SABCS Expert Commentary | Professor Jin Feng: Reanalysis of the Landmark NSABP B-20 Trial—Can MMAI Become a Low-Cost Option for Risk Stratification?

2026.01.13
At the 2025 San Antonio Breast Cancer Symposium (SABCS 2025), a reanalysis of the landmark NSABP B-20 trial (Abstract No. RF3-03) was presented, exploring the prognostic value and chemotherapy benefit–predictive potential of a multimodal artificial intelligence (MMAI) model based on digital pathology and clinical data in hormone receptor–positive (HR+), node-negative early breast cancer.

At the 2025 San Antonio Breast Cancer Symposium (SABCS 2025), a study titled “Gene Expression-based Subtyping of Early Triple-Negative Breast Cancer for Prediction of Response to Neoadjuvant Immune-chemotherapy in the NSABP B-59/GBG-96-GeparDouze Trial” (Abstract No. RF3-02) was presented. The study provides an in-depth analysis of the heterogeneity of benefit from immunotherapy in early triple-negative breast cancer (TNBC), revealing the predictive value of tumor-infiltrating lymphocytes (TILs) and molecular TNBC subtypes for treatment efficacy.

SABCS Expert Commentary | Professor Wang Xin: ctDNA Clearance Predicts pCR in HER2-Positive Breast Cancer and Supports Precision De-escalation Strategies

2026.01.13
De-escalation therapy has become an important trend in the management of HER2-positive early breast cancer, yet accurately identifying patients who can safely omit chemotherapy remains a major challenge. At the 2025 San Antonio Breast Cancer Symposium (SABCS), the PHERGuide substudy innovatively incorporated circulating tumor DNA (ctDNA) monitoring into the neoadjuvant treatment framework. The study demonstrated that ctDNA clearance is strongly associated with pathological complete response (pCR), while baseline ctDNA positivity predicts poorer outcomes.
