Abstract

Nowadays, the technique of intra-arterial chemotherapy in primary patients with gastric cancer can be considered as an effective, low-toxic method of treatment. Preoperative intra-arterial chemotherapy may be the method of choice for improving the survival and quality of life of patients with gastric cancer.

Nowadays, results of the diagnosis and treatment of gastric cancer (GC) are still unsatisfactory. With the development of modern catheters and angiographic devices, regional chemotherapy in patients with gastric cancer has become more often used in clinical practice.

Goal of the research: Improving the response to treatment of patients with gastric cancer using regional intra-arterial chemotherapy (RIAC).

Materials and methods: There were analyzed short and long-term results of combination therapy of 110 patients with gastric cancer for the period of 2005-2020. The average age of patients was 59.2 ± 4.3 years old. The incidence of neoplastic process according to the TNM classification was as follows: T3N0M0 - 37 (33.63%) patients, T3N1M0 - 41 (37.27%) patients and T3N2M0 - 32 (29.1%) patients. Histologically, various forms of adenocarcinoma were diagnosed in all patients

All patients underwent the first stage of neoadjuvant intra-arterial chemotherapy (RIAC) according to the DPF scheme (Docetaxel 75mg/m2 + Cisplatin 75mg/m2 + Fluorouracil 1000mg/m2 on the 1st day), it comprised 2 cycles with an interval of 28 days, and then, there was performed surgery.

Results and their discussion: Short-term results of RIAC showed the effectiveness of treatment after 2 cycles of neoadjuvant intra-arterial regional chemotherapy; 93 (84.5%) patients showed partial regression, 17 (15.5%) patients showed stabilization of the process. These patients underwent radical surgery with the second stage of combination therapy - extended gastrectomy with D2 lymphodissection.
