During the same period, mortality decreased only 43% from 1.59 per 100\u202f000 people (95% CI, 1.53-1.64 per 100\u202f000 people) to 0.89 per 100\u202f000 people (95% CI, 0.86-0.92 per 100\u202f000 people). This corresponds to a 25% relative increase in case-fatality rate. Examination by stage showed a decrease in the incidence of localized disease at diagnosis of 40% from 2.65 per 100\u202f000 people (95% CI, 2.44-2.89 per 100\u202f000 people) to 1.60 per 100\u202f000 people (95% CI, 1.45-1.76 per 100\u202f000 people) from 1986 to 2002 and of 45% from 2.15 per 100\u202f000 people (95% CI, 1.98-2.34 per 100\u202f000 people) to 1.19 per 100\u202f000 people (95% CI, 1.08-1.31 per 100\u202f000 people) from 2005 to 2018. Distribution of larynx cancer by subsite remained stable, with most cases affecting the glottis. The proportion of patients receiving surgery as their first course of treatment decreased regardless of stage at presentation.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"ab-ooi220075-9\">\n                    <jats:title>Conclusions and Relevance<\/jats:title>\n                    <jats:p>In this cohort study, between 1986 and 2018, the incidence of larynx cancer decreased in the US, primarily because of the decrease in the incidence of localized disease. Mortality did not decrease similarly, resulting in an increased case-fatality rate overall. Encouraging earlier referrals for cancer concern, focusing resources where larynx cancer rates remain highest, renewing attention to research on new biologic causes of different tumor biologic characteristics, and conducting trials to directly compare treatments may help reverse this trend.<\/jats:p>\n
