Abstract
We conducted a retrospective review of the prognosis for patients with local recurrence after surgical treatment of carcinoma of the tongue. Glossectomy for squamous cell carcinoma of the tongue was performed in 167 patients. Local recurrence developed in 32 patients including 21 with local recurrence alone, 10 with locoregional recurrence and one with locodistant recurrence. The incidence of local recurrence increased with tumor stage (from 16% of T1 tumors to 46% of T4 carcinomas). Eleven (34%) patients underwent surgical salvage for local recurrence, with only one (9%) patient surviving free of carcinoma at 43 months post-surgical salvage. All of the remaining 21 patients with local recurrence were treated palliatively and all died within one year. Patients who underwent surgical salvage had significantly higher survival rates compared to those treated palliatively. Close follow-up after glossectomy is important for early detection of local recurrence amenable to surgical salvage. However, the overall prognosis for patients with local recurrence was poor, with a three-year actuarial survival rate of only 3%. Therefore, prevention of local recurrence with adequate initial surgical treatment is essential.
