Pediatric cancer in Kentucky: good news.

: Pediatric cancer is one of the more poignant aspects associated with the occurrence of this prominent chronic disease. Nationally, pediatric cancers occur with vastly lesser frequency than does adult disease, about 1:40 ratio. Nationally the rate is 14.6 per 100,000 population, age, 0-14 years. In Kentucky, all pediatric cancer rates are consistently lower, a statewide rate of 11.3 per 100,000. A rigorous examination was made for any evidence of unusual risk for pediatric cancer within the state; none was found. The population center of Jefferson County was examined with a bit greater detail, owing simply to the larger number. Again, no basis for public health or follow-back was identified. Among the most frequent pediatric cancers, leukemia, central nervous system, and brain were studied for implications of residential proximity to environmental hazards; no evidence of increased risk was identified. In all of the state, only Hardin County evinced any excess pediatric cancer risk, i.e., was significantly greater than the national rates. Yet this highly mobile population [owing to a large military population] may simply represent rates that are more compatible with those of the nation. For the Kentucky comprehensive disease control efforts, then, no emphasis need be placed with pediatric cancer beyond the intense personal tragedy that it poses.
