Pressurized Intraperitoneal Aerosol Chemotherapy (PIPAC) and Systemic Chemotherapy as a First-line Treatment for Gastric Cancer Peritoneal Metastases: Open-label, Single-arm, Multi-center Feasibility Study

Not applicable Interventional Vilnius University · NCT05644249

This study is testing a new way to treat gastric cancer that has spread in the abdomen by combining a special type of aerosol chemotherapy with standard chemotherapy to see if it works better for patients.

What this trial studies

This study investigates the feasibility of combining pressurized intraperitoneal aerosol chemotherapy (PIPAC) with systemic FOLFOX chemotherapy for patients with gastric cancer and peritoneal carcinomatosis. The approach aims to enhance drug distribution and penetration by using aerosolized chemotherapy under increased pressure. A total of 37 participants will receive three cycles of systemic chemotherapy followed by PIPAC treatments, with evaluations conducted after the third PIPAC procedure to determine further treatment options. The study is open-label and will take place at two major cancer treatment centers in Lithuania.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with histologically verified HER2 negative gastric adenocarcinoma and peritoneal carcinomatosis who are eligible for first-line FOLFOX chemotherapy.

Not a fit: Patients with extra-abdominal metastases, certain types of gastroesophageal junction cancer, or those with mechanical bowel obstruction will not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could improve outcomes for patients with gastric cancer and peritoneal metastases by enhancing drug delivery and efficacy.

How similar studies have performed: While PIPAC has shown encouraging preliminary results, the combination with systemic chemotherapy is still investigational and has limited prior data.
