570 Background: The significance of vascular emboli (VE) in stage III colorectal cancer (CRC), the mechanism of their formation and their therapy strategy remain obscure demanding enhanced research. Methods: Data from 323 consecutive patients (192 non-VE, 131 VE) receiving radical surgery and adjuvant chemotherapy in our institution between Jan. 2009 and Nov. 2014 were retrospectively collected. The follow-up deadline was Feb. 2016. Potential prognostic risk factors were tested using univariate and multivariate survival analyses. mRNAs differentially expressed between VE and non-VE stage III CRC were analyzed using Agilent Gene Expression oligo-microarrays (Version 6.5). Patient-derived xenograft (PDX) nude mouse models were constructed to evaluate the efficacy of adjuvant chemotherapy plus targeted drugs (cetuximab or bevacizumab) on VE and non-VE stage III CRC. Results: VE was significantly associated with gross tumor morphology (p = 0.001), histologic type (p < 0.001), lymph node status (p < 0.001), sub-class of stage III (p =0.001), and serum CA199 level (p = 0.022). VE and lymph node status were independent risk factors for overall survival (OS) (p < 0.001, p = 0.008) and disease-free survival (DFS) (p < 0.001, p = 0.007). The median OS and DFS in VE stage III CRC patients were 38 months and 24 months, respectively. Compared with pericarcinous tissue, 809 genes (396 up-, 413 down-regulated) were differently expressed in no-VE tissue, and 1513 genes (898 up-, 615 down-regulated) in VE tissue. The top ten up-regulated protein-coding genes in VE stage III CRC were ITGBL1 (p<0.001), PROCR (p<0.001), CENPW (p<0.001), ZNF485 (p<0.001), VEGFA (p<0.001), DSG3 (p<0.001), CYP24A1 (p=0.001), COL10A1 (p=0.001), HIST3H2A (p=0.001)and PSAT1 (p=0.002). Conclusions: VE appears to be an independent risk factor for the prognosis of stage III CRC patients treated with radical surgery and adjuvant chemotherapy. Differently regulated genes seem to be involved in the formation and progress of VE. The therapy scheme should be more individualized taking into account the VE status.

Node Status

483 Background: Currently, techniques that determine lymph node positivity (prior to resection) have poor sensitivity and specificity. The ability to determine lymph node status, based on preoperative biopsies, would greatly assist in planning treatment in colorectal cancer. This is particularly relevant in polyp-detected cancers. This study aims to harness the potential of public gene expression repositories, to develop gene expression profiles that could accurately determine nodal status in colorectal cancer. Methods: Public gene expression repositories were screened for experiments comparing metastatic and non-metastatic colorectal cancer. A customized graphic user interface was developed to extract genes dysregulated across the majority of identified studies (i.e., consensus profiles or “CP”). The utility of CP was tested by determining if classifiers could be derived that determined nodal positivity or negativity. CP-derived classifiers were tested on separate Affymetrix and Illumina–based experiments and collated outputs compiled in summary-receiver operator curve characteristic format. The association between classification and oncologic outcome was determined using an additional, independent data set. Results: Four consensus profiles were generated from which classifiers were derived that accurately determined node positive and negative status (pooled AUC were 0.79 ± 0.04 and 0.8 ± 0.03 for nodal positivity and negativity respectively). Overall AUC ranged from 0.73 to 0.86 demonstrating high accuracy across consensus profile type, classification technique and array platform used. As CP enabled classification of nodal status, survival outcomes could be compared for those predicted node negative or positive. Patterns of disease-free and overall survival were identical to those observed for standard histopathologic nodal status. Genes contained within consensus profiles were strongly linked to the metastatic process and included FYN, WNT5A, COL8A1 and BMP. Conclusions: Microarray expression data available in public gene expression repositories can be harnessed to generate consensus profiles. The latter are a source of classifiers that have prognostic and predictive properties.

Tnm Staging System

516 Background: We proposed T-plus staging system which abandon the criterion to discriminate stage II/III by lymph node status and strengthens weighting of the T stage according to cluster analysis of the summary survival data of SEER. In this study, this principle of the T-plus staging system was verified with single center data by nomogram analysis. Methods: The 1,099 patients with colorectal cancer diagnosed before 2005 were analyzed to build a novel staging system based on nomogram (nomo-staging system). The remaining 981 patients diagnosed after 2005 were used to test the performance of nomo-staging system, T-plus staging system and the 7th edition TNM staging system by Akaike information criteria (AIC), Harrell’s c-index and the area under the curve (AUC) of Receiver Operating Characteristic to predict 5-year overall survival. A smaller AIC, higher c-index and higher AUC indicated a better staging system. Results: The nomo-staging system and T-plus staging system were listed in Table 1. The validation found that the 7th edition TNM staging system showed the weakest performance. For AIC, both nomo-staging system and T-plus staging system showed smaller value than the 7th edition TNM staging system (3214.912 vs. 3224.643 vs. 3229.810). For Harrell’s c-index, both the T-plus staging system and nomo-staging system showed higher value than the 7th edition TNM staging system (0.6814 vs. 0.6787 vs. 0.6778). For AUC to predict 5-year OS, the T-plus staging system and nomo-staging system showed slightly higher value than the 7th edition TNM staging system (0.6944 vs. 0.6924 vs. 0.6913). Conclusions: We propose replacement of lymph node status as the criterion to discriminate colorectal cancer stage II/III with greater weighting of the T stage. [Table: see text]
