title: Invasion of cartilage by basal cell carcinoma.
abstract: Extensive analysis of ten factors in 183 consecutive cases of basal cell carcinoma overlying cartilage of the nose and ear is performed in this prospective study. Duration of tumor and prior treatment rather than one specific modality of previous therapy are significant factors in predicting tumor invasion of cartilage, which necessitates removal of cartilage.
