Official Title: Single Arm Study Treating Patients of Peritoneal Surface Malignancy (Colorectal, Appendical, Pseudomyxoma, Gastric) With Cytoreductive Surgery and Hyperthermic Intraperitoneal Mitomycin-C

Brief Summary:

This is a clinical study investigating the new treatment of surgery combined with intraperitoneal mitomycin-C for patients with gastrointestinal cancer that has spread to the peritoneal (abdominal cavity) surface. Mitomycin-C to be used in this procedure is approved by the U.S. Food and Drug Administration (FDA)for many different cancers including gastrointestinal cancer. Giving mitomycin C via the intraperitoneal route is not FDA approved and is an investigation therapy. Cytoreductive surgery plus intraperitoneal chemotherapy can be offered as standard of care outside of a clinical trial. However, since this is an unproven and potentially more effective but a more toxic approach, the investigators are performing this procedure under an IRB approved clinical trial in order to better evaluate the risks and benefits of this approach.

A standardized, evidence-based approach is currently lacking for patients with peritoneal surface malignancy from gastrointestinal origin. A clinical trial with surgical quality assurance and modern hyperthermic intraperitoneal chemotherapy incorporating critical assessment of disease burden, determinants of complete cytoreduction, treatment-related toxicity, quality of life and survival is imperative. Theoretically, cytoreductive surgery is performed to treat macroscopic disease, and hyperthermic intraperitoneal chemotherapy is used to treat microscopic residual disease with the objective of removing disease completely in a single procedure.


Detailed Summary:

Patients with peritoneal surface malignancy from gastrointestinal (GI) cancers almost uniformly succumb to advanced locoregional disease in the form of intractable ascites, malignant visceral obstruction and cancer cachexia. The natural history of peritoneal carcinomatosis from GI malignancies is inexorably lethal with median overall survival of approximately 5 months 7, as patients with disease confined to the peritoneum remain at increased risk of synchronous occult hematogenous metastases. While systemic therapy improves outcome in patients with hematogenous disease spread, improvements are needed in the control of peritoneal surface malignancy, which is known to be relatively resistant to systemic agents owing principally to the presence of a peritoneal-plasma partition. Moreover, the results of surgical resection alone for peritoneal dissemination of GI cancer have been disappointing given the difficulty in clearing surgically all microscopic disease foci. The infusion of chemotherapy into the peritoneal cavity provides distinct pharmacokinetic advantages. The addition of hyperthermia potentiates the effect of intra-peritoneal chemotherapy through anti-tumor synergism, without systemic drug absorption.

Mitomycin- C is the cytotoxic agent of choice for this purpose, one that has been studied most extensively for hyperthermic intra-peritoneal chemotherapy in patients with peritoneal carcinomatosis of gastrointestinal origin. Mitomycin- C has also been shown to demonstrate consistent pharmacokinetics, favorable toxicity profile, and hyperthermia-facilitated tumor cytotoxicity, which is enhanced under conditions of tumor hypoxia; furthermore, Mitomycin- C contributes to improved outcomes after optimal cytoreduction. Hence, the delivery of intra-peritoneal heated chemotherapy has the advantage of dose-dense regional delivery of cytotoxic agents with relatively little syst

Current Primary Outcome: Evaluate the technical parameters [ Time Frame: through subject discontinuation or 12 months after initial study treatment ]

This prospective trial will evaluate the technical parameters including completeness of cytoreduction, achievement of hyperthermia, morbidity and mortality in patients with peritoneal carcinomatosis of colorectal, gastric, appendical, pseudomyxoma peritonei and peritoneal mesothelioma origin undergoing cytoreductive surgery and hyperthermic intraperitoneal chemotherapy with Mitomycin- C.


Original Primary Outcome: Same as current

Current Secondary Outcome: Progression-free survival [ Time Frame: up until 5 years ]

Determination of disease progression will be based on:

  • Radiological (CT ± PET), and/or
  • Surgical (laparoscopic or open exploration) evidence of recurrent disease. Peritoneal disease progression will be confirmed by cytology or histology revealing cells morphologically consistent with malignant tumor cells


Original Secondary Outcome: Same as current
