Cancer in Nevadas Adolescent and Young Adult PopulationNevada Cancer Institute, Las Vegas, NV To the Editor: We read with interest the articles by Albritton et al1 and Howell et al.2 Because we are the cancer institute of Nevada,3 a neighboring state to Utah, but are demographically dissimilar (Hispanics comprise 25% of the Nevada population but only 8% of the Utah population), we decided to conduct an analysis on 5 years (1999 to 2003) of cancer data focusing on Nevada residents younger than 24 years. Such an analysis will potentially assist the Nevada Cancer Institute (NVCI) in developing research and programmatic strategies to address healthcare provider shortages. It will also aid in the development of treatment options in Nevada for cancers found in children, adolescents, and young adults, such as the Fallon leukemia cluster.4 Five years of population-based cancer registry data5 were reviewed for the population aged 0 to 24 years. In Nevada, 675 cases of cancer were diagnosed in residents younger than 24 years. Children aged 0 to 4 years comprised approximately 21% of the cancer cases, children aged 5 to 14 years comprised approximately 24%, and the adolescent and young adult (AYA) population (15 to 24 years) comprised approximately 55%. In the AYA population, 66% were white, 20% were hispanic, 5% were black, and 8% were others/unknowns. Both referenced articles1,2 focused on ages 15 to 19. In Nevada, there were 369 patients in this AYA subpopulation: thyroid (15%), Hodgkins lymphoma (10%), skin (9.8%), brain/CNS (7%), leukemia (7%), and non-Hodgkins lymphoma (6.7%). The majority of the cases (66%) were residents of Clark County (Las Vegas area) or Washoe County (21%; Reno area). The mortality rate for this AYA population was 3.6 per 100,000. Because of the limitations of the Nevada Interactive Health Database,5 we were unable to analyze treatment or survival data. However, NVCI has recently developed a Population Science & Cancer Control Division and is in the process of entering into a data-sharing agreement with the State of Nevada Health Division to obtain Cancer Registry data. Having these data will allow NVCI to delineate Nevadas populations and build collaborations to ensure all treatment options, such as clinical trials for AYA populations, are available in Nevada.
