一项新近研究显示:在欧洲,儿童癌症的总发病率正以平均每年1.1%的速度上升。研究人员发现,自1978年到1997年,儿童癌症的年龄标准化发病率已从每百万名儿童120人上升至141人(《欧洲癌症杂芯》2006;42:1961-1)。尽管发病率的这一升高部分原因是由于患者的诊断及登记状况发生改变所致,但作者认为,该发病率增加的程度以及其他的因素均指向另有其他 A recent study shows that in Europe, the overall incidence of childhood cancer is rising at an average rate of 1.1% per year. Researchers found that the age-standardized incidence of childhood cancer rose from 120 to 141 people per million children from 1978 to 1997 (Eurochaar 2006; 42: 1961-1). Although this increase in morbidity is due in part to changes in patient diagnosis and registration status, the authors believe that the extent of this increase in incidence and other factors point to something else
