Abstract

Objectives: To evaluate changes in incidence and survival of patients diagnosed with hypopharyngeal cancer (HPC) in Denmark in the period 1980-2014.Methods: All patients registered with HPC in the Danish Cancer Registry (DCR) in the period 1980-2014 were included. Age-adjusted incidence rates (AAIRs), average annual percentage change in incidence, and overall survival were calculated.Results: Two thousand and nine patients were included (79.7% men). The overall AAIR increased significantly from 0.3 per 100,000 to 1.1 per 100,000 during the study period, corresponding to an increase of 4.1% per year. The most frequent histology was squamous cell carcinoma (SCC) comprising 90.3%. The overall five-year survival increased with 13.5 percentage points from 13.4% in the period 1980-1985 to 26.9% in the period 2010-2014. Women demonstrated better survival compared to men with a hazard ratio of 0.83, and patients with SCC had better survival compared to the remaining histology groups.Conclusions: This nation-wide study, covering nearly four decades, showed a significant increase in incidence and survival of HPC in Denmark.
