Tomsk region is one of the areas with low population density, and the low level of transport accessibility of a number of settlements makes it difficult to organize oncological care. The analysis of posthumously recorded cases of registration of tumors of the central nervous system (CNS) and the search for reserves to reduce this indicator are of interest.
OBJECTIVE
To study the structure of the cohort of posthumously registered patients with primary tumors of the CNS and to evaluate the dynamics in 2011—2021 years.
MATERIAL AND METHODS
The analysis of cases of posthumously registered neuro-oncological pathology was performed using data from the population-based cancer registry of the Tomsk region for 2011—2021 yrs. and «BARS» medical information system.
RESULTS
A comparative analysis of morbidity and mortality in the Tomsk region and the Russian Federation revealed the absence of statistically significant dynamics. The increase of mortality rate from malignant neoplasms (MN) of the central nervous system in the Tomsk region against the background of a decline in this indicator in Russia as a whole, and a high rate of postmortem registration of neuro-oncological pathology compared to the MN of all localizations in the Tomsk region have been noted. There has been a growth in the proportion of postmortem registration of MN of the CNS with increasing age, thus more than a half of cases of neuro-oncological pathology in the 80 years and older age group were registered posthumously. The cerebral tumor caused sudden death in only one third of cases, with one in three patients diagnosed with CNS tumor during lifetime (organizational failure). In the remaining cases, the clinical symptoms and the anamnesis data allowed to suspect of the cerebral tumor before fatal outcome.
CONCLUSION
There is a decrease in the proportion of posthumously recorded cases of malignant neoplasms of the central nervous system in the Tomsk region in the dynamics. In two thirds of cases, postmortem registration of malignant neoplasms of the central nervous system in the population-based cancer registry of the Tomsk Region is due to the lack of adequate routing of patients with tumors of the central nervous system and low neuro-oncological alertness of the general health network’s doctors.
