Core Tip

Core tip: We herein report a case of an early-stage sarcomatoid carcinoma of the pancreas (SCP) involving successful treatment and a good prognosis. The plasma transforming growth factor (TGF)β1 and interleukin-11 levels were obviously increased according to enzyme-linked immunosorbent assay. Immunohistochemical analysis was positive for pan-cytokeratin, cytokeratin 8/18, and vimentin and negative for CD68 and lysozyme. The pathogenetic mechanism of this case shows that TGFβ1 may regulate the epithelial-to-mesenchymal transition in SCP. This case is also the first to show that TGFβ1 may regulate the epithelial-to-mesenchymal transition in early-stage SCP.
