Our results suggest that patients feel unsupported and ill-informed about the possible risks of cardiac damage from Trastuzumab. This has implications for the self-management of symptoms and mitigation of risks for cardiac damage and suggests the need for improvement in patient care.

In contrast, the other patient showed limited response, with persistent complex CICs, which led to an adjustment of the adjuvant regimen. These observations suggest that dynamic cell-in-cell (CIC) patterns may reflect heterogeneous tumor responses to NACT, providing insights for individualized treatment planning.

Nonetheless, primary and acquired resistance driven by HER2 heterogeneity, immune evasion, and dynamic molecular evolution remain major challenges. Next-generation HER2-targeted therapies, including bispecific antibodies, novel antibody - drug conjugates, and dual HER2 antibodies will be crucial to further improve outcomes in this population.

These findings establish avisomes as a highly promising theranostic platform for HER2-positive breast cancer. Its genetically encoded, self-assembling nature eliminates the major limitations of ADCs and synthetic nanoparticles, providing a scalable, reproducible, and cost-efficient alternative for next-generation targeted cancer therapy.
