Purpose:
@EN This study was designed to determine the efficacy of electron beam therapy in skin cancer.
@ES Materials and Methods:
@EN From January 1988 to March 1993, sixteen patients diagnosed as skin cancer of the face were treated by electron beam therapy at St. Mary's Hospital. There were 8 men and 8 women. The median age was 62 years and the range 45 to 80 years.
Twelve
(75%)
patients had basal cell carcinoma, and 4(25%) patients had squamous cell carcinoma. According to American Joint Committee(AJC) classification, 12(75%) patients had T1, and 4(25%) patients had T2. The median radiation dose was 5570 cGy in 5~7
weeks
(range; 3980-7000cGy). The median follow-up was 25.5 months with a range of 6 to 68 months.
@ES Results:
@EN 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 T1, and
75%(3/4) for
T2. Treatment induced complication was observed in 6.2%(1/16) Cosmetic outcomes were excellent to good in 93.8%(15/16) of patients.
@ES Conclusion:
@EN For the skin cancer, especially in the face, electron beam therapy was a safe and effective modality and offered excellent cosmesis.
