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.

Introduction and aims The role of genetic factors in the etiology and prognosis of patients with sporadic colorectal cancer is controversial. We have therefore investigated the biological and clinicopathological influence of immunohistochemical MSH2 expression in colorectal cancer. Patients and methods A total of 49 consecutive patients with unselected colorectal cancer operated on in our unit were included in the study. All tumors were resected and tumor specimens were evaluated for MSH2 expression. Clinicopathological data and patient survival were correlated with MSH2 staining. Uni- and multivariate analyses were performed. The minimum follow-up period was five years. Results Curative resection was performed in 34 patients (64.9%), 14 of whom subsequently relapsed. At the end of the overall follow-up 25 (51%) patients had died, 21 of cancer-related causes. Twenty-eight patients (57.1%) were negative for MSH2 staining. Only vascular invasion was significantly correlated with MSH2 expression (lower median values; p=0.04). The overall median survival was 47.9 months (95% CI=27–86.6%). Multivariate analysis of variables in relation to survival showed that T stage (p=0.001), N stage (p<0.001) and MSH2 expression (p=0.01) were independent factors for survival. Conclusions Reduced MSH2 expression is frequent in unselected colorectal cancer patients. Only vascular invasion was correlated with MSH2 expression in this study. Survival was related to TN stage and MSH2 staining.

Background: Fibroblast growth factor 9 (FGF9) or Glia activating factor (GAF) is categorized in the paracrine class of the FGF family, which is involved in various cancer development and progressions. Interestingly, the invasion role of FGF9 in colorectal cancer (CRC) was not clarified up to now. Objectives: In the present investigation, the lymphatic and vascular invasion characteristic of FGF9 was figured out in fresh frozen (FF) tissue samples and paired Formalin-fixed, paraffin-embedded (FFPE) tissues. Methods: The present invasion study according to FGF9 expression evaluation was performed on 80 cancerous resected fresh tissues and 40 paired paraffined block specimens parallel with 80 adjacent non-tumoral tissue samples. RNA extraction and cDNA synthesis were performed; qRT-PCR at mRNA level was applied. FGF9 expression correlation with clinical parameters was defined by the Mann-Whitney U-test. ROC curve and Kaplan-Meier analyses were designed to show the value of prognostic biomarker of FGF9. Results: Accordingly, 52% of fresh tissue samples and 51% of FFPE specimens were upregulated in comparison with corresponding normal tissues. A significant correlation was seen between FGF9 expression level and tumor stage (P < 0.0017, P < 0.03), lymph node metastasis (P < 0.001, P < 0.047), and vascular invasion (P < 0.004, P < 0.047) in fresh tissue samples and paraffined blocks, respectively. ROC was created to distinguish stage I and II from III and IV in FF and FFPE samples, respectively (P < 0.002, P < 0.031). Likewise, the AUC evaluation in both fresh and paraffined samples was similar. The overall survival was lower in 3 years of follow-up in patients with CRC with overexpression of FGF9 (P < 0.02). Conclusions: Altogether, it can be deduced that lymphatic and vascular invasion correlated with FGF9 upregulation since FGF9 can be used as an effective prognostic biomarker according to pathologic results even in paraffined block samples or FF tissue specimens in CRC.
