NEW YORK (TheStreet) -- IsoRay  (ISR) surged Wednesday after the company announced significant results for its cesium-131 isotope in early clinical interstitial implants for gynecologic malignancies.

The first major published peer study showed improved results with IsoRay's cesium-131 seeds in treating gynecological cancer. The study found 84.4% local control with a 12 month median follow-up, which surpassed other previously published rates of 33% and 63%.
