Expression of vascular endothelial growth factor C and chemokine receptor CCR7 in gastric carcinoma and their values in predicting lymph node metastasis

AIM: To study the expression of vascular endothelial growth factor C (VEGF-C) and chemokine receptor CCR7 in gastric carcinoma and to investigate their associations with lymph node metastasis of gastric carcinoma and their values in predicting lymph node metastasis. METHODS: The expression of VEGF-C and CCR7 in gastric carcinoma tissues obtained from 118 patients who underwent curative gastrectomy was examined by immunohistochemistry. Among these patients, 39 patients underwent multi-slice spiral CT (MSCT) examination. RESULTS: VEGF-C and CCR7 were positively expressed in 52.5 and 53.4% of patients. VEGF-C expression was more frequently found in tumors with lymph node metastasis than those without it (P<0.001). VEGF-C expression was also closely related to lymphatic invasion (P<0.001), vascular invasion (P<0.01), and TNM stage (P<0.001). However, there was no significant correlation between VEGF-C expression and age at surgery, gender, tumor size, tumor location, Lauren classification, and depth of invasion. CCR7 expression was significantly higher in patients with lymph node metastasis compared with those without lymph node metastasis (P<0.001) and was also associated with tumor size (P<0.01), depth of invasion (P<0.001), lymphatic invasion (P<0.001), and TNM stage (P<0.001). However, the presence of CCR7 had no correlation to age at surgery, gender, tumor location, Lauren classification, and vascular invasion. Among the 39 patients who underwent MSCT examination, only CCR7 expression was related to lymph node metastasis determined by MSCT (P<0.05). In the current retrospective study, the sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy of VEGF-C and CCR7 expression in the diagnosis of lymph node metastasis for patients with gastric carcinoma were 73.8%, 70.2%, 72.6%, 71.4% and 72.0%, and 82.0%, 77.2%, 79.4%, 80.0% and 79.7%, respectively. After subdivision according to the combination of VEGF-C and CCR7 expression, receiver operating characteristic (ROC) analysis showed that the accuracy of the combined examination of VEGF-C and CCR7 expression in predicting lymph node metastasis was relatively high (area under ROC curve [Az]=0.83). CONCLUSION: The expression of VEGF-C and CCR7 is related to lymph node metastasis of gastric carcinoma and both of them may become new targets for the treatment of gastric carcinoma. Furthermore, the combined examination of VEGF-C and CCR7 expression in endoscopic biopsy specimens may be useful in predicting lymph node metastasis of gastric carcinoma and deciding the extent of surgical lymph node resection.     

Impact of lymph node micrometastasis in hilar bile duct carcinoma patients

AIM: To immunohistochemically examine micrometastasis and VEGF-C expression in hilar bile duct carcinoma (HBDC) and to evaluate the clinical significance of the results. METHODS: A total of 361 regional lymph nodes from 25 patients with node-negative HBDC were immunostained with an antibody against cytokeratins 8 and 18 (CAM 5.2), and immunohistochemical staining of VEGF-C was performed in 34 primary resected tumors. RESULTS: Lymph node micrometastasis was detected in 6 (24%) of the 25 patients and 10 (2.8%) of the 361 lymph nodes. Patients with micrometastasis showed significantly poorer survival rates than those without (P=0.025). VEGF-C expression was positive in 17 (50%) of 34 HBDC, and significantly correlated with lymph node metastasis (P=0.042) and microscopic venous invasion (P=0.035). CONCLUSIONS: It is suggested that immunohistochemically detected lymph node micrometastasis has an impact on the outcome of HBDC. VEGF-C expression is highly correlated with lymph node metastasis in HBDC and might therefore be a useful predictor.     

Vascular endothelial growth factor-C (VEGF-C) is a more specific risk factor for lymph node metastasis than VEGF-D in submucosal colorectal cancer

BACKGROUND/AIMS: It is useful to decide whether lymphatic involvement or lymph node metastasis exists before polypectomy or operation in submucosal colorectal cancer. Whether vascular endothelial growth factor-C (VEGF-C) or VEGF-D could predict lymph node metastasis and lymphatic involvement is uncertain. METHODOLOGY: Expression of the VEGF-C and VEGF-D in human submucosal colorectal cancers was investigated in paraffin-embedded stepwise sections by means of immunohistochemistry, and the correlation between immunohistochemical expression pattern and clinicopathological features was also evaluated. RESULTS: The results showed that VEGF-C overexpression correlated with lymphatic involvement (P = 0.01) and lymph node metastasis (P = 0.02), but VEGF-D overexpression did not correlate significantly. In multivariate analysis lymphatic invasion was the predictive factor (P = 0.0129), but VEGF-C positivity was not predictive (P = 0.3437). CONCLUSIONS: These results may suggest that VEGF-C is a more specific risk factor for lymph node metastasis than VEGF-D in submucosal colorectal cancer.

Vascular endothelial growth factor C and D expression correlates with lymph node metastasis and poor prognosis in patients with resected esophageal cancer

Vascular endothelial growth factors C (VEGF-C) and D (VEGF-D) are important lymphangiogenic factors in human cancers. We studied the expression of VEGF-C and VEGF-D using immunohistochemistry in 73 resected esophageal cancer specimens, and correlated the results with patient clinicopathologic features and survival. High expression of VEGF-C was identified in 40 (54.7%) patients, and it correlated positively with histological grade (p=0.038), tumor stage (p=0.01), depth of tumor invasion (p=0.036) and lymph node metastasis (p=0.001). In 48 of 73 (65.7%) tumors, the VEGF-D protein was also expressed at high levels. VEGF-D immunoreactivity significantly correlated with tumor location (p=0.027), size of tumor (p=0.015), histological grade (p=0.02), depth of invasion (p=0.001) and lymph node metastasis (p=0.018). In logistic multivariate analysis, high expression of VEGF-C (OR 1.941, 95% CI 1.263-7.289, p=0.024) was associated with lymph node metastasis. Calculating the prognostic relevance revealed that both VEGF-C and VEGF-D correlated with decreased overall survival (p=0.01, p=0.003), disease free survival (p=0.02, p=0.006), and cancer-specific survival (p=0.03, p=0.005). In conclusion, our results suggest that high levels of both VEGF-C and VEGF-D proteins are associated with lymph node involvement, and that VEGF-C expression is an independent predictor of risk for lymph node metastasis in esophageal cancer. In locally advanced disease, overexpression of VEGF-C and VEGF-D may be useful in identifying patients who are more likely to have a poor prognosis even after curative resection.
