Soluble PD-1, PD-L1 and BTLA as prognostic biomarkers in patients with pancreatic adenocarcinoma

The present invention relates to a prognostic method of pancreatic cancer. In the present study, the inventors use specific antibodies to monitor the concentrations of soluble forms of PD-1 and PD-L1 and BTLA in plasma of advanced PDAC patients, which are not eligible for resection, by ad hoc developed ELISAs. They showed that high plasma levels of these immune checkpoints correlate with poor outcome and can be used as prognostic factors in non-resectable PDAC. Thus the present invention relates to a method for predicting the survival time of a patient suffering from a pancreatic cancer comprising determining in a sample obtained from the patient the expression level of PD-1 and/or PD-L1.
