SBI Keynote and Honorees, New Study

by

Society of Breast Imaging (SBI)
The Society of Breast Imaging’s 40th annual symposium begins next week! Join Keynote Speaker, DBI’s JoAnn Pushkin, MAB member Dr. Paula Gordon, MAB past member Dr. Georgia Spear and others, for the Keynote Advocacy Session: The Changes We Fought for and the Patients Who Benefitted (April 24th at 11:10am).

SBI Honorees
Congratulations to SBI 2025 Gold Medalist Dr. Paula Gordon and to 2025 SBI Honorary Fellow JoAnn Pushkin.

New Study
Caumo et al reported on the first screen results in the Italian Risk-Based Breast Screening study (RIBBS) which personalizes screening based on risk and breast density. Women age 45 with high Volpara volumetric breast density > 25% were invited for screening tomosynthesis (DBT) plus supplemental ultrasound (US). Women with a high lifetime breast cancer risk (>30% by Tyrer-Cuzick model) were recommended for supplemental screening MRI instead of US regardless of breast density. This study group was compared to a control group receiving 2D-digital mammography.

  • The use of DBT plus US in high-density women was associated with a decrease in recalls and an increase in biopsies.1
  • Detection of small invasive breast cancers doubled in the group of women invited to additional screening and was associated with increased detection of DCIS and grade 3 invasive cancers.2
  • Regardless of density, low risk women were recommended for biennial screening, while intermediate- and high-risk women were recommended for annual screening.
  • The stratification criteria effectively identified subpopulations with different breast cancer prevalence who may benefit from different screening protocols.3

1 Among 10,269 women enrolled in the prospective study, recall rates decreased by 50% while biopsy rates increased 80% in high-density subgroups receiving DBT plus US compared to the control group having only DBT.

2 There was 2.3-fold higher detection of invasive cancers between 1.1 and 2 cm in the intervention group and 2.4-fold higher grade 3 invasive cancer rates, both P<.05. The intermediate-risk group (lifetime risk > 17% and ≤ 30%) with increased breast density showed a 4.6-fold higher prevalence of breast cancer compared to those with low risk and low density.

3 Interval cancer rates have not yet been determined due to insufficient follow-up.

New European Medical Supporter, Just Published

by

New European Medical Supporter
DenseBreast-info/Europe announces our new European Supporter Dr. Fleur Kilburn-Toppin. She is a Consultant Breast Radiologist and Director of Breast screening at Cambridge University Hospital, UK. She is also on the Executive Board and Chair of the Educational committee for the European Society for Breast imaging. Her research interests are on a variety of aspects of breast imaging including breast density.  Welcome!

Just Published
Gordon et al reported an audit of biopsies prompted by technologist-performed handheld screening ultrasound (US) in women with dense breasts in British Columbia.  Women received either annual or biennial digital 2D mammography, with screening US midway in the interval.

  • Screening US significantly increased the rate of biopsies performed.1
  • Screening improved cancer detection2, most of which were early breast cancer.3
  • The majority of women with US-detected cancer had heterogeneously dense breasts4and half had no other risk factors.
  • Recall rates could not be assessed.

In Canada, 12 of 13 provinces have screening mammography programs. Screening US is currently available only by request in 5 of 12 provinces. The yield of screening US in this study was much higher than in a prospective study in the USA with concurrent annual tomosynthesis.

1 Among a mix of 5257 incidence and prevalence screening US examinations, 247 (4.7%) women had biopsy prompted by US.
2 32 cancers were identified in 32 women, for an incremental cancer detection rate of 6.1/1000 and PPV3 of biopsies of 32/281 (11.4%) at the lesion level.
3 Of the 32 cancers, 26 (82%) were invasive with mean size 13 mm (range 5 to over 40), and 24/26 (92%) were node negative. 
4 Of the 32 women with US-detected cancer, 27 (84%) had heterogeneously dense breasts and 5 had extremely dense breasts.

More State Insurance Bills, Canadian Task Force

by

U.S. State Insurance Bills
Bill introductions continue to roll in for expanded insurance coverage for breast imaging. New this week:

Canadian Task Force PAUSED
Canada’s Minster of Health announced a temporary pause of the work of the Canadian Task Force on Preventative Health Care. The External Expert Review of the Canadian Task Force on Preventive Health Care is studying the Task Force’s governance, mandate, and processes. This review was prompted, in part, by “important feedback directly from Canadians and key leaders in the area who raise their concerns on the existing guidance and process of the Task Force.” Much credit goes to Dense Breasts Canada who fought a 7-year battle for a revision and to Drs. Paula Gordon, Jean Seely, Anna Wilkinson, and Martin Yaffe for their research and advocacy, and to Dr. Sheila Appavoo for leading a coalition of specialists.

European Screening Flowchart, AI Risk Assessment Software Study

Newly Updated / European Resource
Just out, DenseBreast-info/Europe’s updated flowchart, European Screening Decision Support Tool.

New Study
Since the publication of the 2007 guideline from the American Cancer Society, one barrier to implementing supplemental screening MRI in high-risk women has been performing risk assessment. With expanding indications for MRI for women at intermediate risk (including many women with dense breasts), MRI capacity has become another major barrier.  Just out in Radiology, van Winkel and colleagues in the Netherlands applied AI risk assessment software (Transpara, v. 1.7.0, ScreenPoint Medical) to the mammograms of 2819 women at intermediate risk who underwent screening MRI.  An AI threshold that identified the top half of women at higher risk of cancer present identified:

  • All 18 (100%) women with mammographically detected cancer
  • 24/28 (86%) with MRI-detected cancer
  • 13/19 (68%) with mammographically occult cancer
  • This could have cut the number of MRI examinations in half (1409) (with AUC 0.72)

Other software tools such as iCAD, Mirai, and Mia have shown similarly good performance in identifying women likely to have mammographically occult cancer who might benefit from screening MRI.

New State Insurance Bills, New Review Article

State Insurance Bills

Newly introduced state insurance bills to cover expanded breast imaging include the following:

Review Article

A recent review of supplemental screening in women with extremely dense breasts by Sitges and Mann concludes that 2D mammograms alone are inadequate screening, with more cancers missed, higher risk, and high rates of clinically detected cancers in the interval after a negative screen.  Figure 2 (below) from their paper shows the added cancer yields from each type of supplemental screening. They also summarize recommendations from international societies, including the recommendations from the ACR to include annual MRI for women with dense breasts, or CEM or ultrasound if MRI is not possible, starting at age 40 (or earlier if there are other risk factors).

Updated Federal Breast Screening Recommendations

by

NEWS: Breast Cancer Screening – Updated Federal Recommendations
On 12/30/24, the Health Resources and Services Administration (HRSA) issued a notice, Update to the Health Resources and Services Administration’s (HRSA) Women’s Preventative Service Guidelines. One of the Guideline revisions relates specifically to “Breast Cancer Screening for Women at Average Risk” and will take effect in January 2026 for applicable insurance plans*.

Some details:

  • “Women may require additional imaging to complete the screening process or to address findings on the initial screening mammography. If additional imaging (e.g., magnetic resonance imaging (MRI), ultrasound, mammography) and pathology evaluation are indicated, these services also are recommended to complete the screening process for malignancies.”
  • “While there are currently no randomized controlled trials to support separate recommendations for women with dense breasts, the updated clinical recommendation supports additional testing to complete initial screening, if needed, which may be more common for women with dense breasts”
  • “Non-grandfathered group health plans and health insurance issuers offering group or individual health insurance coverage must cover without cost-sharing the services and screenings listed on the updated Women’s Preventive Services Guidelines for plan years (in the individual market, policy years) that begin 1 year after this date. Thus, for most plans, this update will take effect ….in 2026.”

*Clarification is pending on whether self-funded plans, federal plans (e.g., Medicare, VHA, TRICARE) and/or ERISA plans (a private sector retirement or health plan that’s governed by the Employee Retirement Income Security Act) are included. We will share more information as we learn it.

Flowchart Update; CEM Study

by

Who Needs More Screening? Flowchart
This popular screening decision support tool for health providers has just been updated, view it HERE.

CEM Study
A retrospective, single-institution study at Memorial Sloan Kettering Cancer Center reported results of several rounds of screening contrast-enhanced mammography (CEM) in 609 women with extremely dense breasts, most of whom also had other risks for breast cancer. Compared to low-energy images (similar to a standard 2D full-field digital mammogram), contrast enhancement:

  • Increased cancer detection1
  • Decreased specificity, which improved at follow up exams when prior images were available for comparison2

As summarized in an accompanying editorial by Marc Lobbes, MD, PhD, these results support the use of CEM as a safe and effective screening tool for women with dense breasts.

1The cancer detection rate after contrast enhancement vs. low-energy images was 12.7 per 1000 (16/1264) vs. 4.0 per 1000 (5/1264) for an incremental cancer detection rate of 8.7 per 1000 screens (11/1264). The sensitivity after contrast enhancement vs. the low energy images was 88.9% (95% CI: 65.3, 98.6) vs. 27.8% (95% CI: 9.7, 53.5) (P = .003).

2The specificity after contrast enhancement vs. low-energy images was 88.9% vs. 96.2%, P < .001. Specificity at follow-up improved to 90.7% (95% CI: 88.5, 92.7; P = .01).

Research Round Up

by

AI vs. ultrasound
A single-institution, retrospective study of 5707 women with dense breasts and a negative mammogram at Seoul National University Hospital found that adding artificial intelligence (AI) is less effective than adding screening ultrasound (US). Supplemental physician-performed whole breast handheld US found more cancers than 2D digital mammography (MG) plus AI with an added incremental cancer detection rate of 2.2 (95% CI 1.1, 3.8) per 1000 screens. All 12 additional cancers seen by US alone were invasive and node negative. While sensitivity was higher for MG plus US than for MG plus AI  (97% vs. 60%, p=.002), specificity was lower (77.6% vs. 95.3%, p<.001). Further research is needed to better understand the role of AI in women with dense breasts.

Contrast-enhanced mammography
Patel and colleagues at Mayo Clinic, Scottsdale, AZ, reported results of the first round of screening contrast-enhanced mammography (CEM) after negative digital breast tomosynthesis (DBT) in 460 women at elevated risk, of whom 408 (89%) had dense breasts. CEM prompted biopsy in 37 (8.0%) women, with 11/37 (30%) found to have cancer, for a supplemental cancer detection rate of 24/1000. Specificity of CEM was 393/449 (87.5%). Of 14 total malignancies found, 10 were invasive, median size 9 mm, all node negative; there was one interval cancer found on screening MRI.

NEW Technology Tab Table

by

New – updated table for health professionals, Cancer Detection by Screening Method in Dense Breasts. By modality, the table shows results of supplemental screening after mammography in dense breasts in first and subsequent rounds of screening. It includes the added cancer detection benefit, change in false positive recall rate, and availability.

As a reminder, patient content on the topic is also available in DBI’s new very popular page Screening Tests After a Mammogram.

New Studies

Recently Published

Two recently published studies that might be of interest –

Patient Experience of Women with Dense Breasts Undergoing Screening Contrast-Enhanced Mammography:
A study from the University of Virginia, co-authored by DBI medical advisory board member Dr. Jennifer Harvey, found that most women with dense breasts who underwent contrast-enhanced mammography reported a positive experience. Over 90% reported minimal or no unpleasantness, indicated they would probably undergo CEM in the future if the cost was similar to a traditional mammogram, and that they would very likely recommend it to a friend.

AI-based selection of individuals for supplemental MRI in population-based breast cancer screening: the randomized ScreenTrustMRI trial:
A randomized study conducted by researchers at the Karolinska Institute found that using AI to select women for supplemental MRI screening rather than density alone resulted in 4 times as many cancers detected by MRI (64 vs. 16.5 per 1000). Selecting women based on a high AI score was cost effective, resulting in a cost per cancer detected similar to screening mammography.  This study will ultimately report on the effect of MRI (if any) on reducing advanced breast cancers, including interval cancers.

Amended “Inform” Law, New Study

by

Rhode Island Density Inform Law Amended
In preparation for the FDA’s new dense breast reporting standard going into effect Sept 10, 2024, Rhode Island has amended its existing “inform” law. The Rhode Island inform law will now defer to the FDA’s national reporting standard. Please see DBI’s State Law Map or Table for details.  As previously mentioned, existing state density inform laws may remain in effect in addition to the FDA requirement unless that state law specifically defaults to the new FDA standard, expires, or is repealed.

Just Published
A retrospective study just out in Radiology,  Comparison of Mammography and Mammography with Supplemental Whole-Breast US Tomography for Cancer Detection in Patients with Dense Breasts, evaluated the performance of US tomography (UST)  combined with full-field digital mammography (FFDM) in a reader study in women with dense breasts. The addition of UST improved cancer detection over FFDM alone and the detection rate was comparable to other ultrasound screening methods.
