Abstract

This 5-year prospective study evaluated histologic criteria as predictors of tumor recurrence for the individual with a "positive-margin" basal cell carcinoma. The results demonstrated that 93 percent of patients with greater than 75 percent of their tumor cords containing irregularities in in the peripheral palisade had tumor recurrence, while no patient with less than 25 percent of their tumor cords containing irregularities in the peripheral palisade developed a recurrence in 5 years of follow-up. After statistical analysis for the other histologic variables, the presence of greater than 75 percent irregularities in the peripheral palisade conferred a 39-fold increased risk of tumor recurrence, significant at the p << 0.001 level. For the patient in the intermediate group (25 to 75 percent irregularities in the peripheral palisade), the presence of a weak host response (absent to minimal infiltration of small lymphocytes) increased the risk of tumor recurmire fourfold, with this flit-e l being significant at the p < 0.05 level. The presence of tumor ulceration conferred a 2.8-fold increased risk for tumor recurrence, significant at the p < 0.01 level, while the presence of squamous differentiation conferred no increased risk. This study may provide a valid basis for predicting tumor recurrence in the individual with a positive-margin basal t ell carcinoma.
