EFFICACY OF MOHS" SURGERY IN PATIENTS WITH SKIN CANCER: (AL-ZAHRA HOSPITAL; SEP. 1999 - DEC. 2000)
Abstract
Introduction: Modified Mohs" Surgery (MMS) has not ever been performed for management of skin cancers in Iran. The aim of this study was evaluation of the efficacy of MMS in recurrence, metastasis rate and cosmetic results.
Methods: Fifty one patients with known indications for MMS were selected. They were operated under standard method of MMS, followed and evaluated for a 12 months period about recurrence, metastasis and cosmetic results.
Results: 58 tumors from 51 patients were operated. 27.5 percent of patients were females and 72.5 percent were males (57.4± 13.4 year). Eight percent had more than one tumor. In 84 percent, MMS was the first treatment procedure. Anatomically lesions of scalp and face, trunk, and limbs constituted 92.5 percent, 1.9 percent, and 5.6 percent, respectively. Mean size of lesions was 16.9 mm (range: 4-70). The number of layers to clear the tumors was 1-5 (mean: 1.5). Histologically 81 percent of lesions were BCC, 9.4 percent SCC. Immediate reconstruction was performed in all patients as follows: 37 percent primary simple closure, 5.5 percent secondary healing, 50 percent skin flaps, 3.7 percent skin grafts and 3.7 percent a combination model. The percent of relative frequency of recurrence was 3.7 with no case of metastasis. Cosmetic results were excellent in 35 percent, good in 50 percent, intertmediate in 11.5 percent and poor in 3.5 percent of cases.
Discussion: Despite paucity of patients" number, higher incidence of tumors in males of 50 or more, higher occurrence on scalp and face and most frequently occurring as BCC is prominently evident. One year recurrence rate of 3.7 percent is probably due to paucity of patients. Cosmetic results were mostly favorable (85 percent), and unfavorable results were due to secondary healing and large facial lesions repaired with flaps. For more valid evaluations, long term studies with greater number of patients is recommended.
