Background Long-term safety of assisted reproductive techniques (ART) is of interest as use is increasing. Cancer risk is known to be affected by parity. This study examined risk of cancer after fertility treatment, stratified by women's parity. Methods Data was obtained on all women (n=1 353 724) born in Norway between 1960-1996. Drug exposure data (2004-2014) was obtained from the Norwegian Prescription Database [drugs used in ART and clomiphene citrate (CC)]. The Medical Birth Registry of Norway provided parity status...

BACKGROUND: Studies examining associations between circulating concentrations of C-peptide and total adiponectin, two biomarkers related to obesity and insulin secretion and sensitivity and pancreatic ductal adenocarcinoma (PDA) risk have shown inconsistent results and included limited numbers of smokers. METHODS: We examined associations of these biomarkers and high molecular weight (HMW) adiponectin with PDA, overall, and by smoking status. We conducted a pooled nested case-control analysis in 3 cohorts (Prostate, Lung, Colorectal, and Ovarian Cancer Trial, Alpha-Tocopherol, Beta-Carotene Cancer Prevention Study, and Cancer Prevention Study-II), with 758 cases (435 current smokers) and 1052 controls (531 smokers) matched by cohort, age, sex, race, blood draw date and follow-up time...

BACKGROUND: The utility of incorporating detailed family history into breast cancer risk prediction hinges on its independent contribution to breast cancer risk. We evaluated associations between detailed family history and breast cancer risk while accounting for breast density. METHODS: We followed 222,019 participants aged 35-74 in the Breast Cancer Surveillance Consortium, of whom 2,456 developed invasive breast cancer. We calculated standardized breast cancer risks within joint strata of breast density and simple (1st-degree female relative) or detailed (1st-degree, 2nd-degree, or 1st- and 2nd-degree female relative) breast cancer family history...

BACKGROUND: Although the number of cancer survivors has increased substantially over the past several decades, the composition of survivors treated with radiotherapy is not well defined. Radiotherapy carries unique long-term toxicity risks for cancer survivors. This study describes the current estimates and future projections of the epidemiology of five-year cancer survivors who receive radiation therapy. METHODS: We used cancer incidence and survival data from the Surveillance, Epidemiology, and End-Results (SEER) database linked to US Census data to estimate the number of five-year cancer survivors treated with radiation between 2000 and 2030...

BACKGROUND: High-risk human papillomavirus (HR-HPV) testing has become a preferred cervical cancer screening strategy in some countries due to its superior sensitivity over cytology-based methods for identifying cervical intraepithelial neoplasia of grade 2 or worse (CIN2+). Improved sensitivity has been accompanied by reductions in specificity and concerns regarding over-screening and over-treatment of women with transient or non-progressing HR-HPV infections. Triage of HR-HPV+ women to colposcopy is, thus, warranted for appropriate management and treatment...

BACKGROUND: Obesity has been associated with substantially higher risk of inflammatory breast cancer (IBC) than other breast cancer. Here, we assess whether comorbidities of obesity, namely diabetes, abnormal glucose, dyslipidemia, and hypertension, are differentially related to risk of inflammatory breast cancer and other breast cancers by tumor stage at diagnosis (localized/regional/distant/unstaged). METHODS: We used linked SEER-Medicare data, with female breast cancer cases aged 66+ years identified by SEER registries (years 1992-2011)...

BACKGROUND: Obesity has been more consistently associated with breast cancer than type 2 diabetes (T2D). This analysis examined the combination of the two factors in the Multiethnic Cohort (MEC). METHODS: Women aged 45-75 years entered the MEC in 1993-1996 by completing a questionnaire. T2D status was self-reported at baseline, two follow-up questionnaires, and confirmed by administrative data. Cancers were identified from tumor registries and deaths through vital records until 2010...

BACKGROUND: HPV-related oropharyngeal SCC represents a distinct subgroup of head and neck tumours. We analyse the expression of cytokeratin 7, a junctional biomarker with a SEQIKA fragment which stabilises HPV-16 E7 transcripts, in oropharyngeal SCCs. METHODS: Archived tumour specimens and epidemiological data were collected from patients with oropharyngeal SCC over ten years. Briefly, DNA was extracted from tissue blocks and HPV testing carried out using SPF10 HPV PCR and INNO-LiPA HPV Genotyping...

BACKGROUND: Waterpipe tobacco smoking (WTS) is increasing in popularity despite evidence of harm and potential for dependence. Intervention development has been hampered by a lack of longitudinal, nationally-representative data on usage patterns and factors independently associated with WTS initiation. Therefore, we aimed to characterize key transitions between WTS states in a nationally-representative group of young adults, with particular attention to factors independently associated with initiation...

BACKGROUND: Epidemiological evidence on the association between nut consumption and lung cancer risk is limited. METHODS: We investigated this relationship in the Environment And Genetics in Lung cancer Etiology (EAGLE) study, a population-based case-control study, and the National Institutes of Health (NIH) American Association of Retired Persons (AARP) Diet and Health Study, a prospective cohort. We identified 2098 lung cases for EAGLE and 18,533 incident cases in AARP...

BACKGROUND: Weight cycling, defined by an intentional weight loss and subsequent regain, commonly occurs in overweight and obese women and is associated with some negative health outcomes. We examined the role of various weight-change patterns during early to mid- adulthood and associated risk of highly prevalent, obesity-related cancers (breast, endometrial, colorectal) in postmenopausal women. METHODS: 80,943 postmenopausal women (age: 63.4±7.4 years) in the Women's Health Initiative Observational Study were categorized by self-reported weight change (weight stable; weight gain; lost weight; weight cycled [1-3, 4-6, 7-10, >10 times]) during early to mid- adulthood (18-50 years)...

BACKGROUND: Invasive cervical cancer (ICC) and its premalignant phase (cervical intraepithelial neoplasia; CIN1-3) are distinguished by gynecological and pathological examination, yet no current methodologies can predict precancerous lesions that are destined to progress to ICC. Thus, development of reliable assays to assess patient prognosis is much needed. METHODS: HPV DNA methylation is significantly altered in cervical disease. Using an HPV-enrichment approach and next-generation DNA sequencing, methylation status was characterized in a case-case comparison of CIN (n = 2 CIN1; n = 2 CIN2; n = 20 CIN3) and ICC (n = 37) samples...

BACKGROUND: Overexpression of vascular endothelial growth factor is implicated in the pathogenesis of both renal cell carcinoma (RCC) and age-related macular degeneration (AMD). We evaluated the association between age-related macular degeneration and RCC risk. METHODS: We conducted a matched case-control study within a population-representative database from the United Kingdom (UK). Study cases were defined as individuals with any diagnostic code of RCC. For every case, four eligible controls were matched on age, sex, practice site, calendar time and duration of follow-up...

BACKGROUND: After adjusting for age and body mass index (BMI), mammographic measures - dense area (DA), percent dense area (PDA) and non-dense area (NDA) - are associated with breast cancer risk. Our aim was to use longitudinal data to estimate the extent to which these risk-predicting measures track over time. METHODS: We collected 4,320 mammograms (age range, 24-83 years) from 970 women in the Melbourne Collaborative Cohort Study and the Australian Breast Cancer Family Registry...

BACKGROUND: Prostate cancer has a propensity to invade and grow along nerves, a phenomenon called perineural invasion (PNI). Recent studies suggest that presence of PNI in prostate cancer has been associated with cancer aggressiveness. METHODS: We investigated the association between PNI and lethal prostate cancer in untreated and treated prostate cancer cohorts: the Swedish Watchful Waiting Cohort of 615 men who underwent watchful waiting, and the U.S. Health Professionals Follow-Up Study of 849 men treated with radical prostatectomy...

BACKGROUND: Endometrial tumors arise from a hormonally-responsive tissue. Defining subtypes by hormone receptors might better inform etiology and prediction of patient outcomes. We evaluated the potential role of tumor estrogen receptor (ER) and progesterone receptor (PR) expression to define endometrial cancer subtypes. METHODS: We measured semi-continuous ER and PR protein expression in tissue specimens from 360 endometrial primary tumors from the Nurses' Health Study...

BACKGROUND: We examined the relationship between estimated radiation dose from CT scans and subsequent Hodgkin lymphoma in the UK pediatric CT scans cohort. METHODS: A retrospective, record linkage cohort included patients aged 0-21 years who underwent CT scans between 1980 and 2002 and were followed up for cancer or death until 2008. Poisson regression analysis was used to evaluate the relationship between estimated radiation dose (lagged by two years) and incident Hodgkin lymphoma diagnosed at least two years after the first CT scan...

Characterization of toxicity associated with cancer and its treatment is essential to quantify risk, inform optimization of therapeutic approaches for newly diagnosed patients, and guide health surveillance recommendations for long-term survivors. The National Cancer Institute's Common Terminology Criteria for Adverse Events (CTCAE) provides a common rubric for grading severity of adverse outcomes in cancer patients that is widely used in clinical trials. The CTCAE has also been used to assess late cancer treatment-related morbidity, but is not fully representative of the spectrum of events experienced by pediatric and aging adult survivors of childhood cancer...

BACKGROUND: There are long-standing black-white disparities in colorectal cancer (CRC) incidence and outcomes in the United States. Incidence and stage at diagnosis reflect the impact of national efforts directed at CRC prevention and control. We aimed to evaluate trends in black-white disparities in both indicators over four decades to inform the future direction of prevention and control efforts. METHODS: We used Surveillance, Epidemiology, & End Results (SEER) data to identify whites and blacks with histologically confirmed CRC from January 1, 1975 through December 31, 2012...
