Childhood leukemia in Norway from 1963-1974 with special emphasis on own material.

Childhood leukemia in Norway in the period 1963-1974 with special emphasis on own material. Acta Paediatr Scand, 65:529, 1976. -A nation wide up-to-date survey of childhood leukemia in Norway including 499 cases in the period 1963-1974 is presented. The median survival for all cases was about one year. Around 20% of the 499 cases were still alive in Novemeber 1974. Twenty-five of the children were off therapy without any signs of relapse. In our own material thirteen of 42 cases of acute lymphatic leukemia (ALL) were still in primary remission after 3-9 1/2 years. Twelve of them were still off therapy and none had relapsed. Best results were achieved in the 31 cases of ALL followed closely by us all the time. The number of cases in continuous complete remission and the median survival rate in this series compares favourably with the last two studies published by the St. Jude group.
