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).

Sherene Loi, MD, PhD, of Australia’s Peter McCallum Cancer Centre, discusses an exploratory analysis of CheckMate 7FL which showed that patients with PD-L1–positive, high-risk, estrogen receptor–positive, HER2-negative primary breast cancer may achieve substantial pathologic complete response rates with the addition of nivolumab to neoadjuvant chemotherapy (Abstract GS01-01).

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).

Barbara Pistilli, MD, of France’s Gustave Roussy, discusses a phase Ib analysis from the CAPItello-292 study, which showed capivasertib plus palbociclib plus fulvestrant was tolerable at all dose levels in heavily pretreated patients with hormone receptor–positive, HER2-negative advanced breast cancer. As data collection continues, evidence of clinical activity has been observed in patients treated with the recommended phase III dose (Abstract PS12-09).

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).

Sara A. Hurvitz, MD, of Fred Hutchinson Cancer Research Center, University of Washington, discusses phase III findings of the HER2CLIMB-02 study, which showed the combination of tucatinib and trastuzumab emtansine improved progression-free survival in patients with previously treated, HER2-positive, locally advanced or metastatic breast cancer (including those with brain metastases) (Abstract GS01-10).
