The addition of the checkpoint inhibitor atezolizumab to chemotherapy with carboplatin and nab-paclitaxel failed to significantly improve pathologic complete response rates compared with chemotherapy alone in patients with early high-risk, locally advanced triple-negative breast cancer. According...

This week, the U.S. Food and Drug Administration (FDA) granted Priority Review to agents in lymphoma, lung cancer, gastrointestinal stromal tumors, and breast cancer, and granted Fast Track designation to a first-in-class radioenhancer hafnium oxide nanoparticle in head and neck cancer. Priority...
Ivana Sestak, PhD, of Queen Mary University of London and the Centre for Cancer Prevention, discusses study findings that confirm the prognostic ability of the Clinical Treatment Score at 5 years (CTS5) for late distant recurrence, specifically for patients older than 50 years and/or for those deemed to have intermediate- or high-risk hormone receptor–positive, HER2-negative, node-negative breast cancer. The CTS5 is less prognostic in women younger than 50 who received 5 years of endocrine therapy alone (Abstract GS4-03).
Hongchao Pan, PhD, of the University of Oxford, discusses an analysis of 86,000 women in the Early Breast Cancer Trialists’ Collaborative Group database, which showed that the risk of distant recurrence 20 years after a diagnosis of node-negative, estrogen receptor–negative early-stage breast cancer in women who discontinued endocrine therapy at 5 years is likely to be about a third lower now than in his group’s previous report (Abstract GS2-04).
As reported in the Journal of Clinical Oncology by Rowan T.

Residual cancer burden after neoadjuvant chemotherapy can accurately predict disease recurrence and survival across all breast cancer subtypes, according to the findings from a meta-analysis presented at the 2019 San Antonio Breast Cancer Symposium by W. Fraser Symmans, MD, Professor and Director...
“In the 10-year analysis of the NSABP B-42 trial, the effect of extended treatment with 5 years of letrozole on disease-free survival persisted and reached statistical significance. There was no significant improvement in overall survival with letrozole, but letrozole continued to provide a...
Proton pump inhibitors, which are sometimes recommended to ease stomach problems during cancer treatment, may have an unintended side effect: impairment of breast cancer survivors' memory and concentration. These findings were published by Madison et al in the Journal of Cancer Survivorship....

Neoadjuvant systemic therapy can shrink tumors in patients with breast cancer and, in some cases, allow patients to receive breast-conserving therapy who would otherwise require mastectomy. However, in the United States, about 55% of patients who become eligible for breast-conserving therapy after...
A new study shows that a test physicians commonly use to guide chemotherapy for patients with breast cancer after surgery may also help them decide whether radiation therapy may be of benefit. Results published by Wendy A. Woodward, MD, PhD, and colleagues in JAMA Oncology suggest patients with an...
Lack of insurance coverage is a major cause of delayed breast cancer screening and treatment among minority women, which could lead to a decrease in a patient’s chance of survival. Nearly half of the disparity in later-stage diagnosis between non-Hispanic white women and black, Hispanic, and...
Hope S. Rugo, MD, of the University of California San Francisco Comprehensive Cancer Center, discusses a retrospective analysis on the effectiveness of the VENTANA PD-L1 SP142 assay, the Dako 22C3 assay, and the VENTANA SP263 assay as predictors of response to atezolizumab plus nab-paclitaxel in patients with metastatic triple-negative breast cancer (Abstract PD1-07).
