对脉络膜黑色素瘤病人已作眼球摘除再作放疗以往是有争议的。为了估价放疗的效果,本文比较了两组214例病人不同治疗后的存活率,第一组仅仅是眼球摘除,第二组眼球摘除后照射眼眶。放疗用的是 X-射线,在额、颞区,大多病人用高能量15.5MeV 离子加速器。每日量为200—300rad(拉德),直至总剂量达到6000rad(拉德)。为了避免统计学误差,特此考虑下列五点:(1)年龄、性别的分布,(2)治疗开始时肿瘤的大小相似(3)组织学表现相似,(4)随访日期相同,(5)治疗—眼球摘除或眼球摘除合併眼眶放射。
It is controversial that choroidal melanoma patients have undergone enucleation and then radiotherapy. In order to evaluate the effect of radiotherapy, this article compares the survival rate of two groups of 214 patients after treatment, the first group is only enucleation, the second group after enucleation of the orbit. Radiotherapy is the use of X-rays, in frontal and temporal areas, most patients with high-energy 15.5 MeV ion accelerator. The daily dose is 200-300 rad until the total dose reaches 6,000 rad. In order to avoid statistical errors, the following five points are hereby considered: (1) age and sex distribution; (2) tumor sizes at the start of treatment are similar (3) histological findings are similar; (4) follow-up dates are the same; - enucleation or enucleation combined with orbital radiation.
