title: [Factors affecting local and regional control and survival of carcinomas of the tongue and floor of mouth].
abstract: A retrospective study of 142 patients that had previous surgery for carcinoma of the tongue or floor of mouth looking into the factors that affect significantly the evolution of our patients and in which circumstances we could benefit from new therapeutic techniques. Cause specific survival at 3 and 5 years was 63.4% and 56.9% respectively. Recurrences were found locally in 32 patients (22.5%), regional in 32 (22.5%) and metastasis in 11 (7.4%). T staging had no did impact on local recurrence, but the presence of positive margins (p = 0.0323). Regional control for N0/N1 was 85% (90/106) versus 55.5% (20/36) for N2/N3 (p = 0.001). Regional control by N staging was 84.5% (73/86) for N0, 85% (17/20) for N1, 57% (30/35) for N2 and 0% for N3 (0/1). Both, N staging and number of positive nodes had a significant impact in specific survival. Positive margins and the presence of positive nodes have the greatest impact on survival and regional control. Adjuvant postoperative radiotherapy did not increase survival, but not prospective random selection was performed. To evaluate this.
