Carcinoma of the oral tongue: A study of patient selection and treatment results

Retrospective review of 118 primarily treated cancers of the oral tongue was done to study patient selection and to search for improved treatment strategies. Small surface lesions were treated by local excision (LE); most small lesions invading muscle of the tongue without lymph node metastases were treated by radiation alone (RA) while larger lesions and those with palpable nodes were treated by preoperative radiation and surgery (R + S). Ultimate control of the primary tumor and lymph nodes after initial treatment and surgical salvage was high for the lesions by LE (91%), the T1N0 lesions treated by RA (88%) and for the TxN+ lesions treated by R + S (57%). Improved treatment strategies are suggested for T2N0 lesions treated by RA because of poor tumor control (53%) and a high rate of radiation complications (25%), and for T3N0 lesions because so many of these patients died from causes other than cancer within two years. Second primary cancers were most common in those patients with a good prognosis.
