Androgens have been suspected to be involved in the initiation of renal cell carcinoma because of a two-fold increased risk in men compared with women. To investigate the role of self-reported finasteride or oral contraceptive use in the Prostate, Lung, Colorectal, and Ovarian (PCLO) to determine whether the androgen receptor reduces renal cancer development. We query the PCLO trial for predictor variables from the baseline questionnaire and follow-up questionnaires enquiring medication use, specifically the use of 5-α reductase inhibitors (dutasteride or finasteride) and oral contraceptive therapy...

Low-dose computed tomography (LDCT) screening trials have based their risk selection algorithm on age and tobacco exposure, but never on pulmonary risk-related biomarkers. In the present study, the baseline inflammatory status, measured by C-reactive protein (CRP) level, and lung function, measured by forced expiratory volume in 1 s (FEV1), were tested as independent predictors of all-cause mortality in LDCT-screening participants. Between 2000 and 2010, 4413 volunteers were enrolled in two LDCT-screening trials, with evaluable baseline CRP and FEV1 values: 2037 were included in the discovery set and 2376 were included in the validation set...

The distinction between benign and malignant papilloma of the breast through percutaneous needle biopsy can be difficult because of limited samples; the underestimation rate can be up to 25%. The aim of this study is to identify clinical and histological factors associated with underestimation, invasive ductal carcinoma, or ductal in-situ carcinoma (DCIS) of the breast found in surgical specimens from papillary lesions. This may contribute toward selection of patients for a follow-up strategy without the need for surgical excision...

We reviewed available evidence on coffee drinking and the risk of all cancers and selected cancers updated to May 2016. Coffee consumption is not associated with overall cancer risk. A meta-analysis reported a pooled relative risk (RR) for an increment of 1 cup of coffee/day of 1.00 [95% confidence interval (CI): 0.99-1.01] for all cancers. Coffee drinking is associated with a reduced risk of liver cancer. A meta-analysis of cohort studies found an RR for an increment of consumption of 1 cup/day of 0.85 (95% CI: 0...

Hereditary breast and ovarian cancer is an inherited syndrome associated with BRCA1/2 germline defects. The identified mutations are classified as missense, large deletion, insertion, nonsense and splice-site variants with a deleterious impact on BRCA1/2 function. Part of these forms the well-documented truncating mutations, and missense variants represent a clinical dilemma as the pathogenic role is yet to be clearly shown. In this systematic review, we collected these missense variations with a documented deleterious function...

Cutaneous malignant melanoma, whose incidence is increasing steadily worldwide, is the result of complex interactions between individual genetic factors and environmental risk factors. Ultraviolet radiation represents the most important environmental risk factor for the development of skin cancers, including melanoma. Sun exposure and early sunburn during childhood are the principal causes of cutaneous melanoma insurgence in adults, with double the risk relative to a nonexposed population. Consequently, ultraviolet protection has long been recognized as an important measure to prevent such a malignancy...

The aim of this study was to evaluate the associations between menstrual and reproductive factors and thyroid cancer risk among Japanese women. A total 54 776 women aged 40-69 years completed a self-administered questionnaire, which included menstrual and reproductive history. During 1990-2012, 187 newly diagnosed cases of thyroid cancer were identified. Hazard ratios (HRs) and 95% confidence intervals (CIs) for menstrual and reproductive factors and incidence of thyroid cancer were estimated using Cox proportional hazards regression...

Some epidemiological studies suggest an association between genital use of talc powders and increased risk of ovarian cancer, but the evidence is not consistent. We performed a meta-analysis of epidemiological studies to formally evaluate this suspected association. A systematic search was conducted in Medline, Embase, and Scopus, leading to the identification of 24 case-control studies and three cohort studies, including 302 705 women with ovarian cancer. In the meta-analysis, we used a random-effect model to calculate summary estimates of the association between genital use of talc and occurrence of ovarian cancer...

Previous studies have reported an increased risk for certain types of cancer in the HIV-infected population. The aim of this study was to assess the risk for cancer in people with AIDS (PWA) in comparison with the general population in São Paulo (Brazil), between 1997 and 2012. A population-based registry linkage study was carried out to assess the risk for cancer, using a standardized incidence ratio (SIR) approach. A total of 480 102 person-years, of which 337 941 (70.4%) person-years were men, were included in the analysis...

X-ray repair cross-complementing group 1 (XRCC1) is one of the key components in the base excision repair pathway that repairs erroneous DNA lesions and removes nonbulky base adducts for the maintenance of genome integrity. Studies have revealed that differences in individual DNA repair capacity can impact the interindividual variation in cancer susceptibility, tumour aggressiveness and treatment response. The relationship between XRCC1 and sporadic colorectal cancer (CRC) susceptibility, which is hitherto inconclusive, has been explored in many association studies of different populations...

Whereas RAD51C mutations increase the relative risk for ovarian cancer (OC) to 5.88 (95% confidence interval=2.91-11.88, P=7.65×10), the associated risks for breast cancer (BC) remain largely unknown, as deleterious RAD51C alterations are extremely rare in BC-only families. Here, we report the results of a RAD51C mutational screening in a large series of German familial index patients negative for pathogenic BRCA1/2 mutations and the in-vitro characterization of two novel exonic RAD51C splice-site mutations...

Prostate cancer is the leading type of cancer diagnosed in men. Serum prostate-specific antigen levels and digital rectal exam are far from perfect when it comes to differentiation of patients with prostate cancer and benign prostatic hyperplasia. In this study, we attempt to determine whether amino acids can be used as prostate cancer biomarkers. Concentrations of derivatized amino acids and amines were quantified by liquid chromatography tandem mass spectrometry. A total of 100 urine samples from the two groups including samples provided before and after prostate massage were examined quantitatively for amino acid and amine concentrations with 50 urine samples collected from cancer patients and 50 samples from patients diagnosed with benign prostatic hyperplasia...

The incidence and mortality trends of oesophageal cancer are changing significantly across the world with considerable heterogeneity between sex, histological types, ethnic patterns and geographical distribution. Recent oesophageal cancer incidence and mortality trends have been analysed using data available from the WHO mortality database, the GLOBOCAN 2012 database and the Cancer Incidence in Five Continents database managed by the International Agency for Research on Cancer. Huge geographical variation is an epidemiological characteristic of oesophageal cancer, with the highest incidence rates observed in Eastern Asia and in Eastern and Southern Africa and the lowest rates observed in Western Africa...

Using a large, population-based survey, we assessed the levels and correlates of human papillomavirus (HPV) awareness among Scandinavian women after introduction of HPV vaccination. In 2011-2012, a random sample of women aged between 18 and 45 years from Denmark, Sweden and Norway received a questionnaire on lifestyle, health and HPV awareness. We included 47 895 women (response rate 60.6%) in our study. Country-specific and age-specific proportions of women who had heard of HPV in 2011-2012 (postvaccination survey) were compared with corresponding proportions in an identical survey from 2004-2005 (prevaccination survey, n=54 079, response rate 71...

Nasopharyngeal carcinoma (NPC) is a head and neck cancer that represents a major health burden in Southern China and Southeast Asia. Although the close association of NPC with Epstein-Barr virus (EBV) infection has been demonstrated, its exact role in the pathogenesis of this malignancy is still unclear. The expression of EBV-encoded microRNAs, especially BART miRNAs, which are encoded from the BamHI-A region of the viral genome, is detected at a high level in NPC. miRNAs are small noncoding mRNAs that can positively regulate the virus to ensure accurate expression of viral genomes and to modify the gene expression of host cells by negative regulation...

The aim of this study was to investigate the association between a history of prepregnancy obesity and a woman's future long-term risk for the development of female malignancies. A population-based study compared the incidence of long-term female malignancies in a cohort of consecutive women with and without a diagnosis of prepregnancy obesity. Deliveries occurred between the years 1988 and 2013, with a mean follow-up duration of 11.6 years. Women with known malignancies before the index pregnancy and known genetic predisposition for malignancy were excluded from the study...

The objective was to quantify thyroid cancer incidence and mortality trends in Portugal. The number of thyroid cancer cases and incidence rates were retrieved from the Regional Cancer Registries for the period 1989-2011. The number of deaths and mortality rates were obtained from the WHO cancer mortality database (1988-2003 and 2007-2012) and Statistics Portugal (2004-2006; 1988-2012 by region). Joinpoint regression of the standardized incidence and mortality rates was performed. A significant, rapid and continued increase in incidence was observed for both sexes in each of the Regional Cancer Registries, with annual per cent changes (APCs) ranging between 2 and 9...

This retrospective study examined whether human papillomavirus (HPV) type-specific viral load changes measured in two or three serial cervical smears are predictive for the natural evolution of HPV infections and correlate with histological grades of cervical intraepithelial neoplasia (CIN), allowing triage of HPV-positive women. A cervical histology database was used to select consecutive women with biopsy-proven CIN in 2012 who had at least two liquid-based cytology samples before the diagnosis of CIN. Before performing cytology, 18 different quantitative PCRs allowed HPV type-specific viral load measurement...

Alcohol consumption is associated with squamous cell carcinoma of the esophagus, but little is known about whether alcohol consumption is associated with adenocarcinoma of the esophagus and gastric cancer, which we attempt to clarify in this study. Individuals with alcohol use disorders were identified from the nation-wide Swedish Hospital Discharge Register and Outpatient Register, the Crime Register, and the Prescription Drug Register, and they were linked to the Swedish Cancer Registry to calculate standardized incidence ratios of esophageal and gastric cancers using those without alcohol use disorders (AUDs) as a reference...
