Purpose: This study was designed to determine the efficacy of electron beam therapy in skin cancer. Materials and Methods : From January l988 to March 1993, sixteen patients diagnosed as skin cancer of the face were treated by electron beam therapy at St. Marys HospitaL There were 8 men and 8 women. The median age was 62 years and the range 45 to 80 years. Twelve (75%) patietns had basal cell carcinoma, and 4(25%) patients had squamous cell carcinoma. According to American Joint Committee(AJC) classification, 12(75%) patients had Tl, and 4(25%) patients had T2. The median radiation dose was 5570 cGy in 5-7 weeks (range; 3980-7000 cGy). The median follow-up was 25.5 months with a range of 6 to 68 months. Results: The overall local control rate was 93.8% (15/16). By histologic classification, the local control rate was 91.7%(11/12) for basal cell carcinoma and 100%(4/4) for squamous cell carcinoma. The local control rate was 100%(12/12) for Tl, and 75%(3/4) for T2, Treatment induced complication was observed in 6.2%(l/16). Cosmetic outcomes were excellent to good in 93.8/(15 /16) of patients. Conclusion: For the skin cancer, especially in the face, electron beam therapy was a safe and effective modality and offered excellent cosmesis.
