简要总结

This is a multi-center, single arm trial to evaluate the cancer detection rate of supplemental screening magnetic resonance imaging (MRI) in participants who are high-risk by Mirai-MRI assessment. Mirai is an accurate cancer risk model based on full-resolution mammograms.

详细描述

PRIMARY OBJECTIVE:

I. To estimate the cancer detection rate (CDR) of supplemental screening breast MRI in participants who are high-risk by the Mirai model

SECONDARY OBJECTIVES:

I. To estimate the CDR of supplemental screening breast MRI in participants with high Mirai risk and low (<20%) lifetime Tyrer-Cuzick (TC) risk.

II. To compare the CDR of supplemental screening breast MRI in participants with high Mirai risk and high (≥ 20%) lifetime TC risk versus CDR in participants with high Mirai risk and low (<20%) lifetime TC risk.

入选标准

  • All asymptomatic participants assigned female at birth, ages 40-89 years old with screening mammography assessed as Breast Imaging Reporting and Data System (BI-RADS) 1, BI-RADS 2, or initial BI-RADS 0 with subsequent diagnostic mammogram assessed as BI-RADS 1 or BI-RADS
  • Screening mammogram assessed as high-risk by Mirai (top 3 percentile of 2-year risk).
  • Availability of a routine screening mammogram report, along with a subsequent diagnostic mammogram report if applicable, and access to the corresponding Digital Imaging and Communications in Medicine (DICOM) images.
  • Ability to understand and the willingness to sign a written informed consent document.

排除标准

  • Screening mammogram that is assessed as BI-RADS 0 for technical recall.
  • Contraindications for MRI:
  • Metallic foreign body in the eye.
  • MRI unsafe implants and/or medical devices.
  • Adverse reaction to a (gadolinium-based) contrast agent in the past.
  • Pregnant women.
  • Claustrophobia.
  • Exceeds site specific size and/or weight limit for MRI.
  • If the participant meets site-specific criteria for screening estimated glomerular filtration rate (eGFR) prior to MRI, participants with severely impaired renal function (GFR < 30 mL/min) will be excluded. According to University of California, San Francisco's policy for MRI with contrast (gadolinium-containing), serum creatinine with calculation of eGFR should be obtained within 6 weeks of the MRI study for participants with any of the following risk factors:
  • History of "kidney disease" as an adult, including renal tumor or transplant.
  • Diabetes treated with insulin or other prescribed medications.
  • Hypertension (high blood pressure) requiring medication.
  • Multiple myeloma.
  • Solid organ transplant.
  • History of severe hepatic disease/liver transplant/pending liver transplant.

结局指标

主要结局

时间窗: Up to 1 year

The CDR is defined as the number of breast cancers identified per 1,000 magnetic resonance imaging (MRI) screening examinations performed 1 year following supplemental screening MRI.

次要结局

  • Comparison of CDR in low and high TC risk groups(Up to 1 year)
  • Proportion of participants with lymph node involvement detected in supplemental imaging(Up to 1 year)
  • CDR of participants designated as low risk using the Tyrer-Cuzick (TC) criteria(Up to 1 year)
  • Positive predictive value of supplemental MRI screening and BI-RADS Score (PPV1)(Up to 1 year)
  • Positive predictive value of supplemental MRI screening recommending histological or surgical follow-up (PPV2)(Up to 1 year)
  • Positive predictive value of biopsies resulting in histological diagnosis (PPV3)(Up to 1 year)
  • False Positive Rate (FPR)(Up to 1 year)
  • Mean tumor size detected in supplemental imaging(Up to 1 year)
  • Correlation between menopausal status and CDR(Up to 1 year)
  • Frequency of tumor stage detected in supplemental imaging(Up to 1 year)
  • Proportion of participants with Ki-67 expressed biomarker(Up to 1 year)
  • Correlation between race/ethnicity and CDR(Up to 1 year)
  • Correlation between hormonal status and CDR(Up to 1 year)
  • Correlation between breast density and CDR(Up to 1 year)
  • Correlation between family history of cancer and CDR(Up to 1 year)
