Real-World Feasibility, Toxicity, and Early Outcomes of Neoadjuvant Pembrolizumab-Based Systemic Therapy in Early Triple-Negative Breast Cancer: A Single-Centre Chinese Cohort from Hong Kong
By Lo YG, Chan K and Soong SI.
Abstract
Background
Neoadjuvant treatment for early-stage triple-negative breast cancer has been widely used, and the KEYNOTE-522 (KN522) regimen has become a standard of care for early-stage TNBC, with alternative treatment options including a dose-dense anthracycline/taxane-based regimen for patients without access to neoadjuvant immunotherapy. Nevertheless, real-world evidence in Chinese populations, especially high-risk cohorts such as older populations and those with substantial nodal burden, is limited regarding both efficacy and tolerability. This study describes the outcomes associated with neoadjuvant systemic therapy in a Hong Kong Chinese cohort.
Objectives
This study aimed to describe the feasibility, treatment delivery, tolerability and safety of the KN522 regimen in stage I-III TNBC in a Chinese cohort in Hong Kong. Another cohort treated with dose-dense neoadjuvant chemotherapy, which is also a standard-of-care treatment alternative, is presented to provide context of local treatment practice.
