We retrospectively reviewed 52 tongue cancer patients who received definitive treatment at Shiga University Hospital between January 1993 and August 2004.
In cases of T1 and early T2 (early T2: ≦3 cm), partial glossectomy was performed. Radical operation followed by reconstructive surgery was performed after pre-operative chemotherapy in cases of advanced T2 (advanced T2: >3 cm), T3 and T4. Post-operative radiation was performed in some cases to prevent local and cervical recurrence.
The 5-year survival rates by the Kaplan-Meier method were 92% in stage I, 88% in stage II, 73% in stage III, 55% in stage IV, and 72% overall, respectively. The 5-year survival rates by the size in T2 cases were 90% in early T2 and 46% in advanced T2. Twelve cases were relapsed. Locoregional recurrence occurred in 11 patients (5 cases at the primary site, 6 in the neck), and distant metastasis in 4 patients. Long-term survivors after secondary treatment were 3 of 11 cases with recurrence at the primary site.
The results of salvage treatment for recurrent cases were discouraging. Adjuvant chemotherapy and post-operative radiotherapy are recommended for advanced tongue cancer.
