Epidemiological aspects of morbidity and mortality from cervical cancer in Kazakhstan.

Epidemiological studies of cancer incidence in Kazakhstan have revealed an uneven distribution for cervical cancer. Incidence and mortality rates were calculated for different regions of the republic, including the two major cities of Almaty and Astana, in 1999-2008. Defined levels for cartograms for incidence were low (up to 12.8/100,000), medium (12.8 to 15.9) and high (above 15.9) and for mortality were up to 7.1, 7.1 to 10.8 and above 10.8, respectively. Basically high incidence rates were identified in the eastern, central and northern parts of the country and in Almaty. Such difference in cervical cancer data, and also variation in mortality/incidence ratios from a low of 0.4 in Almaty to a high of 0.71 in Zhambyl, point to variation in demographic and medical features which impact on risk and prognistic factors for cervical cancer in the country. Further research is necessary to highlight areas for emphasis in cancer control programs for this important cancer.
