[The importance of local administration of 5% 5-fluorouracil in the therapy of senile keratoses and basocellular carcinoma].

The results of the local application of 5-fluorouracil in the form of cream ("Efudix" Roche) in the therapy of senile keratoses and basocellular carcinomas were presented in this paper. A total of 205 changes of senile keratoses and 27 changes of basocellular carcinomas were treated in 90 patients. The cream was put on changes of senile keratoses without covering two times daily during a three--week period on the average up to the appearance of erosion. In cases of basaloma the cream was administered in the form of occlusive bandage with the duration of six hours each day. The treatment was undertaken until the appearance of ulceration and lasted three weeks. In all treated cases after the appearance of erosion and ulceration cream for epithelization was applied in further therapy. Out of all 232 treated changes either of senile keratosis or basaloma, successful treatment was attained in 230 (99.15%) cases and in only 2 cases of nodous basaloma successful treatment was not attained which accounted for 0.85% of treated lesions. Cosmetic results of the treatment were excellent. The appearance of relapse was not observed in any case during a three--year period.
