Robotic Cytoreduction and Hyperthermic Intraperitoneal Chemotherapy for Treatment of Gastric Cancer With Limited Peritoneal Metastasis, ROBO-CHIP Study

April 2, 2026 updated by: Mayo Clinic

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.

Detailed Description

PRIMARY OBJECTIVE:

I. To assess short-term morbidity and disease-free survival outcomes for patients with gastric adenocarcinoma with limited low volume peritoneal metastasis and/or positive peritoneal cytology undergoing robotic cytoreduction and hyperthermic intraperitoneal chemotherapy.

SECONDARY OBJECTIVES:

I. To obtain a biorepository for additional translational research including:

Ia. Stool samples for shotgun metagenomic sequencing and metabolomic quantification of the fecal microbiome before and after gastrectomy; Ib. Blood and peritoneal tissue biobanked for future investigations; Ic. Patient reported outcomes using the Mayo Clinic Upper Digestive Disease Survey questionnaires at 1, 3, 6 and 12 months.

OUTLINE:

Patients undergo collection of stool and blood sample before and after surgery. Patients also undergo robotic gastrectomy and HIPEC with docetaxel and cisplatin on study. Patients undergo computed tomography (CT), magnetic resonance imaging (MRI), or positron emission tomography (PET)/CT scans throughout the trial.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Eligibility Criteria

Eligibility Criteria

Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.
