ONCOLOGY: Small but powerful cancer probe

Nanoparticle-based materials are under development for many clinical uses; for example, they are being developed for use as drug-delivery vehicles and diagnostic probes. However, many such materials currently under evaluation in oncology clinical trials are not tumor selective. Now, a team of researchers, led by Michelle Bradbury, at the Sloan-Kettering Institute for Cancer Research, New York, has characterized an approximately 7-nm diameter multimodal silica nanoparticle that is tumor selective and nontoxic. Importantly, the team used these particles to image tumor spread in a spontaneous skin cancer miniswine model. The authors therefore suggest that their data highlight the potential of these cancer-selective silica nanoparticles for determining disease spread in the clinical setting, something that could become a reality sooner rather than later because the nanoparticles were recently approved for a first-in-human clinical trial.
