Breast Cancer

Adjuvant ado-trastuzumab emtansine continued to improve overall survival and invasive disease-free survival vs trastuzumab after 8.4 years of follow-up in patients with HER2-positive early breast cancer and residual invasive disease following neoadjuvant therapy enrolled in the phase 3 KATHERINE trial.

The brain-penetrant oral selective estrogen receptor degrader SIM0270 exhibited a favorable safety profile and early signals of antitumor activity in patients with estrogen receptor-positive, HER2-negative locally advanced or metastatic breast cancer, including those with ESR1 mutations.

A continued statistically significant improvement in iDFS was observed for patients with HR-positive, HER2-negative early-stage breast cancer who received ribociclib plus a nonsteroidal AI vs a nonsteroidal AI alone, according to the final iDFS analysis of the phase 3 NATALEE trial.

Treatment with elacestrant led to a clinically meaningful improvement in progression-free-survival compared with standard-of-care therapy among patients with estrogen receptor–positive/HER2-negative, ESR1-mutated advanced or metastatic breast cancer.

Anastrozole or fulvestrant plus fam-trastuzumab deruxtecan-nxki demonstrated encouraging antitumor activity in patients with chemotherapy-naïve, HER2-low hormone receptor–positive metastatic breast cancer.

Treatment with trastuzumab deruxtecan generated clinical responses in patients with HER2-low or HER2-positive advanced breast cancer with pathologically confirmed leptomeningeal carcinomatosis.

Datopotamab deruxtecan resulted in a statistically significant and clinically meaningful improvement in progression-free survival compared with chemotherapy among patients with previously treated, hormone receptor-positive/HER2-negative inoperable or metastatic breast cancer.

The addition of inavolisib to palbociclib and fulvestrant improved progression-free survival vs palbociclib and fulvestrant alone in select patients with PIK3CA-mutated, hormone receptor–positive, HER2-negative, locally advanced or metastatic breast cancer.

Precise stratification of hormone receptor–positive, HER2-negative breast cancer using BluePrint and MammaPrint assays revealed comparable 3-year recurrence-free survival rates between Black and White patients despite observed racial differences in the distribution of molecular subtypes.

Pembrolizumab plus olaparib did not improve progression-free or overall survival vs pembrolizumab plus chemotherapy in patients with locally recurrent inoperable or metastatic triple-negative breast cancer who received induction pembrolizumab plus chemotherapy.

The addition of pembrolizumab to neoadjuvant chemotherapy followed by adjuvant pembrolizumab plus endocrine therapy improved pathologic complete responses in key subsets of patients with early-stage, high-risk, estrogen receptor–positive/HER2-negative breast cancer enrolled in the phase 3 KEYNOTE-756 trial.

Capivasertib plus fulvestrant did not negatively affect quality of life compared with placebo plus fulvestrant in patients with aromatase inhibitor–resistant, hormone receptor–positive, HER2-negative advanced breast cancer.

Utilizing an artificial intelligence–assisted workflow to detect sentinel lymph node metastases in patients with breast cancer was deemed safe according to current diagnostic standards and reduced the need for immunohistochemistry and its associated financial burden.

The combination of ribociclib and endocrine therapy led to an improvement in progression-free survival and overall survival vs placebo plus endocrine therapy in patients with hormone receptor-positive/HER2-negative advanced breast cancer across all age groups.

The expert panel concludes the program with key takeaways and closing thoughts on the evolving antibody-drug conjugate space.

Joseph A. Sparano, MD, FACP, discusses developments in breast cancer diagnosis and treatment.

The FDA has granted fast track designation to zotatifin for use in combination with fulvestrant and abemaciclib as second- or third-line therapy for the treatment of patients with estrogen receptor-positive, HER2-negative advanced or metastatic breast cancer with disease progression following treatment with endocrine therapy and a CDK4/6 inhibitor.

With multiple antibody drug conjugate options now available for patients with HER2-negative metastatic breast cancer, clinicians must consider a variety of factors when selecting and sequencing therapies.
