We present a retrospective study of the course of glottic cancer in a series of 302 cases. We studied the precise tumour localisation, the treatment carried out, the anatomico-pathological characteristics of the resected tissue and the results obtained as a function of the therapy used. It would seem important to stress the necessity of homogenizing the results of various authors by: presenting a series large enough for the results to be significant; there should be detailed total and prolonged follow up of patients, with use of similar evaluation parameters.
