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.

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.

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).

11038 Background: There are no validated biomarkers for clinical response or survival benefit in patients treated with bevacizumab (Bv) in advanced metastatic colorectal cancer (mCRC). The aim of this study was to evaluate the predictive value of putative biomarkers in mCRC. Methods: One hundred and five mCRC patients who received Bv combined with FOLFOX or FOLFIRI were retrospectively evaluated for clinical and pathological characteristics. VEGFR1, VEGFR2, VEGFR3, PlGF, DLL4 and NOTCH1 expression were assessed by immunohistochemistry on formalin-fixed, paraffin-embedded neoplastic tissue of either primary or metastatic tissue in a tissue microarray. High levels of expression were defined as less than or equal to or more than the median. Survival curves were calculated by the Kaplan-Meier method and compared by the log-rank test. For multivariate analysis the Cox proportional hazards model was used. Results: Grade 1 or 2 (p=0.01), non-mucin-producing histology (p=0.04) and presence of liver metastasis (p=0.001) were associated with a higher response rate. There was no difference between the expression of markers and the response rate. ECOG 0 or 1 (p=0.002), grade 1 or 2 (p=0.02), liver metastasis (p=0.003), no lymph node metastasis (p=0.01) no peritoneal metastasis (p=0.02) and resection of metastasis (p<0.001) were correlated with higher progression-free survival (PFS). There was also a strong correlation between ECOG 0 or 1 (p=0.001), grade 1 or 2 (p=0.006), no lymph node metastasis (p=0.004), liver metastasis (p<0.001) and resection of metastasis (p<0.0001) with better overall survival. There was a trend between high expression of NOTCH1 (p=0.06) and worst PFS.High expression of VEGFR2 (p=0.07) was slightly associated with a better overall survival, while high expression of NOTCH1 was associated with a worse overall survival (p=0.01). Using multivariate analysis, NOTCH1 proved to be an independent variable for adverse overall survival (HR 2.01, IC 1.07 – 3.77, p=0.02). Conclusions: High NOTCH1 expression assessed by immunohistochemistry is capable of predicting poor survival in advanced colorectal cancer patients treated with bevacizumab.

This study aimed at building a prognostic signature based on a candidate gene panel whose expression may be associated with lymph node metastasis (LNM), thus potentially able to predict colorectal cancer (CRC) progression and patient survival. The mRNA expression levels of 20 candidate genes were evaluated by RT-qPCR in cancer and normal mucosa formalin-fixed paraffin-embedded (FFPE) tissues of CRC patients. Receiver operating characteristic curves were used to evaluate the prognosis performance of our model by calculating the area under the curve (AUC) values corresponding to stage and metastasis. A total of 100 FFPE primary tumor tissues from stage I–IV CRC patients were collected and analyzed. Among the 20 candidate genes we studied, only the expression levels of VANGL1 significantly varied between patients with and without LNMs (p = 0.02). Additionally, the AUC value of the 20-gene panel was found to have the highest predictive performance (i.e., AUC = 79.84%) for LNMs compared with that of two subpanels including 5 and 10 genes. According to our results, VANGL1 gene expression levels are able to estimate LNMs in different stages of CRC. After a proper validation in a wider case series, the evaluation of VANGL1 gene expression and that of the 20-gene panel signature could help in the future in the prediction of CRC progression.
