This paper highlights the methodology in measuring interstitial pressure in pancreatic adenocarcinoma tumors. A Millar
Mikrotip pressure catheter (SPR-671) was used in this study and a system was built to amplify and filter the output signal
for data collection. The Millar pressure catheter was calibrated prior to each experiment in a water column at 37°C, range
of 0 to 60 inH2O (112 mmHg), resulting in a calibration factor of 33 mV / 1 inH2O. The interstitial pressures measured in
two orthotopically grown pancreatic adenocarcinoma tumor were 57 mmHg and 48 mmHg, respectively. Verteporfin
uptake into the pancreatic adenocarcinoma tumor was measured using a probe-based experimental dosimeter.
