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
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.

A multi-cancer early detection (MCED) blood test.
Dana-Farber Cancer Institute
Boston, Massachusetts, United States
RECRUITINGPositive predictive value 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.
Time frame: At 12 months
Negative predictive value 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.
Time frame: At 12 months
Specificity Rate 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.
Time frame: At 12 months
Yield Rate 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.
Time frame: At 12 months
Number of Participants Needed to Screen 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.
Time frame: At 12 months
Cancer Detection Rate Comparison
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).
Time frame: Up to 12 months

Stage of Invasive Cancer Diagnosis Comparison
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).
Time frame: Up to 12 months
Change in PROMIS Anxiety Short Form Score
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.
Time frame: Baseline to 12 months
Change in PROMIS Global Health Score
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.
Time frame: Baseline to 12 months
