INTRODUCTION: Delayed reconstruction (two-step surgery) comprised of tumor resection and repair three or four days later, after paraffin tissue fixation and histopathological examination, is one of the techniques used for complete excision of spreading cutaneous carcinomas. PATIENTS AND METHODS: In order to evaluate the efficacy and long term prognosis of delayed reconstruction surgery, we carried out a retrospective study of 80 patients treated by this method and (Kaplan- Meier) for correlation with the local recurrence rate: sex, age, anatomic site, histologic type and existence of previous therapy. Long term results have been estimated. Among the 80 patients studied, 76 patients have been followed. The sex-ratio was 0.48. Fifty-two percent of the population was more than seventy years old. Fifty-five percent of the tumors were situated on the nose. In 32,5 p. 100 of the cases, a prior therapy (surgery, electrodessication or radiation therapy) has been carried out. Histological analysis showed 87 p. 100 basal cell carcinomas (of which 26 p. 100 of morpheaform basal cell carcinomas) and 13 p. 100 squamous cell carcinomas. RESULTS: After the first operative step, there was total excision in 69 p. 100 of thecases. In the remaining cases, a second excision was performed with a margin of normal tissue. Recurrences were observed (some precocious recurrences and some late recurrences) in 18.4 p. 100 of the cases. No risk factor correlated significantly with the recurrence rate. However, analysis of the survival graph suggests that the squamous cell carcinomas recurred more often than the basal cell carcinomas. CONCLUSIONS: Although extemporaneous examinations (Mohs' technique) remains the gold standard technique in the management of spreading cutaneous carcinomas of the face, the delayed reconstruction (two-step surgery) is a credible alternative when compared to the recurrence rates reported in the literature with the other techniques (electrodessication, radiation therapy or cryosurgery).
