Summary
Brief summary (as posted)
This clinical trial collects biospecimen samples to create a personalized ctDNA test to guide treatment for patients with gastrointestinal cancer with peritoneal carcinomatosis. Deoxyribonucleic acid, or DNA, is the material that carries all the information about how a living thing will work and function. Everyone is born with the same DNA in all our cells throughout our body. Sometimes, some of the cells in the body develop abnormalities in the DNA that cause those cells to grow abnormally and uncontrollably. Cancer occurs when there is abnormal and uncontrolled growth of cells. The DNA in cancer cells is therefore different from the DNA someone is born with. The Signatera ctDNA assay is a laboratory test that takes tumor (cancer) tissue and evaluates it for unique tumor DNA. This evaluation is used to create a report (otherwise known as an assay) personalized to each person's cancer. The personalized assay creates a personalized blood test to detect the level of abnormal DNA from the cancer that may be circulating in the body. Once this personalized blood assay is designed, it may be used to monitor a person's blood for the presence of ctDNA, which will indicate the presence or absence of cancer over time, even after treatment.

Arms and outcomes
Arms (1)
- type
- EXPERIMENTAL
- label
- Diagnostic (biospecimen collection)
- description
- Patients will receive standard treatment with surgery, HIPEC, and chemotherapy as appropriate to the patient situation, extent of disease and multi-disciplinary evaluation. Patients undergo blood sample collection for ctDNA analysis at baseline, pre-surgery, post-surgery and every 3 months up to 2 years. Patients undergo tissue collection before or during surgery and their medical records are reviewed.

- Procedure: Biospecimen Collection - blood and tissue sample collection
- Other: Electronic Health Record Review
Primary outcomes (2)
- measure
- Clearance rate of circulating tumor deoxyribonucleic acid (ctDNA) with cytoreductive surgery (CRS)
- timeFrame
- Baseline, pre-surgery, 3- 4 weeks post-surgery and then every 3 months up to 2 years after cytoreductive surgery (CRS)
- description
- Will compare results with clinical staging of CRS (surgical staging, surgical outcomes, Peritoneal Carcinoma Index \[PCI\] and cytoreduction \[CC\] score). ctDNA clearance rate defined as the % of patients on our protocol with undetectable ctDNA. Will associate ctDNA changes with clinical response by Response Evaluation Criteria in Solid Tumors and surgical staging, surgical outcomes, PCI and CC score using standard T-testing, log-rank analysis or similar non-parametric testing.
