They included 231 patients with LNM(49.3%) and 238 patients without LNM. Follow-up for these patients was taken through to December 31, 2012.RESULTS: The baseline serum direct bilirubin concentration was(median/inter-quartile range) 2.30/1.60-3.42 μmol/L. Univariate analysis showed that compared with patients without LNM, the patients with LNM had an increased level of direct bilirubin(2.50/1.70-3.42 vs 2.10/1.40-3.42, P = 0.025). Multivariate analysis showed that direct bilirubin wasindependently associated with LNM(OR = 1.602; 95%CI: 1.098-2.338, P = 0.015). Moreover, we found that:(1) serum direct bilirubin differs between male and female patients; a higher concentration was associated with poor tumor classification;(2) as the baseline serum direct bilirubin concentration increased, the percentage of patients with LNM increased; and(3) serum direct bilirubin was associated with the prognosis of rectal cancer patients and higher values indicated poor prognosis.CONCLUSION: Higher serum direct bilirubin concentration was associated with the increased risk of LNM and poor prognosis in our rectal cancers.展开更多
