Stomach cancer is recognized as the third leading cause of death of cancer patients worldwide. Despite the radical treatment carried out, the progression of gastric cancer occurs in 30-40% of patients. The most common type of tumor progression of this localization is peritoneal carcinomatosis. When peritoneal carcinomatosis occurs, the median survival of patients does not exceed 3 months, the overall survival is no more than 6 months. Unfortunately, when peritoneal carcinomatosis occurs, palliative chemotherapy remains the only treatment option. The modern strategy for the prevention and treatment of peritoneal carcinomatosis is based on the concept of regional chemotherapy. The main methods of regional chemotherapy are hyperthermic intraperitoneal chemotherapy (HIPEC) and Pressured Intraperitoneal Aerosol Chemotherapy (PIPAC). PIPAC is a new technology for delivering chemotherapy drugs to tumor nodes on the surface of the peritoneum and allows the cytostatic to be evenly distributed over the abdominal cavity, increasing the depth of its penetration into tumor nodes due to the properties of aerosol and gradients of intra-abdominal and interstitial pressure. The method has a number of advantages over the HIPEC method: a large penetration depth of drugs, low trauma, the possibility of repeated use. We offer PIPAC for patients with locally advanced gastric cancer and a high risk of developing peritoneal carcinomatosis in an adjuvant mode in addition to standard treatment to prevent the development of carcinomatosis.


The study is interventional: patients over 18 years of age with an established diagnosis of stomach cancer (c)T3-4N0-3M0 CYT- will be randomized into 2 groups using the envelope method. The control group will receive only neoadjuvant chemotherapy + gastrectomy/ distal subtotal resection with D2 lymph node dissection, the active comparison group - neoadjuvant chemotherapy + gastrectomy with D2 lymph node dissection + PIPAC (Cisplatin (7.5 mg / m) + Doxirubicin 1.5 mg / m2)). Will be assessed: overall survival, median survival, disease-free survival, quality of life of patients.
