Breast Cancer

Despite improvements in access to health coverage under the Affordable Care Act (ACA), racial disparities in breast cancer mortality rates persist and the underuse of advanced breast imaging may be one culprit, experts say.
 

In a recent position statement, researchers highlighted the disproportionally high breast cancer mortality rates among Black women in Louisiana – a state that has one of the highest breast cancer mortality rates in the nation. In 2019, the breast cancer mortality rate among Black women in Louisiana was 29.3 per 100,000 women compared with the national rate of 19.4 per 100,000.

Although Louisiana has made strides in improving access to breast cancer screening in recent years, the use of advanced imaging – specifically breast MRI – remains underused in this high-risk population. A major barrier to wider use of breast MRI has been cost, and ACA expansion led to higher, not lower, out-of-pocket costs for this screening modality.

“Breast MRI is a powerful imaging tool for early detection and for screening women at high risk for breast cancer,” wrote the researchers, led by Brooke L. Morrell, MD, of Louisiana State University Health and Sciences Center, New Orleans.

However, greater access to health care has not necessarily translated to increased breast MRI screening or improved survival among Black women. Even years after the adoption of the ACA, “Black women in Louisiana continue to die of breast cancer at rates significantly greater than the national average,” the authors wrote.

The position statement was published in Cancer.

Breast MRI is known to provide the highest rate of breast cancer detection among commonly used imaging options, with a sensitivity ranging from 81% to 100%. That’s about twice as high as the sensitivity range for mammography after factoring in breast density.

“This is of particular importance when we consider the risk‐based screening of younger populations, in which dense breasts are more prevalent,” the authors explained.

For Black women in particular, studies show nearly a quarter (23%) who develop breast cancer are diagnosed under the age of 50, compared with 16% of White women. Black women are also more likely to develop more aggressive, premenopausal breast cancers, including triple-negative breast cancer, that are more easily detected on MRI.

“Adding supplemental screening breast MRI to annual mammography in higher risk women has been shown to detect up to 18 additional cancers out of 1,000 patients,” Dr. Morrell said. And “many of these cancers are detected much earlier than with mammography alone.”

Still, with ACA expansion, out-of-pocket costs for breast MRI actually increased. This increase likely occurred, in part, because the financial protections outlined in the ACA’s Women’s Preventive Services Guidelines covered mammograms but not breast MRI.

More specifically, under the ACA, Medicaid and most private health insurance plans are required to provide coverage for mammograms at no cost to the patient. The percentage of health plans providing zero cost sharing for mammograms increased under the ACA from 81.9% to 96.8%, but the corresponding rates of zero cost sharing for breast MRI screening went in the opposite direction – from 43.1% in 2009 to only 26.2% in 2017, a 2022 study found.

This study also highlighted geographic variations in zero cost sharing and out-of-pocket costs for screening breast MRI, with a higher financial burden observed for women living in the South. In addition, studies have demonstrated that race and socioeconomic factors, including education and income, play a role in the underuse of screening, including breast MRI.

These factors all likely contribute to screening breast MRI remaining inaccessible to many women, Dr. Morrell and colleagues said.

The authors also outlined three key action items that could help address barriers to MRI breast screening, which include reducing the high cost of breast MRI, lobbying to include breast MRI in ACA protections, and addressing knowledge gaps among patients and clinicians to better identify women who might benefit from breast MRI.

On the financial front, the team explained that a central driver for high costs is the scan time for breast MRI, which could be substantially reduced from 30 to 5 minutes, using an abbreviated protocol.

“Widespread use of low‐cost breast abbreviated MRI screening could remove the cost barrier of adding breast MRI screening to ACA coverage,” without compromising diagnostic accuracy, the authors noted.

Further efforts should focus on overcoming cultural barriers, including fear and mistrust of the health care system among Black women. Outreach efforts could include public campaigns or town hall and church gatherings that enlist patient navigators, advocates, or community members.

“Our visibility in the community builds trust and affords us the opportunity to share knowledge that may empower women to be their own health advocates,” the authors wrote.

In terms of the feasibility of revising ACA policies to improve breast MRI access and affordability, Dr. Morrell pointed to improvements made in colon cancer screening.

“Studies have demonstrated that after ACA policy changes lowering out-of-pocket cost for colonoscopies, screening colonoscopy rates significantly increased among men, predominantly in socioeconomically disadvantaged population,” she noted. “Similarly, we should investigate how to this can be applied to screening breast MRI.”

The elevated risk for recurrence in young women with HR+ early breast cancer highlights the importance of aggressive endocrine therapy in the majority of patients in this population. Examples of approaches to maximize endocrine therapy benefit include the addition of ovarian suppression to either tamoxifen or an aromatase inhibitor (AI) as well as an extended duration of adjuvant endocrine therapy.^4,5 Among 3047 premenopausal women included in SOFT study, at 12 years follow-up, the addition of ovarian function suppression (OFS) to tamoxifen significantly improved disease-free survival (DFS) compared with tamoxifen alone (hazard ratio 0.82; P = .03) with a more pronounced DFS benefit with exemestane plus OFS compared with tamoxifen (hazard ratio 0.69) (Francis et al). In the HER2- subgroup, those who received prior chemotherapy had 12-year OFS rates of 78.8% with tamoxifen, 81.1% with tamoxifen plus OFS and 84.4% with exemestane plus OFS. Furthermore, in the HER2- subgroup, women younger than 35 years had absolute improvements in 12-year OS of 9.1% with tamoxifen plus OFS and 16.5% with exemestane plus OFS compared with tamoxifen. These updated results provide further support for OFS added to tamoxifen or an AI (with more benefit seen with an AI) in the treatment of HR+ early breast cancer in young women who are at high risk for recurrence. Longer follow-up will be important to better define the treatment effect considering recurrence patterns for this subtype of breast cancer.

Various guidelines recommend the use of adjuvant bisphosphonates for postmenopausal patients with early breast cancer on the basis of disease-free and bone metastasis-free survival benefits.⁶ A regimen of zolendronic acid every 6 months for 3 years is commonly used in clinical practice. A substudy of ABCSG-12, including 725 premenopausal patients with HR+ early breast cancer on ovarian suppression randomly assigned to receive tamoxifen or anastrozole with or without zolendronic acid every 6 months, investigated the effect of shorter duration of bisphosphonate therapy on breast cancer outcomes (Beltran-Bless et al). After a median follow-up of 96 months, there was no statistically significant difference in DFS (hazard ratio 0.88; log-rank P = .642) or OS (stratified hazard ratio 1.16; log-rank P = .796) between patients who received ≤6 or ≥7 infusions. Rates of adverse events were increased in the patients who received ≥7 or ≤6 infusions (arthralgia, 20.1% vs 12.4%; nausea, 12.8% vs 7.3%; bone pain, 41.6% vs 34.9%). Modifications to adjuvant breast cancer regimens that can provide more ease for patients with less toxicity while maintaining efficacy are greatly desired to simultaneously support quality of life and disease outcomes.

Key clinical point: The presence of metabolic syndromes (MetS) worsened survival outcomes and increased disease recurrence risk in patients with breast cancer (BC) who received neoadjuvant chemotherapy (NAC).

Major finding: The MetS group had a significantly lower likelihood of achieving pathological complete response than the non-MetS group (odds ratio [OR] 0.316; P  =  .028), with the risk for death (OR 2.587; P  =  .004) and disease recurrence (OR 2.228; P  =  .007) being significantly higher in patients with vs without MetS.

Study details: Findings are from a retrospective study including 221 women with BC who received preoperative NAC, of which 22.2% of patients were included in the MetS group.

Disclosures: This study was supported by the Beijing Medical Award Foundation. The authors declared no conflicts of interest.

Major finding: The MetS group had a significantly lower likelihood of achieving pathological complete response than the non-MetS group (odds ratio [OR] 0.316; P  =  .028), with the risk for death (OR 2.587; P  =  .004) and disease recurrence (OR 2.228; P  =  .007) being significantly higher in patients with vs without MetS.

Study details: Findings are from a retrospective study including 221 women with BC who received preoperative NAC, of which 22.2% of patients were included in the MetS group.

Disclosures: This study was supported by the Beijing Medical Award Foundation. The authors declared no conflicts of interest.

Key clinical point: Recent phase 2 trials have recommended a 2-weekly schedule of pegylated liposomal doxorubicin (PLD) in patients with heavily treated metastatic breast cancer (BC); however, it failed to demonstrate any advantage in terms of efficacy or safety over the registered 4-weekly regimen of PLD.

Major finding: The median progression-free survival was 3.0 and 3.4 months in the 2-weekly and 4-weekly PLD schedule groups, respectively, with a weighted hazard ratio of 1.12 (P  =  .54). The rate of adverse events also appeared comparable between both the groups.

Study details: Findings are from a retrospective study including 191 heavily pretreated patients with metastatic BC who received a 2-weekly (n = 95) or the registered 4-weekly (n = 96) schedule of PLD.

Key clinical point: Autologous fat grafting (AFG) in the second stage of a 2-stage prosthetic breast reconstruction was linked to a higher risk for breast cancer (BC) recurrence when performed within a year after mastectomy.

Major finding: Patients who did vs did not undergo AFG within 1 year after the primary operation had a significantly increased risk for disease recurrence (hazard ratio 5.701; 95% CI 1.164-27.927). However, delaying the fat grafting beyond 12 months after mastectomy did not affect survival outcomes.

Study details: Findings are from a retrospective cohort study including 267 patients with unilateral invasive BC who underwent total mastectomy and immediate tissue-expander-based reconstruction, of which 203 patients underwent the second-stage operation within 12 months of mastectomy and 64 patients underwent the operation after 12 months of mastectomy.

Key clinical point: Addition of atezolizumab to carboplatin+paclitaxel in the neoadjuvant setting improved the pathological complete response (pCR) rate in patients with stage II-III triple-negative breast cancer (TNBC).

Major finding: After a median follow-up of 6.6 months, a significantly higher proportion of patients achieved pCR in the atezolizumab+chemotherapy vs chemotherapy-only group (55.6% vs 18.8%; P  =  .018). However, the increase in the percentage of tumor infiltrating lymphocytes was nominal and not significantly different between both groups (P  =  .36). Grade ≥3 treatment-related adverse events were reported by 62.5% vs 57.8% of patients in the only chemotherapy vs atezolizumab+chemotherapy group, respectively.

Study details: Findings are from the phase 2 NCI-10013 study including 67 patients with previously untreated stage II and III TNBC who were randomly assigned to receive neoadjuvant carboplatin+paclitaxel with or without atezolizumab.
