Clinical significance and therapeutic implication of CD200 in pancreatic cancer.
Background: CD200, a negative regulator of T cells as well as a marker for cancer stem cells, represents a significant prognostic factor and potential therapeutic target in certain cancers. However, its clinical significance remains unknown in pancreatic ductal adenocarcinoma (PDAC).
Methods: CD200 was assessed in 220 resected PDAC patients who underwent surgery with or without neoadjuvant chemoradiotherapy (NACRT). We examined the clinicopathological outcomes associated with CD200 and further assessed its clinical implications regarding immunological and cancer stem cell properties.
Results: NACRT was associated with higher CD200 expression (66.4 % vs. 32.2 %, P < 0.001) compared to upfront surgery. CD200 was identified as an independent poor prognostic factor in NACRT (hazard ratio 1.90, 95 % confidence interval 1.12-3.23, P = 0.016), but not in upfront surgery patients. Post-recurrence survival was significantly worse in CD200+ patients compared to CD200- patients in the NACRT group, but there was no significant difference observed in the upfront surgery group. CD200 expression was correlated with significantly lower levels of CD4+, CD8+, and CD45RO+ tumor-infiltrating lymphocytes. Furthermore, the correlation of CD200 with pancreatic cancer stem cell markers CD44/CD24/ESA was stronger in irradiated human pancreatic cancer cells.
Conclusions: Our data underscore novel roles for CD200 in immune evasion as well as therapy resistance in pancreatic cancer. CD200 may represent a novel poor prognostic predictive factor and potential therapeutic target for PDAC with NACRT.
期刊介绍：
Pancreatology is the official journal of the International Association of Pancreatology (IAP), the European Pancreatic Club (EPC) and several national societies and study groups around the world. Dedicated to the understanding and treatment of exocrine as well as endocrine pancreatic disease, this multidisciplinary periodical publishes original basic, translational and clinical pancreatic research from a range of fields including gastroenterology, oncology, surgery, pharmacology, cellular and molecular biology as well as endocrinology, immunology and epidemiology. Readers can expect to gain new insights into pancreatic physiology and into the pathogenesis, diagnosis, therapeutic approaches and prognosis of pancreatic diseases. The journal features original articles, case reports, consensus guidelines and topical, cutting edge reviews, thus representing a source of valuable, novel information for clinical and basic researchers alike.
