Abstract The frequency and significance of hepatic lymph node (HLN) metastasis were retrospectively evaluated in 43 patients with unresectable synchronous liver metastasis of colorectal cancer who underwent resection of the primary tumor and histopathologic evaluation of HLNs between March 1997 and August 2007. HLN metastasis was detected in 12 patients (27.9%). No significant correlations were observed between the presence of HLN metastasis and any of the 12 clinicopathologic factors examined. On multivariate analysis using the Cox proportional hazards model, the presence of HLN metastasis (P  =  0.002), along with a large number (≥4) of regional lymph node metastases (P  =  0.003), and nonuse of oxaliplatin-based chemotherapy (P  =  0.005) were identified as independent risk factors for shorter survival. To establish a new therapeutic strategy for initially unresectable liver metastasis of colorectal cancer, HLNs should be examined histologically in patients undergoing resection of hepatic lesions when they are rendered resectable by effective chemotherapy.

Abstract Background Colorectal cancer (CRC) is the fourth most common cancer in men and the third most common cancer in women worldwide. The incidence and mortality of CRC was increasing rapidly in China. Lymph node-negative colorectal cancer patients with synchronous liver metastasis (LNLM1) was defined as “skip” lymph vascular invasion on hepatic metastasis, who presenting poor prognosis. We aiming to investigate the potential mechanism for the “skip” lymph vascular invasion on hepatic metastasis in colorectal cancer. Methods The microarray was applied for screening the transcription landscape of circRNA in lymph node negative CRC patients with synchronous liver metastasis (LNLM1) or without liver metastasis (LNLM0). The gain- and loss-of-function experiments was conducted in CRC cell lines and animal models. The RNA pull-down, RNA immunoprecipitation n was further employed in exploring the detailed mechanism of circRNA and associated target genes. Results We identified the aberrant increased circRNA circ_0124554 (also entitled as circ-LNLM) in tumor tissues of LNLM1 patients comparing with either the tumor tissues of LNLM0 or adjacent tissues of LNLM1. Circ-LNLM1 expression was highly corrected with liver metastasis and vascular invasion. Ectopic expression of cytoplasmic located circ-LNLM could promote invasion of CRC cells and induced the liver metastasis in animal models through the direct binding with AKT. The phosphorylation of AKT (T308/S473) was activated due to the blocked ubiquitination site of Lys in 0-52aa peptide of circ-LNLM. Endogenous plasma expression of circ-LNLM induced poor prognosis of LNLM1 and could distinguish LNLM1 patients from LNLM0. Conclusions The circ-LNLM blocked the ubiquitination of AKT could promote the early metastasis especially for the lymph node-negative colorectal cancer patients with synchronous liver metastasis. The circ-LNLM might be prognosis and diagnosis biomarker for LNLM1 patients.

e15111 Background: The incidence of colorectal cancer (CRC) in Peru has increased in the last decades. Needing to use all the possible tools for an accurate diagnosis and early treatment. Neutrophil-to-lymphocyte ratio (NLR) has been associated as poor prognostic factor in OS and PFS in CRC. There is no data that support this statement in Latin America. It is of a special utility in our country the detection of a simple and reproducible prognostic biomarker that guides the use of more advanced tests. Our objective was to explore the factors associated with OS in the local-locally advanced and metastatic settings. Methods: We retrospectively reviewed the electronic medical records of 609 patients with CRC from one specialized Peruvian cancer center between 2006 and 2016 Descriptive results for numeric variables were presented as means with standard deviation (SD) or medians with interquartile range (IQR), depending on their distributions; otherwise, we expressed the qualitative variables as numbers with percentages. We divided our population into two groups: Local-locally advanced (L-LA) (516 pts) and debut metastatic- recurrence (M-R) (108 pts). We performed a ROC curve analysis to determine an appropriate cut-off value for NLR in both groups (L-LA:NLR ≥3, M-R:NLR ≥5). A univariate survival analysis was performed with Kaplan Meier method, comparing the curves with Log Rank test. A multivariate analysis was performed using the Cox regression model with the statistically significant variables found in the univariate analysis. Results: Pts with high NLR had significantly shorter OS in L-LA [HR, 12.1; 95% CI,5.019-29.211; p < 0.001] M-R [HR, 5.382; 95% CI,2.835-10.217; p < 0.001] than pts with low NLR. In the multivariate model, NLR retained a significant association with OS in both groups. Cox regression demonstrated that in L-LA setting sex, histologic grade and lymph node involvement; and in M-R setting sidedness, histologic grade, LVI and metastasectomy performed were independently risk factors for a shorter OS. Conclusions: High NLR is associated with poor prognosis (with our cut-offs L-LA:NLR ≥3, M-R:NLR ≥5). There are other variables to be considered that affect the OS, as: sex, histologic grade and lymph node involvement, sidedness, histologic grade, LVI and metastasectomy performed.
