近10—15年来,白血病的发病率有了增加的趋势,这一点可由国内和国外学者的著作证实。斯徒尔德瑞斯氏(1951年)报告,在美国,小儿白血病不是一种罕见的疾病,因为早在1942年白血病的死亡率就比猩红热、白喉、天花、伤寒、流行性脊髓灰质炎、疟疾、流行性脑脊髓膜炎的死亡率总和还要高。虽然化验技术的日臻完善和病人均有广泛住院治疗的可能性,会促使我们发现白血病,可是因此就把白血病发病率的增长都归之于诊断技术的改进这一点上,还颇值得怀疑。根据许多学者的一致意见,诊断小儿白血病是有很大困难的。急性白血病的患儿在病情还没有最后发展到最严重的地步而住院治疗之前,常被当作其他疾 The incidence of leukemia has tended to increase over the past 10-15 years, as evidenced by the work of domestic and foreign scholars. Childrens leukemia is not a rare disease in the United States, as reported by Stuart Reese (1951), since leukemia mortality was earlier than that of scarlet fever, diphtheria, smallpox, typhoid, epidemic polio, In malaria, the combined death rate of meningococcal meningitis is even higher. Although advances in laboratory techniques and the possibility of widespread hospitalization by patients have led us to discover leukemia, it is questionable whether the increase in the incidence of leukemia should be attributed to the improvement of diagnostic techniques. According to the consensus of many scholars, it is very difficult to diagnose childhood leukemia. Children with acute leukemia are often treated as other illnesses until their condition has finally progressed to the point where they are hospitalized
