title: [Labelling index in breast cancer and in upper respiratory and digestive tract cancer (author's transl)].
abstract: The labelling index (LI) of 96 breast adenocarcinomas and of 43 upper respiratory and digestive tract cancers has been measured. For the two histological groups, the distribution of individual values is found to be log-normal, with a mean value depending on the tumour type. Our data have been compared with other authors results. The dispersion of individual values within a same histological type suggests that the LI is interesting as an individual value depending on the patient and his own cancer. For breast adenocarcinomas the LI values obtained have been separated in two groups depending upon the patient age, the age of 53 has been chosen to separate premenopausal from post-menopausal patients. A test of significance showed that the two corresponding log-normal distributions were different, even at the 0.01 level of significance, a mean LI value thus characterizing each distribution.
