Daniel G. Stover, MD, on Early-Stage Breast Cancer: A Biomarker Analysis From the PALLAS Trial
2023 SABCS
Daniel G. Stover, MD, of The Ohio State University Comprehensive Cancer Center, discusses a biomarker analysis from the PALLAS adjuvant trial, which compared 2 years of the CDK4/6 inhibitor palbociclib with endocrine therapy vs endocrine therapy alone, as adjuvant treatment for patients with stage II–III hormone receptor–positive, HER2-negative breast cancer. The genomic subtype PAM50 was defined in the protocol of the PALLAS trial as the primary biomarker for analysis of prediction and prognosis (Abstract GS03-07).

Seema Khan, MD, of Northwestern University and the Robert H. Lurie Comprehensive Cancer Center, discusses the 5-year clinical outcomes of ECOG-ACRIN 4112, a prospective trial that supports the omission of radiotherapy after surgery in patients with ductal carcinoma in situ who have a low DCIS score and its use in patients with intermediate/high DCIS scores (Abstract GS03-01).

Nadia Harbeck, MD, PhD, of LMU University Hospital and Ludwig Maximilian University of Munich, and Daniel Kates-Harbeck, of the West German Study Group and an MD Candidate at Ludwig Maximilian University of Munich, discuss a learning-based neural network developed by Mr. Kates-Harbeck to predict treatment outcomes in early breast cancer as well as potentially other tumor types (Abstract PO 04 1-10).

Peter Schmid, MD, PhD, of Queen Mary University of London and Barts Cancer Institute, discusses phase III findings from KEYNOTE-522 showing that neoadjuvant pembrolizumab plus chemotherapy followed by adjuvant pembrolizumab continues to show a clinically meaningful improvement in event-free survival compared with neoadjuvant chemotherapy alone in patients with early-stage triple-negative breast cancer (TNBC) (Abstract LBO1-01).

Luca Gianni, MD, of Milan’s Fondazione Michelangelo, discusses findings from the APTneo Michelangelo trial, which showed that adding atezolizumab to chemotherapy and trastuzumab plus pertuzumab did not significantly increase the rate of pathologic complete response (pCR) in women with HER2-positive breast cancer. An exploratory analysis showed that adding atezolizumab to neoadjuvant anthracycline and cyclophosphamide followed by HPCT (trastuzumab + pertuzumab and chemotherapy) led to higher pCR rates than HPCT and atezolizumab (Abstract LBO1-02).

Amy Tiersten, MD, of the Icahn School of Medicine at Mount Sinai and Tisch Cancer Institute, discusses findings from the ASPIRE trial, which showed the combination of anastrozole, palbociclib, trastuzumab, and pertuzumab in the front-line setting was well tolerated and effective, with a clinical benefit rate of 97% in patients with previously untreated hormone receptor–positive, HER2-positive metastatic breast cancer (Abstract RF02-01).
