|Colon Carcinoma Liver and Intrahepatic Bile Duct Carcinoma Pancreatic Carcinoma||Procedure: Biospecimen Collection Other: Laboratory Biomarker Analysis Other: Laboratory Procedure|
I. To determine if our optical polarimeter device is able to measure tissue stiffness across several human cancer types ex vivo.
I. To describe the inter- and intra-tumor heterogeneity of tissue stiffness. II. To determine if the measurements made by the optical polarimeter device are non-destructive.
I. Perform multi-variable cross-correlation statistical analysis to determine relationships between: tissue stiffness characteristics, molecular level signatures, and cellular level properties, and if numbers permit, response to treatment.
Patients undergo fresh tumor tissue collection at the time of surgery. The fresh tumor tissue samples are analyzed for tissue stiffness measurements using an optical polarimeter device and cell viability using an automated cell counter.
