Kaiser Permanente Researcher Profiles

Lori C. Sakoda, MPH, PhD, is a research scientist of the Kaiser Permanente Northern California Division of Research and an affiliate investigator of the Division of Public Health Sciences at the Fred Hutchinson Cancer Research Center. Her research interests currently encompass identifying genetic and environmental determinants of risk and prognosis for cancer, particularly of the lung. She is also interested in understanding the basis for observed differences in cancer incidence and outcomes by sex and race/ethnicity.

Studies

Patterns, determinants, and outcomes of guideline-recommended imaging surveillance after surgical resection of early-stage lung cancer

High-quality evidence is limited on the utilization and outcomes of imaging surveillance after definitive surgery for early-stage lung cancer. This study examines patterns and factors associated with guideline-recommended imaging surveillance of lung cancer survivors, in addition to rates of new or recurrent lung cancer and mortality following surgical resection, before and after the implementation of a patient tracking system designed to support imaging surveillance.

Identifying Barriers to Lung Cancer Screening among Asian Americans

This study will identify key barriers to lung cancer screening as well as develop tailored strategies and materials to increase the uptake of lung cancer screening and smoking cessation services among Asian Americans.

Funder: Tobacco-Related Disease Research Program

What Factors Affect Time to Surgery for Lung Cancer and Moderate its Associations with Patient Outcomes

This study will determine factors that influence time to surgery and its associations with outcomes in patients with early-stage non-small cell lung cancer.
Investigator: Sakoda, Lori
Funder: TPMG Delivery Science Projects Program

Utilization and Impact of Extended-Interval Dosing of Immunotherapy on Outcomes in Patients with Locally Advanced NSCLC

This study will evaluate the utilization and dosing of durvalumab and associations with treatment outcomes among patients with unresectable stage III non-small cell lung cancer in an integrated health care system.
Investigator: Sakoda, Lori
Funder: AstraZeneca PLC

Multilevel Determinants of Racial/Ethnic Disparities in Lung Cancer Screening Utilization

Lung cancer screening has been underutilized nationally to date, with growing evidence suggesting that screening rates differ by race. This research aims to identify multilevel factors that influence disparities in utilization of lung cancer screening from eligibility determination to screening initiation.
Investigator: Sakoda, Lori
Funder: National Cancer Institute

Comparative Effectiveness of Pretreatment Lung Cancer Nodal Staging

The proposed project will determine whether a guideline-recommended nodal staging strategy is superior to a guideline-discordant nodal staging strategy, and whether a validated risk-based nodal staging strategy that reduces unnecessary biopsies is an equivalent alternative to a guideline-recommended nodal staging strategy in terms of patient outcomes and costs.

Disparities in REsults of Immune Checkpoint Inhibitor Treatment (DiRECT): A Prospective Cohort Study of Cancer Survivors Treated with anti-PD-1/anti-PD-L1 in a Community Oncology Setting

This project will establish a prospective cohort of white and Black cancer patients treated with immune checkpoint inhibitors, leveraging the NCI Community Oncology Research Program network infrastructure, to investigate racial differences in immune-related adverse events and their predictors, treatment delay and discontinuation, and short- and long-term patient outcomes.
Investigator: Sakoda, Lori
Funder: National Cancer Institute

Leveraging Diversity in Cancer Epidemiology Cohorts and Novel Methods to Improve Polygenic Risk Scores

Inadequate representation of diverse racial/ethnic populations in genetic studies is hindering the translational potential of polygenic risk scores (PRS) in cancer risk prediction. To address this shortcoming, we aim to construct and evaluate PRS for cancer and estimate the absolute risk of cancer explained by PRS and non-genetic factors across multiethnic populations.

Understanding Racial/Ethnic Disparities in Lung Cancer Screening Utilization

This study proposes to understand patterns and multilevel determinants of racial/ethnic disparities in Lung Cancer Screening utilization from 2017 onward at KPNC.

Assessing Adherence to Follow-Up Care After Low-Dose Computed Tomography Screening for Lung Cancer

With the recent implementation of lung cancer screening in community-based practice, little is currently known about utilization patterns and outcomes in patients following the initial low-dose computed tomography (CT) screening exam. The primary goals of this study are to 1) examine adherence to recommended follow-up based on initial low-dose CT screening exam results and 2) identify factors associated with adherence (versus non-adherence) to recommended follow-up.
Investigator: Sakoda, Lori
Funder: Northern California Community Benefit Programs

Evaluating a Risk Prediction Model for Lung Cancer

Screening with low-dose computed tomography (LDCT) presents an opportunity to improve early detection and reduce mortality from lung cancer. However, the potential harms of LDCT screening, including frequent false-positive findings that lead to unnecessary procedures and repeated radiation exposure, have raised concerns. Implementing targeted screening of persons at highest predicted risk for lung cancer may minimize such harms, but empirical evidence to support more personalized risk-based screening remains limited. This study presents a mentored career development plan encompassing training and research activities for establishing independence as a translational cancer epidemiologist, with a primary focus on early detection and management of lung cancer. The goal of the proposed research is to evaluate whether the most predictive and clinically-oriented risk model for lung cancer to date can be validated, extended and applied to aid decision-making about LDCT screening.
