Survival differences between European and US patients with colorectal cancer: role of stage at diagnosis and surgery
Background: Population based colorectal cancer survival among patients diagnosed in 1985–89 was lower in Europe than in the USA (45% v 59% five year relative survival). Aims: To explain this difference in survival using a new analytic approach for patients diagnosed between 1990 and 1991. Subjects: A total of 2492 European and 11 191 US colorectal adenocarcinoma patients registered by 10 European and nine US cancer registries. Methods: We obtained clinical information on disease stage, number of lymph nodes examined, and surgical treatment. We analysed three year relative survival, calculating relative excess risks of death (RERs, referent category US patients) adjusted for age, sex, site, …
Understanding variations in survival for colorectal cancer in Europe: a EUROCARE high resolution study
BACKGROUND—Marked differences in population based survival across Europe were found for colorectal cancers diagnosed in 1985-1989. AIMS—To understand the reasons for these differences in survival in a new analysis of colorectal cancers diagnosed between 1988 and 1991. SUBJECTS—A total of 2720 patients with adenocarcinoma of the large bowel from 11 European cancer registries (CRs). METHODS—We obtained information on stage at diagnosis, diagnostic determinants, and surgical treatment (not routinely collected by CRs) and analysed the data in relation to three year observed survival, calculating relative risks (RRs) of death and adjusting for age, sex, site, stage, and determinants of stage.
