XXXX in the USA, SEER 1992-1999. An epidemiological study with 6830 cases.

@entity1 @entity5 @entity358 @entity3 @entity4303
Most of our knowledge on the epidemiology of @entity5 in the USA relies on studies updated during the 1980s. The aim of this study was to describe USA population-based case-series incidence in the period 1992-1999. Data were retrieved from a Surveillance Epidemiology and End Results (SEER) Program public-use file. Incidence rates, male-to-female standardized ratios, estimated annual percentage changes and 5-year relative survival rates were computed, and 6830 malignant @entity4303 incident during 1992-1999 were analysed. The overall age-adjusted incidence rates were 1.9 per 100 000 for @entity1 and @entity1 . There was an excess in @entity1 for @entity358 , while rates were higher among @entity1 for carcinoids of the small intestine and rectum. From 1992 to 1999, incidence rates showed a 3% estimated annual increase. Thirteen per cent of the cases had @entity3 at diagnosis. In the present series, 24% of @entity4303 @entity1 had more than one @entity5 . The overall 5-year relative survival rate was 82%. In conclusion, improvements in diagnostic techniques seem to have influenced the epidemiology of @entity5 , leading to a slightly different site distribution and a better stage distribution at diagnosis. Increasing incidence and improving survival rates were shown.
