Two Cases of Tongue Cancer Reappeared in the Irradiated Field More than 20 Years After Brachytherapy

Abstract

In the treatment of early-stage tongue cancer, brachytherapy has been considered a good indication of the point of preserving shape and function. In recent years, the number of long-term survivors after radiotherapy has increased, and secondary cancers in the irradiated field have begun to attract attention. Herein, we report here on two cases of radiation-induced cancer of the tongue developing after brachytherapy.
