Working with the BCSC

The BCSC conducts studies to assess and improve the delivery and quality of breast cancer screening and related outcomes. We collaborate with external investigators on funded research in this area.

As an alternative to collaboration, a set of downloadable public use datasets are freely available. No formal approval process or consultation with the BCSC is required to use these public-use datasets.


Submitting a Research Proposal & Collaborating with the BCSC

The BCSC shares custom datasets and conducts data analyses as part of funded research collaborations. In these collaborations you will work with one or more BCSC investigators and with the BCSC Statistical Coordinating Center (SCC).

If you have an idea for a research project with BCSC, you can contact the SCC at kpwa.scc@kp.org or a BCSC Investigator to explore the feasibility of the project and options for proceeding. Your BCSC contact will work with you to develop a brief concept proposal for review and approval by the BCSC Steering Committee. If your concept proposal is approved, your BCSC contact will then work with you to develop a full, more detailed, proposal for review and approval.

Interested investigators must obtain BCSC Steering Committee approval of their idea for research collaboration. Requests for custom BCSC datasets or analysis must meet these conditions:

  • The project does not compromise the confidentiality of patients, radiologists, or facilities.

  • The purpose of the study is research.

  • The BCSC PIs agree that the research question is of high scientific or public health value. 

  • The research proposal is sufficiently detailed to determine if the proposed analysis is feasible.

  • BCSC data are of sufficient quality and completeness to address the study question or aim.

  • Funding is available to support the collaboration of a BCSC investigator or investigators and to cover the costs of dataset preparation (and analysis if relevant) at the SCC.

  • There is no significant overlap with current or planned research.

  • Collaboration does not require sharing of cancer and vital status data from certain sites due to certain state law restrictions.

BCSC data are managed by the SCC and include information on demographics, risk factors, breast imaging and follow-up, and outcomes such as breast cancer. Because the data are associated with individuals, maintaining patient, provider, and facility confidentiality is a top priority. All personal identifiers for patients and providers have been removed from the data.


Guidelines for Developing Manuscripts

If a funded collaboration is approved, you will continue to work closely with your BCSC co-investigator(s) throughout the life of your project. The BCSC has a set of collaborative writing guidelines (PDF) to guide successful manuscript development for scientific papers.

To use BCSC data for publication, you must:

  • Collaborate with a BCSC investigator and the SCC on data preparation and analysis (unless solely using public-use data).

  • Acknowledge BCSC for its contributions to the manuscript (detailed guidelines will be provided).

  • Submit a final draft of the manuscript to the BCSC Steering Committee for approval before submission for peer review (unless solely using public-use data).


FAQs

If I have a project idea, who do I contact?

You can contact the SCC at kpwa.scc@kp.org, a BCSC registry Principal investigator, or other BCSC investigator. 

Does BCSC data fit my project?

To better understand the BCSC data, see the distributions of key variables and other information, tables, and graphs on the Data Elements & Questionnaires and Statistics pages. See also the BCSC Data Explorer data query tool. 

How representative are the BCSC data?

BCSC data reflect breast imaging practice as performed in the community in the U.S. Women in the BCSC reflect the population of U.S. women who undergo breast imaging. A comparison of BCSC with 2000 census data shows that BCSC sites are located in counties that contain slightly more than 5% of the nation's population. BCSC data reflect the national population in important respects:

What is the usual timeline from submitting a proposal to the SCC to receiving the data or analysis results?

The timeline varies depending on funding, the grant timeline, and staff availability at the SCC. In general, it takes about 3-8 months to provide data or analysis results after a project begins, depending on complexity. Projects with ongoing planned analyses will set their own timeline.
