On June 26, 2009, the Radiation Safety Officer (RSO) notified DHS of a probable medical event that occurred on June 25, 2009 involving an HDR treatment to the esophagus. The authorized user intended to insert the applicator 2 cm past the distal part of the esophageal tumor. A GI specialist verified the location prior to treatment using a scope. Post treatment location of the applicator was reviewed using an AP lateral film. It was then realized that the applicator went 10 cm too far. The prescribed dose was 500 cGy. Therefore, a dose was given to a organ or tissue other than the intended treatment site that exceeds 0.5 Sv (50 rem) to an organ or tissue, and was 50% or more of the dose expected from the administration defined in the written directive (DHS 157.72(1)(a)(3.). DHS inspectors will investigate June 29, 2009.
