Abstract Background There have been controversial voices on if hepatitis B virus infection decreases the risk of colorectal liver metastases or not. This study aims to the find the association between HBV infection and postoperative survival of colorectal cancer and the risk of liver metastases in colorectal cancer patients. Methods Patients who underwent curative surgical resection for colorectal cancer between January 2011 and December 2012 were included. Patients were grouped according to anti-HBc. Differences in overall survival, time to progress, and hepatic metastasis-free survival between groups and significant predictors were analyzed. Results Three hundred twenty-seven colorectal cancer patients were comprised of 202 anti-HBc negative cases and 125 anti-HBc positive cases, and anti-HBc positive cases were further divided into high-titer anti-HBc group (39) and low-titer anti-HBc group (86). The high-titer anti-HBc group had significantly worse overall survival (5-Yr, 65.45% vs. 80.06%; P < .001), time to progress (5-Yr, 44.26% vs. 84.73%; P < .001), and hepatic metastasis-free survival (5-Yr, 82.44% vs. 94.58%; P = .029) than the low-titer group. Multivariate model showed anti-HBc ≥ 8.8 S/CO was correlated with poor overall survival (HR, 3.510; 95% CI, 1.718–7.17; P < .001), time to progress (HR, 5.747; 95% CI, 2.789–11.842; P < .001), and hepatic metastasis-free survival (HR, 3.754; 95% CI, 1.054–13.369; P = .041) in the anti-HBc positive cases. Conclusions Higher titer anti-HBc predicts a potential higher risk of liver metastases and a worse survival in anti-HBc positive colorectal cancer patients.

e15545 Background: Hepatic metastasis is the most common site of distant spread from colorectal cancer. About 15-25% patients with colorectal cancer harbors hepatic metastasis. The molecular mechanism and predicting biomarkers in colorectal cancer are still not fully understood. Methods: 57 Chinese colorectal cancer patients were enrolled in a cohort study. Samples of primary tumor were collected in these patients and underwent whole exome sequencing. Mutation profiles of primary tumors between the patients with metastasis and those without metastasis were analyzed and compared. Results: In the cohort, 54.4% (31/57) patients presented hepatic metastasis at the time of diagnosis, while 45.6% (26/57) did not. The patients were divided into 2 groups—with hepatic metastasis and without hepatic metastasis. The mutation landscape of primary tumor indicated that the Top 3 most frequently mutated genes of both groups were the same and presented mutated TP53, APC, and KRAS. 2. Interestingly, compared with the patients without hepatic metastasis, the patients with hepatic metastasis presented a higher frequency of mutated TCF7L2 (35.5% vs 3.85%) and TRIM77 (16.1% vs 0%). Moreover, in the patients with hepatic metastasis, the patients with TRIM77 mutation in primary tumor showed a worse overall survival (p < 0.0001). Conclusions: TCF7L2 and TRIM77 may be identified as potential candidate predicting biomarkers for hepatic metastasis in colorectal patients. In addition, mutated TRIM 77 predicted a poor overall survival in hepatic metastasis from colorectal cancer.

Abstract Background: B3GNT6 encodes the core 3 synthase in O-glycan biosynthesis. It is commonly expressed in the GI tract, while its clinical significance in colorectal cancer remains largely unknown.Methods: We gathered mRNA transcriptomic sequencing data from 3 Gene Expression Omnibus (GEO) datasets (GSE37182, GSE39582, GSE103512) and The Cancer Genome Atlas (TCGA) to compare the B3GNT6 mRNA level between colorectal cancer tissues and normal tissues and to evaluate its value as a prognostic marker. We further validated this in protein level using online database Human Protein Atlas and with immunohistochemical staining of B3GNT6 with our own cohort. Results: B3GNT6 expression was downregulated in colorectal cancer tissue compared with that in normal tissue in both mRNA and in protein level. Downregulation of B3GNT6 was associated with poor overall survival of colorectal cancer in GSE39582 and in TCGA database. Low B3GNT6 mRNA level was significantly associated with chromosome stable (CIN negative) and KRAS mutated group colorectal cancer patient. GSEA revealed that low B3GNT6 level in colorectal cancer is associated with upregulated proteasome activity.Conclusions: Downregulated B3GNT6 was correlated with poor overall survival of colorectal cancer patients. B3GNT6 could be used as a good prognostic marker in colorectal cancer.
