Subsite- and histology-specific epidemiology of head and neck cancers in Japan from 2016 to 2019: an application of a new classification of rare cancers
The research aims to analyze the incidence of head and neck cancers using a new classification for rare cancers.
Analyzed cancer incidence data from Japan between 2016 and 2019
Classified head and neck cancers based on site and histology
Compared incidence trends over the specified period
Most head and neck cancers were categorized as rare during the study period
Highlighting the need for improved tracking of incidence trends
Results indicate evolving definitions in pathology impact cancer classification
Abstract
Most head and neck cancers were rare during the study period. This result highlights the importance of continued efforts to track incidence trends in parallel with evolving pathological definitions.
