Research overview

Cancer is complex and can be a devastating diagnosis for individuals and their families. Our researchers work to improve cancer control on many levels, from prevention and screening through treatment and survivorship.

Kaiser Permanente Washington Health Research Institute (KPWHRI) has been studying how to provide life-saving breast cancer screening since 1986. In a novel initiative, researchers used a computer-based registry and collaborations with organizations across the U.S. before electronic health records existed and multi-site studies were common. The program ultimately led to a rich portfolio of studies not only on breast cancer, but also on colorectal, blood, cervical, lung, and thyroid cancers.

“Decades later, Kaiser Permanente Washington is just as committed to developing and evaluating innovations in cancer care,” said Karen Wernli, PhD, KPWHRI associate investigator.

The core of KPWHRI cancer research lies in its participation in many collaborative networks and programs. “Collaboration increases the power of Kaiser Permanente studies and helps us learn from different populations and health care settings,” said Senior Investigator Jessica Chubak, PhD. Examples of these networks include:

Breast Cancer Surveillance Consortium (BCSC)
The BCSC identifies strategies that detect aggressive breast cancer early, minimize harms, and reach diverse communities. Results help policymakers and health systems improve breast cancer screening and surveillance outcomes. The Kaiser Permanente Washington Breast Imaging Registry contributes to this national effort and the BCSC Statistical Coordinating Center resides at KPWHRI.

Population-based Research to Optimize the Screening Process (PROSPR)
The PROSPR national consortium conducts research to improve screening for cervical, colorectal, and lung cancers. PROSPR results will help optimize and tailor screening for different subgroups of the population.

Kaiser Permanente Research Bank (KPRB) Cancer Cohort
The KPRB Cancer Cohort is a national resource for understanding genetic, lifestyle, and environmental factors that contribute to cancer etiology and survival. Electronic health record data, stored tissue specimens, detailed treatment data, and the ability to follow patients for recurrence and mortality are accelerating progress toward improved cancer care.

Some of the cancer research group’s current studies include:
