Rising costs of cancer care have led to increased concerns about medical financial hardship for cancer survivors and their families in the United States. In this commentary, we provide an overview of research describing medical financial hardship and introduce a conceptual framework for identifying risk factors and research gaps at the patient and family, provider and care team, health care system, employer, and state and national policy levels. We then use this framework to highlight measurement and data infrastructure gaps related to hardship, summarize existing interventions to minimize hardship, and identify opportunities for future intervention efforts...

PURPOSE: Inflammation is linked to prostate cancer (PrCa) progression and is mediated by Nuclear Factor Kappa B (NFκB). Tristetraprolin is a key node of NFκB activation and we investigated its biological and prognostic role in lethal PrCa. METHODS: In vitro assays assessed the function of tristetraprolin and the association between low mRNA tristetraprolin levels and lethal PrCa (metastatic disease or death) was assessed across independent prostatectomy cohorts: (i) nested case-control studies from Health Professionals Follow-up Study and Physicians' Health Study, and (ii) prostatectomy samples from Cleveland Clinic, Mayo Clinic, Johns Hopkins and MSKCC...

BACKGROUND: There is little evidence of an association between cancer risk and long-term exposure to ambient particulate matter <10 μm (PM10) and ozone (O3) according to obesity and health-related behaviors. METHODS: In the 2012 Korean Community Health Survey, survey data on socioeconomic characteristics, health-related behaviors, and previous cancer history were collected from 100,867 participants. Daily average concentrations of PM10 and O3 (2003-2012) were obtained from the Korean Air Pollutants Emission Service...

BACKGROUND: Acrylamide, an industrial chemical and probable human carcinogen, can be formed in primarily carbohydrate-containing foods during high heat cooking or processing. Most epidemiological studies show no associations of dietary acrylamide intake with most cancer outcomes, but limited prospective evidence suggests a positive association with renal cell carcinoma (RCC). METHODS: In 1999, 102,154 men and women from the Cancer Prevention Study-II Nutrition Cohort completed a questionnaire on diet, lifestyle and cancer risk factors and were followed through June 30, 2013...

BACKGROUND: The impact of treatment delays on Prostate Cancer (PCa) specific outcomes remains ill-defined. This study investigates the effect of time to treatment on biochemical disease control after prostatectomy. METHODS: This retrospective study includes 1,807 patients who received a prostatectomy as a primary treatment at two large tertiary referral centers from 1987 - 2015. Multivariate cox model with restricted cubic spline were used to identify optimal time to receive treatment and estimate the risk of Biochemical recurrence...

Background: Cancer screening provides an opportunity to increase awareness of cancer-preventive lifestyle behaviors such as nonsmoking, physical activity, low alcohol consumption, and a healthy diet. We tested the effect of standardized, individually tailored written feedback (TF), and a standard leaflet (SL) on 1-year lifestyle behaviors in a colorectal cancer screening setting. Methods: A total of 3,642 men and women aged 50-74 years invited to sigmoidoscopy screening were randomly assigned to: (i) TF; (ii) SL for cancer-preventive lifestyle behaviors; or (iii) control...

BACKGROUND: The major mode of metabolism of nicotine is by hydroxylation via cytochrome P450 (CYP)2A6, but it can also undergo glucuronidation by UDP-glucuronosyltransferases and oxidation by flavin monooxygenases (FMOs). The goal of this study was to examine the potential importance of FMOs in nicotine metabolism and assess the potential impact of missense polymorphisms in active FMOs on nicotine-N'-oxide formation. METHODS: Urine samples from 106 current Chinese smokers were analyzed for nicotine metabolites by mass spectrometry (MS)...

BACKGROUND: Because of limited stability and sensitivity, circulating miRNAs as noninvasive biomarkers has not so far been used for early diagnosis and prognosis of non-small cell lung cancer (NSCLC) in clinic. Therefore, it is still imperative to find more reliable biomarker(s). METHODS: We performed one of most sensitive RT-qPCR assays, S-Poly(T) Plus to selected differently expressed miRNAs from genome-wide miRNA profiling. miRNA candidates were validated through a three-phase selection and two-validation process with 437 NSCLC cases and 415 controls...

BACKGROUND: Lung cancer is the leading cause of cancer mortality in the United States (US). Squamous cell carcinoma (SQCC) represents 22.6% of all lung cancers nationally, and 26.4% in Appalachian Kentucky (AppKY), where death from lung cancer is exceptionally high. The Cancer Genome Atlas (TCGA) characterized genetic alterations in lung SQCC, but this cohort did not focus on AppKY residents. METHODS: Whole exome sequencing was performed on tumor and normal DNA samples from 51 lung SQCC subjects from AppKY...

BACKGROUND: Research reproducibility is vital for translation of epidemiologic findings. However, repeated studies of the same question may be undertaken without enhancing existing knowledge. To identify settings in which additional research is or is not warranted, we adapted research synthesis metrics to determine number of additional observational studies needed to change the inference from an existing meta-analysis. METHODS: The fail-safe number (FSN) estimates number of additional studies of average weight and null effect needed to drive a statistically significant meta-analysis to null (P≥0...

Background: NSAID use may affect ovarian cancer risk via prostaglandin synthesis and tumor-associated macrophage (TAM) infiltration. We evaluated if associations between aspirin or non-aspirin NSAID use and ovarian cancer risk differed by tumor expression of prostaglandin-related (COX1, COX2) and TAM-related (CD68, CD163) markers. Methods: We evaluated cases and matched controls from the Nurses' Health Study (NHS), NHSII, and New England Case-Control Study (NECC). Cases with IHC data on COX1 and COX2 ( n = 532) or CD68 and CD163 ( n = 530) were included...

BACKGROUND: In mice, bacteria from the mouth can translocate to the pancreas and impact pancreatic cancer progression. In humans, oral bacteria associated with periodontal disease have been linked to pancreatic cancer risk. It is not known if DNA bacterial profiles in the pancreas and duodenum are similar within individuals. METHODS: Tissue samples were obtained from 50 subjects with pancreatic cancer or other conditions requiring foregut surgery at the Rhode Island Hospital (RIH), and from thirty-four organs obtained from the National Disease Research Interchange...

BACKGROUND: An elevated erythrocyte sedimentation rate (ESR) may be a marker of occult cancer. METHODS: We linked Danish medical databases to examine cancer incidence in patients with a first-time hospital contact for elevated ESR during 1980-2013. We calculated standardized incidence ratios (SIRs) of cancer compared with the general population, and comorbidity-adjusted hazard ratios (aHRs) versus matched population comparisons without elevated ESR. We also compared survival among cancer patients with elevated ESR with that among cancer patients without elevated ESR...
