Objective. Саrbohydrаte antigen 19-9 (CA 19-9) is the frequently used tumor marker in the clinical setting of colorectal cancer (CRC). This study was designed to investigate the correlation between preoperative serum levels of CA 19-9 (pre-CA 19-9) and the clinicopathologic factors of patients with CRC. Patients and methods. A study was performed on 482 patients with histologically diagnosed colorectal adenocarcinoma between January 2016 and December 2017, based on retrospective collected data. The clinical data such as age, sex, size of tumor, differentiation (G), depth of tumor (T), lymph node metastasis (N), distant metastasis (M), lymphatic invasion, venous invasion, perineural invasion, stage, and preoperative serum levels of CEA (pre-CEA) and pre-CA 19-9 were obtained. These patients were classified into two groups according to pre-CA 19-9 (CA 19-9 high: H37 U/mL; CA 19-9 normal: H37 U/mL). Results. Eighty five patients among 483 patients (17.6%) with CRC showed a high pre-CA 19-9. The elevationof pre-CA 19-9 was significantly associated with size of tumor > 4.5 cm (р=0.0001), higt CEA > 5ng/ml (р<0.0001), wrong differenciation of tumor (р=0.0003), depth of tumor (р<0.0001), lymph node metastasis (р<0.0001), distant metastasis (р<0.0001), lymphatic invasion (р=0.0013), vascular invasion (р<0.0001), perineural invasion (р<0.0001), stage (р<0.0001). On multivariate analysis, high pre-CA 19-9 was shown to be independently associated with depth of tumor (р=0.05), lymph node metastasis (р=0.0006). Spearman>s correlation coefficient r between REA and CA 19-9 was 0.21 (95% CI 0.13 - 0.30; p<0.0001). Conclusion. High pre-CA 19-9 in advanced colorectal cancer might provide important information to predict the depth of tumor, lymph node metastasis.

Background and Aims. Various risk factors for lymph node metastasis (LNM) have been reported in colorectal T1 cancers. However, the factors available are insufficient for predicting LNM. We therefore investigated the utility of the new histological factor “pure well-differentiated adenocarcinoma” (PWDA) as a safe factor for predicting LNM in T1 and T2 cancers. Materials and Methods. We reviewed 115 T2 cancers and 202 T1 cancers in patients who underwent surgical resection in our center. We investigated the rates of LNM among various clinicopathological factors, including PWDA. PWDA was defined as a lesion comprising only well-differentiated adenocarcinoma. The consistency of the diagnosis of PWDA was evaluated among two pathologists. In addition, 72 T1 cancers with LNM from 8 related hospitals over 10 years (2008–2017) were also analyzed. Results. The rates of LNM and PWDA were 23.5% and 20.0%, respectively, in T2 cancers. Significant differences were noted between patients with and without LNM regarding lymphatic invasion (81.5% vs. 36.4%, p<0.001), poor histology (51.9% vs. 19.3%, p=0.008), and PWDA (3.7% vs. 25.0%, p=0.015). The rates of LNM and PWDA were 8.4% and 36.1%, respectively, in T1 cancers. Regarding the 73 PWDA cases and 129 non-PWDA cases, the rates of LNM were 0.0% and 13.2%, respectively (p<0.001). Among the 97 cases with lymphatic or venous invasion, the rates of LNM in 29 PWDA cases and 68 non-PWDA were 0% and 14.7%, respectively (p=0.029). The agreement of the two pathologists for the diagnosis of PWDA was acceptable (kappa value > 0.5). A multicenter review showed no cases of PWDA among 72 T1 cancers with LNM. Conclusions. PWDA is considered to be a safe factor for LNM in T1 cancer.

Abstract Background Gallbladder carcinoma (GBC) was the most common malignancy of biliary tract. Patients with malignancies frequently present with activated coagulation pathways, which might potentially related to tumor progression and prognosis. The purpose of the study was to investigate the clinical significance of preoperative serum fibrinogen levels and platelet counts in GBC patients. Methods The preoperative fasting serum fibrinogen levels and platelet counts of 58 patients with GBC were measured by AUV2700 automatic biochemical analyzer, as well as 60 patients with cholesterol polyps and 60 healthy volunteers. Kaplan–Meier survival analysis was applied to show the correction between fibrinogen levels and outcome after surgery. Results The fibrinogen levels of patients with GBC were significantly higher than healthy gallbladder and cholesterol polyp of gallbladder (p < 0.001 and p < 0.001, respectively). In GBC, fibrinogen levels were associated with tumor depth (p = 0.001), lymph node metastasis (p = 0.002), distant metastasis (p < 0.001) and Tumor Node Metastasis (TNM) stage (p < 0.001). The levels in TNM stage IV disease were significantly higher than stage III or stage I + II disease (p = 0.048 and p < 0.001, respectively), and in TNM stage III disease were significantly higher than stage I + II disease (p = 0.002). Furthermore, the overall survival was better in low fibrinogen level group than in high fibrinogen level group (p < 0.001). However, thrombocytosis was not significantly associated with overall survivals (p > 0.05) in multivariate analysis. Conclusions The preoperative serum fibrinogen levels and platelet counts might be reliable biomarkers for the occurance of disease, tumor depth, lymph node metastasis, distant metastasis and advanced TNM stage in patients with GBC. The serum fibrinogen levels might be a prognostic factor to predict outcome for GBC patients suffering from surgery treatment. Anticoagulation therapy might be considered to control cancer progression in future studies.

AbstractObjectiveTo investigate the expression of Hepcidin and Neogenin in tissue from patients with colorectal cancer, to evaluate the relationship between Hepcidin and Neogenin with clinical features, and to study their relationship with anemia.MethodsImmuno- histochemical method was used to detect the expression of Hepcidin and Neogenin in 62 cases of colorectal cancer. At the same time, the relationship between them and their relationship with clinical characteristics and anemia were analyzed.ResultsThe expression of Hepcidin was related to T stage (P<0.05), but not with age, gender, lymph node metastasis and distant metastasis. The expression of Neogenin was not correlated with T stage and lymph node metastasis, age, gender, and distant metastasis (P>0.05). There was no significant difference in the expression of Hepcidin and Neogenin between anemia group and non-anemia group. There was no correlation between Hepcidin and Neogenin (r =-0.04, P>0.05).ConclusionThe expression of Hepcidin in colorectal cancer was related to the T stage, and had no correlation with Neogenin. The expression of Neogenin could not be used as an objective index to reflect the biological behavior of colorectal cancer.

Abstract BackgroundPrevious studies have shown that transmembrane protease serine 3 (TMPRSS3) is abnormally expressed in various tumours and its expression is closely related to tumorigenesis and progression [1-3]. However, there have been no reports regarding the role of TMPRSS3 in colorectal cancer (CRC). The aim of the current study was to comprehensively explore the clinical value of TMPRSS3 on the radioresistance of CRC.MethodsIn this study, we evaluated the expression level of TMPRSS3 in radioresistant CRC tissues as well as CRC tissues by analysing public data sets from the Cancer Genome Atlas (TCGA), Gene Expression Omnibus (GEO), ArrayExpress, and GTEx databases, as well as explored the relationship between TMPRSS3 and lymph node metastasis, distant metastasis, and prognosis. In addition, we investigated the biological function of TMPRSS3 by gene ontology (GO) and analysis of the Kyoto Encyclopaedia of Genes and Genomes (KEGG). Finally, we created a protein-protein interaction (PPI) network to identify hub genes that may function in concert with TMMPRSS3.ResultsEight radiation-processed CRC tissue data sets and 26 CRC mRNA data sets were obtained. The pooled analysis revealed that TMPRSS3 was significantly highly expressed in CRC radioresistant tissues—SMD = 0.38 (95% CI: 0.14~0.63; p-value < 0.05). In addition, TMPRSS3 is also as highly expressed in CRC tissues—SMD = 1.55 (95% CI: 1.20~1.90; p-value < 0.05). Subsequently, we explored the relationship between TMPRSS3 and both metastasis and prognosis. The results revealed no relationship between TMPRSS3 and lymph node metastasis and distant metastasis (p-value > 0.05). Furthermore, pooled analysis of HR revealed that TMPRSS3 could be used as a risk factor for DFS—SMD = 1.28 (95% CI: 1.03~1.60; p-value < 0.05). Finally, we obtained 429 co-expressed genes for bioinformatics analysis and selected a total of four hub genes: MSLN, MFI2, CKAP4, and PXN. The results revealed that these genes cooperate with TMPRSS3 to participate in biological processes, such as CRC development, metastasis, and radioresistance by affecting autophagy, cell-cell adhesion, and extracellular matrix breakdown.ConclusionThis study reveals that TMPRSS3 has potential as a new biomarker and radioresistant therapeutic target for CRC and also has a few implications for the prognosis of CRC patients. However, this conclusion must be further experimentally verified.

Abstract Purpose Although some studies have reported differences in clinicopathological features between left- and right-sided advanced colorectal cancer (CRC), there are few reports regarding early-stage disease. In this study, we aimed to compare the clinicopathological features of left- and right-sided T1 CRC. Methods Subjects were 1142 cases with T1 CRC undergoing surgical or endoscopic resection between 2001 and 2018 at Showa University Northern Yokohama Hospital. Of these, 776 cases were left-sided (descending colon to rectum) and 366 cases were right-sided (cecum to transverse colon). We compared clinical (patients age, sex, tumor size, morphology, initial treatment) and pathological features (invasion depth, histological grade, lymphatic invasion, vascular invasion, tumor budding) including lymph node metastasis (LNM). Results Left-sided T1 CRC showed significantly higher rates of LNM (left-sided 12.0% vs. right-sided 5.4%, P < 0.05) and lymphatic invasion (left-sided 32.7% vs. right-sided 23.2%, P < 0.05). Especially, the sigmoid colon and rectum showed higher rates of LNM (12.4% and 12.1%, respectively) than other locations. Patients with left-sided T1 CRC were younger than those with right-sided T1 CRC (64.9 years ±11.5 years vs. 68.7 ± 11.6 years, P < 0.05), as well as significantly lower rates of poorly differentiated carcinoma/mucinous carcinoma than right-sided T1 CRC (11.6% vs. 16.1%, P < 0.05). Conclusion Left-sided T1 CRC, especially in the sigmoid colon and rectum, exhibited higher rates of LNM than right-sided T1 CRC, followed by higher rates of lymphatic invasion. These results suggest that tumor location should be considered in decisions regarding additional surgery after endoscopic resection. Trial registration This study was registered with the University Hospital Medical Network Clinical Trials Registry (UMIN 000032733).

Clinicopathological Significance

Introduction The aim of this study was to elucidate the clinicopathological significance of HER2 expression and the diagnostic accuracy of HER2 immunohistochemistry (IHC) in colorectal cancer (CRC). A total of 2,573 CRC cases from 13 eligible studies were included. Methods We performed a meta-analysis to examine the correlations between HER2 expression and clinicopathological characteristics in CRC. Concordance analysis between HER2 IHC and in situ hybridization (ISH) and diagnostic test accuracy review was conducted. Results The estimated rate of HER2 IHC overexpression was 0.162 (95% confidence interval [CI] 0.106-0.240). HER2 IHC overexpression was significantly correlated with lymph node metastasis and distant metastasis but not tumor depth. HER2 IHC overexpression was not correlated with overall survival. The concordance rates between IHC and ISH were 0.968 (95% CI 0.881-0.992), 0.377 (95% CI 0.225-0.557) and 0.780 (95% CI 0.390-0.952) for HER2 IHC scores of 0/1+, 2+ and 3+, respectively. The diagnostic test accuracy review of HER2 IHC revealed that the pooled sensitivity and specificity were 0.71 (95% CI 0.58-0.82) and 0.96 (95% CI 0.94-0.97), respectively. The diagnostic odds ratio and area under the summary receiver operating characteristic curve were 51.34 (95% CI 3.82-690.54) and 0.9704, respectively. Conclusions HER2 IHC overexpression was significantly correlated with lymph node metastasis and distant metastasis. CRC cases with HER2 IHC scores of 0/1+ exhibited good agreement with the ISH data. However, additional ISH analysis is needed to confirm HER2 status in cases with IHC scores of 2+ or 3+.

Synchronous Distant Metastasis

Abstract It is rare and understudied for patients with stage T1 colorectal cancer to have synchronous distant metastasis. This study was to determine the clinicopathological factors associated with distant metastasis and prognosis. T1 colorectal cancer patients diagnosed between 2010 and 2015 were obtained from the SEER database. Logistic regression was applied to determine risk factors related to distant metastasis. Cox-proportional hazard models were used to identify the prognostic factors for patients with distant metastasis. Among 21,321 patients identified, 359 (1.8%) had synchronous distant metastasis and 1807 (8.5%) had lymph node metastasis. Multivariate analysis revealed that younger age, positive serum CEA, larger tumor size, positive tumor deposit, perineural invasion, lymph node metastasis, histology of non-adenocarcinoma and poorer differentiation were significantly associated with the increased risk of synchronous distant metastasis. Older age, female, African American, positive CEA, positive lymph node metastasis, positive tumor deposit, larger tumor size, no chemotherapy, inadequate lymph node harvesting and no metastasectomy were correlated with worse survival in these patients with synchronous distant metastasis. Patients with metastasis to the liver displayed the highest rate of positive CEA. We conclude that T1 colorectal cancer patients with multiple risk factors need thorough examinations to exclude synchronous distant metastasis. Chemotherapy, adequate lymph node cleaning and metastasectomy are associated with improved survival for those patients with distant metastases. Positive serum CEA may be useful in predicting distant metastases in patients at stage T1.
