Brief Summary
Drug delivery in solid tumors, whether administered systemically or locoregionally, is hindered by an elevated interstitial fluid pressure (IFP). Stromal targeting therapies are in active development, aiming to enhance drug transport after systemic or locoregional delivery. To date, no clinical methods are available to quantify tumor biophysical properties (including IFP). The investigators aim to use a combination of dynamic contrast enhanced MRI and computational fluid modeling (CFD) to measure stromal IFP in patients with pancreatic cancer and in patients with ovarian or colonic peritoneal carcinomatosis (PC). Computational data will be correlated with therapy response, platinum drug penetration, and invasively measured biophysical parameters after intravenous (pancreas) or intraperitoneal (ovarian/colonic PC) administration of a platinum compound. This would be the first in depth clinical study addressing this important topic, and could pave the way to developing personalized computational based treatment approaches aimed at targeting the biophysical environment of the tumor stroma in order to enhance cancer drug delivery.

Outcome Measures
Primary Outcomes (2)
Biophysical properties of the tumor tissue - measurement of Young modulus to assess viscoelasticity
A flat-ended cylindrical indentation tip, with 5 mm diameter, will be attached to a load cell to indent the sample. After the initial contact, the control algorithm will drive the tip to indent a given depth (30% of sample's height) into the test material at a constant velocity (1 mm/s). After reaching the prescribed depth, the position of the indentation tip will be fixed at this value for a given amount of time (300 s) in order to start the stress relaxation process. Units: Pa = kg m-1 s-2
up to 1 week after surgery
Biophysical properties of the tumor tissue - measurement of hydraulic conductivity
The hydraulic conductivity of samples will be measured by detecting the amount of fluid exchange through the sample due to a hydrostatic pressure gradient in a closed system. The system includes two EasyMount Ussing diffusion chambers placed in a 2-channel EasyMount stand (Physiologic Instruments, Inc.; San Diego, CA), pressure reservoirs (syringes), and a bubble tracker device for measuring the liquid exchange. The nominal hydraulic conductivity (K') will be calculated by: K'=〖(d/D)〗\^2 L/ρgh ∆x/∆t Where L and D are the tissue thickness and tissue area (interface), d is the glass tube diameter, ρ is the liquid density, h is the liquid column height, g is the gravity acceleration, x is bubble displacement and t is time.

Study Arms (1)
DCE-MRI
EXPERIMENTALInterventions
Patients will undergo an MR scan before undergoing cytoreductive surgery. If neoadjuvant chemotherapy is administered, an extra MR scan is planned before the start of the neoadjuvant chemotherapy. During surgery, tissue samples will be taken for interstitial fluid pressure (IFP) measurement, immunohistochemistry (IHC) and characterization of biophysical properties (viscoelastic properties and hydraulic conductivity).
