Individualized Response Assessment to Heated Intraperitoneal Chemotherapy (HIPEC) for the Treatment of Peritoneal Carcinomatosis From Ovarian, Colorectal, Appendiceal, or Peritoneal Mesothelioma Histologies

Ovarian Cancer Clinical Trial

Official title: Individualized Response Assessment to Heated Intraperitoneal Chemotherapy (HIPEC) for the Treatment of Peritoneal Carcinomatosis From Ovarian, Colorectal, Appendiceal, or Peritoneal Mesothelioma Histologies

Status Recruiting

Clinical Trial Summary

Background:

Cytoreductive surgery (CRS) removes tumors in the abdomen. HIPEC is heated chemotherapy that washes the abdomen. CRS and HIPEC may help people with peritoneal carcinomatosis. These are tumors that have spread to the lining of the abdomen from other cancers. Researchers think they can improve results of CRS and HIPEC by choosing the chemotherapy drugs used in HIPEC.

Objective:

To see if HIPEC after CRS can be improved, by testing different chemotherapy drugs, using a model called the SMART (Sample Microenvironment of Resected Metastatic Tumor) System.

Eligibility:

Adults ages 18 and older who have peritoneal carcinomatosis that cannot be fully removed safely with surgery.

Design:

Participants will be screened with:

Medical history

Physical exam

Blood and urine tests

Computed tomography (CAT) scan

Other imaging scans, as needed

Electrocardiogram (EKG)

Tumor biopsy, if needed

Laparoscopy. Small cuts will be made in the abdomen. A tube with a light and a camera will be used to see their organs.

Some screening tests will be repeated in the study.

Participants will enroll in NIH protocol #13C0176. This allows their tumor samples to be used in future research.

Participants will have CRS. As many of their visible tumors will be removed as possible. They will also have HIPEC. Two thin tubes will be put in their abdomen. They will get chemotherapy through one tube. It will be drained out through the other tube. They will be in the hospital for 7-21 days after surgery.

Participants will give tumor, blood, and fluid samples for research. They will complete surveys about their health and quality of life.

Participants will have follow-up visits over 5 years.

Clinical Trial Description

Background:

Peritoneal carcinomatosis is uniformly fatal if untreated; improved outcomes are seen with aggressive cytoreductive surgery (CRS) and heated intraperitoneal chemotherapy (HIPEC).

The selection of chemotherapeutic agent for HIPEC is largely based on primary tumor histology and provider preference as opposed to knowledge of the potential efficacy of a specific agent for an individual patient.

HIPEC is intended to target small or microscopic residual disease following complete cytoreduction; however, the actual efficacy and additional benefit of HIPEC is in question.

The SMART System provides an ideal platform upon which to perfuse small peritoneal tumor tissue implants and simulate HIPEC treatment ex vivo.

Tissue response to simulated ex vivo HIPEC treatment in the SMART System could inform chemotherapeutic agent selection for subsequent cytoreduction and intra-operative in vivo HIPEC treatments.

Objective:

To determine the correlation between ex vivo simulated HIPEC in the SMART System and in vivo HIPEC with respect to two measures of response to treatment: percent necrosis and Ki-67

Eligibility:

Histologically confirmed peritoneal carcinomatosis from appendiceal, colorectal, ovarian, or peritoneal mesothelioma histologies

Absence of extra-abdominal metastatic disease

Participant deemed able to undergo complete cytoreduction

Age >= 18 years of age

Design:

This is a Phase I study of cytoreductive surgery (CRS) and heated intraperitoneal chemotherapy (HIPEC), with randomization to one of two accepted HIPEC treatment regimens as determined by primary histology.

At the time of cytoreduction, representative peritoneal tumor biopsies will be obtained before and after intra-operative in vivo HIPEC treatment.

Tumor nodules harvested before intra-operative HIPEC will be placed in the SMART System, exposed to simulated ex vivo HIPEC treatment, and then perfused, with subsequent assessment of percent necrosis and Ki-67.

Tumor nodules harvested immediately after intra-operative HIPEC will be placed in the SMART System and perfused, with subsequent assessment of percent necrosis and Ki-67.

The correlation of percent necrosis and Ki-67 assessment following simulated ex vivo HIPEC and intra-operative in vivo HIPEC will be determined. ;
