The authors declare no conflict of interest. To our knowledge, this increase in the incidence of hypopharyngeal cancers in elderly women has not been described to date. The incidence rise seems comparable to hypopharynx cancer in women, but the low incidence rates and the number of cases do not allow us to draw conclusions. Furthermore, according to the comparison of the incidences of the different cancers studied in the same population, such an increase has not been observed for men in other locations or in women for laryngeal cancers. Regardless of these evolutions, this study shows an increase in the incidence of OCC among elderly subjects in France since 1990, namely an increase in women aged 70 years or more and in men aged 80 years or more, with a slowdown in the decline in incidence among men aged 70 to 79 years over the 2000–2009 period. However, these evolutions are, to a large extent, taken into account in our analysis, notably because we present specific rates by age group and because this study is based on a comparison of the incidences of the different cancers studied in the same population.

Population aging and growth or alcohol and tobacco consumption alone do not seem to explain this increase, which is not observed in the same proportions for other upper aerodigestive tract cancer subsites sharing the same main risk factors.ĭuring the study period, the growth of the French population (from 57.9 million to 66.9 million) and the evolution of the average lifespan (from 72.7 years to 79.6 years for men and from 81 years to 85.5 years for women) during this study undeniably contributes to the evolution of the number of cancer cases. Conclusions: Since the 1990s, the incidence of OCC has been increasing in elderly subjects in France, particularly in women. Over the same period, for laryngeal and hypopharyngeal cancers, there was a decrease in incidence in elderly men and an increase in elderly women, although less marked than for OCC. As for men, there was a stabilization in the number of cases (+2%). Results: There was a 72% increase in the number of OCC cases in women over 70 years of age between the periods 1990–19–2018. The elderly population was divided into two groups: 70–79 years old and ≥80 years old. Incidence was modeled by a 2-dimensional penalized spline of age and year of diagnosis, associated with a random effect corresponding to the registry. Material and Methods: The incidence of cancers in mainland France from 1990 to 2018 was estimated from incidence data observed in every cancer registry of the Francim network. Objectives: To describe the evolution of the incidence of oral cavity cancers (OCC) among elderly patients in France between 19 and to compare it to the incidence of other cancers sharing the same main risk factors.
