Abstract
Pancreatic cancer (PC) is a lethal, malignant cancer that bears high mortality rates. Due to its lack of noticeable symptoms, it is often diagnosed late and current pancreatic cancer therapies are ineffective with poor prognosis. Despite the high mortality and poor survival of PC patients, there is limited information on factors propagating resistance. Resistance to standard therapies in pancreatic cancer patients is partly associated with the presence of a subpopulation of highly plastic “stem-like” cells (pancreatic cancer stem cells: paCSC) in tumors. In this connection, it is important to have a strong understanding of the paCSC population, especially its distinct characteristics, in order to engineer new therapies to target these resistant cells. Therefore, the purpose of this investigation is to highlight and discuss PaCSC and their specific surface markers. Overall, in this study, we searched MEDLINE, EMBASE, the Cochrane Library, Web of Science, and ISI Proceedings for observational studies relating to the PaCSC and PC. Pancreatic cancer stem cells exhibit specific immune characteristics on their surface. The CD133, CD44, CD24, ALDH1, c-Met, DCLK1, CXCR4, EpCAM and ABCG2 are prominent Pa-CSC markers. As PaCSCs drive tumorigenesis and metastasis, their manipulation approaches would have widespread clinical implications and hence improve outcomes in pancreatic cancer.
