A pooled exploratory analysis of phase 3 trials found statistically significant progression-free survival and overall survival benefits with ribociclib/endocrine therapy for patients with hormone receptor–positive, HER2-negative breast cancer and visceral metastases.

Treatment with fam-trastuzumab deruxtecan-nxki yielded promising patient-reported outcomes in patients with hormone receptor–positive, HER2-low metastatic breast cancer, according to Naoto Ueno, MD, PhD.

Findings from the DESTINY-Breast04 trial indicated that patients with hormone receptor–positive, HER2-low metastatic breast cancer experienced promising quality of life following treatment with fam-trastuzumab deruxtecan-nxki.

The phase 2 AMEERA-3 trial revealed no progression-free survival benefit of amcenestrant vs physician’s choice of endocrine monotherapy in patients with endocrine-resistant, estrogen receptor–positive, HER2-negative advanced breast cancer.

Progression-free survival and response results presented from the phase 3 TROPiCS-02 trial at 2022 ESMO indicated sacituzumab govitecan-hziy may be favorable vs physician’s choice of treatment for HER2-low or HER2 IHC0, hormone receptor¬–positive metastatic breast cancer.

The nonsteroidal selective estrogen receptor modulator lasofoxifene resulted in better clinical benefit vs fulvestrant in patients with estrogen receptor (ER)–positive, HER2-negative, ESR1-mutant metastatic breast cancer.

The addition of abemaciclib vs standard-of-care chemotherapy to trastuzumab numerically improved overall survival in women with hormone receptor–positive, HER2-positive advanced breast cancer.

The CDK4/6 inhibitor dalpiciclib in combination with letrozole or anastrozole improved progression free survival in patients with treatment-naïve advanced breast cancer.

Abemaciclib prolonged overall survival when added to a nonsteroidal aromatase inhibitor in hormone receptor–positive, HER2–negative breast cancer, according to updated findings from the MONARCH 3 trial presented at 2022 ESMO.

Updated results from the phase 3 TROPiCS-02 study demonstrated that the novel therapy improved overall survival, objective response rate, duration of response and overall quality of life compared with treatment of physician’s choice.

Angela DeMichele, MD, MSCE, discussed the results of the phase 2 I-SPY2 trial in patients with early breast cancer

Angela DeMichele, MD, MSCE, discussed how the phase 2 I-SPY2 trial in patients with early breast cancer is informing patient therapy decisions in difficult-to-treat situations.

A promising 5-year locoregional recurrence rate highlighted that it is likely safety to de-escalate treatment with locoregional radiotherapy in a population of patients with cT1 to cT2, node-positive breast cancer that has been treated using primary chemotherapy and surgery.

Investigators stated that comprehending the quality of life reduction associated with MRI with or without mammography for patients with ductal carcinoma in situ may help to improve patient experience and help in the development of targeted strategies.

Shared insight on how circulating tumor DNA may be used in real-world clinical practice to improve the value of cancer care.

Angela DeMichele, MD, MSCE, spoke about the I-SPY2 trial, which evaluates patients with early breast cancer who are treated with experimental neoadjuvant systemic therapy regimens.

Focusing broadly on breast cancer, expert oncologists detail how ctDNA may impact patient monitoring and treatment decisions moving forward.

Moving on to the second patient scenario, panelists elucidate the value of ctDNA in patients with triple-negative breast cancer.

Results from the second interim analysis of the phase 3 TROPiCS-02 trial showed significantly improved overall survival among patients with hormone receptor–positive, HER2-negative metastatic breast cancer who were given sacituzumab govitecan vs physician’s choice of treatment.

Valentina Boni, MD, PhD, spoke about numerous trials in the breast cancer space presented at 2022 ASCO.

In the context of clinical trial data and personal experience, experts weigh the value of circulating tumor DNA as a tool in cancer care.

Experts share their perspective on clinical trial data driving the use of circulating tumor DNA in various settings of cancer care.

The European Commission approved olaparib as monotherapy or in combination with endocrine therapy for patients with germline BRCA1/2-mutant, HER2-negative high-risk early breast cancer.

Focusing on breast cancer, lung cancer, and GI cancers respectively, expert oncologists review the utility of circulating tumor DNA assays.

Expert panelists elucidate the mechanisms of ctDNA and MRD testing, providing a broad perspective on how they are used in cancer care.

Treatment with adjuvant radiotherapy in the prone position lowered the odds of desquamation in patients with breast cancer and large breast size.

Mark Pegram, MD, spoke the most important data from the IDEAL trial he believes his colleagues should take away.
