Forty patients with intra-oral cancer were given cobalt-60 teletherapy upon the primary lesion.Among the physical advantages of this method are the more precise direction of the beam, reduced scatter and lessened skin and bone effects. The period of observation of patients treated has not been long enough to warrant discussion of cure or permanent arrest, but the consistency and regularity of disappearance of the primary lesion was significant. The authors believe that for intra-oral cancer, cobalt-60 teletherapy should be used before radical surgical procedures are proposed.
