[Soft radiotherapy of lip cancer]

Reported are 107 patients with 109 carcinomas of the lip. Histologically 83 per cent of the patients had well or moderately well differentiated tumors. With total tumor doses between 6,000 and 9,500 R, in some patients with more than 10,000 R, 92 per cent of patients were cleared, in 88 per cent with a good cosmetical, and in 77 per cent with a good functional result. The used radiation methods are discussed under consideration of time-, dose- and fractionation-factors of Orton and Ellis. Patients should be controlled for a longer period than five years, because recurrences or second tumors are possible even after this time.
