This study was conducted to evaluate the significance of preoperative serum sialic acid levels in the diagnosis and prognosis of colorectal cancer (CRC). Total sialic acid (TSA) was determined by the thiobarbituric acid method and normalized to total protein (TP). A postoperative follow-up of CRC patients classified as Dukes’ stages A, B or C was performed and survival analysis was carried out to evaluate the impact of sialic acid levels on tumor recurrence. Our diagnostic studies indicate that TSA/TP is a better marker than either TSA or carcinoembryonic antigen (CEA), especially for the detection of CRC patients at an early stage. At a cutoff of 30.90 nmol/mg of protein, TSA/TP showed a sensitivity of 85% with a specificity of 97% to discriminate CRC patients from healthy donors. In survival analysis, both TSA and TSA/TP were found to be significant prognostic factors for tumor recurrence in CRC. Furthermore, TSA/TP could distinguish patients at high risk of recurrence within Dukes’ stage B and in multivariate analysis it was identified as the best independent prognostic factor. According to our results, preoperative serum TSA/TP content could supply additional information to that provided by Dukes’ stage about the prognosis of CRC patients.

607 Background: Preoperative serum systemic inflammatory response (SIR) has been reported in patients with various cancers including colorectal cancer (CRC) as predictive biomarker of early recurrence. Molecular phenotypes of CRC including microsatellite instability (MSI) status and tumor infiltrating lymphocytes (TILs) have also known to be associated with recurrence in curative CRC patients. We comprehensively evaluated SIR status, MSI status and TILs in curative CRC patients and investigated which can be promising as high risk markers of recurrence in these patients. Methods: This retrospective study enrolled 157 CRC patients with stage I-III undergoing curative operation for whom preoperative neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR) and CRP were available as indicators of SIR status. For analysis of molecular phenotypes, we evaluated TILs by counting the number of intra-tumor Foxp3 and CD8 positive T cells by IHC analysis. Next, MSI status was determined in using 5 mononucleotide repeat microsatellite markers. Finally, we investigated the impact of SIR status, TILs and MSI status on the recurrence of these patients. Results: This study included a total of 90 males and 67 females, with an average age of 66.9 years. Twenty-nine patients (18.4%) developed recurrence. Kaplan-Meier analysis using SIR indicators revealed that patients with high CRP, NLR and PLR levels were significantly poorer disease free survival (DFS) than those with low levels. Low infiltrating CD8-positive T cells were significantly predictive factors for poor DFS, but there was no correlation between MSI status and recurrence, In univariate analysis, low infiltrating CD8-positive T cells, high CEA, CRP, NLR and PLR levels in serum were significantly predictive factors for poor DFS, respectively. Multivariate analysis showed that low infiltrating CD8-positive T cells and high serum CRP levels were independent predictive markers for recurrence in curative CRC patients. Conclusions: We demonstrated that evaluation of both CRP levels in preoperative serum and tumor infiltrating CD8 lymphocytes in CRC tissues are useful to predict the curative CRC patients with early relapse.
