Our study reports 282 oral cancer cases treated with 60Co-teletherapy (TCT), taken from 736 oral carcinomas treated with radiotherapy on the primary tumor from January 1959 to December 1970. They were mainly locally advanced cases which often had regional node involvement. In fact, during that period, the more advanced cases were submitted to TCT. There were only 9 (3.2%) patients with T1 lesions, while there were 134 (47.5%) T2 and 139 (49.3%) T3, T4 cases; there were respectively 106 (37.6%) and 44 (15.6%) N1 or N2 and N3 cases. Almost half of the patients were greater than or equal to 66 years old at onset of the treatment (138/282 cases, or 47.2%); the women were a small minority (18/282, or 6.4%). There were 58 (20.6%) carcinomas of the mucosal surface of the cheeks, 60 cases arising from the retromolar areas, the upper-lower alveolar processes and the hard palate (21.3%), 72 carcinomas of the mobile portion of the tongue (25.5%) and 92 arising from the floor of the mouth (32.6%). All the patients considered in the study were treated with conventional techniques by doses, field dimensions and fractionation. The overall results were objectively disappointing, even though they should be evaluated keeping in mind the nature and the gravity of oral carcinomas submitted to TCT. Actuarial survival at 5 and 10 years from the onset of treatment was respectively 11.6% and 6.4%. None of the N1, N3 cases survived beyond the fourth year from onset of the treatment. Long-term survival differs very little in relation to the site of origin in the oral cavity. Nowadays, TCT alone may have only a palliative role in the treatment of oral cancer, reserving it for those cases which, due to their extreme gravity or the various contraindications, do not permit more aggressive treatments. In a combined therapeutic approach the aim of TCT today is to control the minimum disease foci. Its association with surgery appears to be most effective.
