PURPOSE: HPV self-sampling has previously been shown to increase cervical cancer screening among ethnic minority and immigrant women. We conducted a randomized pragmatic trial to examine the effectiveness of HPV self-sampling delivered via in-person versus by US mail for medically underserved Hispanic, Haitian, and non-Hispanic Black women living in South Florida. METHODS: We randomized women aged 30-65 who had not completed Pap smear screening in the past 3 years into two groups: (1) HPV self-sampling delivered in-person (IP) by a community health worker (CHW; IP + SS) or (2) HPV self-sampling delivered via US mail (SS + Mail)...

PURPOSE: Telomere length at birth sets the baseline for telomere shortening and may influence adult disease risk like cancer. Telomere length is heritable, but may also be a marker of exposures in utero, including those influencing racial differences in risk. We examined racial differences in telomere length in maternal and umbilical cord blood from male neonates, and maternal-neonate correlations to generate hypotheses. METHODS: Black and white pregnant women were recruited in 2006-2007 and followed to postpartum...

A greater understanding of the nature and drivers of poor breast cancer (BC) awareness in sub-Saharan Africa (SSA) will inform much needed awareness programmes. We aimed to assess the level and nature of BC awareness in the multi-country African Breast Cancer-Disparities in Outcome (ABC-DO) cohort of women newly diagnosed with BC during 2014-2017. Awareness indicators were assessed during a baseline interview at/near diagnosis. Logistic/ordinal regression was used to estimate odds ratios (OR) for indicators of BC awareness in relation to woman-level characteristics for individual settings and then meta-analyzed...

PURPOSE: Androgen deprivation therapy (ADT), used increasingly in the treatment of localized prostate cancer, is associated with substantial long-term adverse consequences, including incident diabetes. While previous studies have suggested that ADT negatively influences glycemic control in existing diabetes, its association with diabetes complications has not been investigated. In this study, we examined the association between ADT use and diabetes complications in prostate cancer patients...

PURPOSE: Recent studies have suggested height as a risk factor for glioma, but less is known regarding body mass index (BMI) or other anthropomorphic measures. We evaluated the association between body habitus and risk of glioma. METHODS: We evaluated the association of measures of height, BMI, waist circumference, and somatotypes with risk of glioma in two prospective cohorts, the Nurses' Health Study and the Health Professionals Follow-Up Study. RESULTS: We documented 508 incident cases of glioma (321 glioblastoma [GBM])...

PURPOSE: The goals of this study were to identify geographic and racial/ethnic variation in breast cancer mortality, and evaluate whether observed geographic differences are explained by county-level characteristics. METHODS: We analyzed data on breast cancer deaths among women in 3,108 contiguous United States (US) counties from years 2000 through 2015. We applied novel geospatial methods and identified hot spot counties based on breast cancer mortality rates. We assessed differences in county-level characteristics between hot spot and other counties using Wilcoxon rank-sum test and Spearman correlation, and stratified all analysis by race/ethnicity...

PURPOSE: Pharmacoepidemiology studies suggest prognostic benefits of aspirin in prostate cancer. We hypothesized that aspirin induces transcriptional changes in tumors or normal prostate tissue. METHODS: We analyzed the prostatic transcriptome from men diagnosed with prostate cancer during follow-up of the Physicians' Health Study 1 (PHS, n = 149), initially a randomized controlled trial of aspirin. Aspirin target genes were identified through systematic literature review and a drug target database...

The purpose of this study was to determine the past-year prevalence estimates of cigarette smoking and eligibility for low-dose computed tomography (LDCT) lung cancer screening among older U.S. adults and examine potential variations in these estimates by sexual orientation. Data were from the 2012-2013 National Epidemiologic Survey on Alcohol and Related Conditions (NESARC-III) and included in-person interviews with a nationally representative sample of non-institutionalized adults aged 18 and older. Eligibility for LDCT was based on U...

PURPOSE: Type II diabetes mellitus (T2DM) has consistently been associated with an increased risk of breast cancer, but the association of gestational diabetes mellitus (GDM) with breast cancer is less clear. T2DM and GDM may influence breast cancer risk through mammographic breast density, a strong risk factor for breast cancer. We examined whether T2DM and GDM are associated with higher mammographic breast density in a largely racial/ethnic minority sample. METHODS: We collected digital mammograms, anthropometric measures, and interview data from 511 racially diverse women recruited during screening mammography appointments between 2012 and 2016 (mean age 51 years; 70% Hispanic)...

There have been few published studies on differences between Blacks and Whites in the estimated effects of alcohol and tobacco use on the incidence of head and neck cancer (HNC) in the United States. Previous studies have been limited by small numbers of Blacks. Using pooled data from 13 US case-control studies of oral, pharyngeal, and laryngeal cancers in the International Head and Neck Cancer Epidemiology Consortium, this study comprised a large number of Black HNC cases (n = 975). Logistic regression was used to estimate adjusted odds ratios (OR) and 95% confidence intervals (CI) for several tobacco and alcohol consumption characteristics...

INTRODUCTION: Non-Hispanic black (NHB) women with breast cancer have poorer survival than non-Hispanic white (NHW) women. Although NHB women are more often diagnosed at later stages, it is less established whether racial disparities exist among women diagnosed with late-stage breast cancer, particularly when care is provided in the community setting. METHODS: Treatment and survival were examined by race/ethnicity among women diagnosed in 2012 with stage IIIB-IV breast cancer using the National Cancer Institute's population-based Patterns of Care Study...

BACKGROUND: Smoking is a major risk factor for bladder cancer, but the relationship between smoking cessation after initial treatment and bladder cancer recurrence has been investigated less frequently and not prospectively yet. METHODS: 722 non-muscle-invasive bladder cancer (NMIBC) patients (pTa, pT1, and CIS) from the prospective Bladder Cancer Prognosis Programme (BCPP) cohort, selected in the UK between 2005 and 2011, provided complete data on smoking behavior before and up to 5 years after diagnosis...

PURPOSE: Excess dietary fat consumption is strongly associated with the risk of colorectal cancer, but less is known about its role in the earliest stages of carcinogenesis, particularly within the proximal colon. In the following case-control study, we evaluated the relationship between the intake of dietary fats and the frequency of early proximal neoplasia [aberrant crypt foci (ACF) or polyps], detectable by high-definition colonoscopy with contrast dye-spray. METHODS: Average-risk screening individuals underwent a high-definition colonoscopy procedure as part of larger ongoing clinical study of precancerous lesions in the proximal colon...

Greater attention to social factors, such as race/ethnicity, socioeconomic position, and others, are needed across the cancer continuum, including breast cancer, given differences in tumor biology and genetic variants have not completely explained the persistent Black/White breast cancer mortality disparity. In this commentary, we use examples in breast cancer risk assessment and survivorship to demonstrate how the failure to appropriately incorporate social factors into the design, recruitment, and analysis of research studies has resulted in missed opportunities to reduce persistent cancer disparities...

Overweight and obesity are increasing worldwide, but the extent in breast cancer patients is unknown. The two aims were to study secular trends in preoperative body mass index (BMI), waist circumference, and breast volume and their impacts on clinical outcome. BMI, waist circumference, and breast volume were measured preoperatively in 24-99-year-old primary breast cancer patients (n = 640) in Sweden 2002-2016. The measurements were analyzed alone and combined in relation to recurrence and overall survival (OS)...

PURPOSE: Carbohydrate intake increases postprandial insulin secretion and may affect breast density, a strong risk factor for breast cancer, early in life. We examined associations of adolescent and early adulthood intakes of total carbohydrates, glycemic index/load, fiber, and simple sugars with breast density among 182 young women. METHODS: Diet was assessed using three 24-h recalls at each of five Dietary Intervention Study in Children (DISC) clinic visits when participants were age 10-19 years and at the DISC06 Follow-Up Study clinic visit when participants were age 25-29 years...
