title: Irradiation of the pinna with superficial kilovoltage radiotherapy.
abstract: Excellent local control can be achieved by treating superficial carcinomas of the skin with superficial kilovoltage radiotherapy. The results of this study support the use of 100-140 KV photons to treat carcinomas of the skin of or around the pinna. This achieves a local control rate of 97% and the radionecrosis rate of 10% could be halved if all patients were treated with 3500 cGy in 5 fractions over one week, or to a maximum area of 5 cm2 of irradiated pinna. An audit of the running cost reveals that this method of treating superficial carcinomas is highly cost effective and can be recommended for all suitable patients.
