In 1960-1987, 2387, 2352 cases of larynx cancer were treated and observed. In 1484 (63.1%) cases the cancer of the epiglottis was found, in 851 (36.2%)--in glottis and in 17 (0.7%) in subglottis. Cancers of supraglottis, in 60.0% cases. were in state III and IV of clinical advance and cancers of glottis in the same state were found in 20.6% of cases. Generally 52.4% of cases of epiglottis cancer were cured of and 74.4% of glottis cancer. Relative survivals were accordingly: 59.0% and 87.0%. In the period of 5-year observation 47.6% of cases of epiglottis cancer died and 25.6% died of glottis cancer.
