Time trends in mortality from small intestinal cancer have not been studied for the 1990s.
Dr Shack and colleagues from England examined secular trends in incidence, and survival from small intestinal cancer in England, Wales, and Scotland from 1975 to 2002.
The research team also considered histological type, subsite, and indices of social deprivation.
The team extracted data from the Scottish Cancer Registry database and the General Register Office for Scotland.
The researchers also obtained data from the National Cancer Intelligence Centre at the Office for National Statistics for England and Wales.

The researchers discovered that incidence rates for small intestinal cancer increased for both England, Wales, and Scotland over the study period.
They were highest among older individuals and generally greater for males than for females.
Despite the increase in incidence rates, mortality rates from small intestinal tumors tended to remain stable over the study period.
The team noted the general trend was towards increasing survival.
Indices of social deprivation were not obviously related to the incidence of small intestinal cancer, and did not influence survival.
Dr Shack's team concluded, “Incidence rates for small intestinal cancer for both England and Wales and Scotland increased in the last quarter of the 20th century.”
“But survival rates improved and mortality rates declined.”
