Abstract:
Amidst escalating global health challenges, neoplastic diseases remain a predominant cause of morbidity and mortality, exerting complex and far-reaching effects on human health and societal well-being. The advent of precision medicine has ushered in an era of tailored therapeutic strategies, leveraging individual genetic profiles, tumor microenvironmental features, and exogenous factors to redefine oncology care. Central to these advances is the understanding of cell death, a fundamental biological process encompassing both programmed and non-programmed forms. Programmed cell death is orchestrated through sophisticated genetic and molecular mechanisms. Emerging evidence underscores the role of metal ion dyshomeostasis, particularly of iron, copper, zinc, sodium, magnesium, manganese, and calcium, in disrupting intracellular signaling and metabolic equilibrium, thereby inducing lethal cascades in malignant cells. Concurrently, innovations in nanomedicine have enabled precise modulation of ion fluxes within tumors, enhancing therapeutic specificity while minimizing systemic toxicity. This confluence of ion-mediated cell death mechanisms and nanotechnology not only exemplifies a transformative approach in cancer treatment but also aligns seamlessly with the tenets of precision medicine, offering novel pathways for therapeutic innovation and clinical translation.
