Irradiation of the pinna with superficial kilovoltage radiotherapy.
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.
