Updated project metadata. Determination of pancreatic cyst fluids (PCF) peptidome and proteome in 5 distinct patient groups: malignant (CAs), intraductal papillary mucinous neoplasms (IPMNs), mucinous cystic neoplasms (MCNs), serous cystic neoplasms (SCNs), and pseudocysts (PCs). The PCF <5kDa fraction, referred as the degradome, and proteome profiles were determined using a LTQ-Orbitrap Elite mass spectrometer coupled with a nanoAcquity LC system. Qualitative LC-MS/MS analyses were ran on pooled samples from all patients.
