Pretargeted radioimmunotherapy: what is it and how can it fight colon cancer?


"Pretargeted radioimmunotherapy" might be a mouthful to say, but recent research shows that it may be a really effective tool to fight colon cancer. 

Presenters at the 2016 Annual Meeting of the Society of Nuclear Medicine and Molecular Imaging (SNMMI) detailed their new cancer-fighting technique called "pretargeted radioimmunotherapy" or "PRIT". They used the technique in a mouse study that showed the technique was highly effective.

So, what is "PRIT"? Imagine that all cells in your body are houses with a unique mailing address. Colon cancer cells have a specific address that is different from other healthy cells. Scientists can ship a package of radiation addressed specifically to a colon cancer cell. Then, the radiation kills the cell. 

Sarah M. Cheal, the presenting author from Memorial Sloan Kettering Cancer Center in New York, N.Y. seemed optimistic about the possibilities for the treatment: "If these results can be replicated in prospective human studies, this multi-platform approach could be used with an array of antibodies to treat a number of cancers, especially colorectal and ovarian cancers."

According to Cheal, if validated in human trials, these techniques could be available in as little as five years.
