In-human activity and pharmacology of homemade silver nanoparticles in highly refractory metastatic head and neck squamous cell cancer.

Background: Silver nanoparticles (SNPs) show high efficacy as targeted therapy against cancer cell lines, but have never been tested in patient clinical trials.Results: The patient ingested 120 ml daily of the solution for 3 months leading to clinical recovery and complete resolution of cancer at all sites, persisting for 18 months.
