Keywords:
HDSCC, KUD, AAR, CR, CarcinomaAbstract
Background: Head and Neck cancers are basically squamous cell carcinomas. It is the fifth most common cancer and the sixth most common cause of cancer mortality in the world. Incidence of cancer as a whole for all sites is fourth highest in Kamrup Urban District (KUD) in males (AAR 185.2) and second highest (AAR 156.3) in females out of all Population Based Cancer Registries (PBCR) in India. Incidence of head and neck cancers in KUD is quite high both nationally and internationally. This retrospective study was carried out to assess the incidence pattern of head and neck cancers in Kamrup Urban District of Assam, India for the period of 2009-2011.
Methods: Cancer is not notifiable in India, so method of collecting information on cancer was active in PBCR Guwahati. A total of 4416 cases were registered during the three years (1st January 2009- 31st December 2011) of which 2508 were male and 1908 female. Statistical analysis used: Age Adjusted Rate (AAR), Crude Rate (CR) and Population pyramids are provided by NCRP-ICMR.
Results: The relative proportion of head and neck cancers of total cancer cases registered in KUD constitutes 26% (654/2508) and 12% (225/1908) in male and female respectively. In males cancer of hypopharynx (AAR 14.7) was most common followed by tongue (AAR 9.4) and mouth (AAR 7.7). In females cancer of mouth (AAR 7.6) is most common followed by cancer of tongue (AAR 3.2).
Conclusion: The pattern and incidence of various head and neck cancers is of utmost importance for primary prevention and early detection to adequately manage these cancers comprehensively in the community.
