UNASSIGNED: Background @entity957 of the @entity135 ( @entity213 ) comprises a variety of @entity5 . Due to the rarity of each individual malignant entity, knowledge of epidemiological changes and trends over time may be derived from data compiled in regional and national registries. This study analyzed the development in incidence rates and mortality in elderly @entity213 @entity1 in Denmark between 1980 and 2012 with specific attention to compliance to radiotherapy, the main treatment modality of @entity213 in Denmark. Material and methods @entity213 consisting of more than 25 @entity1 per year over the age of 70 years were analyzed. This included @entity1697 defined as ICD-codes C00.3-4, C02-04, C05.0, C06; oropharynx as C01, C05.1-9, C09-10; and larynx as C32 recorded in the NORDCAN database. Additional data from the DAHANCA database was added to assess differences in compliance to treatment between younger and older @entity1 groups. Results @entity213 was predominant in younger @entity1 . Only 17% were older than 70 years. The median age was 60 years. Generally, incidence rates rose for @entity1697 and oropharynx between 1980 and 2012 and stabilized for @entity5 . Mortality rates had a shallower increase, especially in younger age groups, which translated into improved age-specific survival rates. Compliance to radiotherapy was high for all age groups. Failure to receive at least 60 Gy during radical radiation treatment was 2.3% despite a significant increase in @entity1 with poor WHO performance status over time. Conclusion @entity213 is a @entity395 in @entity1 above 70 years accounting for only 17% of all @entity213 @entity1 . Incidence rates increased over time, but age-specific survival rates improved, especially in younger @entity1 . Failure rates to comply with radiation treatment, however, were low in both young and elderly @entity1 .
