B7-H4 is a prognostic biomarker for poor survival in patients with pancreatic cancer

B7-H4 belongs to the immune costimulatory B7 family and is thought to negatively regulate T-cell mediated immunity, and may contribute an important role in tumor immune evasion. Although the expression of B7-H4 has been observed in human pancreatic cancer, the prognostic significance of this expression is poorly understood. This present study explored the prognostic value of B7-H4 in pancreatic cancer. Patients with pancreatic cancer and healthy controls were recruited at the Second Affiliated Hospital to Zhejiang University from January 2011 to December 2014.
