Molecular testing and genomic testing are now considered standard of care in breast cancer, guiding treatment decisions in early breast cancer and targeted therapies in the metastatic setting. “But tumors evolve,” Virginia Kaklamani, MD, DSc, reminded participants at the 2022 Lynn Sage Breast...
Ruth O’Regan, MD, of the University of Rochester Medical Center, discusses the Breast Cancer Index (BCI), a genomic assay that can assess the risk of late distant recurrence (5–10 years after diagnosis) of hormone receptor–positive, early-stage breast cancer. Among premenopausal women with this disease who were enrolled in the SOFT trial, those with a high BCI score had an increased risk of distant recurrence. Those with a low BCI score benefited more from the addition of ovarian suppression therapy to endocrine therapy after 12 years of follow-up (Abstract GS1-06).
Yara Abdou, MD, of the University of North Carolina, discusses results from the RxPONDER SWOG S1007 study, which showed that non-Hispanic Black women with hormone receptor–positive/HER2-negative breast cancer with one to three involved lymph nodes and a recurrence score of ≤ 25 have worse outcomes than non-Hispanic White women. In addition, Black patients were more likely to accept treatment assignment than their White counterparts and were just as likely to remain on estrogen therapy at 6 and 12 months, suggesting that outcome differences may be less likely attributable to lack of treatment compliance within the first year (Abstract GS1-01 ).
A silicone-based polyurethane film dressing (known as Mepitel® Film) appears to be beneficial in reducing skin toxicities caused by radiation treatment, according to data presented during the October 2022 ASCO Plenary Series.1 The results of a phase III trial showed that this film dressing may be...
Compared with capecitabine-based regimens, fam-trastuzumab deruxtecan-nxki (T-DXd) led to higher response rates and longer survival in the third-line setting for patients with HER2-positive metastatic breast cancer previously treated with ado-trastuzumab emtansine (T-DM1), according to results from ...
Patients with localized, hormone receptor (HR)-positive, HER2-low breast cancer treated with fam-trastuzumab deruxtecan-nxki (T-DXd) in the neoadjuvant setting had an overall response rate of 75% without combining the agent with anastrozole and 63% in combination with anastrozole, according to...
In patients with hormone receptor–positive, HER2-negative advanced breast cancer—including patients with visceral crises—those treated with ribociclib plus endocrine therapy had fewer adverse events and significantly longer progression-free survival compared to those treated with combination...
The incidence of anaplastic large cell lymphoma (ALCL) has surged in recent years—possibly because of the growing use of textured breast implants. Considering this trend, some patients with breast cancer who undergo mastectomy may wonder if the benefits of getting reconstructive implants are worth...
Residual tumors from Black patients with estrogen receptor–positive/HER2-negative primary breast cancer treated with neoadjuvant chemotherapy had a higher risk score associated with a biomarker of distant metastatic recurrence compared with tumors from White patients, according to new findings...
Among premenopausal patients with hormone receptor–positive, early-stage breast cancer enrolled in the SOFT trial, those with a high score on the Breast Cancer Index genomic assay had an increased risk of distant recurrence—and those with a low score on the Breast Cancer Index may have benefited...

In a U.S. cross-sectional study reported in JAMA Oncology, Oakes et al found that as of December 2021, breast, cervical, and colorectal cancer screening rates remained below pre–COVID-19 pandemic levels, despite initial rebounds in some rates. Reduced screening rates were accompanied by reduced...
Twenty percent of patients are likely to forgo additional testing after an abnormal finding on a screening mammogram if there is a deductible, according to new findings presented at the Radiological Society of North America (RSNA) 2022 Annual Meeting. Background As health-care costs and insurance...
Patients with HER2-positive breast cancer may be less likely to survive if their initial treatment fails to eradicate the tumor completely and they have high levels of tumor-infiltrating lymphocytes in their residual tumors, according to a new study published by Miglietta et al in the European...
Using intraoperative ultrasound to guide surgery for patients with ductal carcinoma in situ may yield better results than the standard technique of using a wire inserted into the breast, according to a new study published by Esgueva et al in the European Journal of Cancer. The findings were also...

Survival outcomes with the ...
Do patients with breast cancer and a low 21-gene recurrence score need regional node irradiation to reduce their risk of locoregional recurrence? An analysis of RxPONDER trial data suggests only a randomized clinical trial devoted to this question can provide a decisive answer. An analysis of data...

It has been well documented that breast cancer is the most common malignancy in adolescent and young adult (AYA) women aged 15 to 39 years, accounting for 30% of cancers among this population.1 In addition, 5.6% of all invasive breast cancers occur in AYA women.1 A presentation by Rebecca H....
A multicenter analysis of patients with invasive lobular carcinoma—the second most common histologic subtype of invasive breast cancer in the United States—showed that, despite its prevalence, invasive lobular carcinoma was detected later with worse outcomes vs invasive ductal carcinoma and had...
Studies show that rural populations experience greater cancer disparities across the cancer control continuum—from prevention and incidence to survivorship and mortality—compared with their urban counterparts. Those living in rural parts of the United States also tend to have lower cancer screening ...
