Breast Cancer

Yael Simons, MD, discusses the racial disparities seen in African Americans patients with luminal breast cancer.

Judy Garber, MD, MPH, discusses the efficacy of adjuvant olaparib in patients with high-risk, HER2-negative breast cancer, as demonstrated in the phase 3 OlympiA trial.

Dr. Masten reflects on the main challenges that arose during the COVID-19 lockdown with regard to surgery in patients with breast cancer, the steps that were taken as the lockdown started to lift, and the changes that have been made with regard to managing patients around the time of surgery and in the operating room.

Douglas W. Blayney, MD, presents data from the 2021 American Society of Clinical Oncology Annual Meeting on the final results from the phase 3 PROTECTIVE-2 trial of Plinabulin and Pegfilgrastim in breast cancer patients treated with high febrile neutropenia risk chemotherapy.

Julia Blanter, MD, discusses the risk of developing distant metastases after initial breast cancer diagnosis among Black vs White women.

Kent Hoskins, MD, discusses the impact of race on breast cancer outcomes.

Rates of clinical trial initiation, novel drug development, and collaborative research and development deals were oncology.

The expansion of HER2-directed treatments and formulations, the availability of CDK4/6 inhibitors, and the broad activity of sacituzumab govitecan-hziy is a testament to the successful development of personalized medicine in breast cancer.

Fam-trastuzumab deruxtecan-nxki is under investigation with or without pertuzumab vs a standard-of-care regimen comprised of a taxane, trastuzumab, and pertuzumab in the frontline treatment of patients with HER2-positive metastatic breast cancer as part of the phase 3 DESTINY-Breast09 trial.

Aditya Bardia, MD, MPH, discusses ongoing research with amcenestrant and palbociclib in estrogen receptor–positive, HER2-negative advanced breast cancer.

Sarat Chandarlapaty, MD, PhD, highlights responses to amcenestrant and palbociclib in patients with estrogen receptor–positive, HER2-negative metastatic breast cancer, as seen in the phase 1/2 AMEERA 1 trial.

Although circulating tumor cell analysis of patients with HER2-negative metastatic breast cancer identified patients with CTC amplification, the utility of subsequent HER2-directed treatment with trastuzumab plus vinorelbine in this patient population was low.

The antibody-drug conjugate vic-trastuzumab duocarmazine was found to significantly improve progression-free survival over physician’s choice of treatment in patients with pretreated HER2-positive unresectable locally advanced or metastatic breast cancer, meeting the primary end point of the phase 3 TULIP trial.

Dr Gradishar and colleagues highlight key clinical trials such as DESTINY-Breast01, HER2CLIMB, NALA, and SOPHIA in the setting of advanced HER2-positive breast cancer and discuss the practical considerations of these data.

Dr Gradishar and colleagues take an in-depth look at data from select clinical trials in the neoadjuvant and adjuvant settings for patients with HER2-positive breast cancer.

In the first segment, Dr Gradishar and colleagues examine the unmet needs clinicians face despite recent advances in the treatment of patients with HER2-positive breast cancer.

Jennifer Litton, MD, highlights responses to talazoparib seen in patients with BRCA1/2-positive, early triple-negative breast cancer.

The antibody-drug conjugate sacituzumab govitecan retained benefit in progression-free survival, overall survival, and objective response rate over physician’s choice of therapy, regardless of the chemotherapy agent used.

Treatment with intra-tumoral SD-101 in combination with pembrolizumab and paclitaxel resulted in a non-statistically significant increase in estimated pathological complete response rates in patients with high-risk, HER2-negative stage II/III breast cancer across 3 HER2-negative biomarker signature groups.

OncLive sits down with Erika P. Hamilton, MD, and Milind Javle, MD, on the pivotal studies in breast cancer and gastrointestinal cancers, respectively, at the 2021 ASCO Annual Meeting.

Patients with early-stage breast cancer who have ultralow risk disease indicated by a 70-gene signature demonstrated have an excellent survival prognosis regardless of clinical risk.

The combination of pyrotinib plus trastuzumab, docetaxel, and carboplatin (TCbH) significantly improved the total pathological complete response rate over TCbH alone in the neoadjuvant treatment of patients with HER2-positive breast cancer.

Pertuzumab plus trastuzumab, and nab-paclitaxel used as neoadjuvant therapy in patients with HER2-positive locally advanced breast cancer induced a pathologic complete response similar to that achieved with docetaxel, carboplatin, trastuzumab, and pertuzumab, with less treatment-related toxicities.

A de-escalated course of neoadjuvant therapy of trastuzumab and pertuzumab with or without added weekly paclitaxel for only 12 weeks yielded high response rates and significant survival in patients with HER2-positive, hormone receptor–negative early breast cancer.

The addition of durvalumab to neoadjuvant anthracycline and taxane–based chemotherapy was found to significantly improve survival in patients with early triple-negative breast cancer.
