Arsenic likely to be powerful imaging agent in detecting cancers

"Long neglected as an awkward Cinderella, arsenic has great potential for new imaging agents and therapeutics based on multiple isotopes with diverse useful characteristics,” said Dr. Ralph Mason.

By UT Southwestern Medical Center, [RxPG] Arsenic linked to a drug that binds to the blood vessels of cancerous tumors provides a powerful imaging agent that could one day allow physicians to detect hard-to-find tumors and more closely monitor cancer’s response to therapy, researchers at UT Southwestern Medical Center have found.

The findings, based on animal studies and appearing in today’s issue of Clinical Cancer Research, mark the first time arsenic has been used to label antibodies for the detection of tumors.
