Siteman Cancer Center Biostatistics Shared Resource

The Siteman Cancer Center (SCC) Biostatistics Shared Resource (BSR) fulfills a critical function by providing statistical support for the development and conduct of scientifically sound, innovative cancer research at SCC. Advances in biotechnologies and computing systems/software increasingly require specialized expertise and tools for sophisticated statistical methodologies. The overarching goal of the BSR is to provide a comprehensive, centralized, and accessible biostatistics support infrastructure for all phases of cancer research; from study development and design to ongoing monitoring and final analysis. BSR aims for this project period include:

Aim 1: Provide statistical collaboration, consultation, data management, and quantitative resources to clinical, pre-clinical, behavioral, and preventive research at SCC. The BSR designates a team of faculty and analysts to each SCC research program and disease area. Members of the team respond to researchers’ in-person and online requests for biostatistics services and collaborate with investigators on internal and external cancer-related grant applications. BSR faculty and analysts provide statistical support through the life cycle of a research project including: proposing/developing sound statistical designs (sample size calculations, research proposals, protocol development); supporting ongoing studies (randomization, interim analyses, safety and data monitoring, data management); devising and executing final data analyses (tables, statistical graphics); and preparing manuscript for publications.

Aim 2: Outreach to educate SCC researchers on the fundamentals of biostatistics, data management, and research rigor and reproducibility by enforcing statistical operating standards in research protocol reviews at SCC. BSR faculty are actively involved in training and mentoring students, residents, fellows, and junior faculty in statistical concepts through roles as course-masters or co-instructors in programs awarding formal degrees (e.g., MS, PhD, MD). BSR faculty apply statistical and rigor/reproducibility standards to SCC research to protect the scientific integrity of research and patient safety. This is accomplished at a study-specific level through their role on independent Data Safety and Monitoring Committees for SCC investigator-initiated, multi-site clinical trials. At an institutional level, BSR faculty apply these standards as reviewers on SCC’s Protocol Review and Monitoring Committee (PRMC), Siteman Investment Program (SIP) scientific study section, and the SCC Quality Assurance and Safety Monitoring Committee (QASMC). Key components of BSR’s protocol review include evaluation of study design, statistical power/sample size calculations, and futility/efficacy/toxicity monitoring rules. Statistical analysts follow standard operating procedures to ensure reproducibility.

Aim 3: Develop cutting-edge statistical methodologies tailored for specific collaborative research at SCC. Motivated by challenges that arise in clinical and translational research, BSR faculty members will develop novel statistical approaches to facilitate SCC members’ ability to effectively answer innovative and impactful scientific questions. In the next funding period, BSR expects further growth in capacity related to innovative study design and statistical methodology research. The BSR plans to add new expertise such as spatiotemporal statistical analysis and stepped wedge design (SWD), both of which are useful tools for community-based studies. The BSR has successfully recruited new faculty biostatisticians with expertise on biomarker analysis and electric health records (EHR). This will enhance statistical support for immunotherapeutic studies and also meet SCC members’ increasing needs in the area of EHR-based comparative effectiveness research.

NIH PUBLIC ACCESS POLICY: As of April 7, 2008, the NIH requires investigators with a publication using Siteman (or other NIH-funded) shared resources to submit (or have submitted for them) their final, peer reviewed manuscripts to PubMed Central(PMC) upon acceptance of publication, to be made publicly available within 12 months of publication. Many journals automatically submit these for authors, but Washington University also has assistance available through the Becker Medical Library.
