Central Data Collection Center (CDCC) - Continued Follow-up of PLCO (Prostate, Lung, Colorectal, and Ovarian Cancer Screening Trial) Participants
This project involves ongoing followup of a randomized cancer screening trial of more than 20 years duration involving 74,000 females and 74,000 males aged 55-74 at entry at 10 sites around the country. Individuals in the control group received usual medical care. Individuals in the group randomized to screening received screening examinations for lung, and colo-rectal cancers and, depending on sex, either prostate or ovarian cancer. The screening trial was designed to determine whether: 1) screening with flexible sigmoidoscopy can reduce mortality from colo-rectal cancer; 2) screening with chest x-ray can reduce mortality from lung cancer; 3). screening men with digital rectal examination plus serum prostate-specific antigen can reduce mortality from prostate cancer; and, 4). screening women with CA 125 and transvaginal ultrasound can reduce mortality from ovarian cancer. Secondary objectives included: 1) to assess screening variables other than mortality for each of the interventions including sensitivity, specificity, and positive predictive values. 2) To assess incidence, stage, and survival experience of cancer cases. 3) To investigate the mortality predictive value of biologic and/or prognostic characterizations of tumor tissue as intermediate endpoints.

Community-Wide Weight Management Program
This project involves an annual community health challenge as part of the broader Heart of New Ulm Project (based in New Ulm, MN). The Community Challenge program will focus on weight management, and encourage participating residents to improve their nutrition and physical activity behaviors via an incentivized weigh-in system, telephonic coaching, and Internet self-help education.

CRN (Cancer Research Network) Pilot: Are 2 Jars Sufficient for Pathology Examination of Extended Core Prostate Biopsy?
The methodology for submitting extended core prostate biopsy (ECPB) varies widely. There is no currently recommended approach. At present, urologists may process tissue cores into between two and twelve jars. The difference in the number of jars can result in a difference of up to $1000 in costs to insurers. This pilot study will determine the patterns of processing ECPB tissue cores for examination, and determine associations between number of jars and key outcomes (e.g.: rates of prostate cancer detection, equivocal diagnoses). Researchers will accomplish this by using data collected clinically. The goal is to determine the variability in the patterns of number of pathology specimens per biopsy within two sites that have mixed insurance and practice patterns.

CRN4: Cancer Research Resources & Collaboration in Integrated Health Care Systems
The Cancer Research Network (CRN) is a consortium of research organizations within several non-profit health care delivery systems. Originally, CRN was focused on collaborative research made possible through integrated access to clinical datasets from the participating institutions. This new 5-year cycle uses a different funding mechanism and redefines the role of CRN as a broader resource for cancer researchers at large. The uniqueness of CRN as a cancer resource stems from: (1) the integrated access to clinical data for large, stable, and diverse patient populations that are available through the "parent" HMOs; and (2) the expertise of CRN researchers in conducting clinical cancer research involving large sets of clinical data. Through this, the NCI intends to promote further technical and methodological enhancements of CRN informatics infrastructure as well as efforts to facilitate access of non-CRN-affiliated investigators to CRN data and expertise. The goal is to increase the number and scope of research projects that are based on CRN data and the participation of CRN investigators on such projects. In addition to collaborations on projects funded outside of CRN, CRN will directly support pilot projects that may be initiated either by non-CRN-affiliated investigators or by CRN investigators.

Improving Diabetes Quality Reports for Persons with Multiple Chronic Conditions
The specific aim of this developmental work will be to evaluate the utility of existing health care quality reporting data from 3 healthcare systems in Wisconsin to support a more meaningful assessment of health care quality for subjects with multiple chronic conditions. The specific target for this initial work will be retrospective data from the pool of subjects with diagnosed diabetes. To view publications, click on links below:

Molecular Profiling of Ductal Carcinoma in Situ (DCIS) and Risk of Subsequent Invasive Breast
The goal of this multi-site study is to identify tumor markers for risk of progression from having DCIS to developing subsequent invasive breast cancer. This work follows extensive collaborative pilot work with Einstein College of Medicine and several other sites in the Cancer Research Network.

Preparing to Prioritize CVD (Cardiovascular Disease) Strategies in Rheumatoid Arthritis and Lupus: P2P-CVD
In the general population, attributable risks have been critical to identify U.S. and global preventive care priorities. However, attributable risks in rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE) are unknown. Filling the critical knowledge gap of attributable risks for CVD and death in RA and SLE will inform selecting the most important targets for a clinical intervention study to improve risk factor control and event-free survival.

Recently Completed Projects:
CVRN-Risks with ICD Placement and Outcomes in Kidney Disease (CVRN-RISK) Study
The aims of this bridge award were: 1) to understand the extent to which patients with heart failure with reduced left ventricular ejection fraction and concomitant reduced kidney function receive guideline-based primary prevention ICDs (implantable cardioverter defibrillators) compared with patients with preserved kidney function; 2) to clarify the effect of kidney function level on complications, hospitalization and death among heart failure patients who do and do not receive an ICD.

Anticoagulation Treatment and Long-Term Outcomes After Venous Thromboembolism
This project developed a cohort of adults with Venous Thromboembolism (VTE) that was used to answer numerous research questions about optimal VTE management within real-world practice settings. Treatment patterns and risk factors were used to predict recurrent VTE and major hemorrhagic complications.
