Primary hepatic angiosarcoma is a rare type of tumor with a poor prognosis. To the best of our knowledge, curative surgery of a metastatic gastrointestinal angiosarcoma from a hepatic angiosarcoma has not been reported previously. In the present report, a case of colonic metastasis from a primary hepatic angiosarcoma is discussed. A rapidly growing mass was identified in the liver of an 84-year-old Japanese male who underwent a subsegmentectomy of the liver. Microscopic examination determined that the mass was an angiosarcoma composed of sheets of spindle cells...

Tumor growth and metastasis are dependent on angiogenesis. The overexpression of integrin αvβ3 on angiogenic vessels and on numerous malignant human tumor cells suggests that these labeled ligands of integrin are potentially suitable for molecular imaging and in targeted therapy of tumors. In previous studies, we added a β-lactamase variant with reduced immunogenicity to the cyclic peptide RGD4C, resulting in the fusion protein RGD4CβL, which is suitable for use in targeted enzyme prodrug therapy (TEPT), a promising treatment for tumors...

Colorectal cancer (CRC) is one of the most common types of malignant tumor in the world and occurs through a multi-step process resulting from the accumulation of genetic and epigenetic alterations of the genome. Although the molecular mechanisms of the pathogenesis of CRC remain unclear, the inactivation of tumor suppressor genes (TSGs) through promoter methylation serves an important role. Aberrant methylation is a well-defined marker of CRC. At present, the epigenetic silencing of protocadherin 10 (PCDH10) has been identified as an important TSG with key roles in colorectal carcinogenesis, invasion and metastasis as a frequent and early event...
