Methods Retrospective analysis of 86 patients with T1-2N0-1 OSCC who received surgery between January 2000 and December 2006. Fourteen patients received postoperative radiotherapy PORT . Patient characteristics tumor characteristics treatment modality failure patterns and survival rates were analyzed. Results The median follow-up was 45 months. The five-year overall survival OS and disease-free survival DFS rates were and respectively. Higher tumor grade and invasion depth cm were the significant prognostic factors affecting five-year OS and DFS OS rate 65 vs. 91 p for grade 66 vs. 92 p for invasion depth DFS rate 69 vs. 88 p for grade 66 vs. 92 p for invasion depth . In the risk group there was no local failure in patients with postoperative radiotherapy. Conclusions In T1-2N0-1 OSCC factors that affected prognosis after primary surgery were higher tumor grade and deep invasion depth over cm. Postoperative radiotherapy should be considered in early oral tongue cancer patients with these high-risk pathologic features. Background The oral tongue is the most common subsite for squamous cell carcinoma of the oral cavity excluding the lip 1 . In advanced cases surgical resection followed by radiotherapy RT with or without chemotherapy is performed and it seems to be beneficial. In early cases T1-2 surgery is often the preferred form of treatment 2 . .
