Stimulated by the results obtained with massive doses of roentgen rays used superficially in malignant conditions of the skin and lip, the doses for the lip conforming to the method advocated by Pusey, Martin,1 Grier and others, we sought a method which would enable one to use the same energy within the oral cavity. Two years ago we began the superficial use of roentgen rays for this purpose. Although in January Stecher and Loughery2 published a report on the "Direct Roentgen Irradiation of Intracavitary Neoplasms," our work was independent, and we had no knowledge of their efforts.
We believe that some of the results that we obtained with this method in intra-oral malignant conditions justify this communication.
To make certain that the application is effective, two important difficulties must be overcome: (1) the protection of the unaffected structures and (2) the stabilization of the affected part. For this
