Analysis of archive material of patients with salivary gland neoplasms according to the department of o.o. bogomolets national medical university for the last five years

Abstract

Introduction: The frequency of salivary gland tumours remains high enough to date from 1% to 5% of all human tumours. Among benign tumours, pleomorphic adenomas dominate from 61% to 90%, and among malignant tumours, adenocarcinomas – 20%. Objectives: The purpose of our research was to evaluate an analysis of archive material of patients with neoplasms of the salivary glands that were treated at the department of O.O. Bogomolets National Medical University in the last five years. Material and methods: The material for the survey were archival histories of 232 patients with neoplasms of the salivary glands. The average age of patients was 50 ± 15.3 years. All patients underwent general clinical examinations. All patients were given a typical surgical intervention – excisional biopsy, partial, subtotal, or total parotidectomy. Postoperative material passed the pathohistological study. Results: Analysis of archival histories of patients with neoplasms of the salivary glands in the period 2014­2018 shows that most of the pathohistological diagnoses were: pleomorphic adenomas 133 (57.32%), adenocarcinomas 48 (20.68%), and adenolymphomas (Warthin tumour) 33 (14.22%). The analysis of data on the distribution of patients by type of malignant tumours of the salivary glands showed that the largest number of patients was with mucoepidermoid cancer and acinic cell adenocarcinoma in 16 (33.33%) and 12 (25%) patients, respectively. Conclusions: In this article we discussed most of the statistics associated with salivary gland neoplasms, such as frequency of salivary gland tumours (benign and malignant), distribution of patients by gender and age, localisation of pathological process, non­coincidence of clinical and pathological diagnoses, histological types of pleomorphic adenomas, and their distribution depending on age and gender.
