Conditions studied: Pancreatic Cancer, Gastrointestinal Neoplasms, Colon Rectal Cancer Adenocarcinoma, Esophageal Cancer, Gall Bladder Cancer, Gastric (Stomach) Cancer, Gastrooesophageal Cancer, Gastrointestinal Stromal Tumor (GIST), Hepatobiliary Neoplasm, Liver Carcinoma, Gallbladder Carcinoma, Bile Duct Carcinoma, Carcinoma of the Large Intestine, Anal Cancer
In brief
To determine whether biomarkers assessed in blood samples can be used to detect individuals at risk for developing blood clots or worsening of their underlying disease. The ultimate goal of the study is to identify key biomarkers derived from blood that are most characteristic and informative of individuals who will go on to develop a clotting complication.
