[Radiotherapy of cancer of the lower lip]

The authors assessed the results of radiotherapy including tele- and brachytherapy (taking into account a cosmetic effect) of 261 patients with lower lip cancer (stage II in 160 patients and stage III in 101 patients). Teletherapy at a summary focal dose of (SFD) 20-24 Gy and a single focal dose (SFD) of 2 Gy was followed after 2-week interruption by brachytherapy, the SFD being 50-65 Gy mostly 50-55 Gy. An irradiation field size (0.5-1 sm from visible tumor limits) and SFD were determined by a stage of disease and infiltration depth. The cure rate during a 3-year follow-up in stage II was 91.2% in stage III--62%.
