Utah Division of Radiation Control via facsimile:
The Utah Division of Radiation Control was notified at 11:45 a.m. MST on Thursday, January 17, 2013 of a medical event associated with a radioembolization brachytherapy treatment of liver cancer. Notification was provided by the licensee's Radiation Safety Officer. This incident report is the initial notification to the NRC Operations Center.
The licensee's radiation safety officer reported to the Division that the treatment plan prescribed 1.33 GBq of yttrium-90 for treatment of liver cancer. The patient received 0.798 GBq of yttrium associated with the TheraSphere product. After the administration of the dosage, a nuclear medicine technologist determined that the total prescribed dosage was not delivered to the patient, as radioactive material was found to remain in the dosage vial and the administration apparatus. The licensee is working with the manufacturer of the treatment delivery system to determine the cause of the medical event.
