RESUMO
RESUMO: Objetivo: Descrever o perfil dos pacientes que referiram diagnóstico médico de câncer e descrever os tipos de câncer mais prevalentes, segundo variáveis selecionadas. Métodos: Estudo descritivo que utilizou dados da Pesquisa Nacional de Saúde (PSN) de 2013 para estimar prevalências e respectivos valores do intervalo de confiança (IC95%). Resultados: Menos de 2% dos adultos referiram diagnóstico médico de câncer, sendo mais relatado por mulheres, por pessoas com mais de 60 anos, entre brancos, em residentes da zona urbana e moradores da Região Sul. O câncer de próstata foi o mais referido entre os homens; entre as mulheres, o câncer de mama foi o mais prevalente. A menor idade média do primeiro diagnóstico foi identificada para câncer de colo de útero (35,4 anos; IC95% 30,3 - 40,6), e a maior, para câncer de próstata (65,7 anos; IC95% 64,2 - 67,0). Conclusão: Os achados deste estudo são importantes para o planejamento dos serviços de saúde e do seu acesso, pois revelam diferenças, principalmente regionais.
ABSTRACT: Objective: To describe the profile of patients who reported a medical diagnosis of cancer and describe the most prevalent types of cancer, according to selected variables. Methods: A descriptive study that used data from the National Survey of Health, 2013, to estimate prevalence and their values of confidence interval (95%CI). Results: Less than 2% of adults reported a medical diagnosis of cancer, with most reported by women, people over 60, among whites, residents in the village and residents of South Prostate cancer was the most reported among men and breast among women. The lowest average age of first diagnosis was identified for cervical cancer (35.4 years; 95%CI 30.3 - 40.6) and the highest for prostate (65.7 years; 95%CI 64.2 - 67.0). Conclusion: The findings of this study are important for the planning of health services and access, as they show differences mainly regional.

It is well known that the risk of development of gastric cancer (GC) in Helicobacter pylori-infected patients depends on several factors. Thus, the aim of this study was to investigate the effect of proinflammatory cytokine gene polymorphisms for IL-1β, IL-1RN and TNF-α on the development of GC in a Brazilian population. A total of 202 biopsies obtained from Brazilian patients with chronic gastritis and GC were included in the study. Infection with H. pylori cagA+ was determined by the polymerase chain reaction (PCR) as previously described. IL-1β, IL-1RN and TNF-α polymorphism genotyping was performed by restriction fragment length polymorphism PCR. Associations between gene polymorphisms, clinical diseases and virulence markers were evaluated using either the χ² test or the Fisher exact test. Our results demonstrated that the IL-1β -511 C/C and IL-1β -511 C/T alleles were associated with chronic gastritis in H. pylori-positive patients (P = 0.04 and P = 0.05, respectively) and the IL-1β -511 C/C genotype was associated with GC (P = 0.03). The frequency of IL-1RN alleles from patients with chronic gastritis and GC indicated that there was no difference between the genotypes of the groups studied. Similar results were found for TNF-α -308 gene polymorphisms. Our results indicate that the IL-1β -511 C/C and C/T gene polymorphisms are associated with chronic gastritis and GC development in H. pylori-infected individuals.

Background: There is an association of interleukin (IL)1B polymorphism with gastric cancer risk. However systematic reviews of the existing evidence have shown that such association varies across populations with different genetic ancestry. Aim: To evaluate the association of IL-1B-511 and IL-1RN polymorphism and Helicobacter pylori IgG antibodies CagA, with gastric cancer in two Colombian cities located in a high risk area for gastric cancer. Material and Methods: A case-control study including 46 gastric cancer cases and 99 controls with non-atrophic gastritis from a high risk zone for gastric cancer. Polymorphism genotyping was carried out by polymerase chain reaction (PCR) and IgG CagA status by ELISA. Results: IgG CagA seropositive individuals had an increased gastric cancer risk (odds ratio (OR) = 11.56; 95 percent confidence intervals (CI) 2.62-50.91 in Tunja and OR = 19.66, 95 percentCI 0.98-395 in Bogotá). IL-1B-511TT carriers in Tunja had increased risk of gastric cancer (OR = 11.31; 95 percentCI 1.20-106.54)), while IL-1RN*2 alelle carriers in Bogotá showed an inverse association with gastric cancer risk (OR = 0.03; 95 percentCI 0.01-0.65). Conclusions: This study adds evidence to the positive association of Helicobacter pylori CagA positive strains with non-cardial gastric cancer etiology. There is a possible heterogeneity in the association of IL-1B gene polymorphism with cancer, in populations of similar ethnic background and settled in the same risk area.
