Identifying and Caring for Individuals With Inherited Cancer Syndrome

January 21, 2026 updated by: Jackie Shannon, OHSU Knight Cancer Institute

Approaches to Identify and Care for Individuals With Inherited Cancer Syndromes

This trial examines approaches to identify and care for individuals with inherited cancer syndrome. The purpose of this study is to offer no cost genetic testing to the general public. Researchers hope to learn the value of providing broad, public-wide testing for high risk cancer types (like hereditary breast and ovarian cancer or Lynch syndromes) instead of only testing people whose families are known to be high risk.

Detailed Description

PRIMARY OBJECTIVE:

I. Evaluate the effectiveness and sustainability of heritable cancer syndrome testing in two proposed screening populations compared to current guidelines.

SECONDARY OBJECTIVES:

I. Measure adherence to current guidelines for screening and prophylactic intervention of Cohorts B and C compared to Cohort A to show non-inferiority.

II. Measure the efficiency of cascade testing (defined as the ratio of family members screened over total possible) for Cohorts B and C compared to Cohort A to show non-inferiority.

III. Determine the costs and effectiveness, specifically quality adjusted life years (QALYs) associated with genetic screening models based on Cohorts B and C to estimate incremental cost-effectiveness ratio (ICER) and show that the costs per QALY are below the acceptable cost effectiveness threshold.

OUTLINE:

Patients undergo collection of saliva samples for genetic testing. If genetic test is positive, patients receive genetic counseling. Patients also complete a survey about cancer prevention, screening, and treatment.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Effectiveness and sustainability of heritable cancer syndrome testing in the two novel testing populations
Time Frame: Up to 5 years
Determine the costs and effectiveness, specifically Quality Adjusted Life Years (QALYs) associated with genetic screening models based on Cohorts B and C to estimate incremental cost-effectiveness ratio (ICER) and show that the costs per QALY are below the acceptable cost effectiveness threshold.
Up to 5 years
Adherence to standard of care for hereditary breast and ovarian cancer (HBOC) and Lynch syndromes
Time Frame: Up to 5 years
For Lynch syndrome we identify compliance as colonoscopy in past two years and bilateral salpingo-oophorectomy (BSO ) after child-bearing age. For HBOC, compliance is defined as breast imaging in past year or risk reducing surgery at any point in women.
Up to 5 years
Merged risk reduction strategies of bilateral salpingo-oophorectomy (BSO) or bilateral mastectomy and imaging
Time Frame: Up to 5 years
The merged risk reduction strategies of BSO or bilateral mastectomy and the imaging are treated as evidence of risk reducing behavior.
Up to 5 years
Cascade screening rate among Lynch or HBOC positive carriers
Time Frame: Up to 5 years
Will conduct negative binomial regression model and non-inferiority will be determined by rate ratio and its 95% confidence interval (CI).
Up to 5 years

Plan to Share Individual Participant Data (IPD)?

YES

IPD Plan Description

Data and samples collected under this protocol will be stored indefinitely in this study's repository for future research use. Participants must agree to future research use of their samples/data to participate in HOP.

Data/samples from participants who identify as American Indian/Alaska Native will be flagged within the HOP database so they can be excluded from data/sample releases for research purposes.

HOP has created a Data Access Committee (DAC) to review all requests for HOP data/samples. The DAC will review requests for feasibility and scientific merit before any data/samples are released.

OHSU investigators wishing to receive data from this study will sign a data release agreement documenting they will:

  • Meet all IRB requirements (IRB approval, exemption or nonhuman subjects research determination), as appropriate.
  • Use data only for the research described in their data request and/or IRB application/ protocol and obtain additional IRB approval if secondary studies are
