THE REGIONAL FEATURES OF ONCOLOGICAL INCIDENCE IN CHILDREN OF THE TRANS-BAIKAL TERRITORY

Tumors in children are characterized by a high mortality rate. The data of oncological incidence in children are contradictory in different regions of the Russian Federation, it are published individual medical institutions or research groups.

Purpose of the study. To study the structure and the incidence of malignant neoplasms (MN) in children of the Trans-Baikal Territory aged 0 to 15 years for the period from 1996 to 2020.

Materials and methods of research. A retrospective and prospective analysis of the data of the regional pediatrics cancer registry for the period 1996-2020 were carried out. Statistical processing was performed using "Excel 2013". 

Results. The oncological incidence in children aged 0 to 15 years ranged from 7.5 to 14.5 per 100 000 children population for the period 1996 - 2020, for the prospective registration period (2006-2020) - from 9.3 to 20.4 per 100 000 children population. The incidence of the malignant neoplasms among children for the prospective period 2006-2020 was 14 per 100 thousands children population. In the first place among the malignant neoplasms is leukemia – 32,4 % (3,9 per 100 thousands children population), the second place is the neoplasms of the CNS – 20.8% (2,5 per 100 thousands children population), the third place is malignant lymphomas – 12% (1,4 per 100 thousands children population), the fourth place is the neuroblastoma 6,6% (1,0 per 100 thousands children population) and malignant neoplasms of the kidneys – 6,6% (0,8 per 100 thousands children population). Boys get sick with cancer more often than girls in a ratio of 1.27:1. 

Conclusions. The accumulation of oncological incidence in children for the very long period of time is required for the correct analysis of epidemiological data. The structure of malignant neoplasms in childhood in the Trans-Baikal Territory corresponds to Russian and world data.
