Breast and cervical cancer screening practices in nine countries of Eastern Europe and Central Asia: A population-based survey.

Background: Eastern Europe and Central Asia (EECA) countries have higher cervical and breast cancer mortality rates and later stage at diagnosis compared with the rest of WHO European Region. The aim was to explore current early detection practices including "dispensarization" for breast and cervix cancer in the region.

Methods: A questionnaire survey on early detection practices for breast and cervix cancer was sent to collaborators in 11 countries, differentiating services in the primary health setting, and population-based programs.

Worldwide trends in esophageal cancer survival, by sub-site, morphology, and sex: an analysis of 696,974 adults diagnosed in 60 countries during 2000-2014 (CONCORD-3).

Background: Esophageal cancer survival is poor worldwide, though there is some variation. Differences in the distribution of anatomical sub-site and morphological sub-type may help explain international differences in survival for all esophageal cancers combined. We estimated survival by anatomic sub-site and morphological sub-type to understand further the impact of topography and morphology on international comparisons of esophageal cancer survival.

Global survival trends for brain tumors, by histology: analysis of individual records for 556,237 adults diagnosed in 59 countries during 2000-2014 (CONCORD-3).

Background: Survival is a key metric of the effectiveness of a health system in managing cancer. We set out to provide a comprehensive examination of worldwide variation and trends in survival from brain tumors in adults, by histology.

Methods: We analyzed individual data for adults (15-99 years) diagnosed with a brain tumor (ICD-O-3 topography code C71) during 2000-2014, regardless of tumor behavior.

Objective: To assess the incidence of neuroglial brain malignancies in 2000-2020 considering individual records of morphologically verified cases in the cancer registry of the Arkhangelsk region.

Material And Methods: We analyzed overall and age-adjusted incidence of neuroglial brain malignancies in 2000-2020 considering morphological subtypes of tumor.

Comparison of female breast cancer between Russia and Germany: A population-based study on time trends and stage at diagnosis.

Objectives: While a mammography-screening program (MSP) is being offered systematically in Germany since 2009, the dispanserizatsiya has been implemented in Russia since 2013. This study examined trends of stage at breast cancer diagnosis in two Russian regions and compared the results with the development in Germany. In addition, we aimed to gain further insights into the early detection of breast cancer in Russia.

World-wide trends in net survival from pancreatic cancer by morphological sub-type: An analysis of 1,258,329 adults diagnosed in 58 countries during 2000-2014 (CONCORD-3).

Background: Ductal adenocarcinomas and neuroendocrine tumours are the two main morphological sub-types of pancreatic cancer. Using data from CONCORD-3, we examined whether the distribution of morphological sub-types could help explain international variations in pancreatic cancer survival for all morphologies combined. We also examined world-wide survival trends from pancreatic cancer, by morphological sub-type and country.

Worldwide trends in population-based survival for children, adolescents, and young adults diagnosed with leukaemia, by subtype, during 2000-14 (CONCORD-3): analysis of individual data from 258 cancer registries in 61 countries.

Background: Leukaemias comprise a heterogenous group of haematological malignancies. In CONCORD-3, we analysed data for children (aged 0-14 years) and adults (aged 15-99 years) diagnosed with a haematological malignancy during 2000-14 in 61 countries. Here, we aimed to examine worldwide trends in survival from leukaemia, by age and morphology, in young patients (aged 0-24 years).

The histology of brain tumors for 67 331 children and 671 085 adults diagnosed in 60 countries during 2000-2014: a global, population-based study (CONCORD-3).

Background: Global variations in survival for brain tumors are very wide when all histological types are considered together. Appraisal of international differences should be informed by the distribution of histology, but little is known beyond Europe and North America.

Methods: The source for the analysis was the CONCORD database, a program of global surveillance of cancer survival trends, which includes the tumor records of individual patients from more than 300 population-based cancer registries.

[Age-related features of the dynamics of morbidity and mortality, localization and histological structures of rectal cancer (population study).].

Rectal cancer is a malignant tumor of the distal colon of epithelial origin. Every year, more than 30,000 (30 969 - 2018) new cases of Rectal cancer and 16,000 deaths (16 151) are registered in Russia. The index of reliability of accounting (the ratio of the number of dead to sick) is 0,52%.

Development and initial validation of the polyhandicap severity scale.

Objectives: Providing a new tool, based on the point of view of experts in polyhandicap, which assesses the global severity of the health status of polyhandicapped persons is necessary. We present herein the initial validation of the polyhandicap severity scale (PSS).

Methods: The initial development of the tool was undertaken in two steps: item selection and validation process.

Impact of severe polyhandicap cared for at home on French informal caregivers' burden: a cross-sectional study.

Objectives: Polyhandicap (PLH), defined by a combination of profound intellectual impairment and serious motor deficits, is a severe condition with complex disabilities. In France, care of the large majority of PLH individuals is managed in specialised rehabilitation centres or residential facilities, but some of PLH individuals are cared for at home. The aims of this study were to assess the self-perceived burden among informal caregivers of PLH individuals and to identify potential determinants of this burden.

Health issues in polyhandicapped patients according to age: Results of a large French cross-sectional study.

Introduction: A better understanding of the natural course of the health status of patients with polyhandicap may optimize preventive and curative care management. From a large sample of patients aged from 3 to 25 years, we reported the description of their health status.

Methods: This was an 18-month cross-sectional study including patients aged from 3 to 25 years with a combination of severe motor deficiency and profound intellectual impairment.

A cross-national perspective of migration and cancer: incidence of five major cancer types among resettlers from the former Soviet Union in Germany and ethnic Germans in Russia.
