In 1971-1988, 4,021 malignant tumors occurring among children under 15 years of age were registered in the Osaka Cancer Registry, a population-based registry which covers Osaka Prefecture, Japan. These patients were reclassified into 12 diagnostic groups by Birch's scheme using information on clinical diagnosis, histology and primary site. The annual age-standardized incidence rate for childhood cancer per million children was 130.3 for males and 104.9 for females in 1971-88. Comparing the incidence rates for both sexes in 1981-88 with those in 1971-80 in Osaka, we observed a significant decrease of acute non-lymphocytic leukemia (ANLL) and a significant increase of all cancers, acute lymphocytic leukemia, non-Hodgkin lymphoma, sympathetic nervous system tumors, soft-tissue sarcomas, and gonadal and germ-cell tumors. Age-standardized incidence rates in around 1971-80 of the above-mentioned diagnostic groups were compared among 4 population-based registries; Osaka, Miyagi (Japan), SEER (U.S.), and the National Registry of Childhood Tumors (England and Wales). Rates for ANLL and gonadal and germ-cell tumors were higher and those for other diagnostic groups were lower in Osaka, especially for Hodgkin's disease. Thus, in 1980-88 in Osaka, rates for Hodgkin's disease remained low and rates for gonadal and germ-cell tumors increased, though rates for other cancers appeared to resemble the levels in caucasian populations. The incidence of childhood cancer in Japan was estimated according to the diagnostic groups in Birch's scheme.

As little is known about the aetiology of cancer in children, analysis of time trends may be useful. Recent data on time trends for paediatric cancers are very limited. We report here on trends in the incidence of 15 categories of cancer in children under 15 years of age from 1970 to 1989, using data from the Greater Delaware Valley Pediatric Tumor Registry in the US. Total cancer incidence increased 1% per year (P < 0.001). Neither acute lymphocytic leukaemia, acute myelocytic leukaemia, nor total leukaemia incidence changed significantly. In contrast, the incidence of central nervous system (CNS) tumours rose 2.7% per year (P < 0.001). All three subgroups of this category, glioma, primitive neuroectodermal tumor (PNET)/medulloblastoma, and other CNS tumours, showed increases. For glioma and PNET/medulloblastoma, trends differed by age, race, and/or gender. Among the other childhood cancers, significant increases were observed for non-Hodgkin lymphoma and neuroblastoma. For osteosarcoma and retinoblastoma, no overall change in incidence was observed, although decreases were observed in some age and race subgroups. The rise in CNS tumour incidence confirms previous reports from the US and Great Britain. The lack of change for acute lymphocytic leukaemia conflicts with other data from the US, but diagnostic changes appear to explain at least part of the discrepancy. The increase in neuroblastoma has also been observed in Great Britain. In contrast to our finding, investigators in the US and Great Britain have reported no rise in non-Hodgkin lymphoma. Analyses for more of the childhood cancers from other registries would aid in detecting and interpreting incidence trends in recent years.
