Background: Guidelines recommend screening for cervical cancer among women 30 years or older 3 years after a normal Papanicolaou test (hereinafter referred to as Pap test) result or a combined normal screening result (normal Pap/negative human papillomavirus [HPV] test results). We assessed reported recommendations by US primary care physicians (PCPs) on screening intervals that incorporate HPV cotesting compared with Pap testing alone.

Methods: From September 1, 2006, through May 31, 2007, we conducted a mailed survey of a representative sample of 1212 PCPs, of whom 950 performed Pap tests and recommended the HPV test for screening or management.

In the US, federal and state behavioral surveillance systems routinely monitor self-reported sexual behavior and Papanicolaou (Pap) test use to identify high-risk populations, trends, and disparities and to guide and evaluate interventions for cervical cancer prevention and control. Clinical uptake of human papillomavirus (HPV) vaccination and testing necessitates the expansion of behavioral surveillance systems. Cervical disease is the main focus of HPV-related behavioral surveillance because of greater cancer incidence and mortality relative to other susceptible organs, and the availability of effective technologies for prevention and control.

Background: Population-based estimates of biological family size can be useful for planning genetic studies, assessing how distributions of relatives affect disease associations with family history and estimating prevalence of potential family support.

Methods: Mean family size per person is estimated from a population-based telephone survey (n = 1,019).

Results: After multivariate adjustment for demographic variables, older and non-White respondents reported greater mean numbers of total, first- and second-degree relatives.

Background: Blood transfusions may influence the recipients' cancer risks both through transmission of biologic agents and by modulation of the immune system. However, cancer occurrence in transfusion recipients remains poorly characterized.

Methods: We used computerized files from Scandinavian blood banks to identify a cohort of 888,843 cancer-free recipients transfused after 1968.

Background: Transfusion safety rests heavily on the health of blood donors. Although they are perceived as being healthier than average, little is known about their long-term disease patterns and to which extent the blood banks' continuous efforts to optimize donor selection has resulted in improvements. Mortality and cancer incidence among blood donors in Sweden and Denmark was investigated.

Background: Polymorphisms in glutathione-S-transferase (GST), N-acetyltransferase (NAT) 1, and CYP1A1 genes have been suggested as susceptibility factors for esophageal and gastric adenocarcinomas, but have not been consistently linked to elevated risks. In a population-based case-control study, we examined risks in relation to polymorphisms of the following genes: GSTP1; GSTM1; GSTT1; NAT1; and CYP1A1.

Methods: Histologically confirmed incident cases, ages 30-79, were identified in three US locations.

Background: Although mechanisms for detection of short-term complications after blood transfusions are well developed, complications with delayed onset, notably transmission of chronic diseases such as cancer, have been difficult to assess. Our aim was to investigate the possible risk of cancer transmission from blood donors to recipients through blood transfusion.

Methods: We did a register-based retrospective cohort study of cancer incidence among patients who received blood from donors deemed to have a subclinical cancer at the time of donation.

To improve the measurement of usual dietary intake, the National Cancer Institute developed a cognitively based Diet History Questionnaire (DHQ), which has been validated against four 24-h dietary recalls (4 24-HR) for energy, macronutrients, and several vitamins and minerals. This analysis used data from The Eating at America's Table Study (EATS) to determine the validity of estimates for carotenoids and tocopherols from the DHQ. Over the course of a year, 163 participants provided 1 or 2 blood samples and completed the DHQ and 4 24-HR.

Background And Objectives: Even with appropriate donor deferrals and advanced screening tests, the risk of disease transmission through blood transfusion cannot be completely disregarded. Efficient monitoring of possible disease transmission between blood donors and recipients should be an important component of a comprehensive haemovigilance system.

Materials And Methods: We assembled the Scandinavian Donations and Transfusions (SCANDAT) database, with data on virtually all blood donors and recipients who have been registered at least once in any of the computerized local blood bank databases in Sweden and Denmark since the start of computerized registration in 1966.

Commercial marketing materials may serve as a source of information for physicians about genetic testing for inherited cancer susceptibility (GTICS) in addition to medical guidelines, continuing education, and journal articles. The primary purposes of this study were to: (1) determine the percentage of physicians who received advertisements for GTICS early in the diffusion of commercial GTICS (1999-2000); (2) assess associated characteristics; and (3) measure the perceived importance of commercial advertisements and promotions in physicians' decisions to recommend testing to patients. A nationally representative, stratified random sample of 1,251 physicians from the American Medical Association (AMA) Physician Masterfile completed a 15-20 min mixed mode questionnaire that assessed specialty, previous use of genetic tests, practice characteristics, age, and receipt of advertising materials (response rate = 71%).
