Lymph node metastasis (LNM) in gastric cancer is associated with higher rate of cancer recurrence and poor prognosis. As a result, a reliable biomarker for the prediction of LNM is important and would be valuable in the clinical practice. MiRNA microarray revealed that ten miRNAs were expressed significantly different among patients with or without LNM. A total of 46 gastric cancer patients were enrolled and divided into two groups (23 in each group) according to the presence or absence of LNM. RT-PCR of these 10 miRNAs was investigated and compared between the two groups. MiR-1207-5p was significantly upregulated in gastric cancer patients without LNM compared with those with LNM. Patients with upregulated miR-1207-5p had less scirrhous stromal reaction, less lymphovascular invasion, and earlier pathological T category, N category, and TNM stage, compared with those with downregulated or unchanged miR-1207-5p. Multivariate analysis showed that stromal reaction type, lymphovascular invasion, pathological T category and TNM stage, and expression of miR-1207-5p were independent risk factors of LNM. MiR-1207-5p could serve as a useful biomarker in the prediction of LNM in gastric cancer.

Abstract ObjectiveTo explore the effects of gender and age differences in the risk factors for lymph node metastasis in patients and analysis prognosis of patients of early gastric cancer (EGC). MethodsA total of 411 patients with EGC who underwent surgical treatment at the First Affiliated Hospital of Anhui Medical University from 2011 to 2017 were included in this study and grouped according to gender and age. Retrospective analysis of the effects of gender and age on tumor size, histological type, depth of invasion, and ulcer type was performed, and differences in the clinicopathological characteristics of lymphovascular invasion were noted. Follow-up of the postoperative recurrence and metastasis of the patients and analysis of their prognosis were finally conducted. All follow-ups ended in August 2020. ResultThe participants in this study ranged in age from 25 years to 85 years (average, 60.27 ± 10.77 years). A total of 57 (13.9%) of the patients showed lymph node metastasis. Females accounted for 25.5% (105/411) while males accounted for 74.5% (306/411) of the study population. Patients aged ≤60 years accounted for 55.5% (228/411) while patients aged >60 years accounted for 44.5% (183/411) of the study population. Univariate analysis of male patients showed that tumor size, depth of tumor invasion, ulcerative tumors, and lymphovascular invasion are related to lymph node metastasis (P < 0.05). Univariate analysis of female patients showed that tumor size, depth of tumor invasion, tumor histology, and lymphovascular invasion are related to lymph node metastasis (P < 0.05). Univariate analysis of patients aged ≤60 years showed that depth of tumor invasion, ulcerative tumors, and lymphovascular invasion are related to lymph node metastasis (P < 0.05). Univariate analysis of patients aged >60 years showed that depth of tumor invasion, ulcerative tumors, and lymphovascular invasion are related to lymph node metastasis (P < 0.05). Multivariate analysis of male patients, female patients, and patients aged ≤60 years showed that depth of tumor invasion is an independent risk factor for lymph node metastasis. Multivariate analysis of patients aged >60 years showed that depth of tumor invasion, ulcerative tumors, and lymphovascular invasion are independent risk factors for lymph node metastasis. ConclusionThe risk factors for lymph node metastasis in patients with EGC differed according to gender and age. The results provide a reference for choosing suitable treatment options for these patients.

Abstract Background Most lymph node metastasis (LNM) models for early gastric cancer (EGC) include lymphovascular invasion (LVI) as a predictor. However, LVI must be confirmed by postoperative pathology. In this study, we aimed to develop a model for predicting the risk of LNM/LVI in EGC using preoperative factors. Methods EGC patients who underwent radical gastrectomy at Fujian Medical University Union Hospital and Sun Yat-sen University Cancer Center (n = 1460) were selected as the training set. The risk factors of LNM/LVI were investigated. Data from the International study group on Minimally Invasive surgery for GASTRIc Cancer trial (n = 172) were selected as the validation set. Results In the training set, the incidence of LNM/LVI was 21.6%. The 5-year cancer-specific survival rates of patients with and without LNM/LVI were 92.4 and 95.0%, respectively, with significant difference (P = 0.030). Multivariable logistic regression analysis showed that the four independent risk factors for LNM/LVI were female, tumor larger than 20 mm, submucosal invasion and undifferentiated tumor histological type (all P <  0.05); the area under the curve (AUC) was 0.694 (95% confidence interval [CI]: 0.659–0.730). Patients were divided into low-risk, intermediate-risk, high-risk and extremely high-risk groups by recursive partitioning analysis; the incidences of LNM/LVI were 5.4, 12.6, 24.2 and 37.8%, respectively (P <  0.001). The AUC of the validation set was 0.796 (95%CI, 0.662–0.851) and the predictive performance of the LNM/LVI risk in the validation set was consistent with that in the training set. Conclusions The risk of LNM/LVI in differentiated mucosal EGC is low, which indicated that endoscopic resection is a treatment option. The risk of LNM/LVI in undifferentiated mucosal EGC and submucosa EGC are high and gastrectomy with lymph node dissection is suggested.

17 Background: An accurate preoperative assessment of potential lymph node metastasis is useful in the decision for the treatment strategy of early gastric cancer. The aim of this study was to retrospectively evaluate the accuracy of preoperative assessment of lymph node status with multi detector-row computed tomography (MDCT) and endoscopic ultrasound (EUS). Methods: We had analyzed 1,104 patients with early gastric cancer who underwent gastrectomy with lymph-node dissection at Seoul National University Bundang Hospital from May 2003 to July 2011. Patients were underwent preoperative MDCT in 1,104 and EUS in 1,028. Lymph nodes were considered positive for metastasis if they were larger than 8mm in the short axis diameter of MDCT. The criteria of EUS for metastatic lymph nodes are rounded nodes larger than 8 mm diameter with hypoechogenicity. The clinical N staging of preoperative MDCT and EUS was compared to the postoperative pathological finding. Results: The overall diagnostic accuracy of MDCT and EUS for determining lymph node metastasis was 89.1% and 90.5%. In MDCT, the rate of overestimation of lymph node metastasis was 8.20% (91/1104) and underestimation was 8.7% (96/1104). Tumor size (>2cm) was significant related with overestimation (p=0.007). Underestimation of clinical N staging was related with female (p=0.025, OR 2.025), lymphovascular invasion (p<0.0001, OR 7.807), positive EGFR (p=0.015, OR 2.566) and tumor size (>2cm) (p=0.009, OR 3.221). In EUS, overestimated lymph node metastasis was 5.40% (56/1028) and underestimation was 9.6% (99/1028). No factor was significantly related with overestimation. Underestimation of lymph node metastasis was related with female (p=0.020, OR 2.049), lymphovascular invasion (p<0.0001, OR 11.716), positive EGFR (p=0.024, OR 2.489) and tumor size (>2cm) (p=0.020, OR 2.774). Conclusions: For preoperative assessment of lymph node metastasis in early gastric cancer, MDCT and EUS showed high diagnostic accuracy. Both MDCT and EUS, female, lymphovascular invasion, positive EGFR, large tumor size (>2cm) were related to underestimation of clinical N staging. We proposed that careful attention is required to choose treatment based on clinical N staging by MDCT and EUS.

AbstractLymph node metastasis (LNM), a common metastatic gastric-cancer (GC) route, is closely related to poor prognosis in GC patients. Bone marrow-derived mesenchymal stem cells (BM-MSCs) preferentially engraft at metastatic lesions. Whether BM-MSCs are specifically reprogrammed by LNM-derived GC cells (LNM-GCs) and incorporated into metastatic LN microenvironment to prompt GC malignant progression remains unknown. Herein, we found that LNM-GCs specifically educated BM-MSCs via secretory exosomes. Exosomal Wnt5a was identified as key protein mediating LNM-GCs education of BM-MSCs, which was verified by analysis of serum exosomes collected from GC patients with LNM. Wnt5a-enriched exosomes induced YAP dephosphorylation in BM-MSCs, whereas Wnt5a-deficient exosomes exerted the opposite effect. Inhibition of YAP signaling by verteporfin blocked LNM-GC exosome- and serum exosome-mediated reprogramming in BM-MSCs. Analysis of MSC-like cells obtained from metastatic LN tissues of GC patients (GLN-MSCs) confirmed that BM-MSCs incorporated into metastatic LN microenvironment, and that YAP activation participated in maintaining their tumor-promoting phenotype and function. Collectively, our results show that LNM-GCs specifically educated BM-MSCs via exosomal Wnt5a-elicited activation of YAP signaling. This study provides new insights into the mechanisms of LNM in GC and BM-MSC reprogramming, and will provide potential therapeutic targets and detection indicators for GC patients with LNM.
