ObjectivesThis study focuses on the evaluation of the effectiveness of radical gastrectomy with D2 node dissection after neoadjuvant therapy in the patients with gastric cancer. Gastric cancer is a widespread type of cancer, and it is the third leading cause of death in the cancer patients. Metastases most often occur in the lymph nodes and therefore, in addition to gastrectomy, lymph node dissection is often performed in the patients. We are distinguishing between D1, 2 and 3 dissections. As with other cancers, the effectiveness of neoadjuvant therapy is being considered, which aims to improve the patient's prognosis and thus the 5-year survival rate.MethodsWithin the study, we evaluated a group of the patients diagnosed with gastric cancer (n = 41). The average age of the patients was 62.3 years (20-72 years). 68.3 % (n = 28) patients underwent neoadjuvant therapy before surgery, the remaining 31.7 % (n = 13) underwent only radical gastrectomy with D2 lymphadenectomy. In all the cases, an open operational approach was implemented.ConclusionLymphadenopathy was found in 85.4 % of the patients. Complications occurred in both groups, but in the group with neoadjuvant therapy their share was lower (14.3 % vs 23.1 %), while in the group without neoadjuvant treatment the proportion of duodenal leaks was higher, as well as the number of reoperations. In total, an average of 30 ± 8 lymph nodes were harvested. A lower number of T3-4 cases was found in the neoadjuvant group (17.9 % vs 61.6 %), confirming that the tumour size was significantly smaller in the neoadjuvant group than in the group, who did not undergo it and underwent only surgical treatment. Relapse was found in 29.3 % of the patients after neoadjuvant treatment and in 38.5 % of the patients without neoadjuvant treatment. Also, mortality due to relapse was higher in the group without neoadjuvant treatment (30.8 % vs 21.7 %). The average survival was 25 months (Tab. 3, Fig. 3, Ref. 60).
