Tumor-secreted extracellular vesicles (EVs) are the main mediators of cell-cell communication, permitting cells to exchange proteins, lipids, and metabolites in varying physiological pathological conditions. They contain signature tumor-derived molecules that reflect intracellular status their cell origin. Recent studies have shown tumor cell-derived EVs can aid cancer metastasis through modula...

context primary liver cancer is one of the most common and deadly malignant neoplasms worldwide. the incidence and mortality rates for hepatocellular carcinoma (hcc) are virtually identical, reflecting the poor overall survival of patients with this kind of tumor. effective therapies mostly achieved if the hcc diagnosis is made at early stages of the tumor. surveillance tests include serologic ...

primitive neuroectodermal tumor (pnet) is usually an aggressive, rapidly progressing and metastasizing tumor. occurrence of this type of tumor in the kidney is considered as unusual and few cases have been reported so far. we present a metastatic pnet arising probably from the kidney in a 17-year-old female patient with local invasion and metastasis to the stomach. pnet should be considered as ...
