Investigators have found that race and ethnicity may affect the 21-gene recurrence score in patients with early-stage, estrogen receptor–positive breast cancer, according to new findings presented by Gill et al at the 2023 ASCO Annual Meeting (Abstract 511). Background The 21-gene recurrence...
Lisa A. Carey, MD, of the University of North Carolina at Chapel Hill, and Javier Cortes, MD, PhD, of the International Breast Cancer Center and Universidad Europea de Madrid, discuss phase II findings showing that one in three patients with HER2-positive early breast cancer may safely omit chemotherapy. Among the chemotherapy-free patients treated with trastuzumab and pertuzumab, the 3-year invasive disease–free survival was 98.8%, with no distant metastases (Abstract LBA506).
Lisa A. Carey, MD, of the University of North Carolina at Chapel Hill, and Dennis J. Slamon, MD, PhD, of the University of California, Los Angeles, discuss phase III study findings on ribociclib plus endocrine therapy as adjuvant treatment in patients with hormone receptor–positive, HER2-negative early breast cancer. When added to standard-of-care endocrine therapy, ribociclib improved invasive disease–free survival with a well-tolerated safety profile (Abstract LBA500).
Jennifer A. Ligibel, MD, of Dana-Farber Cancer Institute, discusses a telephone-based weight loss intervention that induced clinically meaningful weight loss in patients with breast cancer who had overweight and obesity, across demographic and tumor factors. Additional tailoring of the intervention may possibly enhance weight loss in Black and younger patients as well (Abstract 12001).
Adding the CDK4/6 inhibitor ribociclib to endocrine therapy resulted in a significant improvement in invasive disease–free survival for patients with hormone receptor–positive, HER2-negative early-stage breast cancer. Findings from the phase III NATALEE trial were presented by Dennis J. Slamon, MD, ...
Early-phase data from the SOLTI TOT-HER3 and ICARUS-BREAST01 trials suggest that the novel HER3-directed antibody-drug conjugate patritumab deruxtecan may have beneficial activity in patients with hormone receptor–positive/HER2-negative and triple-negative breast cancer subtypes, according to...
Delays in cancer screenings during the COVID-19 pandemic may have resulted in lower reported incidences of colorectal, lung, and breast cancers, reflecting potentially high rates of undiagnosed cancer and later-stage diagnoses, according to a new study published by Romatoski et al in the Journal of ...
In an interim analysis of a Chinese phase III trial (DAWNA-2) reported in The Lancet Oncology, Zhang et al found that the addition of the CDK4/6 inhibitor dalpiciclib to letrozole or anastrozole improved progression-free survival as first-line treatment in patients with advanced hormone...

Updated recommendations from the American College of Radiology encouraged all women—particularly Black women and Ashkenazi Jewish women—to undergo risk assessments at 25 years of age to determine whether they may need breast cancer screenings earlier than age 40, according to new guidelines...
In hormone receptor–positive metastatic breast cancer, tumors eventually become resistant not only to endocrine blockade but to inhibitors of cyclin-dependent kinases 4 and 6 (CDK4/6). This obstacle to successful treatment is being tackled with novel hormone receptor–directed therapies, with the...
On May 9, the U.S. Preventive Services Task Force (USPSTF) posted a draft recommendation statement on screening for breast cancer. The USPSTF now recommends that all women get screened for breast cancer every other year starting at age 40 years (this is a B grade recommendation, meaning the USPSTF...
In a Japanese phase III trial (AERAS) reported in the Journal of Clinical Oncology, Iwase et al found that an additional 5 years of adjuvant anastrozole after 5 years of anastrozole or tamoxifen followed by anastrozole was associated with improved disease-free survival vs no further anastrozole...

Anita Mamtani, MD, of Memorial Sloan Kettering Cancer Center, discusses study findings showing that axillary lymph node dissection was required by less than 2% of patients with cT1NO triple-negative or HER2-positive breast cancer having upfront surgery. There was no clear advantage of neoadjuvant chemotherapy in reducing the risk of lymph node dissection in this cohort. Upfront surgery is a suitable approach in these patients, says Dr. Mamtani, allowing for de-escalated chemotherapy regimens in patients with pathologic node-negative disease. (Abstract P1).
Kari M. Rosenkranz, MD, of Dartmouth Health, discusses findings from the ACOSOG Z11102 (Alliance) study, which showed that breast-conserving therapy is safe for patients with multiple ipsilateral breast cancer lesions, resulting in low recurrence rates. However, omitting adjuvant endocrine therapy is a risk factor for recurrence. (Abstract 1).
Judy C. Boughey, MD, of the Mayo Clinic, discusses the decrease, over the past decade, of axillary lymph node dissection, especially in patients with node-positive breast cancer at diagnosis who had sentinel lymph node surgery after neoadjuvant chemotherapy. These findings are based on the records of more than 1,400 patients enrolled in the I-SPY2 trial. (Abstract 3).
In an analysis reported in the Journal of Clinical Oncology, Marion T. van Mackelenbergh, MD, PhD, and colleagues found that patients with early HER2-positive breast cancer who achieved pathologic complete response (pCR) on neoadjuvant chemotherapy plus anti-HER2 treatment had better overall and...

As reported in The Lancet by the Early Breast Cancer Trialists’ Collaborative Group (EBCTCG), a patient-level meta-analysis showed that anthracycline/taxane regimens were associated with better outcomes compared with regimens excluding either drug class in patients with early-stage operable breast...
Lindsay L. Peterson, MD, of the Washington University, St. Louis, discusses the value of physical activity in improving cancer prognosis, especially for patients with breast or colon cancer. Aerobic exercises and resistance training are recommended during and after treatment. Exercise may help inhibit tumor growth, improve quality of life by decreasing fatigue and anxiety, build muscle mass, increase physical function, and reduce surgical complications and treatment delays.
Patients who underwent pathology evaluation of their sentinel lymph nodes during mastectomy surgery may have been significantly more likely to receive aggressive nodal therapy than patients whose lymph node biopsies and treatment strategies were evaluated after surgery. The new findings were...
Two new studies revealed that specialized exercise and wellness programs may significantly increase physical well-being and quality of life as well as reduce health-care costs in patients with breast cancer, according to findings presented by Wonders et al and Brahmbhatt et al at the 24th American...

In a secondary analysis of the phase III SB3-G31-BC trial, Pivot et al found that perioperative use of the trastuzumab biosimilar SB3 was associated with a similar cardiac safety profile and similar efficacy outcomes compared with reference trastuzumab after up to 6 years of follow-up in patients...
Researchers may have discovered a new therapeutic target for patients with breast cancer—the TONSL gene—while attempting to understand the mechanisms behind breast cancer cell pathogenesis, according to a novel study published by Khatpe et al in Cancer Research. “Most of the cancer research to date ...
As reported in The Lancet by André et al, the phase III DESTINY-Breast02 trial has shown improved progression-free survival with fam-trastuzumab deruxtecan-nxki vs physician’s choice of treatment in patients with HER2-positive metastatic breast cancer who had received prior ado-trastuzumab...
Cancer has stalked my family for generations. My mother, brother, and maternal uncle were diagnosed with melanoma. Fortunately, all survived. When my sister was diagnosed with early-stage invasive ductal carcinoma in 2010, she underwent genetic testing, which showed she was positive for the BRCA2...

Sherry X. Yang, MD, PhD, of the National Cancer Institute, discusses findings from the TAILORx trial, which showed that, despite chemotherapy, patients with high recurrence scores continue to have a poor prognosis. This result suggests the need to develop new management strategies for patients with early-stage breast cancer. (Abstract LB119)
Researchers revealed that 39.2% of patients who consented to whole-exome sequencing and were identified as carriers of predisposition genes for hereditary breast and ovarian cancer or Lynch syndrome did not qualify for genetic screening under current guidelines, according to new findings presented...
