Spotlight on SABCS, insights delivered live. The 48th San Antonio Breast Cancer Symposium (SABCS) was held from December 9 to 12, 2025, in San Antonio, USA, bringing together cutting-edge research findings and clinical insights from across the global breast cancer community. To efficiently convey the highlights of the meeting, this edition of Insight Broadcast invited Professor Junjie Li from Fudan University Shanghai Cancer Center as an on-site expert commentator. Focusing on neoadjuvant therapy for HER2-positive breast cancer, Professor Li provides an in-depth interpretation of the latest research advances on the use of biomarkers such as tumor-infiltrating lymphocytes (TILs) and circulating tumor DNA (ctDNA) to enable more precise patient selection and response prediction, while critically examining their potential, limitations, and future directions from a clinical perspective.

Spotlight on SABCS, insights delivered in real time. The 48th San Antonio Breast Cancer Symposium (SABCS) was held from December 9 to 12, 2025, in San Antonio, USA, bringing together cutting-edge research findings and clinical insights from the global breast cancer community. To efficiently convey the key messages of the meeting, this edition of Insight Broadcast invited Professor Jin Yang from the First Affiliated Hospital of Xi’an Jiaotong University as the on-site expert commentator. Drawing on two pivotal studies—ASCENT-07 and lidERA—Professor Yang interprets the latest advances and challenges in first-line treatment of advanced disease and adjuvant therapy in early-stage HR+/HER2− breast cancer, while exploring the evolving treatment paradigm and future directions.

At the 2025 San Antonio Breast Cancer Symposium (SABCS 2025), results were presented from a study titled “HER2CLIMB-05: A Randomized, Double-Blind Phase III Study of Tucatinib versus Placebo in Combination with Trastuzumab and Pertuzumab as Maintenance Therapy for HER2-Positive Metastatic Breast Cancer” (Abstract No. GS1-01). This study explored an intensified strategy for first-line maintenance therapy in patients with HER2-positive metastatic breast cancer (HER2+ MBC). Oncology Frontier invited Professor Xiaoyun Mao from The First Hospital of China Medical University to provide a detailed overview and expert commentary on the study, with the aim of optimizing clinical decision-making.

Recently, the 17th Shanghai Breast Cancer Professional Symposium, held in conjunction with the Annual Meeting of the Breast Cancer Committee of the Shanghai Anti-Cancer Association and the 2026 Breast Cancer Guideline “Red Book” Update Meeting, took place in Shanghai. During the meeting, the 2026 Edition of the Essentials of the Breast Cancer Diagnosis and Treatment Guidelines and Specifications—jointly issued by the Chinese Anti-Cancer Association Breast Cancer Committee (CBCS) and the Breast Oncology Group of the Chinese Society of Clinical Oncology (CSOBO)—was officially released (hereinafter referred to as the new Red Book).

From “following evidence” to “creating evidence”, clinical research in breast cancer in China is entering a deep phase of high-quality development. Within the grand framework of precision medicine, industry-sponsored trials (ISTs) may serve as the gateway for innovative drugs to enter clinical practice, but investigator-initiated trials (IITs) are the master key to solving the “last mile” problems of real-world clinical application.

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 based on data from the NSABP B-42 and TAILORx trials (Abstract No. RF3-07) reported the development and validation of a multimodal, multitask deep learning model (Clarity BCR). By integrating routine digital pathology images with key clinical variables, this model accurately predicts the risk of late distant recurrence (late DR) in patients with hormone receptor–positive (HR+) early breast cancer and effectively identifies those who may benefit from extended endocrine therapy (EET).

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.
