MEDICAL EVENT
The following information was provided by the licensee via phone:
On March 3, 2026, at 1038 EST, a 200 mCi Lu-177 Lutathera treatment for a metastatic neuroendocrine tumor had commenced when the patient informed the treatment team that he had received an injection that morning. It was determined that the patient had been administered an octreotide injection. The physician ordered an immediate stop to the Lutathera infusion as the octreotide would prevent take-up of the Lu-177. Only 19 mCi of the planned 200 mCi dose was administered.
A Medical Event may indicate potential problems in a medical facility's use of radioactive materials. It does not necessarily result in harm to the patient.

AGREEMENT STATE REPORT - EQUIPMENT FAILURE
The following information was provided by the Wisconsin Department of Health Services via email:
"The University of Wisconsin Madison (UWM) reported an equipment failure involving a Y-90 TheraSphere microsphere administration set (lot A182) which occurred on March 4, 2026. UWM reported the tubing was damaged when it was removed from the priming line and was unable to be connected to the patient's catheter. Since the dose vial had already been punctured in the set-up, the therapy was cancelled.
"The administration set was disassembled so that the dose vial could be put into waste without releasing any of the spheres. The faulty connectors were removed and given to the manufacturer's representative who was present. The UWM found an additional administration set from the same lot; this was pulled and will not be used. Areas of possible contamination were surveyed, and none were found."
