To determine the survival rate and analyse the predicting factors of recurrence in patients with unilateral, clinically T2N0 squamous cell carcinoma (SCC) of the tongue which does not cross the midline, a retrospective analysis of 32 such consecutive, previously untreated, cases was performed. All patients were initially treated by surgery between January 1992 and May 2004. All patients had neck dissections: 12 continuous, 20 discontinuous, 24 bilateral and 8 unilateral. Fourteen patients (44%) received adjunctive postoperative radiotherapy. Occult metastatic rates were 34% and 4% in ipsilateral and contralateral neck, respectively. Patients with pN0 cancer had a better 5-year disease-specific survival rate than those with pN+ cancer (85% versus 41%, P = 0.005). Twelve patients (38%) had recurrences after the initial treatment. The recurrence rate was significantly higher in patients with pathologic nodal metastasis, peroral resection of the primary tumour or discontinuous neck dissection. The results suggest that the most effective surgical methods for treating unilateral T2N0 SCC of the tongue which does not cross the midline are: pull–through approach for primary lesion instead of peroral approach; continuous rather than discontinuous neck dissection and ipsilateral elective rather than bilateral routine elective neck dissection.
