Single-agent phototherapy system offers significant new tool to fight cancer

Researchers at Oregon State University today announced an important advance in the field of cancer imaging and phototherapy, using a single-agent system that may ultimately change the efficacy of cancer surgery and treatment around the world. The newest approach developed at OSU uses a single chemical compound, silicon naphthalocyanine, which has both diagnostic and therapeutic value. It makes cancer cells glow when exposed to near-infrared light, so a surgeon can identify the cancer and more effectively remove it. At the same time, this compound creates heat and reactive oxygen species within any remaining cancer cells, killing them. In tests completed with laboratory animals, tumors were completely eradicated without side effects, and did not return.”
