An epidemiological study is made of the evolution of cancer of the larynx in the Valencia Community (Spain) in comparison with the nationwide situation, during the period 1977-1985. Both morbidity and mortality are evaluated based on the data published by the National Institute of Statistics (Instituto Nacional de Estadística INE). Indirect data standardization was decided on, given the lack of information by age groups. The results reveal an increase in the incidence during the study period in all provinces--both morbidity and mortality standing out in the province of Castellón; in Alicante the figures were lower in comparison with the national values.
