松果体区生殖细胞肿瘤放射外科治疗的合理性探讨

目的 探讨立体定向放射外科作为一线方案治疗松果体区生殖细胞肿瘤的合理性.方法 回顾性分析14例经伽玛刀或X-刀治疗的松果体区生殖细胞肿瘤患者的临床资料,重点研究肿瘤放射外科治疗后变化及复发、转移情况.结果 14例患者于放射外科治疗后11 d至106个月再次入院.肿瘤放射外科治疗后缓慢增大1例,无明显变化2例,缩小后再增大1例,基本消失后原位复发2例,消失后周边复发4例,原位复发并种植转移2例,原位消失但出现种植转移2例.病理为:生殖细胞瘤5例、混合型生殖细胞肿瘤4例、成熟畸胎瘤3例、非成熟畸胎瘤和卵黄囊瘤各1例.结论 放射外科不能作为松果体区生殖细胞肿瘤的单一治疗方法.假使已采用放射外科治疗,则应依据肿瘤标记物结果和治疗后肿瘤的变化情况,及时手术或综合治疗.

Abstract：

Objective To discuss the rationality of the stereotaxic radiosurgery as the first therapy strategy on pineal region germ cell tumors.Methods To retrospectively analyze the clinical materials of 14cases which received the treatment of gamma knife or X- knife.The condition of tumor changing,recurring and metastasize post- radiosurgery were emphasized.Methods All the patients of 14 cases were admitted again from 11 days to 106 months after which had received radiosurgery.The tumor increasing slowing with 1cases,no marked change with 2 cases,repeated increasing after diminution with 1 case,situ recur after essential disappear with 2 cases,ambitus recur after disappear with 4 cases,situ recur and implantation metastasis 2 cases,situ disappear but implantation metastasis with 2 cases.The pathology results were 5germinomas,4 mixed germ cell tumors,3 mature teratomas,1 unmature teratoma and 1 yolo sac tumor.Conclusion Radiosurgery cant be regarded as the exclusive treatment for pineal region germ cell tumors.If the patients received the radiosurgery,they should be operated or combined therapy in time according the results of tumor marker and the condition of tumor changing.
