AGREEMENT STATE REPORT - UNDERDOSE MEDICAL EVENT
The following information was received via e-mail:
"The City of Hope Radiation Safety Officer contacted LA County Radiation Management (LA County) on May 10, 2022 to report a Medical Event that occurred on the same day at City of Hope in Duarte, CA. The patient was underdosed during a Selective Internal Radiation Therapy (SIRT) treatment for liver cancer that involved the administration of SIR-Spheres yttrium-90 (Y-90) resin microspheres. The prescribed dose to the patient was 10 mCi, but the dose delivered to the patient was only 6.42 mCi due to a leakage caused by a loose tubing connection.
"City of Hope will conduct an investigation to gain a better understanding of the details of the event."
California 5010 Number: 051022
