- Abstract
Traditionally, controls in US pediatric cancer studies were selected through random digit dialing. With declining participation and lack of nonparticipant information, random digit dialing (RDD) controls may be substandard. Birth certificate (BC) controls are an alternative, because they are population based and include data from nonparticipants. The authors examined controls collected by random digit dialing and birth certificates for a Children's Oncology Group case-control study of infant leukemia in 1995-2006. Demographic variables were used to assess differences in RDD and BC controls and their representativeness. RDD and BC controls did not differ significantly with regard to maternal variables (age, race, education, marital status, alcohol during pregnancy) or child variables (sex, gestational age, birth weight), but they varied in smoking during pregnancy (22% RDD controls, 12% BC controls) (P = 0.05). The study's combined control group differed significantly from US births: Mothers of controls were more likely to be older (29.8 vs. 27.2 years), white (84% vs. 59%), and married (85% vs. 67%) and to have >16 years of education (37% vs. 25%). Control children were more often full term (88% vs. 81%) and heavier (3,436 vs. 3,317 g). Finally, participating BC mothers were likely to be older and to have more education than nonparticipants. Thus, the study's control groups were comparable but differed from the population of interest.

- Abstract
Purpose: A significant increase in the incidence of neuroblastoma occurred among a 5-year birth cohort (May 1989 to April 1994) during an active urinary screening program for its early detection. We examined the postscreening incidence of neuroblastoma in the subsequent 5-year birth cohort (May 1994 to April 1999), with follow-up to 2002, to determine whether the incidence remained increased., Patients and Methods: We reviewed institutional records of patients diagnosed with neuroblastoma during the period from 1994 to 2002 who were born in 1994 to 1999 in the province of Quebec, as well as in the state of Minnesota and the province of Ontario, regions that had served as controls during the screening interval. We calculated and compared incidence rates during the 1994 to 2002 time period., Results: For the 5-year birth cohort as a whole, the rate of newly diagnosed neuroblastoma was higher in Quebec than in the control populations of Minnesota and Ontario (standardized incidence ratio, 1.34; 95% CI, 1.03 to 1.70). However, in years 4 and 5 of the interval, population-based incidence declined to the same levels as those seen in the control areas., Conclusion: The institution of a urinary screening program for neuroblastoma led to increased awareness of the diagnosis and an elevated rate of diagnosis even after the completion of the screening evaluation. However, this halo effect was transient, with diagnostic rates subsequently decreasing within the range seen in control populations.

- Abstract
Background: The Hmong, an isolated, agrarian people from southern China, migrated to the mountainous regions of what are today Vietnam, Cambodia, and Laos. Minnesota has the second largest Hmong population in the United States. The authors compared frequencies of common genetic polymorphisms believed to influence risk of malignancy to determine whether frequencies in the Hmong are different from those in other Asian populations and in white Minnesotans., Methods: Genotyping for glutathione S-transferase micro1 (GSTM1), glutathione S-transferase theta1 (GSTT1), myeloperoxidase (MPO) (C(-)463T), nicotinamide adenine dinucleotide phosphate:quinone oxidoreductase (NQO1) (C609T), 5,10-methylenetetrahydrofolate reductase (MTHFR) (C677T), MTHFR (A1298C), methionine synthase reductase (MTRR) (A66G), X-ray repair cross complementing 1 (XRCC1) 194 (Arg194Trp), XRCC1 280 (Arg280His), and XRCC1 399 (Arg399Gln) alleles was performed by TaqMan analysis using DNA isolated from newborn heel-stick spots provided by the Minnesota Department of Health., Results: The Hmong had significantly higher frequencies of the NQO1 T allele and the XRCC1 Trp polymorphism (Arg194Trp) and had significantly lower frequencies of the G allele in MTRR (A66G) and the T allele in MTHFR (C677T) compared with white Minnesotans. The Hmong also were significantly more likely to lack the GSTM1 and GSTT1 genes compared with whites (82% vs. 54% and 61% vs. 18%, respectively). Genotype frequencies were similar for MTHFR (A1298C), MPO (C(-)463T), and XRCC1 (Arg280His, Arg399Gln). Genotype frequencies at these loci also were compared with those reported for other Asian populations and showed notable differences between the Hmong and Chinese/Taiwanese, Korean, and Japanese populations., Conclusions: The genetic differences identified have implications for both cancer etiology and prognosis in this unique population., (Copyright 2003 American Cancer Society.)

- Abstract
In this article we report on the effectiveness of a community-based, culture-specific, controlled trial of intensive peer education aimed at preventing lead burden in children 0-36 months of age within a neighborhood with high risk for lead exposure. Mothers (n = 594) were randomly assigned to control or intervention groups. Offspring blood lead levels were assessed every 4 months. All participants received brochures on basic lead prevention strategies. Intervention participants were offered 20 bi-weekly educational sessions by same-ethnicity peer educators over the course of 1 year, and quarterly booster sessions for 2 years afterward. The intervention group's educational curriculum included information on lead sources (e.g., paint, dust, water, soil, and risks from home repairs and remodeling), health consequences of lead burden, and strategies to reduce lead exposure, including household cleaning, hygiene, safe use of water, and nutritional recommendations. Results indicated that of the 378 children contributing sufficient blood data for analysis, 23% had blood lead levels > 10 micro g/dL before 3 years of age. Intervention participants were more likely to maintain blood lead levels < 10 micro g/dL than were controls (81% vs. 73%; p = 0.08). Multivariate analyses demonstrated that the intervention reduced the risk of blood lead levels > 10 micro g/dL by approximately 34%. We conclude that although intensive education resulted in a lower proportion of children with elevated lead levels, education alone cannot be relied upon to prevent lead burden.

- Abstract
Background: The Hmong are an isolated, agrarian people who settled in the mountainous regions of what today are Vietnam, Cambodia, and Laos. After the Vietnam War, many Hmong were relocated to the U.S. Minnesota has the second largest population (after California) of Hmong individuals. The objective of this study was to examine cancer incidence in this population, because it may indicate areas for targeted surveillance and intervention., Methods: The Minnesota Cancer Surveillance System database was screened for Hmong surnames, and proportional incidence ratios (PIRs) were calculated for the period 1988-1999., Results: Compared with all Minnesotans, the Hmong population had increased PIRs for nasopharyngeal cancer (PIR, 39.39; 95% confidence interval [95% CI], 21.01-66.86), gastric cancer (PIR, 8.70; 95% CI, 5.39-13.25), hepatic cancer (PIR, 8.08; 95% CI, 3.88-14.71), and cervical cancer (PIR, 3.72; 95% CI, 2.04-6.20) and had decreased PIRs for prostate cancer, breast cancer, Hodgkin disease, and melanoma., Conclusions: The current observations have implications for cancer control interventions. In particular, an increased incidence of cervical cancer might be addressed in part by targeting culturally sensitive screening programs in the Hmong population., (Copyright 2003 American Cancer Society.)

- Abstract
Background: With increasing numbers of childhood cancer survivors, direct sequelae of cancer therapy and psychosocial outcomes are becoming more important. The authors described psychosocial outcomes (education, employment, health insurance, and marriage) for survivors of pediatric lower extremity bone tumors., Methods: The long-term follow-up study of the Childhood Cancer Survivor Study is a multiinstitutional cohort study comprising 14,054 individuals who have survived for 5 or more years after treatment for cancer diagnosed during childhood or adolescence. Baseline demographic and medical information were obtained. Six hundred ninety-four survivors had osteosarcoma or Ewing sarcoma of the lower extremity or pelvis and were classified by amputation status and by age at diagnosis. The median age at diagnosis was 14 years old with a median of 16 years of follow up since diagnosis. Demographic characteristics were used to analyze the rates of psychosocial outcomes., Results: Amputation status and age at diagnosis did not significantly influence any of the measured psychosocial outcomes. Education was a significant positive predictor of employment, having health insurance, and being currently in their first marriage. Male gender predicted ever being employed and female gender predicted having health insurance and marriage. When compared with siblings, amputees had significant deficits in education, employment, and health insurance., Conclusions: Overall, no differences between amputees and nonamputees were found. However, gender and education play a prominent role. When compared with siblings, amputees in this cohort may benefit from additional supports., (Copyright 2003 American Cancer Society.DOI 10.1002/cncr.11363)
