- Diagnostic Test: TEG indices
- Registration Number
- NCT05517811
- Lead Sponsor
- University of Colorado, Denver
- Brief Summary
The investigators hypothesize that abnormalities in thromboelastography (TEG) parameters in patients with liver, pancreas, biliary, esophageal, colorectal, and lung adenocarcinoma can serve as biomarkers for oncologic disease burden, cancer recurrence and overall survival as well as thrombotic and hemorrhagic post-operative complications. The investigators further hypothesize that there is histologic pathology correlates to pre-operative TEG abnormalities, and that it identifies patients with virulent tumor biology.
- Detailed Description
Aim 1: Evaluate the correlation between pre-operative TEG parameters and disease burden in patients with a new diagnosis of hepatopancreaticobiliary, esophageal, colorectal, and lung adenocarcinoma vs controls with no known malignancy.
Aim 2: Explore if pre- and post-operative TEG parameters vs routine clinical coagulation parameters (platelet count, prothrombin time \[PT\], partial thromboplastin time \[PTT\]) are predictive of pre- and post-operative thrombotic (deep vein thrombosis \[DVT\], pulmonary embolism \[PE\], stroke, myocardial infarct \[MI\]) and hemorrhagic complications.
Aim 3: Evaluate if correction of TEG parameters after surgery is predictive of curative resection and if the failure of TEG parameters to correct after surgery or chemoradiothearpy is predictive of cancer recurrence and overall survival.
Aim 4: Perform proteomic analyses on the tumor microenvironment of cancer tissue samples to investigate whether tumor histology and protein composition is associated with specific TEG derangements that have been previously correlated to poor outcomes, potentially identifying a specific subtype of pancreatic cancer.
