FIELD: medicine.
SUBSTANCE: invention relates to the field of medicine, in particular, to oncology. Proposed is a method for combined treatment of resectable locally advanced gastric cancer with peritoneal carcinomatosis. Surgical treatment is performed to the extent of palliative gastrectomy with peritonectomy and installing a peritoneal port system for postoperative intraperitoneal chemotherapy. Molecular genetic studies of tissues of tumour fragments and metastases are conducted by quantitative real-time PCR. The expression levels of the chemosensitivity genes RRM1, TOP1, TUBB3, TYMS, BRCA1, ERCC1, and ABCC5 are determined. 2 to 3 weeks after surgical treatment, if the condition of the patient is satisfactory, personalised post-operative systemic and intraperitoneal chemotherapy is performed until the toxicity is intolerable or the disease progresses.
EFFECT: invention improves the results of combined treatment of patients with locally advanced gastric cancer with peritoneal carcinomatosis.
