While substantial advances in the identification of cytogenomic subtypes of childhood acute lymphoblastic leukemia (ALL) have been made in recent decades, epidemiologic research characterizing the etiologic heterogeneity of ALL by subtype has not kept pace. The purpose of this review is to summarize the current literature concerning subtype-specific epidemiologic risk factor associations with ALL subtype defined by immunophenotype (e.g. B-cell vs T-cell) and cytogenomics (including gross chromosomal events characterized by recurring numerical and structural abnormalities, along with cryptic balanced rearrangements, and focal gene deletions)...

BACKGROUND: In men with localized prostate cancer (PCa) who are undergoing radical prostatectomy (RP), it is uncertain whether their hormonal environment is associated with outcomes. The objective of the study was to examine the association between the steroid metabolome with prognostic factors and progression. PATIENTS AND METHODS: The prospective PROCURE cohort was recruited from 2007-2012, and comprises 1766 patients with localized PCa who provided blood samples prior to RP...

BACKGROUND: Bedford-Stuyvesant (BS) and Bushwick (BW) communities of Brooklyn, New York are the predominantly African-American and Hispanic neighborhoods within the main catchment area Memorial Sloan Kettering. Cancer is a leading cause of death, with a higher prostate (PCa) and colorectal cancer (CRC) mortality than New York City. Opportunity to design cancer interventions which leverage accessibility and acceptability of mobile health (mHealth) tools exists. METHODS: Cancer Health Impact Program (CHIP) was formed for this purpose...

BACKGROUND: While rural cancer patients encounter substantial barriers to care, they more often report receiving timely care than urban patients. We examined whether geographic distance, a contributor to urban-rural health disparities, differentially influences treatment initiation and completion among insured urban and rural cervical cancer patients. METHODS: We identified women diagnosed with cervical cancer from 2004-2013 from a statewide cancer registry linked to multi-payer, insurance claims...

BACKGROUND: Human microbiota have many functions that could contribute to cancer initiation and/or progression at local sites, yet the relation of the lung microbiota to lung cancer prognosis has not been studied. METHODS: In a pilot study, 16S rRNA gene sequencing was performed on paired lung tumor and remote normal samples from the same lobe/segment in 19 non-small cell lung cancer patients. We explored associations of tumor or normal tissue microbiome diversity and composition with recurrence-free and disease-free survival, and compared microbiome diversity and composition between paired tumor and normal samples...

BACKGROUND: The high rate of non-muscle invasive bladder cancer recurrence is a major challenge in patient management. microRNAs (miRNAs) functionally regulate tumor cell proliferation and invasion, and have strong potential as biomarkers, since they are robust to degradation. The objective of this project was to identify reproducible prognostic miRNAs in resected non-muscle invasive bladder tumor tissue that are predictive of the recurrent tumor phenotype. METHODS: We utilized patients diagnosed with primary non-muscle invasive bladder cancer in three independent cohorts for a biomarker discovery / validation approach...

BACKGROUND: Platelets are a critical element in coagulation and inflammation, and activated platelets are linked to cancer risk through diverse mechanisms. However, a causal relationship between platelets and risk of lung cancer remains unclear. METHODS: We performed single and combined multiple instrumental variable Mendelian Randomization(MR) analysis by an inverse-weighted (IVW) method, in addition to a series of sensitivity analyses. Summary data for associations between single nucleotide polymorphisms (SNPs) and platelet count is from a recent publication including 48,666 Caucasian Europeans and International Lung Cancer Consortium and Transdisciplinary Research in Cancer of the Lung data consisting of 29,266 cases and 56,450 controls analyze associations between candidate single nucleotide polymorphisms and lung cancer risk...

BACKGROUND: Allergic conditions may prevent some cancers by promoting immune surveillance. We examined associations of allergic rhinitis, asthma, and eczema with cancer risk among elderly Americans. METHODS: We used Surveillance, Epidemiology, and End Results (SEER)-Medicare linked data to perform a case-control study. Cases were individuals with first cancer diagnosed in SEER registries (1992-2013, ages 66-99; N=1,744,575). Cancer-free controls (N=100,000) were randomly selected from Medicare, matched on sex, age and selection year...

Background: Eligibility guidelines for genetic testing may be revisited, given technological advances, plummeting costs, and proposals for population mutation screening. A key property of eligibility criteria is the tradeoff between the number of mutation carriers identified versus population members tested. We assess the fractions of mutation carriers identified, versus women undergoing mutation testing, for BRCA1/2 founder mutation screening in U.S. Ashkenazi-Jewish women. Methods: BRCA1/2 carrier probabilities, based on personal/family history, were calculated using the risk-prediction tool BRCAPRO for 4,589 volunteers (102 mutation carriers) in the population-based Washington Ashkenazi Study...

In recent years, the National Cancer Institute (NCI) has focused on the impact that NCI-designated cancer centers have in reducing the cancer burden in their defined catchment areas. In 2016, NCI funded 15 cancer center support grant supplements to support cancer centers' abilities to better define and describe their catchment areas and needs to enhance cancer prevention and control. As part of this initiative, a working group developed standardized measures to capture demographic, social, knowledge, attitude, and behavioral factors to be included in the surveys fielded by all 15 cancer centers...

BACKGROUND: While particulate matter (PM) has not been consistently associated with breast cancer risk, two studies have reported harmful associations for breast cancer survival. We examined PM exposures and breast cancer survival in two US-based prospective cohort studies. METHODS: The Nurses' Health Study (NHS) and NHSII are cohorts with detailed data on medical history, lifestyle factors, and causes of death. Women with Stage I-III breast cancer (n=8,936) were followed through June 2014...

In May 2016, the National Cancer Institute (NCI) announced supplemental funding for NCI-designated cancer centers to conduct research to better characterize populations within cancer center catchment areas. The initiative was intended to support primary data collection efforts to better define and describe cancer center catchment areas using a multilevel population health framework. The long-term goal was to facilitate collaborations in which researchers, providers, public health practitioners, and nonprofit organizations could utilize the data to develop or expand applied cancer control research, planning, and implementation, with an emphasis on local health disparities and communication inequalities...

BACKGROUND: Evidence has suggested that aspirin reduces the incidence of several cancers, but these benefits may not occur with pancreatic cancer. METHODS: A 12-year nationwide longitudinal cohort merged with health checkup data were divided into "exposure ascertainment period" and "outcome ascertainment period" to avoid immortal time bias. The Daily Defined Dose system was used to indicate the drug exposure. RESULTS: We found no significant association between aspirin use and incident pancreatic cancer based on hazard ratio...

BACKGROUND: Elevated vitamin B12 levels (B12) are associated with increased short-term cancer risk. However, the implications for early cancer detection in primary care have not been assessed. METHODS: Individuals with plasma B12 measurements were sampled from The Health Improvement Network primary care database, United Kingdom. Persons with low B12 levels were excluded together with persons with cancer or B12 treatment before date of B12 measurement. Incident cancer was the outcome of interest and was identified through Read codes...
