Carcinoma of the hypopharynx: Analysis of incidence and survival in Sweden over a 30-year period

Background The aim of the study was to analyze whether there were any changes in incidence and prognosis of hypopharyngeal carcinomas diagnosed between 1960 and 1989 in Sweden. Methods Data of primary hypopharyngeal malignant tumors reported to the Swedish Cancer Registry were collected. The total n...

Description
Summary:Background The aim of the study was to analyze whether there were any changes in incidence and prognosis of hypopharyngeal carcinomas diagnosed between 1960 and 1989 in Sweden. Methods Data of primary hypopharyngeal malignant tumors reported to the Swedish Cancer Registry were collected. The total number of cases was 2012, 1396 men and 616 women, and the end of follow‐up was December 31, 1992. Results For women, a significant decrease in the age‐standardized incidence (ASI) was seen, with an average decrease of 2% per year (p < .001), which was most evident in rural counties. The male patients, on the contrary, showed a significant increase of about 1.5% per year (p < .001); the metropolitan areas had an ASI about twice that of more‐rural areas. The 2‐ and 5‐year overall survival was poor, only 25% and 13%, respectively. For women aged
