Abstract
The excellent resources of the Danish Cancer Registry (DCR) have allowed Dr. Børch and associates to examine the incidence of neonatal cancer in Denmark between 1943 and 1985.1 When cases which could not be verified by histopathological diagnosis are excluded, the incidence is about 2.13/100,000 live births, which is comparable to reports from Britain and the United States of 1.7 and 3.65/100,000 live births, respectively. Not surprisingly, neuroblastoma and leukemias were the most common cancers diagnosed in the first 28 days of life. Neonatal cancer was more common in boys than girls, and solid tumors were more frequently seen than the leukemias, which occur more often in older children.
