观察纯型无性细胞瘤２７例，结果表明其发病年龄愈轻，恶性程度愈高。手术切除肿瘤彻底，及作放疗和／或化疗者，治疗后Ⅰ～Ⅱ期５年生存１４例（１４／１６），其中１例已达１５年。Ⅱ期肿瘤：行姑息性手术治疗者，平均生存８．８月（７／７），行量大限度缩瘤术－经腹膜外子宫逆行性切除术者，平均生存２４．２月（４／４），二者有差异。Ｉａ期中，行单纯患侧肿瘤切除术３例，２例行全宫加双侧附件切除，５例全部生存５年，Ｉａ期的年轻患者，如对侧卵巢及盆腔腹膜活检组织的病理检查阴性，便于术后追踪观察者可行患侧卵巢切除。
Observed in 27 cases of pure type of non-malignant cells, the results show that the younger the age of onset, the higher the degree of malignancy. Surgical resection of the tumor thoroughly, and for radiotherapy and / or chemotherapy, stage Ⅰ ~ Ⅱ 5 years after treatment, 14 cases (14/16), of which 1 case has reached 15 years. Patients with stage II tumors underwent palliative surgery with a median survival of 8.8 months (7/7). The patients with large-volume stenosis - those with extrauterine uterine retrograde resections had an average survival of 24.2 months (4 / 4) There are differences between the two. In stage Ia, 3 cases were treated with simple tumor resection, 2 cases were treated with whole-body plus bilateral attachment resection and 5 cases all survived for 5 years. The young patients in stage Ia, such as contralateral ovary and pelvic peritoneal biopsy, had negative histopathology , For postoperative follow-up observers feasible ipsilateral ovarian resection.
