About
Gastric cancer is the fifth most common cancer worldwide and the third leading cause of cancer-related mortality. In patients with locally advanced gastric cancer, multimodal treatment strategies, including perioperative chemotherapy, have significantly improved survival rates. Despite these advances, peritoneal carcinomatosis (PC) remains a serious problem, occurring in 60% of cases after radical surgery. PC is associated with poor prognosis and limited treatment options.
Intra-abdominal chemotherapy, particularly hyperthermic intraperitoneal chemoperfusion (HIPEC), has demonstrated advantages in the treatment of PC. However, a new technique, pressurized intraperitoneal aerosolized chemotherapy (PIPAC), is emerging as a promising alternative. PIPAC delivers chemotherapeutic agents directly to the peritoneal surface as an aerosol, allowing deeper penetration of drugs into tumor implants while minimizing toxicity and invasiveness.
This study hypothesizes that the addition of PIPAC as a preoperative treatment for patients with locally advanced gastric cancer may reduce the incidence of peritoneal carcinomatosis compared to standard therapy. The primary objective of this study is to determine whether preoperative PIPAC reduces the incidence of peritoneal carcinomatosis in these patients.
Full description
Gastric cancer is the fifth most common cancer globally and the third leading cause of cancer-related death. In patients with locally advanced gastric cancer, multimodal treatment strategies, including perioperative chemotherapy, have significantly improved survival outcomes. However, PC remains a major challenge, often occurring in 60% of cases after radical surgery, and is associated with a poor prognosis and limited treatment options.
Intra-abdominal chemotherapy, particularly HIPEC, has shown benefits in the treatment of PC. However, a newer method, PIPAC, is emerging as a promising alternative. PIPAC delivers chemotherapeutic agents directly to the peritoneal surface via aerosol, ensuring deeper penetration of the drugs into tumor implants and offering lower toxicity and less invasiveness compared to traditional methods.
This study hypothesizes that adding PIPAC as a preoperative treatment in patients with locally advanced gastric cancer may reduce the occurrence of peritoneal carcinomatosis compared to standard therapy alone. PIPAC will be applied before neoadjuvant chemotherapy to patients at high risk for peritoneal recurrence, with the goal of improving survival rates and reducing recurrence after surgery.
The main objectives of this study are to determine whether preoperative PIPAC reduces the incidence of peritoneal carcinomatosis in patients with locally advanced gastric cancer. Secondary objectives include assessing overall survival (OS), progression-free survival (PFS), disease-free survival (DFS), the occurrence of serious adverse events (SAEs), quality of life (QoL) as measured by the EORTC QLQ-C30, postoperative mortality (Clavien-Dindo classification), and pathological response (TRG) in comparison to patients receiving standard treatment.
