title: Changing aspects in the treatment of squamous cell carcinoma of the oral tongue.
abstract: Two groups of patients were compared. In group 1, consisting of 304 patients treated from 1958 to 1972 (minimum observation time of 5 years), the local and regional control rate was 35 per cent. In group 2, consisting of 126 patients treated 1978 to 1983 (median observation time of 58 months), the local and regional control rate was 60 per cent (p less than 0.0001). The local and regional control rates were improved for all stages, but the differences were significant only for stages T1N0, T2N0, T3N0 and TXN2,3. The actuarial survival rates also showed improvement in group 2 patients. The incidence of treatment failure, with regard to the neck alone or tongue and neck combined, decreased from 51 per cent to 27 per cent with the newer techniques. The greatest improvement was observed in patients with T1N0 and T2N0 tumors. There was also a decrease in the failure rates in patients with the more advanced tumors.
