Targets and elective colorectal cancer: outcome and symptom delay at surgical resection.
OBJECTIVE
To determine, for elective patients with colorectal cancer, if associations exist between the length of symptom history at surgical resection and Dukes stage, completeness of the surgical procedure and patient survival.


METHODS
A prospective cohort study was undertaken. Five hundred and eighty-two patients with colorectal cancer, admitted for surgical resection after outpatient consultation, divided into four equal quartiles according to length of symptom history (short: n = 131, 0-103 days; medium: n = 136, 104-177 days; long: n = 136, 178-318 days; very long: n = 137, 319-1997 days). The main outcome measures used were the Extent of tumour (Dukes stage) at resection, completeness of resectional surgery (curative vs palliative), patient survival after resection.


RESULTS
For patients undergoing elective surgical resection of colorectal cancer we did not find an association between Dukes stage and duration of patient history (Dukes stage C tumours were seen in 37% (CI: 26.2%-48.0%) of patients with a short symptomatic history as opposed to 34% (CI: 32%-62%) with a very long symptomatic history). Elective curative resection was not associated with a significantly different symptom duration than elective palliative resection (Palliative resections were performed in 24% (CI: 11.7%-36.4%) of patients with a short symptomatic history as opposed to 16% (CI: 2.4%-29.9%) with a very long symptomatic history). The median survival time for the four elective colorectal patient groups defined by length of symptomatic history was not significantly different - (short: n = 131, 4.3 years; medium: n = 136, 5.9 years; long: n = 136, 7.1 years; very long: n = 137, 5.0 years).


CONCLUSIONS
Tumour extent, completeness of resection and patient outcome after elective colorectal cancer resection was not found to have an association with length of patient history at the time of surgery.
