More children are surviving cancer but most suffer after-effects from the disease or the treatments for years and may need specialist care, a British researcher said on Wednesday.

　
一位英国研究人员周三表示，许多儿童正遭受癌症的威胁，但是更多的儿童却受到因为癌症或者因为长达一年之久的癌症治疗后遗症的折磨,这些儿童需要得到特别的护理。

Five-year survival rates of children with all types of cancers have increased from 23 percent in the 1960s to 70 percent in the 1990s, according to a study by Professor Jill Mann of the University of Birmingham in England.

　
根据英国伯明翰大学的Jill Mann教授的一项研究显示，患有各种类癌症的儿童，五年内的存活率，已经从1960年的23％上升到了1990年的70％。

But most of the 5,016 children who had been diagnosed and treated between 1960 and 1999 suffered subsequent medical problems that ranged from hearing impairment and learning disabilities to additional cancers.

　
但是，从1960年到1999年，接近有5016名被确证并经过治疗的儿童，治愈癌症后，他们却受到了其他一些药物并发症的折磨。比如听力损伤，学知苦难和患上其他类型的癌症等。

A small proportion, an estimated four percent of the children, developed another cancer but most of the problems are related to the treatments they had received.

　
有一小部分，也就是接近4％的儿童，他们经过治疗后，又患上了另外的一种癌症。但是，大部分的人认为他们出现的问题，是属于癌症治疗的后遗症。

About a third of the children had suffered from leukemia, a quarter had brain tumors and the remainder had other types of solid tumors.

　
大约有三分之一的儿童会在治疗后患上白血病，四分之一的儿童患上脑瘤，而其他一些儿童则患上其他类型的肿瘤。

Only 18 percent had no chronic medical disorders afterwards.

　
只有18％的儿童在癌症治疗后，没有发生什么后遗症现象。

Children who had been treated for brain tumors had the most problems. The after-effects included hormone, neurological and psychological problems.

　
脑瘤儿童患者经过治疗后，最容易出现后遗症。这些后遗症主要包括，荷尔蒙，神经和心理等方面的问题。

Former leukemia patients who had received radiotherapy suffered from under-activity of the pituitary gland, metabolic disorders or learning disabilities. Chemotherapy drugs were associated with cardiac problems.
治疗早期白血病患者的方法，主要是通过放射性疗法治疗，从而降低脑下垂体的活动型性；改良新陈代谢混乱或者学知障碍的问题。但是，化学性药物一般会引发心脏问题。
