<i>Objective:</i> To document the role of physicians' family history of cancer in terms of personal use of cancer preventive services and in recommending that patients receive such services. <i>Methods:</i> We examined the Women Physicians' Health Study, a questionnaire-based study of a representative sample of 4,501 female physicians in the United States. <i>Results:</i> Among the physicians surveyed, 38.9% (95% confidence interval 37.1–40.7) reported a family history of cancer. A physician's self-reported family history of a specific cancer was positively associated with the physician having had a more recent screening exam for that cancer. Family history of any cancer was positively associated with older age, white race, recent sigmoidoscopy, recent mammogram, digital rectal exam, a blood stool test, history of cigarette smoking and history of recent alcohol use. Physicians' family histories did not significantly influence the reported frequency of recommendations of screening services for their patients. <i>Conclusions:</i> The observed association between a positive physician family history and personal cancer prevention practices suggests that physicians are receptive to the concept of a positive family history of cancer as a risk factor for cancer. This could present an educational opportunity for physicians to emphasize the importance of cancer family history in patients, particularly with respect to underutilized services such as screening for colorectal cancer.

BACKGROUND: The objective of this study was to estimate the number of years after onset of a quadrivalent HPV vaccination program before notable reductions in genital warts and cervical intraepithelial neoplasia (CIN) will occur in teenagers and young adults in the United States. METHODS: We applied a previously published model of HPV vaccination in the United States and focused on the timing of reductions in genital warts among both sexes and reductions in CIN 2/3 among females. Using different coverage scenarios, the lowest being consistent with current 3-dose coverage in the United States, we estimated the number of years before reductions of 10%, 25%, and 50% would be observed after onset of an HPV vaccination program for ages 12–26 years. RESULTS: The model suggested female-only HPV vaccination in the intermediate coverage scenario will result in a 10% reduction in genital warts within 2–4 years for females aged 15–19 years and a 10% reduction in CIN 2/3 among females aged 20–29 years within 7–11 years. Coverage had a major impact on when reductions would be observed. For example, in the higher coverage scenario a 25% reduction in CIN2/3 would be observed with 8 years compared with 15 years in the lower coverage scenario. CONCLUSIONS: Our model provides estimates of the potential timing and magnitude of the impact of HPV vaccination on genital warts and CIN 2/3 at the population level in the United States. Notable, population-level impacts of HPV vaccination on genital warts and CIN 2/3 can occur within a few years after onset of vaccination, particularly among younger age groups. Our results are generally consistent with early reports of declines in genital warts among youth.

BACKGROUND: Overall, cervical cancer survival in the United States has been reported to be among the highest in the world, despite slight decreases over the last decade. Objective of the current study was to describe cervical cancer survival trends among US women and examine differences by race and stage. METHODS: This study used data from the CONCORD-2 study to compare survival among women (aged 15-99 years) diagnosed in 37 states covering 80% of the US population. Survival was adjusted for background mortality (net survival) with state- and race-specific life tables and was age-standardized with the International Cancer Survival Standard weights. Five-year survival was compared by race (all races, blacks, and whites). Two time periods, 2001-2003 and 2004-2009, were considered because of changes in how the staging variable was collected. RESULTS: From 2001 to 2009, 90,620 women were diagnosed with invasive cervical cancer. The proportion of cancers diagnosed at a regional or distant stage increased over time in most states. Overall, the 5-year survival was 63.5% in 2001-2003 and 62.8% in 2004-2009. The survival was lower for black women versus white women in both calendar periods and in most states; black women had a higher proportion of distant-stage cancers. CONCLUSIONS: The stability of the overall survival over time and the persistent differences in survival between white and black women in all US states suggest that there is a need for targeted interventions and improved access to screening, timely treatment, and follow-up care, especially among black women.
