Other biomarkers such as Carcinoembryonic Antigen (CEA) or cell surface associated mucin 1 (MUC-1) have also shown promise in detecting pancreatic cancer by sampling the circulation, but they have suffered from the same lack of specificity and sensitivity that prevent them from being routinely recommended for patients [3,4]. This evidence concerns the gene MUC1 and familial pancreatic carcinoma.
