眼科领域的恶性肿瘤往往可早期发现,所以预后良好,长期生存的患者比较多。为此,在初发肿瘤治愈后,发生其他恶性肿瘤的机会就多些。常染色体显性遗传的视网膜神经母细胞瘤的存在,在多重癌的研究上占有重要地位。一、视网膜神经母细胞瘤视网膜神经母细胞瘤是由网膜发生的恶性肿瘤,几乎都发生在3岁以下的婴幼儿,成人患病的很少,在种族和性别上发病率无差异。在日本的调查,比例为在出生15,000人中有一名,双眼和单眼之比例是1∶2.6,家族性发病者占全部病例的4.4%。初诊的平均年龄是:双眼者6.7个月;单眼者24.4个月。此肿瘤对放射线治疗敏感性高,现在不论双眼性还是单眼性,如在早期,不做眼球摘除也有可能治愈。如果在肿瘤向眼球外浸润前,做眼球摘除术,愈后良好。日 Malignant tumors in the ophthalmology are often found early, so the prognosis is good, more long-term survival of patients. To this end, in the initial tumor cure, the chance of other malignancies more. The existence of autosomal dominant retinoblastoma, occupy an important position in the study of multiple cancers. Retinal neuroblastoma Retinal neuroblastoma is a malignant tumor caused by the omentum, almost all occurred in infants under 3 years of age, very few adults, no difference in the incidence of race and gender. In Japan, the ratio was 1 in 15,000 births. The ratio of binocular to monocular eyes was 1: 2.6. Familial onset accounted for 4.4% of all cases. The average age of newly diagnosed patients was 6.7 months in both eyes and 24.4 months in monsters. The tumor is highly sensitive to radiation therapy, and now regardless of binocular or monocular, such as in the early, do not do enucleation may also be cured. If the tumor before infiltration to the eye, do enucleation, the more the better. day
