Cancer incidence in indigenous populations of Western Amazon, Brazil.

Objectives: This study aims to estimate a population-based cancer incidence among indigenous populations in the State of Acre, Brazilian Western Amazon, to provide knowledge about cancer epidemiological profiles contributing to healthcare policies and service planning. Although cancer epidemiology in Brazil is well described through incidence and mortality estimate in the general population, cancer estimates among indigenous peoples are still unknown.

Design: This is a descriptive study of cancer incidence among the indigenous population (2000-2012) in the State of Acre, Brazil.

Gene-Environment Interaction between Arg72Pro SNP and Selected Environmental Exposures among Brazilian Women Diagnosed with Benign Breast Disease.

Background: Benign breast disease (BBD) is a factor strongly associated with breast cancer worldwide. Arg72Pro SNP association with breast cancer is controversial due to the suggestion that environmental factors are required to modulate such risk. There are no studies evaluating these environmental interactions of the aforementioned SNP within BBD.

Thyroid cancer in Brazil: a descriptive study of cases held on hospital-based cancer registries, 2000-2016.

Objective To describe the clinical and epidemiological profile of primary thyroid cancer hospital cases in Brazil. Methods This is a descriptive study of cases held on hospital cancer records who had their first consultation for treatment in the period 2000-2016 and who were monitored by the hospitals providing those records. Results Of the 52,912 cases, 83.

Differentiated thyroid carcinoma: a 5-years survival study at a referral hospital in Brazil.

Background: Although the prognosis of differentiated thyroid carcinoma (DTC) therapy is considered excellent over time, some cases have a poorer prognosis and evolve into death.

Objective: This study aimed to estimate the 5-year specific survival and to identify prognosis factors in a cohort of DTC adult subjects.

Methods: Survival probability was estimated by Kaplan-Meier's method in a retrospective hospital-based cohort study.

Occupational exposure to pesticides and hematological alterations: A survey of farm residents in the South of Brazil.

This study sought to investigate the association of exposure to organochlorine (OC) and non-persistent pesticides with hematological parameters in an agricultural population in Southern Brazil. A cross-sectional study was conducted with a random sample of 275 farm workers and their families in Farroupilha-RS. A questionnaire was used to collect information on sociodemographic and lifestyle factors, duration, frequency and type of pesticide used, among others.
