摘要: The epithelial-mesenchymal transition (EMT) and cancer stemness (CS) are reported to be pivotal phenomena involved in metastasis, recurrence, drug-resistance lung cancer; however, their effects on tumor malignancy clinical settings not completely understood. mutual association between these factors also remains elusive worthy of investigation. purpose this study was elucidate the EMT CS, effect prognosis patients with adenocarcinoma. A total 239 adenocarcinoma specimens were collected from who had undergone surgery at Kyoto University Hospital January 2001 December 2007. Both (E-cadherin,vimentin) CS (CD133, CD44, aldehyde dehydrogenase) markers analyzed through immunostaining specimens. as well patients' information integrated statistically analyzed. molecular expression E-cadherin, vimentin, CD133 significantly correlated (P = 0.003, P 0.005, < 0.001). negative correlation found E-cadherin vimentin 0.001), whereas, a positive 0.020). stronger prognostic factor than an marker. Elevated is signature marker associated Importantly, suggested key that links thereby exacerbating progression.
