Background: Vigorous physical activity has been associated with lower risk of fatal prostate cancer. However, mechanisms contributing to this relationship are not understood.
Methods: We studied 117 men with prostate cancer in the University of North Carolina Cancer Survivorship Cohort (UNC CSC) who underwent radical prostatectomy and 101 radiation-treated patients with prostate cancer in FASTMAN.
Cancer Epidemiol Biomarkers Prev
December 2024
Background: Rapid growth in the number of US cancer survivors drives the need for ongoing research efforts to improve outcomes and experiences after cancer. In this study, we describe the University of North Carolina (UNC) Cancer Survivorship Cohort, a medical center-based cohort of adults with cancer that integrates medical record-abstracted cancer information, patient-reported outcomes, and biological specimens.
Methods: Participants ages 18+ were recruited from UNC oncology clinics between April 2010 and August 2016.
Purpose: Smoking is a modifiable lifestyle factor that has not been established as a prostate cancer risk factor, nor emphasized in prostate cancer prevention. Studies have shown that African American (AA) smokers have a poorer cancer prognosis than European Americans (EAs), while having a lower prevalence of heavy smoking. We examined the relationship between cigarette smoking and prostate cancer aggressiveness and assessed racial differences in smoking habits on the probability of high-aggressive prostate cancer.

We developed a time and motion (T&M) study within the Clinical Sequencing Evidence-Generating Research (CSER) consortium to address this gap, and herein describe challenges of conducting T&M studies within a research consortium and the approaches we developed to overcome them. CSER investigators created a subgroup to carry out the T&M study (authors).

Methods: The study population consisted of men (1010 Black; 1070 White) with incident prostate cancer from the baseline North Carolina-Louisiana Prostate Cancer (PCaP) cohort. Marital status at time of diagnosis and screening history were determined by self-report.
Background: Studies showed that folate and related single nucleotide polymorphisms (SNPs) could predict prostate cancer (PCa) risk. However, little is known about the interactions of folate-related SNPs associated with PCa aggressiveness. The study's objective is to evaluate SNP-SNP interactions among the DHFR 19-bp polymorphism and 10 SNPs in folate metabolism and the one-carbon metabolism pathway associated with PCa aggressiveness.

Objective: To discover common genetic variants contributing to the risk of PCa in men of African ancestry.
Design, Setting, And Participants: We conducted a meta-analysis of ten genome-wide association studies consisting of 19378 cases and 61620 controls of African ancestry.
Objective: Question prompt lists (QPLs) have been effective at increasing patient involvement and question asking in medical appointments, which is critical for shared decision making. We investigated whether pre-visit preparation (PVP), including a QPL, would increase question asking among caregivers of pediatric patients with undiagnosed, suspected genetic conditions.
Methods: Caregivers were randomized to receive the PVP before their appointment (n = 59) or not (control, n = 53).
Background: Increasing diversity in clinical trial participation is necessary to improve health outcomes and requires addressing existing social, structural, and geographic barriers. The Clinical Sequencing Evidence-Generating Research Consortium (CSER) included six research projects to enroll historically underrepresented/underserved (UR/US) populations in clinical genomics research. Delays and project re-designs emerged shortly after work began.

We sought to describe the pandemic's impact on research operations in the context of a clinical genomics research consortium that aimed to enroll a majority of participants from underrepresented populations. We interviewed (July to November 2020) and surveyed (May to August 2021) representatives of six projects in the Clinical Sequencing Evidence-Generating Research (CSER) consortium, which studies the implementation of genome sequencing in the clinical care of patients from populations that are underrepresented in genomics research or are medically underserved.

For those with undiagnosed conditions, the diagnostic odyssey can be long, expensive, and marked by uncertainty. We, therefore, sought to understand whether and how COVID-19 impacted the trajectory of children's care.

Reproductive health and sexual function are important to survivors of Adolescent and Young adult (AYA) cancers. We evaluated the prevalence of sexual dysfunction and factors associated with dysfunction using the Patient-Reported Outcomes Measurement Information System (PROMIS) sexual function (SexFS) measure in AYAs (15-39 years old at diagnosis) enrolled in a cancer survivorship cohort. Using a cross-sectional survey of a tertiary medical center-based cancer survivorship cohort, we determined the mean PROMIS SexFS v1.

However, associations between parental status and other aspects of the patient experience are not well understood. This study compared patient-reported outcomes of patients with and without minor children.

Individuals diagnosed with aggressive cancers are often at a greater risk of experiencing FT. The objectives of this study were to estimate FT among prostate cancer (PCa) survivors after 10-15 years of diagnosis, assess the relationship between PCa aggressiveness at diagnosis and FT, and examine whether current cancer treatment status mediates the relationship between PCa aggressiveness and FT.

However, adverse outcomes can occur many years after treatment. Herein, we aim to assess the utility of using claims data to identify prostate cancer progression 10-15 years after diagnosis.

While it is important to allow for natural variation in data collection protocols across research sites, it is also important to achieve interoperability between datasets in order to reap the full benefits of collaborative work. However, there are few standards to guide the data coordination process from project conception to completion.

We aim to develop optimal PRSs for the prediction of overall and estrogen receptor (ER) subtype-specific breast cancer risk in AA women. The AA dataset comprised 9235 cases and 10 184 controls from four genome-wide association study (GWAS) consortia and a GWAS study in Ghana.

Materials And Methods: This was a retrospective, cross-sectional study of HNSCC survivors surveyed at an outpatient oncology clinic from May 2012 through July 2016.
Results: Among 198 HNSCC survivors, 21% reported a MHD.
Purpose: To examine associations between recreational and occupational physical activity and prostate cancer aggressiveness in a population-based, case-only, incident prostate cancer study.
Methods: Data were analyzed from the cross-sectional North Carolina-Louisiana Prostate Cancer Project of African-American (n = 1,023) and European-American (n = 1,079) men newly diagnosed with prostate cancer (CaP). High-aggressive CaP was defined as Gleason sum ≥ 8, or prostate-specific antigen > 20 ng/ml, or Gleason sum ≥ 7 and clinical stage T3-T4.
Background: The overall survival rate of prostate cancer (PCa) has improved over the past decades. However, huge socioeconomic and racial disparities in overall and prostate cancer-specific mortality exist. The neighborhood-level factors including socioeconomic disadvantage and lack of access to care may contribute to disparities in cancer mortality.

Previous studies had identified inpatient-relevant International Classification of Diseases (ICD) codes that were possibly, probably, or definitely indicative of GDs. We assessed whether these codes identified GD-related inpatient, outpatient, and emergency department encounters among pediatric patients with suspected GDs from a previous study (the North Carolina Clinical Genomic Evaluation by Next-Generation Exome Sequencing [NCGENES] study).

Given the role of HOXB13 germline variation in prostate cancer, we investigated the association between HOXB13 X285K and prostate cancer risk in a large sample of 22 361 African ancestry men, including 11 688 prostate cancer cases. The risk allele was present only in men of West African ancestry, with an allele frequency in men that ranged from 0.
