• Four hundred fourteen primary cutaneous squamous cell carcinomas were treated by microscopically controlled excision. A five-year mortality-table adjusted cure rate of 93.3% was achieved. The following six parameters were analyzed for correlation with the local recurrence rate: sex, age, lesion diameter, history of previous therapy, anatomic site, and number of stages of Mohs' surgery required for treatment. Only the number of stages correlated significantly with the recurrence rate. However, subpopulations at high risk for recurrent disease could be identified. These consisted of male patients younger than 60 years of age, male patients requiring five or more stages of Mohs' surgery, and patients of either sex with carcinoma of the lower extremity. Modifications of microscopically controlled excision may be warranted in selected patients.
