THE EFFECT OF CYTOREDUCTIVE SURGERY AND INTRAPERITONEAL HYPERTHERMIC CHEMOPERFUSION (HIPEC) ON THE CLINICAL OUTCOME OF TREATMENT OF PATIENTS WITH ADVANCED GASTRIC CANCER

Abstract

Introduction. For gastric cancer (GC), metastatic peritoneal carcinomatosis (PC) is a typical process. PC and its consequences usually lead to the death of 20-40 % of patients with GC. For carefully selected patients, intraperitoneal hyperthermic chemoperfusion may be considered. The aim of the study was to investigate the effect of cytoreductive surgery in combination with HIPEC on the clinical course of the postoperative period, the frequency of postoperative complications and side effects of chemotherapeutic drugs in the treatment of advanced GC. Materials and methods. The results of treatment of 34 patients with advanced GC were considered. The patients were divided into two groups: IA group — 24 patients with advanced GC, who first underwent complete primary cytoreductive surgery (CRS) with adjuvant chemotherapy (ACT) according to the FLOT scheme and IB group — 10 patients with advanced GC treated by CRS + ACT + HIPEC. Results. Comparing the number of patients with postoperative complications in groups IA (CRS + ACT) and IB (CRS + HIPEC + ACT) using the exact bilateral Fisher’s test p> 0. 05. Comparing the frequency of side effects of chemotherapeutic treatment in the FLOT mode in groups IA (CRS + ACT) and IB (CRS + HIPEC + ACT), the values ??of χ2 = 20. 750, χ2Cr = 28. 568 (p = 0. 0622) were obtained. Conclusions. The usage of HIPEC in combination with complete CRS and ACT is a promising method of treatment of this group of patients. As a result of this study, it was proved that there is no statistically significant effect on the clinical course of the postoperative period due to the increase in the frequency of postoperative complications or side effects of chemotherapeutic drugs.
