SURGICAL TREATMENT OF GASTRIC CARCINOMA IN THE UNIVERSITY HOSPITAL OF SPLIT - A 3-YEAR RETROSPECTIVE STUDY

Abstract

Objective: The aim of this study was to analyse the pathohistological features of gastric adenocarcinoma and short-term clinical outcomes in patients operated in the period from 1 January 2018 to 1 August 2020.

Materials and methods: This retrospective study included patients operated on for gastric adenocarcinoma in the period from 1 January 2018 to 1 August 2020. The following data were collected from the archive of disease history and path histological findings: age, sex, tumour localization, TNM stage, grade, histological type, lymph node status, length of hospitalization, type of surgery.

Results: Of the total number of patients, 36 (65%) were male, and 19 (35%) were female. People over 63 make up 75% of the
total number of patients. The most common pathological stage is IIIA (20%), and the mean distance of the tumour from the edge is 5.00 cm. The median number of removed lymph nodes is 6.50. The mean value of positive lymph nodes is 3.00. The mean value of positive lymph nodes in high-grade tumours was 9.86, and in low-grade tumours 2.32. However, there is no statistically significant association, P=0.276. The most common type of surgery was subtotal gastrectomy. Complications were found in 29.09%, and the need for revision was found in 9.09% patients. Not a single observed patient died immediately after the operation. The mean length
of hospitalization in patients with complications was 9 days longer than in patients without complications.

Conclusions: Demographic and pathohistological determinants of gastric adenocarcinoma do not differ from other studies. The length of the resection margins is in accordance with the guidelines. The average number of removed lymph nodes is less than recommended. Histological grade is associated with a higher number of positive lymph nodes, but the association is not statistically
significant.
