[Cancer of the larynx and discriminant analysis].
In order to get the prognosis on the 5 years survival, free of disease, in a sample of 428 laryngectomies, for cancer of the larynx, the AA. have realized a discriminant analysis working out with several known factors. Only from 109 components of the group complete information could be available about the variables studied and with these a linear discriminant function was obtained. The rate of correct prediction was 78.8 percent for cancer recurrence and 77.6 percent for survival without recurrence after 5 years term. The discriminant variables were: positive lymph nodes, tumour staging using TNM classification, cord mobility and alcohol consumption.
