12),五年生存率为50.0%(6/12),10年生存率为33.3%(2/6)。临床期别愈早疗效愈高,病理类型中鳞状上皮癌,粘液性腺癌,早期疗效最佳,晚期及纤维肉瘤疗效最差。
Ovarian teratoma malignant transformation is rare, malignant transformation rate of 1-3%, this article was 6.8%. Ovarian teratomas are divided into mature and immature types. In this article, 14 cases were all malignant transformation of mature teratoma. The most common is squamous cell carcinoma (11/14), the second is mucinous adenocarcinoma (2/14), and the third is fibrosarcoma (1/14). The overall one-year survival rate was 57.1% (8/14), the three-year survival rate was 50.0% (6/12), the five-year survival rate was 50.0% (6/12), and the 10-year survival rate was 33.3% ( 2/6). The earlier the clinical stage, the higher the curative effect. The pathological type of squamous cell carcinoma and mucinous adenocarcinoma have the best early effects. The late stage and fibrosarcoma have the worst effect.
