Seema Khan, MD, on Ductal Carcinoma in Situ: Central MRI and a 12-Gene Expression Assay to Optimize Local Therapy
2023 SABCS
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).

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).

Eleftherios P. Mamounas, MD, of Orlando Health Cancer Institute, discusses primary outcomes from the NRG Oncology/NSABP B-51/RTOG 1304 study of locoregional irradiation in patients with biopsy-proven axillary node involvement at presentation who become pathologically node-negative after neoadjuvant chemotherapy (Abstract GS02-07).

Aditya Bardia, MD, MPH, of Massachusetts General Hospital Cancer Center, discusses phase III findings from the KEYNOTE-756 study, which showed that adding pembrolizumab to chemotherapy increases the pathologic complete response rate and lowers the residual cancer burden in patients with early-stage, high-risk ER-positive or HER2-negative breast cancer (Abstract GS01-02).

Cynthia X. Ma, MD, PhD, of Washington University School of Medicine in St. Louis, discusses phase I findings showing the safety and tolerability of copanlisib and fulvestrant in combination with continuous or intermittent abemaciclib in patients with estrogen receptor–positive, HER2-negative metastatic breast cancer. Preliminary antitumor activity, which was observed, will be further examined in the phase II trial (ClinicalTrials.gov identifier NCT03939897) (Abstract PS17-06).

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).
