In recent years, the antibody-drug conjugates (ADCs) have become one of the significant treatment drugs for patients with human epidermal growth factor receptor 2 (HER2)-positive. ADCs provides new treatment options, and it improves outcomes and quality of life for patients with HER2-positive advanced breast cancer. However, we need to pay special attention to the adverse events (AEs) caused by ADCs, such as gastrointestinal reactions, bone marrow suppression, and interstitial lung disease (ILD), etc. At present, clinicians are in the initial stage of understanding the AEs caused by ADCs, and there is no expert consensus for the treatment on the AEs caused by ADC.

Until recently, the majority of the studies in BC focused on evaluating a single liquid biopsy analyte, primarily circulating tumor DNA and circulating tumor cells (CTCs). Despite the proven prognostic and predictive value of CTCs, their low abundance when detected using enrichment methods, especially in the early stages, poses a significant challenge. It is becoming evident that combining diverse circulating biomarkers, each representing different facets of tumor biology, has the potential to enhance the management of patients with BC. This article emphasizes the importance of considering these biomarkers as complementary/synergistic rather than competitive, recognizing their ability to contribute to a comprehensive disease profile. The review provides an overview of the clinical significance of simultaneously analyzing CTCs and other biomarkers, including cell-free circulating DNA, extracellular vesicles, non-canonical CTCs, cell-free RNAs, and non-malignant cells. Such a comprehensive liquid biopsy approach holds promise not only in BC but also in other cancer types, offering opportunities for early detection, prognostication, and therapy monitoring. However, addressing associated challenges, such as refining detection methods and establishing standardized protocols, is crucial for realizing the full potential of liquid biopsy in transforming our understanding and approach to BC.
