Compared with parental cells, these resistant cells exhibited reduced sensitivity to paclitaxel, adriamycin, and eribulin in the viability assays. These results suggest that ZSTK3744 combines robust cell growth-inhibitory activity with a favorable safety profile. In conclusion, ZSTK3744 is a promising candidate for overcoming chemotherapy resistance in TNBC, addressing the urgent need for more effective treatment options for this aggressive cancer subtype.

HER-2 (Human epidermal growth factor receptor 2) • CYP1A1 (Cytochrome P450 Family 1 Subfamily A Member 1) • CYP1B1 (Cytochrome P450 Family 1 Subfamily B Member 1) • TIPARP (TCDD Inducible Poly(ADP-Ribose) Polymerase)
An ALC ≥ 1000/μL at ERI completion was associated with an improved post-ERI OS (OS2). It is suggested that not only the factors at the initiation of ERI, but also the immunological status at the end of ERI, may have prognostic value after ERI.

We separately described outcomes and treatment patterns of patients with resectable and unresectable RPS. Our findings suggest that eribulin should be considered a treatment option for unresectable RPS in clinical practice.
Moreover, BB-1701, a novel HER2-ADC containing eribulin as a payload, to which N87 AR cells are sensitive, exhibited antitumor effects in N87 AR cells in vitro and in vivo. These findings indicate that ABC transporter-mediated drug efflux is an important mechanism underlying T-DXd resistance in HER2-positive gastric and lung cancer models. Furthermore, our study suggests that both targeting drug efflux pathways and utilizing alternative payloads may be effective strategies for overcoming T-DXd resistance in HER2-positive gastric and lung cancers.
