The epidemiological features of the cervical cancer (CC) incidence and its spatial and temporal assessment in Kazakhstan were studied. Methods: The retrospective study was done for the period 2009-2018. Descriptive and analytical methods of oncoepidemiology were used. Results: During the study period, 16,441 new cases of CC were registered. The average annual crude and age-standardized incidence rate were 18.6±0.5 and 17.7±0.4 cases per 100,000 population of female, respectively, and their trends tended to increase (Tup=+2.3%; R2=0.708 and Tup=+1.9%; R2=0.615, respectively). The analysis of ASIR showed unimodal growth with a peak at 50-54 years – 45.3±1.1 cases per 100,000 population of female. Trends of ASIR decreased up to 30 years (Tdown=−1.8%; R2=0.111) and 35-59 years (Tdown=−0.9%; R2=0.103), in other age groups the trends increased, and were most pronounced in 40-44 (Tup=+4.1%; R2=0.878) and 65-69 years (Tup=+4.4%; R2=0.537). Trends in ASR of CC tended to grow in almost all regions, with higher levels in Mangystau (Tup=+4.1%; R2=0.482) and Aktobe (Tup=+6.3%; R2=0.846) regions. The cartograms of ASR per 100,000 population of female were allocated according to the following criteria: low – up to 16.3, average – from 16.3 to 19.2, high – above 19.2. The results of the spatial analysis showed the regions with a higher levels of CC incidence rate per 100,000 population of female: East Kazakhstan (19.8), Aktobe (20.0), Almaty (20.1), Kostanay region (20.9), Atyrau (21.7) regions and Almaty city (22.0). Conclusion: The study of trends of the cervical cancer incidence has the theoretical and practical value: monitoring and evaluation of screening programmes, which are implemented in the country, and conduction of secondary prevention of cervical pathology. Health authorities should consider the obtained results in the in the organization of anti-cancer activities.
