Regional lymph node metastasis is one of the important indicators of cutaneous malignant melanoma. Newly formed lymphatic vessels are considered to provide a route whereby tumor cells can migrate to the lymph nodes. Both vascular endothelial growth factors (VEGF) -C and -D have been confirmed to participate in tumor lymphangiogenesis, but the prognostic significance of VEGF-C, VEGF-D, and lymphangiogenesis in cutaneous malignant melanoma remains controversial. To clarify the effects of these factors and to evaluate the relationships between lymphangiogenesis, lymph node metastasis, and prognosis in patients with malignant melanoma, the expressions of VEGF-C, VEGF-D, and their receptor (VEGFR) -3 were detected by immunohistochemistry and reverse transcriptase-polymerase chain reaction. The expressions of both VEGF-C and VEGF-D proteins were concomitantly detected in the cytoplasm of the malignant cells. VEGF-C and VEGF-D expressions were associated with VEGFR-3 expression and were significantly correlated with both peritumoral lymphangiogenesis and lymph node metastasis. The incidence of peritumoral lymphatic vessels was significantly higher in lymph node metastatic melanomas than that in nonmetastatic melanomas. Univariate and multivariate analyses indicated that VEGF-C and VEGF-D were independent prognostic factors for overall survival and disease-free survival in patients with malignant melanoma. This study suggests that both VEGF-C and VEGF-D are involved in peritumoral lymphangiogenesis and lymphatic metastasis. VEGF-C and VEGF-D expression may be clinically useful indicators for prognostic evaluation in patients with cutaneous malignant melanoma.

Lymph node metastasis is an important prognostic indicator for disease progression and is crucial for therapeutic strategies of epithelial ovarian carcinoma. Vascular endothelial growth factor (VEGF)-D has been confirmed to have potent lymphangiogenic function in experimental models, but the role in the progression of human ovarian carcinoma remains presently controversial. The purpose of this study was to investigate the prognostic significance of VEGF-D and the presence of intratumoral lymphatics in patients with epithelial ovarian carcinoma. The VEGF-D expression was evaluated by immunohistochemistry in 78 specimens of epithelial ovarian carcinoma and tumoral lymphatic vessels were measured by D2-40. The expression of VEGF-D protein was detected in the cytoplasm of the tumor cells and in stroma occasionally. The high expression of VEGF-D was closely associated with the FIGO stage, intratumoral lymphatic vessels, tumoral lymphatic invasion, and lymph node metastasis as well as a shorter overall survival. Univariate and multivariate analysis indicated that VEGF-D, intratumoral lymphatics, and lymphatic invasion were independent prognostic factors for overall survival and disease-free survival in patients with epithelial ovarian carcinoma. We conclude that VEGF-D plays an essential role in tumoral lymphangiogenesis and lymphatic spread, VEGF-D expression, and the intratumoral lymphatics may be clinically useful indicators for prognostic evaluation in patients with epithelial ovarian carcinoma.

Vascular endothelial growth factor (VEGF)-C and VEGF-D induce lymphangiogenesis through activation of VEGF receptor 3 (VEGFR-3) and have been implicated in tumor spread to the lymphatic system. Lymph node dissemination critically determines clinical outcome and therapeutic options of patients with non-small cell lung cancer (NSCLC). However, the relationship of VEGF-C, VEGF-D, and lymph node metastasis in cancers, including NSCLC, is still controversial. To evaluate the relationship between lymphangiogenesis and lymph node metastasis, the expression of VEGF-C and VEGF-D in NSCLC tumors were detected by immunohistochemistry and quantitative real-time polymerase chain reaction (QRT-PCR). QRT-PCR revealed that in marginal region VEGF-C and VEGF-D mRNA was significantly higher than in tumor center, and VEGF-D mRNA was also higher than that in peritumoral lung tissue. Immunohistochemically, we observed the same heterogeneous expression of VEGF-C and VEGF-D proteins. The group with high expression of VEGF-C and VEGF-D in marginal region had a higher incidence of lymph node metastasis compared with the group with low expression. Furthermore, the group with high expression of VEGF-D in marginal region had a higher incidence of lymphatic invasion. The group with high peritumoral lymphatic vessel density (LVD) had higher expression of VEGF-C and VEGF-D mRNA compared with the group with low peritumoral LVD. Our studies suggested that the expression of VEGF-C and VEGF-D at invasive edge was significantly associated with lymph node metastasis or lymphatic invasion in patients with NSCLC and may be involved in regulation of lymphangiogenesis and lymph node metastasis in NSCLC.

Bladder cancer is frequently associated with regional lymph node metastasis at the time of diagnosis or after initial treatment, and lymph node metastasis is crucial for clinical therapeutic strategies. Lymphangiogenesis, detected by antibodies specific for lymphatic endothelial cells, is correlated with cancer spread, but the mechanisms that underlie lymphatic spread and the role of lymphangiogenesis in cancer metastasis has been less clear. The aim of this study was to investigate the association of vascular endothelial growth factor (VEGF)-D expression, intratumoral lymphatics, and lymphatic invasion associated with lymph node metastasis as well as the prognostic analysis in patients with bladder transitional cell carcinoma (TCC). The VEGF-D expression was evaluated by immunohistochemistry in 72 specimens, and tumoral lymphatic vessels were measured by D2-40. Counts of lymph vessels were taken in intratumoral and peritumoral areas. Survival analyses and their independent roles were investigated using univariate and multivariate analysis models. The high expression of VEGF-D was closely associated with the intratumoral lymphatic vessels, tumoral lymphatic invasion, and lymph node metastasis as well as a shorter overall survival. Higher lymphatic vessel density, intratumoral lymphatics, and lymphatic invasion showed a significant association with lymph node metastasis. Univariate analysis indicated that VEGF-D, intratumoral lymphatics, and lymphatic invasion were associated with overall survival, but they were not independent prognostic factors for bladder TCC in multivariate analysis. We conclude that VEGF-D plays an essential role in tumoral lymphangiogenesis. Intratumoral lymphatics and lymphatic invasion are important predictive factors of pelvic lymph node metastasis in patients with bladder cancer.
