Comparing flat dose and weight-based chemotherapy for peritoneal carcinomatosis

Official title: A Randomized Phase 2 Trial of Flat Dose vs. Weight-based Dose of Intra-peritoneal (IP) Chemotherapy for Patients Undergoing Cytoreductive Surgery and Heated Intra-peritoneal Chemotherapy (CRS/HIPEC) for Advanced Gastrointestinal Malignancy

Run by University of Kentucky · NCT04779554 · Data updated 2026-11-12

This study is testing whether giving a flat dose or a dose based on body weight of a chemotherapy drug can help people with certain cancers that have spread to the abdominal area do better after surgery.

Is this trial a fit for you?

Likely a good fit

Ideal candidates include patients diagnosed with low-grade appendiceal mucinous neoplasm, appendiceal cancer with peritoneal carcinomatosis, or colorectal cancer with peritoneal carcinomatosis who are eligible for surgery.

Probably not a fit

Patients with extra-abdominal metastases, untreated lung metastases, or significant liver metastases are unlikely to benefit from this study.

What this trial studies

This clinical trial investigates the effectiveness of flat dose versus weight-based dosing of Mitomycin C in patients undergoing cytoreductive surgery and heated intra-peritoneal chemotherapy (HIPEC) for peritoneal carcinomatosis. The study aims to determine which dosing method provides better outcomes in terms of overall survival and treatment efficacy. Participants will be randomly assigned to receive either a flat dose of 40 mg or a weight-based dose of 12.5 mg/m2 of Mitomycin C during their treatment. The trial focuses on patients with specific types of gastrointestinal malignancies that have spread to the peritoneal cavity.

Why it matters

Potential benefit: If successful, this study could lead to improved treatment protocols for patients with peritoneal carcinomatosis, potentially extending survival rates.

How similar studies have gone: Previous studies have shown promising results with HIPEC in treating peritoneal carcinomatosis, suggesting that this approach may be effective, though the specific dosing comparison is novel.
