Evaluation of Multi-Cancer Early Detection Testing in a High-Risk Military Population: The Sentinel Study
- Conditions
- Cancer Diagnosis
- Interventions
- Other: GRAIL Galleri
- Registration Number
- NCT06523868
- Lead Sponsor
- Dana-Farber Cancer Institute
- Brief Summary
The purpose of this research study is to evaluate the possible benefits of an investigational, but commercially available Galleri multi-cancer early detection (MCED) blood test which is designed to detect many types of cancer early in veterans who have served in the military in active duty.
The name of the screening blood test being studied is:
-GRAIL Galleri MCED test
- Detailed Description
This research study aims to assess the performance of the Galleri multi-cancer early detection (MCED) screening test in a military population and to compare the number and types of cancers diagnosed using MCED testing versus standard of care. This research study will give doctors and participants results of Galleri® blood tests which is designed to detect many types of cancer.
The research study procedures including screening for eligibility, blood draws, questionnaires, and clinic visits.
Participation in this research study is expected to last for up to 1 year.
It is expected that about 1,500 people will take part in this research study.
The Department of Defense (DoD) is funding this study.

Group Intervention Description Galleri MCED Test GRAIL Galleri Enrolled participants will complete: * Baseline visit with blood draw and questionnaires * Return of study test result * Online post-test questionnaire * For a positive result, diagnostic work-up could include clinic visits, biopsy, surgery, imaging assessments such as ultrasound, Computed Tomography (CT) scans, or Magnetic Resonance Imaging (MRI) scans. If no cancer is found upon work up, a repeat MCED test may be ordered at the discretion of the principle investigator for up to 1 year from the initial MCED blood test. * Follow-up for a negative MCED blood test could include a repeat test ordered by the principle investigator for up to 1 year from the initial MCED test or a survey or phone call by study staff approximately 1 year after the initial MCED blood test. * Online post-diagnostic questionnaire.
- Primary Outcome Measures
Name Time Method Positive predictive value at 12 Months At 12 months Positive predictive value is defined as the proportion of participants with cancer diagnosis out of all participants with "signal detected" on GRAIL Galleri MCED test results.
Specificity Rate at 12 Months At 12 months Specificity is defined as the proportion of participants with "signal not detected" results out of all participants with no cancer diagnosis on GRAIL Galleri MCED test results.
Negative predictive value at 12 Months At 12 months Negative predictive value is defined as the proportion of participants with no cancer diagnosis out of all participants with "signal not detected" on GRAIL Galleri MCED test results.
Yield Rate at 12 Months At 12 months Yield rate is defined as the proportion of participants with "signal detected" out of all participants tested on GRAIL Galleri MCED test.
Number of Participants Needed to Screen at 12 months At 12 months Number Needed to Screen (NNS) is defined as the number of participants screened to detect a diagnosis of invasive cancer on the GRAIL Galleri MCED test.
- Secondary Outcome Measures
Name Time Method Cancer Detection Rate Comparison Up to 12 months Descriptive statistics will be used to summarize the number and types of cancers diagnosed by GRAIL Galleri MCED testing compared to Standard of Care (SOC) in matched population from the VA (separate IRB protocol).
Change in PROMIS Anxiety Short Form Score Baseline to 12 months Changes in anxiety following the GRAIL Galleri MCED test result and assessed by the Patient-Reported Outcome Measurement Information System (PROMIS) Emotional Distress Anxiety - Short Form 6a, which is a 6 item survey that is rated on a 5-point Likert scale with answers ranging from "Never" to "Always". The range of scoring is from 6 to 30 with higher scores indicating greater severity of anxiety.
Change in PROMIS Global Health Score Baseline to 12 months Changes in health-related quality of life following the GRAIL Galleri MCED test result and assessed by PROMIS Scale v1.2 - Global Health, a 10 item survey that is rated on a 5-point Likert scale with answers ranging from "Excellent/Completely/Never/None" to "Poor/Not at all/Always/Very Severe" and includes a pain average question rated on a scale of 0 "No Pain" to 10 "Worst Pain Imaginable." The range of scoring is from 9 to 45 with higher scores indicating higher quality of life.
Stage of Invasive Cancer Diagnosis Comparison Up to 12 months Descriptive statistics will be used to summarize the stages of invasive cancer that are diagnosed by GRAIL Galleri MCED testing assessed by medical record review compared to Standard of Care (SOC) in matched population from the VA (separate IRB protocol).
