Increased expression of vascular endothelial growth factor (VEGF) has been associated with increased lymph node metastases. The aim of this work was to determine whether VEGF-induced hyperpermeability affects peritumor interstitial convection and lymphatic drain, thus linking this growth factor with lymphatic function. Noninvasive imaging of lymphatic function induced by vascular hyperpermeabil...

BACKGROUND The presence of lymph node metastases is an important factor in breast cancer patient prognosis. Therefore, the precise identification of sentinel lymph nodes in these patients is critical. Improving current magnetic resonance (MR) imaging methods using a newly synthesized nano-size paramagnetic molecule, G6, as a contrast agent, provides an attractive means toward attaining this goa...

BACKGROUND Ultrasound (sonography, B-mode sonography, ultrasonography) examination improves the sensitivity in more than 25% compared to the clinical palpation, especially after surgery on the regional lymph node area. OBJECTIVE To evaluate the distribution of metastases during follow-up in the draining lymph node areas from the scar of primary to regional lymph nodes (head and neck, supracla...

PURPOSE To study the pattern of lymph node metastases after esophagectomy and clarify the clinical target volume (CTV) delineation of thoracic esophageal squamous cell carcinoma (ESCC). METHODS AND MATERIALS Total 1077 thoracic ESCC patients who had undergone esophagectomy and lymphadenectomy were retrospectively examined. The clinicopathologic factors related to lymph node metastasis were an...

It has been reported that suppression of protein kinase N3 (PKN3) expression in vascular and lymphatic endothelial cells results in the inhibition of tumor progression and lymph node metastasis formation. The present study investigated whether combination therapy of small interfering RNA (siRNA) against PKN3 and doxorubicin (DXR) could increase therapeutic efficacy against liver and lung metast...

The lymphatic system is a common avenue for the spread of breast cancer cells and dissemination through it occurs at least as frequently as hematogenous metastasis. Approximately 75% of primary breast cancers are estrogen receptor (ER) positive and the majority of these maintain receptor expression as lymph node (LN) metastases. However, it is unknown if ER function is equivalent in cancer cell...

BACKGROUND Peritoneal dissemination and retroperitoneal lymph node involvement are main routes for progression of epithelial ovarian cancer (EOC). Vascular endothelial growth factor (VEGF) mediated angiogenesis has been identified as an important mechanism promoting tumour progression. METHODS Tumour tissue of 100 patients with EOC was analysed for protein expression of vascular endothelial g...
