Component Analysis of Laryngeal Cancer Incidence Dynamics in Kazakhstan from 1999 to 2014.

Background: In this study, we examined epidemiological aspects of dynamic changes in incidences of laryngeal cancer in male and female populations in Kazakhstan.

Materials And Methods: Primary data were for registered patients with malignant laryngeal tumors in the whole country during the period of 1999-2014. Evaluation of changes in laryngeal cancer incidence in the population of Kazakhstan was performed using component analysis.

Epidemiological assessment of leukemia in Kazakhstan, 2003- 2012.

Cancer is a major health problem facing the entire world, and Kazakhstan is not the exception. The aim of this study was to present an epidemiological assessment of leukemia in the population of Kazakhstan during 2003-2012. This descriptive and retrospective study was based on data obtained from all oncological organizations of the whole country.

Laryngeal cancer in Kazakhstan - ethnic, age and gender differences over time.

The purpose of the present study was to provide an assessment of the incidence of cancer of the larynx in Kazakhstan with especial attention to ethnicity and gender, as well as age. The retrospective design covered all new cases of laryngeal cancer in 11 years (1999-2009). The total number was 4,967 cases, 4,535 (91.

Malignant tumours of the central nervous system in Kazakhstan--incidence trends from 2004-2011.

In the article were observed the epidemiological aspects of malignant tumors of the central nervous system (MT CNS) in Kazakhstan in a retrospective study for the years 2004-2011. The material of the study was consolidated accounting data of oncology centers on patients with MT CNS (C70-72) with first time established diagnosis. Calculated were crude, age, standardized (world standard), aligned and predicted incidence of MT CNS among both male and female populations.

Epidemiological evaluation of laryngeal cancer incidence in Kazakhstan for the years 1999-2009.

The purpose was to provide a descriptive epidemiological assessment of the incidence of cancer of the larynx in Kazakhstan and spatial evaluation with gender characteristics. This retrospective study covered all new cases of laryngeal cancer in 11 years (1999-2009). The total number was 4,967 cases, 4,535 (91.

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.

Epidemiological evaluation of breast cancer in ecological areas of Kazakhstan--association with pollution emissions.

The aim of the research was to evaluate the incidence of breast cancer in the ecological areas of Kazakhstan and assess the potential . A retrospective study of 11 years (1999 to 2009) was conducted using descriptive and analytical methods. The incidence of breast cancer was the lowest in the Aral-Syr Darya area (18.

Epidemiology of esophageal cancer in Kazakhstan.

The incidence of esophageal cancer in Kazakhstan was analysed for the period of 1989-2010 years, with a focus on trends by age, gender and region. The highest rates of incidence were evident in the Western regions. The dynamics for cancer of the esophagus in the Republic demonstrated decrease, except in the Karaganda region, where a tendency for increase was noted.

Trends of prevalent cancer incidences in the Aral-Syr Darya ecological area of Kazakhstan.

The aim of this research was to examine the incidence of major forms of cancer in the Aral-Syr Darya ecological area of Kazakhstan. The present retrospective study of 11 years (1999-2009) was therefore conducted using descriptive and analytical methods. Incidence rates (crude and standardized) of 11 leading cancer sites were calculated and trends determined.

Age characteristics of incidences of prevalent cancers in the Aral Sea area of Kazakhstan.

The aim of the research was to examine age-specific features of incidence of cancer of the esophagus, lung, stomach, breast, cervix and thyroid gland in the Aral Sea area in Kazakhstan. A retrospective study of 11 years (1999-2009) was conducted using descriptive and analytical methods with calculated age incidence rates. The average age of patients with esophageal cancer and lung cancer had a tendency for increase with "aging", while in other cases "juvenation" was noted.
