ABSTRACT
BACKGROUND:
The sub-site predilection of head and neck squamous cell carcinoma (HNSCC) reflects the risk profile of a community and there are suggestions that these are changing over time.OBJECTIVE:
To determine the change in head and neck cancer in rural and urban populations in India.METHODS:
Cancer registry data of an urban and a rural population were reviewed over a period of 13 and 11 years, respectively. Age adjusted rates (AAR) and age specific incidence rates were used for data analysis.RESULTS:
Oral cancers formed the majority of the head and neck cancers with a predilection for tongue, except in rural males, in whom the pharynx was the predominant sub-site. Overall there was a reduction in the incidence of HNSCC, which was more pronounced in urban females and rural males (p< .001). Among the sub-sites, oral cavity cancers showed a decreasing trend in urban females (p< .01) and rural males (p< .01). However, the trend was towards increase of incidence of tongue cancers. Pharyngeal cancer showed reduction in urban females (p< .01), whereas it increased in rural females. The recent increase in incidence of young adults with HNSCC reported in developed countries was not observed.CONCLUSIONS:
Overall, incidence of HNSCC is reducing. This may be attributed to the decreased prevalence of tobacco use.The increase in incidence of tongue cancer may suggest factors other than tobacco and alcohol in its genesis.
