Ciara C. O’Sullivan, MD, MBBCh, on HER2-Positive Breast Cancer: Expert Commentary on Treatments Under Study
2024 ASCO Annual Meeting
Ciara C. O’Sullivan, MD, MBBCh, of Mayo Clinic, discusses three studies of treatment for patients with HER2-positive metastatic breast cancer and their clinical implications: the EMERALD trial of eribulin and taxane; the Patricia Cohort C trial of palbociclib plus trastuzumab and endocrine therapy; and DB07 on trastuzumab deruxtecan with or without palbociclib.

Andrea Cercek, MD, of Memorial Sloan Kettering Cancer Center, discusses expanded data on the durability of complete response to dostarlimab-gxly, a PD-1 single-agent therapy administered to patients with locally advanced mismatch repair–deficient rectal cancer. The drug yielded recurrence-free responses, lasting longer than a year, without the need for chemotherapy, radiation, or surgery (LBA3512).

Reshma Jagsi, MD, DPhil, of Emory University Winship Cancer Institute, and Christian F. Singer, MD, MPH, of the Medical University of Vienna, discuss the MUC-1 vaccine tecemotide. When added to standard neoadjuvant systemic therapy for patients with early-stage breast cancer, this vaccine improved distant relapse–free and overall survival rates. Despite the exploratory nature of this observation, says Dr. Singer, this is the first long-term survival benefit of an anticancer vaccine in breast disease reported to date (Abstract 587).

Heather Wakelee, MD, of Stanford University Medical Center, discusses phase III findings showing that the disease-free survival benefit with adjuvant atezolizumab continues to translate into a positive overall survival trend vs best supportive care in patients with stage II–IIIA non–small cell lung cancer (NSCLC). These results further support the use of adjuvant atezolizumab in PD-L1–selected populations, according to Dr. Wakelee (LBA8035).

Tony S.K. Mok, MD, of The Chinese University of Hong Kong, discusses phase III findings from the KRYSTAL-12 study, which showed that adagrasib improved progression-free survival and overall response rate over docetaxel in patients with locally advanced or metastatic non–small cell lung cancer harboring a KRAS G12C mutation who had previously received a platinum-based chemotherapy with anti–PD-(L)1 treatment.

Lisa A. Carey, MD, of University of North Carolina, Chapel Hill and UNC Lineberger Comprehensive Cancer Center, and Kevin Kalinsky, MD, of the Winship Cancer Institute of Emory University, discuss the first phase III findings showing a benefit of continued CDK4/6 inhibition with abemaciclib plus fulvestrant, following disease progression in patients with hormone receptor–positive, HER2-negative advanced breast cancer (LBA1001).
