Disrupting the metastatic cascade: nanoparticle-based innovations in antimetastatic therapy

Antimetastatic therapy represents a transformative shift in oncology, addressing one of the greatest challenges in cancer care: the prevention and management of metastasis. By targeting the critical steps of the metastatic cascade and integrating them into multimodal treatment strategies, these therapies have the potential to greatly improve patient survival, enhance quality of life, and advance cancer care worldwide. Each stage of the metastatic cascade presents unique therapeutic vulnerabilities and opportunities for targeted intervention. Nanoparticle-based therapies have emerged as a promising frontier for disrupting the process of metastasis due to their ability to deliver therapeutic agents with high precision, reduce off-target effects of treatment, and overcome biological barriers. This review explores key targets suitable for antimetastatic therapy and recent advances in strategies using these modalities, highlighting their potential to improve treatment specificity and efficacy. By examining the integration of nanotechnology into antimetastatic therapy, we aim to underscore its transformative potential in combating metastatic cancer and improving patient outcomes.
