Gastric Cancer Peritoneal Metastasis Hipec First Line

ClinConnect Summary

This clinical trial is studying a new treatment approach for patients with advanced gastric cancer that has spread to the lining of the abdomen, known as peritoneal metastasis. Researchers want to see if combining a method called Hyperthermic Intraperitoneal Chemotherapy (HIPEC) with standard chemotherapy and an immunotherapy drug called sintilimab can improve treatment outcomes. HIPEC involves delivering heated chemotherapy directly into the abdominal cavity, which may help the drugs work better against the cancer.

To participate in this trial, patients must be between 18 and 75 years old, have a specific type of stomach cancer that cannot be surgically removed, and have not received any previous cancer treatments. Participants will need to provide blood and tissue samples and should expect to be monitored closely for safety and treatment effectiveness. It’s important to note that this trial is not yet recruiting participants, so those interested will need to wait for it to start. Overall, this trial aims to find a more effective treatment for a challenging condition that currently has limited options.
