Characterization of Biophysical Stromal Properties in Human Cancer: Towards Personalized Computational Oncology (DCE-MRI)

September 16, 2026 updated by: University Hospital, Ghent

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.

Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating).

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: DCE-MRI
Procedure: MRI

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).

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Biophysical properties of the tumor tissue - measurement of Young modulus to assess viscoelasticity
Time Frame: up to 1 week after surgery

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
Time Frame: up to 1 week after surgery

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.
up to 1 week after surgery

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
CFD modeling
Time Frame: up to 12 months after surgery

Develop and validate a computational fluid dynamics (CFD) model to calculate interstitial fluid pressure based on dynamic contrast enhanced (DCE)-MRI data. This approach is based on Darcy's law (v=-K∇P) with v the velocity and ∇P the pressure gradient. The boundary condition at the outer edge of the tumor will be set to equal the convective outflow velocity values (v), as calculated during DCE-MRI. Hydraulic conductivity values (K) will be based on the tissue sample measurements. Other operational parameters such as the fluid properties (e.g. viscosity of interstitial fluid) will be based on literature values.
up to 12 months after surgery
Measurement of Pt penetration
Time Frame: up to 24 months after surgery

Quantitative laser ablation-ICP-MS will be used to analyze platinum penetration/distribution in peritoneal metastases that are left in situ during IP drug delivery but resected after completion of the procedure. The pixel intensities will be bilinearily interpolated and the Pt penetration depth set at 50% of the maximum intensity values.
up to 24 months after surgery
