Breast cancer metastasis involves lymphatic dissemination in addition to hematogenous spreading. Although stromal lymphatic vessels (LVs) serve as initial metastatic routes, roles of organ-residing LVs are underinvestigated. Here we show that lymphatic endothelial cells (LECs), a component of LVs within pre-metastatic niches, are conditioned by triple-negative breast cancer (TNBC) cells to acce...

The lymphatic system is important in tissue fluid balance regulation, immune cell trafficking, edema, and cancer metastasis, yet very little is known about the sequence of events that initiate and coordinate lymphangiogenesis. Here, we characterize the process of lymphatic regeneration by uniquely correlating interstitial fluid flow and lymphatic endothelial cell migration with lymphatic functi...

BACKGROUND Oral squamous cell carcinoma (OSCC) is the most common oral malignancy that preferentially spreads to the cervical lymph node which, when involved, complicates the anticancer therapy and threatens the patient life. It was suggested that lymph node metastasis may be facilitated by lymphangiogenesis. VEGF-C is one of the most important lymphangiogenic inducers that promotes the lymphat...

The important malignant behavior of esophageal cancer is lymph node metastasis of cancer cells through lymphatic ducts, whereas the lymph node metastasis directly affects treatment methods, local recurrence and long-term survival. In recent years, studies on lymphangiogenesis mechanism and regulatory factors in cancer tissue have been a hotspot in tumor research. Some studies have revealed that...

Here, we collected the information of 17304 and 2014 inpatients with colorectal cancer (CRC) from general hospitals of China and Japan respectively, and analyzed microscopic and macroscopic aspects, even stratified by the age and gender. It was found that Chinese CRC patients showed younger prone, more rectal and ascending cancers, less sigmoid and transverse cancers, larger size, less invasion...

Breast involution following pregnancy has been implicated in the high rates of metastasis observed in postpartum breast cancers; however, it is not clear how this remodeling process promotes metastasis. Here, we demonstrate that human postpartum breast cancers have increased peritumor lymphatic vessel density that correlates with increased frequency of lymph node metastases. Moreover, lymphatic...

Metastasis is one of the major causes of cancer-related death. It is a complex biological process involving multiple genes, steps, and phases. It is also closely connected to many biological activities of cancer cells, such as growth, invasion, adhesion, hematogenous metastasis, and lymphatic metastasis. Fucoidan derived from Undaria pinnatifida sporophylls (Ups-fucoidan) is a sulfated polysacc...

The aim of the study was to study the expression of hypoxia-inducible factor-1α (HIF-1α) and P-glycoprotein (P-gp) and analyze its correlation with human papillomavirus (HPV) infection. From January, 2012 to May, 2014, 72 cases of non-small cell lung cancer (NSCLC) pathologic tissue samples were selected from the study group. Fifty-four lung benign lesions were selected to serve as the control ...

BACKGROUND Breast carcinoma is the second commonest cancer in women after non-melanoma skin cancers and, excluding melanoma, the most common tumor to metastasize to the skin in women. Cutaneous metastasis from breast cancer has varied presentations but there is no well-established classification which includes them all. OBJECTIVE AND CONCLUSION We report a 69 year-old lady with advanced prima...

Breast carcinoma is the most common malignant tumor in women. For these patients, lymph node metastasis is one of the most important prognostic factors. Recent studies suggest that lymphangiogenesis can contribute to the lymphatic metastasis in tumors. Several members of vascular endothelial growth factor (VEGF) family, such as VEGF-C, VEGF-D, and VEGF receptor-3 (VEGFR-3), have been found to p...
