Abstract
Background Lymph node involvement significantly impacts the survival of gastric cancer patients and is a crucial factor in determining the appropriate treatment. This study aimed to evaluate the potential of enhanced computed tomography (CT)-based radiomics in predicting lymph node metastasis (LNM) and survival in patients with gastric cancer before surgery. Methods Retrospective analysis of clinical data from 192 patients diagnosed with gastric carcinoma was conducted. The patients were randomly divided into a training cohort (n = 128) and a validation cohort (n = 64). Radiomic features of CT images were extracted using the Pyradiomics software platform, and distinctive features were further selected using a Lasso Cox regression model. Features significantly associated with LNM were identified through univariate and multivariate analyses and combined with radiomic scores to create a nomogram model for predicting lymph node involvement before surgery. The predictive performance of radiomics features, CT-reported lymph node status, and the nomogram model for LNM were compared in the training and validation cohorts by plotting receiver operating characteristic (ROC) curves. High-risk and low-risk groups were identified in both cohorts based on the cut-off value of 0.582 within the radiomics evaluation scheme, and survival rates were compared. Results Seven radiomic features were identified and selected, and patients were stratified into high-risk and low-risk groups using a 0.582 cut-off radiomics score. Univariate and multivariate analyses revealed that radiomics features, diabetes mellitus, Nutrition Risk Screening (NRS) 2002 score, and CT-reported lymph node status were significant predictors of LNM in patients with gastric cancer. A predictive nomogram model was developed by combining these predictors with the radiomics score, which accurately predicted LNM in gastric cancer patients before surgery and outperformed other models in terms of accuracy and sensitivity. The AUC values for the training and validation cohorts were 0.82 and 0.722, respectively. The high-risk and low-risk groups in both the training and validation cohorts showed significant differences in survival rates. Conclusion The radiomics nomogram, based on contrast-enhanced computed tomography (CECT ), is a promising non-invasive tool for preoperatively predicting LNM in gastric cancer patients and postoperative survival.

Abstract
Cancer is one of the major causes of mortality worldwide. Regional lymph node metastasis is an important mechanism during the spread of human cancers, in which transcription regulation plays an essential role. This study formulated a regression-model-based quantitative transcription regulation (mqTrans) between one mRNA gene and multiple transcription factors (TFs). Computational pan-cancer screening was carried out to detect the quantitative dysregulation of transcription regulation in the regional lymph node metastasis of 18 cancer types. Only a few metastasis-dysregulated mqTrans models were shared among the cancer types. The mRNA genes of the metastasis-dysregulated mqTrans models were not differentially expressed in regional lymph node metastasis. The experimental data suggested that mqTrans technology provided a complementary approach to the evaluation of transcription regulation mechanisms and may facilitate its quantitative investigation in other phenotypes.

Abstract
OBJECTIVES To investigate the prognosis value of lymphatic vessel invasion (LVI) in pN0 gastric cancer patients with insufficient examined lymph nodes (ELNs). METHODS Clinicopathologic and prognostic data of pN0 gastric cancer patients with insufficient ELNs who underwent radical surgery in our institution were retrospectively studied. RESULTS Firstly, we confirmed that less than 16 but not less than 30 ELNs were insufficient ELNs in the present study. Of the 350 pN0 patients with < 16 ELNs, 64 patients (18.29%) had LVI. The overall survival (OS) of patients with LVI was significantly poorer than those without LVI. Multivariate analysis suggested that LVI was one of the independent factors predicting prognosis of pN0 patients with < 16 ELNs. Further analyses suggested that there were similar prognoses between pN0 patients with < 16 ELNs who had LVI and pN1 patients, and between pN0 patients with < 16 ELNs who had no LVI and pN0 patients with ≥ 16 ELNs, respectively. Therefore, we proposed a novel pN classification, in which LVI-positive pN0 gastric cancer with < 16 ELNs was classified as pN1 disease. Two-step multivariate analysis demonstrated that the novel pN classification was more suitable for prognostic assessment than the original one. CONCLUSIONS LVI is a powerful and independent prognostic factor for pN0 gastric cancer patients with < 16 ELNs, and node-negative gastric cancer with < 16 ELNs which had LVI should be considered as node-positive disease. LVI is an effective indicator identifying patients stage migration happens to in pN0 patients with < 16 ELNs.

Abstract
Accurate prediction of lymph node (LN) status is crucially important for appropriate treatment planning in patients with early gastric cancer (EGC). However, consensus on patient and tumor characteristics associated with LN metastasis are yet to be reached. Through systematic search, we identified several independent variables associated with LN metastasis in EGC, which should be included in future research to assess which of these variables remain as significant predictors of LN metastasis. On the other hand, even if we use these promising parameters, we should realize the limitation and the difficulty of predicting LN metastasis accurately. The sentinel LN (SLN) is defined as first possible site to receive cancer cells along the route of lymphatic drainage from the primary tumor. The absence of metastasis in SLN is believed to correlate with the absence of metastasis in downstream LNs. In this review, we have attempted to focus on several independent parameters which have close relationship between tumor and LN metastasis in EGC. In addition, we evaluated the history of sentinel node navigation surgery and the usefulness for EGC.

Abstract
OBJECTIVE Lymph node (LN) metastasis is widely accepted as a poor prognosis indicator in patients with gastric cancer. An accurate preoperative prediction of LN status is of crucial importance for the planning treatment. The aim of the present study was to assess the predictive value of the preoperative platelet/lymphocyte (PLR) and neutrophil/lymphocyte rates (NLR) on the LN metastasis in gastric cancer patients and to develop a new preoperative score system to predict LN metastasis. PATIENTS AND METHODS A total of 492 operable patients with gastric cancer were enrolled in our study. The clinical utility of the PLR and NLR was evaluated by receiver operating characteristic (ROC) curves. The logistic analysis was used to identify the independent parameters associated with LN metastasis. Then, a score system including those independent parameters that can be detected preoperatively was established, which was also tested by an ROC curve. RESULTS The ideal cutoff values for predicting LN metastasis were 1.59 for NLR and 155.67 for PLR according to the ROC curve. Multivariate analyses showed that both PLR and NLR are significantly associated with LN metastasis independent of depth of invasion, lymphatic invasion, macroscopic type, and tumor size. The area under the ROC curve of the score system was 0.830 (95% confidence interval 0.782-0.878), showing a reliable ability to evaluate the status of nodal involvement. CONCLUSION Preoperative PLR and NLR are useful biomarkers to predict LN metastasis and the score system in our study may serve as a reliable instrument to predict LN metastasis in gastric cancer patients.

Abstract
The neural cell adhesion molecule contactin-1 (CNTN1), first identified as a member of the contactin subpopulation of the immunoglobulin superfamily, is associated with many other cell surface proteins expressed on a variety of neurocytes, contributing to their functions and maturation. It has been recently found that the abnormal expression of CNTN1 has a close correlation with tumor initiation, development, invasiveness, metastasis and prognosis. The acquired metastatic ability of malignant tumors is caused by a population of cancer cells with the capacities of invasiveness, metastasis, adherence and proliferation, in which abnormal gene expression may play an important role. This review focuses on the current advances in research of CNTN1 in the nerve system, and mainly in the malignant tumors, with an aim to provide new clues to clinical prevention, diagnosis and treatment of these malignancies.

Abstract
Background: Lymphatic vessel endothelial hyaluronan receptor-1 (LYVE-1) is a hyaluronic acid receptor that is selectively expressed in the endothelia of lymphatic capillaries. The density of lymphatic vessels expressing LYVE-1 on immunohistochemistry negatively correlates with prognosis of patients with non-small-cell lung cancer. However, the relationship between LYVE-1 serum levels and lung cancer staging is unknown. Methods: We collected blood samples from 58 lung cancer patients before treatment and measured LYVE-1 serum levels using an enzyme-linked immunosorbent assay. Results: Mean serum LYVE-1 levels were 1,420 pg/mL. Serum LYVE-1 levels correlated positively with serum albumin levels, but inversely with primary tumor size, leukocyte counts, and platelet counts by Pearson's product-moment correlation coefficient. A high cancer staging, occurrence of lymph-node metastases, and occurrence of distant metastases were significantly associated with low LYVE-1 levels. Moreover, multiple logistic regression analyses revealed that LYVE-1 levels were predictive of the presence of lymph node and distant metastases, independently of the other factors. Kaplan-Meier analysis showed that the survival of patients with serum LYVE-1 ≤1,553 pg/mL was significantly poorer than that of patients with serum LYVE-1 >1,553 pg/mL. This survival difference relative to LYVE-1 levels remained statistically significant after adjusting for age and gender by the Cox proportional-hazard analysis. Conclusion: Serum LYVE-1 is significantly low in lung cancer patients with metastasis, compared with those without. Measuring LYVE-1 levels in lung cancer patients may be useful for evaluating lung cancer progression.

Abstract
AIM: To evaluate and compare detection of lymphatic and blood vessel invasion (LVI and BVI) by hematoxylin-eosin (HE) and immunohistochemistry (IHC) in gastric cancer specimens, and to correlate with lymph node status.
METHODS: IHC using D2-40 (a lymphatic endothelial marker) and CD34 (a pan-endothelial marker) was performed to study LVI and BVI in surgical specimens from a consecutive series of 95 primary gastric cancer cases. The results of the IHC study were compared with the detection by HE using McNemar test and kappa index. The morphologic features of the tumors and the presence of LVI and BVI were related to the presence of lymph node metastasis. A χ2 test was performed to obtain associations between LVI and BVI and other prognostic factors for gastric cancer.
RESULTS: The detection rate of LVI was considerably higher than that of BVI. The IHC study identified eight false-positive cases and 13 false-negative cases for LVI, and 24 false-positive cases and 10 false-negative cases for BVI. The average Kappa value determined was moderate for LVI (κ = 0.50) and low for BVI (κ = 0.20). Both LVI and BVI were statistically associated with the presence of lymph node metastasis (HE: P = 0.001, P = 0.013, and IHC: P = 0.001, P = 0.019). The morphologic features associated with LVI were location of the tumor in the distal third of the stomach (P = 0.039), Borrmann’s macroscopic type (P = 0.001), organ invasion (P = 0.03) and the depth of tumor invasion (P = 0.001). The presence of BVI was related only to the depth of tumor invasion (P = 0.003).
CONCLUSION: The immunohistochemical identification of lymphatic and blood vessels is useful for increasing the accuracy of the diagnosis of vessel invasion and for predicting lymph node metastasis.

Abstract
Background. This study aimed at determining the relationship between vascular endothelial growth factor-C (VEGF-C), vascular endothelial growth factor receptor-3 (VEGFR-3), and contactin-1 (CNTN-1) expression in gastric cancer (GC). Methods. The expression level of CNTN-1 mRNA and CNTN-1 protein of 33 cases was determined using RT-PCR and Western Blot. And 105 cases were immunohistochemically examined for VEGF-C, VEGFR-3, and CNTN-1 expressions. Assessment of lymphatic vessel density (LVD) was also performed by D2-40 immunostaining. Then we analyzed the relationships between VEGF-C, VEGFR-3, and CNTN-1, as well as their correlations with clinicopathologic features, LVD, and survival time. Results. The positivity rate of VEGF-C, VEGFR-3, and CNTN-1 in primary tumor was 56.19%, 64.76%, and 58.09%. The expression of CNTN-1 significantly correlated with VEGF-C (P < 0.001) and VEGFR-3 (P < 0.001). All of them were closely related to TNM stage, lymphatic invasion, and lymph node involvement (P < 0.05). LVD was significantly correlated with VEGF-C (P = 0.001), VEGFR-3 (P = 0.011), and CNTN-1 expression (P < 0.001). VEGF-C, VEGFR-3, and CNTN-1 expression significantly associated with poorer prognosis (P < 0.001, P = 0.034, P = 0.012, resp.). Conclusion. CNTN-1 associated with VEGF-C and VEGFR-3 expression in GC. All of them correlated with lymphatic metastasis, which might play an important role in the lymphatic invasion via lymphangiogenesis pathway in GC.

Abstract
BACKGROUND The present study was designed to evaluate the impact of the tyrosine kinase ligands VEGF-A/C/D, PDGF-A/B on tumor dissemination and survival in gastric cancer. This is the first study analyzing all these parameters in a homogeneous patient population undergoing surgery. METHODS The expression pattern of VEGF-A/C/D and PDGF-A/B was analyzed by reverse transcriptase polymerase chain reaction (RT-PCR) in 69 samples of human gastric adenocarcinoma and correlated with tumor stage and survival. RESULTS Expression of the ligand VEGF-D significantly correlated with distant metastatic disease (P=0.00001) but not with patient survival. However, VEGF-A inversely correlated with M1 and grading, PDGF-A inversely correlated with pT and pN category. In contrast, VEGF-C and PDGF-B did not have an impact on clinicopathological parameters. CONCLUSIONS The ligand VEGF-D, rather than the other ligands or tyrosine kinase receptors analyzed, is associated with progressive disease in gastric cancer patients undergoing surgery. The VEGF-D ligand might be a helpful marker indicating disseminated disease, and targeting VEGF-D may be a potential therapeutic strategy, although limitations imposed by the selected sample population have to be considered critically.

Abstract
Purpose When performing a laparoscopic assisted gastrectomy, a function-preserving gastrectomy is performed depending on the location of the primary gastric cancer. This study examined the incidence of lymph node metastasis by the lymph node station number by tumor location to determine the optimal extent of the lymph node dissection. Materials and Methods The subjects consisted of 1,510 patients diagnosed with gastric cancer who underwent a gastrectomy between 1996 and 2005. The patients were divided into three groups: upper, middle and lower third, depending on the location of the primary tumor. The lymph node metastasis patterns were analyzed in the total and early gastric cancer patients. Results In all patients, lymph node station numbers 1, 2, 3, 7, 10 and 11 metastases were dominant in the cancer originating in the upper third, whereas station numbers 4, 5, 6 and 8 were dominant in the lower third. In early gastric cancer patients, the station number of lymph nodes with a metastasis did not show a significant difference in stage pT1a disease. On the other hand, a metastasis in lymph node station number 6 was dominant in stage pT1b disease that originated in the lower third of the stomach. Conclusions When performing a laparoscopic-assisted gastrectomy for early gastric cancer, a limited lymphadenectomy is considered adequate during a function-preserving gastrectomy in mucosal (T1a) cancer. On the other hand, for submucosal (T1b) cancer, a number 6 node dissection should be performed when performing a pylorus preserving gastrectomy.
