Analysis of the basic statistical indicators of malignant tumors of the oral cavity and pharynx in the Republic of Uzbekistan

Abstract

Abstract. Malignant tumors (MNs) in the population of Uzbekistan continue to be of a primary importance in clinical oncology, causing significant damage to the economy and social health [1, 4, 6]. Malignant neoplasms of the head and neck represent a heterogeneous group of tumors, with common tendencies towards the further spread and progression of the disease. Due to the variety of localizations of tumors and tissues from which tumors of the head and neck originate, the biology of tumor growth, the pathways of metastasis, tumor boundaries, signs and symptoms of the disease are fundamentally different. Risk factors for the onset of the disease include smoking and alcohol abuse. About 60% of cases of oral cavity and pharyngeal cancer are detected at stages III – IV due to the latent period at the initial stages of the disease. The clinical picture is due to the initial localization and direction of tumor growth [2, 5, 7, 9].

Key words: epidemiology, malignant neoplasms of the oral cavity and pharynx, statistics.
