The following report was received via e-mail:
1. A patient received an [Ir-192] HDR treatment using a skin applicator on the nose. This treatment is used to treat skin cancer.
2. The physician's written directive specified a dose to the tumor volume, and a maximum tumor dose of 130 percent of the prescribed dose. The total dose was delivered in 8 fractions.
3. The patient's course of treatment proceeded to conclusion. On recent follow-up exam, the patient's skin reaction was more than usual for this type of treatment, so the physician asked physics to review the plan.
4. This review indicated the tumor volume maximum dose exceeded the prescribed 130 percent by more than 50 percent.
The date, time, and dose prescribed/received were not given in the report.
