Metastasis prevention by targeting the dormant niche #MMPMID25801619

Despite considerable advancements that shattered previously held dogmas about the metastatic cascade, evolution of therapies to treat metastatic disease has not kept up. In this Opinion article, I argue that rather than waiting for metastases to emerge before initiating treatment, it would be more effective to target metastatic seeds before they sprout. Specifically, I advocate directing therapies towards the niches that harbor dormant disseminated tumor cells in order to render them susceptible to cytotoxic agents. Treatment sensitization achieved by disrupting reservoirs of leukemic stem cells and latent HIV argues that this approach, though unconventional, could succeed in improving patient survival by delaying or even preventing metastasis.
