• Conditions: Peritoneal Carcinomatosis; Cytoreductive Surgery; Hyperthermic Intraperitoneal Chemotherapy

• Registration Number: NCT05063019
• Lead Sponsor: Chang Gung Memorial Hospital

Brief Summary

This is a prospective observational study which will recruit 90 participants over a three-year period to investigate whether adding magnetic resonance imaging and enterography to routine computed tomography study can better predict the extend of peritoneal carcinomatosis over computed tomography alone.

Detailed Description

Hyperthermic Intraperitoneal Chemotherapy (HIPEC) is a new option for patients with peritoneal carcinomatosis and the effectiveness of HIPEC depends on the extend of disease. Currently, pre-operative imaging peritoneal cancer index (PCI) is used to predict the intraoperative tumor extend and completeness of cytoreduction. However, the investigators' previous study and literature review show that imaging PCI usually underestimated intraoperative PCI, resulting in subsequent Open-Close operation. The investigators hypothesize that magnetic resonance imaging (MRI) is a better predictor of the intra-operative PCI than computed tomography (CT), and MR Enterography can better represent tumor deposits in the small intestine. This study aims to test whether the addition of MRI and MR Enterography to CT study improves the prediction performance of the intraoperative PCI and completeness of optimal cytoreduction over CT alone.

Primary Outcome Measures

Name	Time	Method
Predicting intraoperative PCI scores for patients with peritoneal carcinomatosis, using MR Enterography and CT	36 months	The Sugarbaker's Peritoneal Cancer Index scores according to the MR enterography and CT images will be calculated pre-operatively and will be compared to the standard PCI scores obtained during operation. Basically, the scoring system divides the abdominopelvic cavity into 13 separate regions, and each region is scored 0-3 points as follows: 0 point, the absence of tumor; 1 point, tumors \< 0.5 cm in diameter; 2 points, tumors 0.5-5 cm in diameter; 3 points, tumors \> 5 cm in diameter.
