Brief summary: 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.

Detailed description: This study is an exploratory analysis of the utility of ctDNA as a sensitive biomarker in patients with Peritoneal Carcinomatosis treated with chemotherapy, CRS and/or hyperthermic intraperitoneal chemotherapy (HIPEC).

OBJECTIVES:

I. To measure changes in circulating tumor deoxyribonucleic acid (ctDNA) in patients with peritoneal carcinomatosis (PC) from gastrointestinal (GI) cancers who are candidates for cytoreductive surgery (CRS) with or without hyperthermic intraperitoneal chemotherapy (HIPEC).

II. To determine the percentage of patients on protocol with undetectable ctDNA (clearance rate) after complete CRS.

III. To identify any associations between clinical staging of CRS and measurable ctDNA.

IV. To assess changes in ctDNA levels in response to chemotherapy in patients with PC.

V. To guide treatment based on ctDNA response.

OUTLINE:

Patients may receive induction chemotherapy at the discretion of the treating physician for up to 6 months. Patients undergo blood sample collection for ctDNA analysis at baseline, post chemotherapy/pre-surgery, 3-4 weeks post CRS/HIPEC, then every 3 months over 2 years. Patients also undergo tissue collection before or during surgery and their medical records are reviewed.

Eligibility criteria: Inclusion Criteria:

* Patients with histologically confirmed carcinoma of presumed gastrointestinal origin (gastric, esophageal, colorectal, appendiceal, hepatobiliary or peritoneal carcinomatosis of apparent GI primary) with documented diffuse peritoneal carcinomatosis, either by conventional imaging studies, positive ascitic fluid analysis, or surgical staging
* Measurable or evaluable disease by cross-sectional imaging studies
* Patients must be candidates for possible surgical cytoreduction (with or without HIPEC) as determined by a study surgical oncologist
* Age \>= 18 years
* Estimated life expectancy of at least 12 months
* Eastern Cooperative Oncology Group (ECOG) performance status =\< 2
* Patients must sign informed consent
* Be willing to present for medical exams, blood draws and imaging as scheduled in protocol
* Be able to donate two 10 mL tubes of blood every 3 months
* Women of childbearing potential will undergo routine screening evaluation for pregnancy prior to enrollment and be managed per standard of care

Exclusion Criteria:

* Patients without a confirmed pathologic diagnosis of carcinoma
* Second uncontrolled primary malignancy
* Patients who are pregnant
* Patients who cannot undergo a therapeutic surgical cytoreduction
* Bone marrow transplant or other organ transplant recipient
* Any unstable, serious co-existing medical conditions including but not limited to myocardial infarction, coronary bypass surgery, unstable angina, cardiac arrhythmias, clinically evident congestive heart failure, or cerebrovascular accident within 6 months prior to screening
* Patients with cardiovascular or pulmonary risk factors contributing to high risk for surgical complications, at the discretion of the surgeon
* Serious concomitant systemic disorder that would compromise the safety of the patient or compromise the patient's ability to complete the study, at the discretion of the investigator
