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%.
