XXXX in Stockholm County--a study of epidemiology, prognosis, mortality and @entity5 risk with special reference to a surveillance program.

The epidemiology of @entity31 ( @entity31 ) in Stockholm County 1955-79 was investigated. There were 1274 cases. The proportion of @entity1 with @entity4272 , left-sided and total extent of disease remained constant over the study period. The incidence increased over the first 20 years followed by a plateau. The peak incidence in relation to age increased slightly but remained in the third and fourth decade through the study period. The incidence in @entity1 over 40 years of age increased markedly towards the end of the study. There were 109 deaths at follow-up (Dec. 1981) among those having the @entity31 diagnosis between 1955-1979. Twentysix out of 41 @entity1 who died due to @entity31 did so postoperatively. The mortality pattern among those 68 @entity1 who had causes of death unrelated to @entity31 was similar to the expected. There was a decrease in cumulative survival probability compared with the expected, in particular in those with @entity1960 . This was also seen when only deaths unrelated to @entity31 were included suggesting an increased sensitivity to the ordinary disease spectrum in @entity31 @entity1 . Between 1945-1979 there were 1339 @entity1 who had @entity31 diagnosed. Twentyfive of those had developed @entity694 (24 with @entity1960 ) at follow-up (Dec. 1981). Eighteen were dead at follow-up, the survival time being in direct relation to the Dukes' grading at @entity5 diagnosis irrespective of age. The cumulative @entity5 risk at 25 years duration ( @entity1960 @entity1 only) was 13% (SD 4%) compared to the expected 1,9%. In a selected group of 71 @entity1 followed for @entity5 surveillance during the period 1974-82 nine @entity1 developed at least low grade @entity1141 including one @entity189 . The @entity1141 or @entity5 leading to operation was found above the rectum in four of five operated @entity1 , all having @entity1960 with a duration ranging between 25-44 years.
