The potential etiologic role of household pesticide exposures was examined in the Northern California Childhood Leukemia Study. A total of 162 patients (0-14 years old) with newly diagnosed leukemia were rapidly ascertained during 1995-1999, and 162 matched control subjects were randomly selected from the birth registry. The use of professional pest control(More)
OBJECTIVES No previous study has concurrently assessed the associations between meat intake, meat-cooking methods and doneness levels, meat mutagens (heterocyclic amines (HCAs) and polycyclic aromatic hydrocarbons), heme iron, and nitrite from meat and colorectal adenoma in asymptomatic women undergoing colonoscopy. METHODS Of the 807 eligible women in a(More)
Imazethapyr, a heterocyclic aromatic amine, is a widely used crop herbicide first registered for use in the United States in 1989. We evaluated cancer incidence among imazethapyr-exposed pesticide applicators enrolled in the Agricultural Health Study (AHS). The AHS is a prospective cohort of 57,311 licensed pesticide applicators in the U.S., enrolled from(More)
Objective: The authors evaluated the relation between maternal pregnancy loss, birth characteristics, and childhood leukemia in the Northern California Childhood Leukemia Study. Methods: Incident cases of childhood leukemia (age 0–14 years) were rapidly ascertained, and controls were randomly selected from birth records and individually matched to cases. A(More)
Polycythemia vera (PV) and essential thrombocythemia (ET) are common types of myeloproliferative disorders (MPD), the prevalence of which has not been well documented in the United States. Recent breakthroughs in the molecular etiology of these disorders and the accelerated development of targeted pharmacotherapeutics to treat them underscore the need to(More)
Meats cooked at high temperatures, such as pan-frying or grilling, are a source of carcinogenic heterocyclic amines and polycyclic aromatic hydrocarbons. We prospectively examined the association between meat types, meat cooking methods, meat doneness, and meat mutagens and the risk for prostate cancer in the Agricultural Health Study. We estimated relative(More)
The relation between diet, lifestyle, and acute myeloid leukemia was assessed in a US cohort of 491,163 persons from the NIH-AARP Diet and Health Study (1995-2003). A total of 338 incident cases of acute myeloid leukemia were ascertained. Multivariate Cox models were utilized to estimate hazard ratios and 95% confidence intervals. Compared with those for(More)
We evaluated cancer risk from DDVP (2,2-Dichloroethenyl dimethylphosphate) exposure among pesticide applicators enrolled in the Agricultural Health Study (AHS) cohort. The AHS is a cohort of 57,311 pesticide applicators in North Carolina and Iowa, enrolled from 1993 to 1997 and followed for cancer through 2004. A comprehensive questionnaire collected(More)
BACKGROUND Myelodysplastic syndromes (MDS) became reportable to the Surveillance, Epidemiology, and End Results (SEER) Program (the United States cancer surveillance program) in 2001. This provided the first opportunity to examine the incidence and survival of patients with MDS in the United States using a large, population-based database. METHODS The(More)
Myelodysplastic syndromes (MDS) comprise a heterogeneous group of clonal hematopoietic stem cell malignancies with significant morbidity and high mortality. The incidence of MDS increases markedly with age, and the disease is most prevalent in individuals who are white and male. It is conservatively estimated that >10,000 new cases of MDS occur in the(More)
