NCT06295094

Brief Summary

The goal of this randomized clinical trial is to investigate whether pressurized intraperitoneal chemotherapy (PIPAC), delivered immediately after minimally invasive D2 gastrectomy and repeated 6-8 weeks later, improves 12-month peritoneal disease-free survival in patients with high-risk gastric adenocarcinoma when compared to standard treatment.

Study Arms (2)

Pressurized intraperitoneal chemotherapy (PIPAC)

EXPERIMENTAL

In the intervention arm, conventional pressurized intraperitoneal chemotherapy (PIPAC) with cisplatin (10.5 mg/m2 body surface in 150ml saline) and doxorubicin (2.1 mg/m2 body surface in 50ml saline) is performed through Medical Device Regulation (MDR) class IIb the CE-certified nebuliser by certified PIPAC surgeons directly after the completion of the minimally invasive gastric resection and reconstruction using the remaining relevant ports. Chemotherapy is administered through a CE-certified nebulizer according to the manufacturer's manual and followed by 30 minutes of simple diffusion. The carbondioxide is evacuated through a closed system, and the abdominal wall is closed according to local surgical standards. The same procedure is repeated, incorporating the same compounds and dose regimens six to eight weeks postoperatively and before the start of the adjuvant part of the perioperative systemic chemotherapy.
