Predictors of recurrence after radiotherapy for non-melanoma skin cancer

摘要

Predictive factors of recurrence were examined in 448 non-melanoma skin cancers (72% basal cell carcinoma, 28% squamous cell carcinoma) treated with radiotherapy. The overall recurrence rate was 15.8% at a median follow-up of 18.4 months. In multivariate analysis, significant factors for recurrence were age (p = 0.0197), tumour size 2 cm or greater (p = 0.0095), immunosuppression (p = 0.0082), and treatment modality (p = 0.0009).
