About this study

Official title: A Phase II Study of Robotic Cytoreduction and Hyperthermic Intraperitoneal Chemotherapy (HIPEC) for Patients With Gastric Cancer and Limited Peritoneal Metastasis: ROBO-CHIP Trial

This phase II clinical trial tests how well robotic cytoreduction and hyperthermic intraperitoneal chemotherapy (HIPEC) in treating patients with gastric cancer that has spread to the tissue that lines the wall of the abdominal cavity (peritoneum). Gastric cancer is the third leading cause of cancer related deaths worldwide and peritoneal metastasis are found in 30% of patients at time of diagnosis. Patients with peritoneal metastasis have poor survival rates. Traditional surgery is done with a large incision and has a high complication rate and longer hospital stays. Robot assisted (robotic) cytoreduction is a surgical option that uses small incisions and there is less risk of complications. HIPEC involves infusing heated chemotherapy into the abdominal cavity during surgery. Robotic cytoreduction together with HIPEC may improve recovery and decrease complications after surgery.

Being tested
Cisplatin, Computed Tomography, Gastrectomy, Magnetic Resonance Imaging, Positron Emission Tomography

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Hospital length of stay

    Recorded as number of days in hospital following surgery.

    Measured: Up to 30 days post-surgery

  2. 30 day readmission rate

    Assessed by the number of participants who are re-admitted to the hospital after being discharged post-surgery

    Measured: Up to 30 days post-surgery

  3. Adverse Events

    Assessed by Clavien-Dindo Classification (grade 1-5, grade 1 being least severe and grade 5 being death)

    Measured: Up to 30 days post surgery

Secondary outcomes (5)
  1. Operative time

    Recorded as the time from incision to close

    Measured: Intraoperative

  2. Opioid consumption

    Assessed by morphine milligram equivalents during hospitalization and post-surgical recovery.

    Measured: Up to 3 years

  3. Nursing reported pain scores

    As recorded (mean and max) during hospitalization and post-surgery follow-up visits

    Measured: Up to 3 years

  4. Recurrence-Free Survival (RFS)

    Assessed from the date of gastrectomy and hyperthermic intraperitoneal chemotherapy (HIPEC). Patterns of tumor recurrence will be assessed by reviewing routine surveillance imaging.

    Measured: Up to 3 years

  5. Overall Survival (OS)

    Defined as the time from gastrectomy and HIPEC until death due to any cause.

    Measured: Up to 3 years

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Cisplatin, Computed Tomography and Gastrectomy in people with Gastric Adenocarcinoma and Gastroesophageal Junction Adenocarcinoma, run by Mayo Clinic at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 18 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 8 Apr 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Clinical Trials Referral Office (855-776-0015, mayocliniccancerstudies@mayo.edu), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Hospital length of stay (time frame: Up to 30 days post-surgery). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 8 Apr 2026.
