Epithelial mesenchymal transition and tumor budding in aggressive colorectal cancer: Tumor budding as oncotarget
Epithelial mesenchymal transition (EMT) is proposed as a critical mechanism for the acquisition of malignant phenotypes by epithelial cells. In colorectal cancer, tumor cells having undergone EMT are histologically represented by the presence of tumor buds defined as single cells or small clusters of de-differentiated tumor cells at the invasive front. Tumor budding is not a static, histologica...
متن کاملTumor budding cells, cancer stem cells and epithelial-mesenchymal transition-type cells in pancreatic cancer
Pancreatic ductal adenocarcinoma (PDAC) is one of the most lethal cancers with a 5-year survival rate of less than 5%. Moreover, PDAC escapes early detection and resists treatment. Multiple combinations of genetic alterations are known to occur in PDAC including mutational activation of KRAS, inactivation of p16/CDKN2A and SMAD4 (DPC4) and dysregulation of PTEN/PI3K/AKT signaling. Through their...
متن کاملTumor budding in colorectal carcinomas.
OBJECTIVE In colorectal carcinomas, tumor budding has been defined as the presence of isolated single tumor cells or small cell clusters in the stroma at the invasive tumor margin. In this study, the relationship between tumor budding density at the invasive tumor margin and pathological parameters is investigated. MATERIAL AND METHOD Haematoxylin and eosin stained slides of 73 cases with col...
متن کاملEpithelial to mesenchymal transition correlates with tumor budding and predicts prognosis in esophageal squamous cell carcinoma.
BACKGROUND AND OBJECTIVES Epithelial to mesenchymal transition (EMT) is considered to play an important role in cancer invasion. Tumor budding is a prognostic factor in esophageal squamous cell carcinoma (ESCC). The aim of this study was to explore the correlation between EMT and tumor budding. METHODS Surgical specimens from 78 cases of ESCC resected without preoperative treatment between 20...
متن کاملCirculating cytokeratin-positive cells and tumor budding in colorectal cancer
AIM To investigate whether circulating cytokeratin-positive (CK+) cells in the mesenteric blood of resected colorectal specimens are prognostic and correlate with tumor budding. METHODS Fifty-six colorectal specimens were collected between 9/2007 and 7/2008. Blood from the mesenteric vein was drawn immediately after receiving the fresh and unfixed specimens in the pathology department. After ...
