Breast and cervical cancer screening in the newly independent countries of the former Soviet Union is largely opportunistic, and the countries of the region have one of the highest rates of cervical cancer in the WHO European region.
study aims to compare the phased distribution and changes in the incidence of breast and cervical cancer in the newly independent countries of the former Soviet Union.
Researchers collected data on the incidence of breast and cervical cancer from 2008 to 2017 from official statistics from Armenia, Azerbaijan, Belarus, Georgia, Kazakhstan, Kyrgyzstan, the Republic of Moldova, the Russian Federation, Ukraine and Uzbekistan, and classified them by tumor, lymph nodes, metastasis (TNM) stage and the age of available population-based cancer registration data.
the incidence of age standardization using Log-linear regression varies over time.
The incidence of breast cancer in different countries was phased between 2013 and 2017, with more than 50 per cent of breast cancer cases in all the countries analysed, and more than 75 per cent of breast cancer cases in Belarus, Kazakhstan and Ukraine registered as phase I-II.
In the Republic of Moldova and Russia, the incidence of stage I breast cancer is higher in the screening age group (50-69 years) than in other age groups, but in Georgia and Ukraine the highest proportion is in the 15-49 age group.
the incidence of stage specificity of breast cancer increased over time, mostly stage I.
The incidence of cervical cancer in different countries is higher for cervical cancer, which is already advanced at the time of diagnosis (phase III-IV), particularly in Moldova and Armenia( 50 per cent).
of stage I cervical cancer in all countries decreased with age, while the proportion of advanced cervical cancer increased with age.
in 2008-17, the incidence of stage-specific cervical cancer generally increased.
that early screening for breast cancer has made some progress in the newly independent countries of the former Soviet Union.
