Yapilan bazi arastirmalar, koroidea malign melanumunda tedavi olarak entikleasyon uygulanmasindan sonraki ilk birkac yil i¢gerisinde uzak metastaz oraninin arttigini géstermis, ve bu durum, operasyon sirasindaki travmaya bagh mikrometastazlar ve operasyon nedeniyle hasta direncinde azalma, ile aciklanmistir. Yaptigimuz galigsmada postoperatif malign hücre yayilimini azaltmak dustncesinden yola cikarak uveal malign melanoma sahip 40 hastaya preoperatif olarak ginde 400cGy’den total 2000 cGy eksternal orbital isinlama yaptuk. Bu hastalarn retrospektif olarak incelenen, sadece enukleasyon yapilmis 75 hastalik kontrol grubu ile karsulastirdifimizda, tedavi grubunda 5 yilin tizerindeki yasamda gértilen metastaz orani istatistiksel olarak anlamh dlctide daha az (Tedavi grubunda % 5.8, kontrol grubunda % 33.3 ve p< 0.01) ve tahmini yasam streleri de daha yuksek olarak bulundu, ilk 3 yilda gérilen metastaz oram daha az bulunmasina ragmen (Tedavi grubunda % 10, kontrol grubunda % 14.6) istatistiksel olarak anlamli degildi (p> 0.05).

Certain researches have shown an increase in metastatic disease during the first two or three years after enucleation as a treatment of choroidal malign melanomas, and explained that this peak was a result of micrometastasis at the time of the surgical maniplations and the change in the immune status of the patient because of the operation. In this study, 2000 cGy external radiation was given preoperatively, on the area of orbita, in 400 cGy daily fractions to 40 patients who had choroidal malign melanomas for the purpose of reducing the dissemination of malign cells after enucleation. When we compare this treatment group with the retrospective control group of 75 patients who had only enucleation as a treatment, in the first group
distant metastases over five years after treatment were significantly reduced (In the treatment group % 5.8, in the control group % 33.3 and p< 0.01) and survival were longer. Distant metastases during the first three years were less (in the treatment group % 10, in the control group % 14.6), but not significant (p> 0.05).
