卵巢未成熟畸胎瘤是卵巢恶性肿瘤年轻病人中较常见的一种肿瘤其恶性程度较高,很早即发生转移,手术切除肿瘤后,常于短期内复发,死亡率也较高。多年来我们对该肿瘤进行长期追踪,并将其病理形态特点与临床疾病过程密切结合,进行了细致研究。1949-1983年共收治纯型卵巢未成熟畸胎瘤29例。1968年以前,对该肿瘤的治疗原则上不论是原发或转移病灶均予以手术切除,但若在肝或横隔部有转移灶则放弃手术;肿瘤复发一般也进行手术治疗,但若再次复发,则很少考虑第三次手术。1969年以后,手术治疗方案更为积极 Ovarian immature teratoma is a more common type of tumor in young patients with ovarian cancer. It has a high degree of malignancy and metastasize very early. After surgical resection of the tumor, it often recurs in the short term and the mortality rate is also high. Over the years, we have conducted long-term follow-up of the tumor and closely combined its pathological features with clinical disease processes and conducted detailed studies. From 1949 to 1983, 29 cases of pure ovarian immature teratomas were admitted. Prior to 1968, the treatment of the tumor was surgically resected in principle whether the primary or metastatic lesions, but if there is a metastasis in the liver or transverse septum to give up surgery; tumor recurrence is generally also treated surgically, but if recurrence , the third surgery is rarely considered. After 1969, the surgical treatment program was more positive
