Information provided by (Responsible Party):
GRAIL is using high-intensity sequencing of circulating cell-free nucleic acids (cfNAs) to develop blood tests to detect cancer early. The purpose of this study is to train and validate an assay to detect invasive breast cancer in patients undergoing mammography.

Primary Outcome Measures:
  • Diagnosis of invasive breast cancer among women undergoing mammography [ Time Frame: 30 Months Estimated ]
    Clinically annotated plasma samples from participants will undergo high-intensity sequencing to characterize cfNA profiles.

Estimated Enrollment: 120000
Actual Study Start Date: February 28, 2017
Estimated Study Completion Date: May 2025
Estimated Primary Completion Date: July 2019 (Final data collection date for primary outcome measure)
Prospective Cohort
This is a prospectively enrolling cohort study with a pre-specified molecular analysis plan. A stratified case-cohort design will be employed to select cancer cases and non-cancer subjects who will be assayed. All cases of cancer (breast and non-breast cancer) will be selected. A random subset of the overall study cohort will also be selected.

Detailed Description:
Detection of early stage cancer may be possible through analysis of circulating cell-free nucleic acids (cfNAs) shed into the blood by tumors. GRAIL is using high-intensity sequencing (based on broad genomic coverage and deep sequencing) of cfNAs, combined with machine learning, to develop blood tests to detect cancer early. The purpose of this prospective, multi-center, observational cohort study is to train and validate an assay for the early detection of breast cancer. The study will collect blood samples from participants within 28 days of their screening mammogram. For participants who receive a cancer diagnosis during the study, tissue samples will be collected.

Sampling Method:   Non-Probability Sample
Study Population
This study seeks to enroll 120,000 women receiving screening mammography and associated medical care from participating study centers.

Inclusion Criteria:

  1. Patient has an appointment for screening mammography, as referred or recommended by a health care provider.
  2. Screening mammogram is received at same facility within 28 days of blood draw (i.e. blood may be drawn up to 28 days before or 28 days after the screening mammogram).
  3. Provides informed consent in English or Spanish. Understands the protocol and its requirements, risks, and discomforts.
  4. Provides consent to participate in long-term follow-up, such as contact via study portal, mail, or phone, for further self-reported information regarding cancer diagnoses, change to health plan or residential status, or request for additional blood draws and linkage to state state cancer registries and administrative databases.

Exclusion Criteria:

  1. Inability on the part of the patient to understand the informed consent or be compliant with the protocol.
  2. Breast biopsy to evaluate abnormal breast imaging results has occurred prior to a planned research blood draw.
