Mortality from melanoma in children is a poorly understood and controversial problem in dermatology. There is paucity of research into this important public health dilemma. The purpose of this study was to characterize pediatric melanoma mortality in the United States and to evaluate trends over time.
Deaths were derived from a database of more than 75 million records of the U.S. Center for National Health Statistics based on routine death certification. Information on age, race, gender, and geographic location was available for years 1968 through 2004.
During the 37-year period, there were 643 deaths attributed to melanoma in children under 20 years of age in the United States, an average of 18 per year. The overall age-adjusted mortality rate for melanoma in children was 2.25 deaths per year (per 10 million at-risk individuals). Mortality rates were strongly associated with age. In the oldest age group (age 15-19 years) the mortality rate was approximately an order of magnitude 8-18 times higher compared to younger age groups. Mortality among males was 25% higher than females. Mortality rates for white children were more than twice as high as black children. Overall mortality from melanoma in children declined steadily from 1968 to 2004. The highest mortality rates were observed in Idaho, Nevada, Arizona, and New Mexico.
Although mortality from melanoma among children in the United State is low, the magnitude of the public health burden from this preventable cause of death is substantial. In contrast to results of studies suggesting that the incidence of melanoma may be rising in children and adolescents, the data suggest that mortality in these groups may be falling. Additional study is warranted to further characterize and ultimately reduce mortality from childhood melanoma.
儿童黑色素瘤死亡率是皮肤科领域一个了解甚少且颇具争议的问题。针对这一重要的公共卫生难题,相关研究匮乏。本研究旨在描述美国儿童黑色素瘤死亡率特征,并评估其随时间的变化趋势。
死亡数据来自美国国家卫生统计中心超过7500万条记录的数据库,基于常规死亡证明。可获取1968年至2004年的年龄、种族、性别和地理位置信息。
在这37年期间,美国20岁以下儿童中有643例死亡归因于黑色素瘤,平均每年18例。儿童黑色素瘤的总体年龄调整死亡率为每年2.25例死亡(每1000万高危个体)。死亡率与年龄密切相关。在最大年龄组(15 - 19岁),死亡率比年轻年龄组高出约一个数量级,即8 - 18倍。男性死亡率比女性高25%。白人儿童的死亡率是黑人儿童的两倍多。1968年至2004年,儿童黑色素瘤的总体死亡率稳步下降。爱达荷州、内华达州、亚利桑那州和新墨西哥州的死亡率最高。
尽管美国儿童黑色素瘤死亡率较低,但这种可预防死因所带来的公共卫生负担相当大。与一些研究表明儿童和青少年黑色素瘤发病率可能上升的结果相反,数据显示这些群体的死亡率可能在下降。有必要进一步开展研究,以更全面地描述并最终降低儿童黑色素瘤的死亡率。
