Kaiser Permanente studies at ASCO Annual Meeting highlight advances in cancer care delivery

Studies draw on KP’s experience as one of the largest cancer care providers in the U.S. and a top enroller in NCI-sponsored clinical trials

Kaiser Permanente

OAKLAND, CAMAY 26, 2022 – Kaiser Permanente, which cares for more than 500,000 cancer patients every year, will present 10 studies at the 2022 ASCO Annual Meeting (June 3-7, 2022 in Chicago) that offer new insights into how to improve the delivery of cancer care so that more patients benefit. Kaiser Permanente researchers contributed to an additional 12 studies focused on novel treatment advances, and will be featured in two educational sessions: one exploring the future of real-world data versus clinical trials and another on aging and social justice. All Kaiser Permanente abstracts were publicly posted today at

As a top enroller in National Cancer Institute (NCI)-sponsored clinical trials, Kaiser Permanente currently has more than 200 active studies, coupled with decades of experience putting care improvements into practice that reduce health disparities across a large, integrated health care system.

“We’re excited to bring our expertise and research to ASCO 2022,” said Tatjana Kolevska, MD, medical director for the Kaiser Permanente National Cancer Excellence Program. “Kaiser Permanente has a longstanding commitment to equity in cancer care, combined with diverse clinical trial participation, and a strong track record of reducing cancer care disparities.”



Four studies examine ways to avert early hospitalization and death in older cancer patients:

  1. Geriatric risk and toxicity assessments can predict adverse outcomes in older cancer patients (≥65) with newly diagnosed cancer: This pilot study involving 1,598 patents at select Kaiser Permanente community-based clinics affirms that increasing age is associated with higher G8/CARG risk, reinforcing the importance of conducting these assessments at the time of initial cancer diagnosis, in line with ASCO and NCCN recommendations.
  2. Nurse navigators can help address an urgent, unmet need for greater completion of pre-chemotherapy geriatric assessments and toxicity screenings: Nurse navigators across seven hematology-oncology community clinics dramatically increased uptake of pre-chemo screening tools designed to predict early hospitalization and death. While outside studies show a 20-35% completion rates of G8 and CARG when administered by a physician, 79% of KP patients completed the G8 screening (N=1,372), while 92% completed the CARG toxicity tool (N=563), highlighting their utility in predicting adverse clinical outcomes among a growing population of older adults with cancer.
  3. Digital caregiver reports can provide early signs of adverse outcomes in cancer patients: Following 52 patient-caregiver pairs, researchers found that caregiver reports accurately predicted ED/hospitalizations, mortality, and hospice referral among adult solid cancer patients receiving intravenous systemic therapies. Kaiser Permanente’s digital app, TOGETHERCareTM, allowed caregivers to report patient symptoms and physical functions in real time.
  4. Eastern Cooperative Oncology Group Performance Status scale a strong predictor of emergency department visits, hospitalizations, and mortality: This retrospective study, involving 21,730 adults receiving intravenous systemic cancer therapy at 18 Kaiser Permanente locations in Northern California, found that patients with higher ECOG-PS scores (3-4; out of a range of 0-4) were at increased risk of ED admission. African American, male, and older patients, as well as patients with Stage IV cancer, had higher ECOG-PS levels, suggesting that the ECOG-PS scale can better predict clinical outcomes among certain patient groups.

Additional featured research from Kaiser Permanente-led studies:

  1. Compared to clinical breast exam, imaging detects vast majority of secondary breast cancers in DCIS patients: Amid increased incidence of the earliest, pre-invasive stage of breast cancer, ductal carcinoma in situ (DCIS), more women are undergoing post-treatment surveillance for secondary breast cancers. Kaiser Permanente surveyed 1,561 female DCIS patients diagnosed between January 1, 2008 and January 1, 2011. Only 2% of secondary breast cancers were detected by a clinical breast exam, while 77% of 137 cases in the cohort. Results can help inform future guidelines designed to detect secondary breast cancer in DCIS patients.
  2. Bevacizumab-awwb is a safe and effective option to treat metastatic colorectal cancer: This observational study, following 1,445 metastatic colorectal cancer patients within a multi-state integrated healthcare system, found that patients receiving biosimilar bevacizumab-awwb had similar outcomes of overall survival (73%) compared to patients receiving bevacizumab (73%). Findings reinforce that bevacizumab-awwb is a safe and effective alternative treatment option.
