Resumo: | Whether age is an independent prognostic factor in breast cancer is a matter of debate. This is a retrospective cohort study of 767 breast cancer patients, stages I-III, treated at the Hospital das Clínicas, Minas Gerais Federal University, Belo Horizonte, Minas Gerais State, Brazil, from 2001 to 2008, aiming to study the relationship between age and survival. We included variables related to patients, tumors, and types of treatment. Different sets of Cox models were used for survival analysis. Hazard ratios (HR) and 95%CI were calculated. The relationship between age and breast cancer survival did not change substantially in any of them. In the model that accounted for all variables, women aged 70 and older (HR = 1.51, 95%CI: 1.04-2.18), and 35 or younger (HR = 1.78, 95%CI: 1.05-3.01) had shorter cancer specific survival than patients aged between 36 and 69. In addition, older age, having at least one comorbidity, and being white were associated with a higher risk of dying from other causes. In conclusion, shorter breast cancer survival is expected among the youngest and oldest patients. |

Se realizó sobre una cohorte retrospectiva de 767 pacientes con cáncer de mama, etapas I-III, atendidas en el Hospital de Clínicas, Universidad Federal de Minas Gerais, Belo Horizonte, Minas Gerais, Brasil, entre 2001 y 2008, para estudiar la relación entre edad y supervivencia. Incluimos variables relacionadas con las pacientes, los tumores y el tratamiento. Se construyeron diferentes conjuntos de modelos de Cox. Se calcularon los cocientes de riesgo (CR) e IC95%. La relación entre edad y supervivencia del cáncer de mama no ha cambiado substancialmente en los modelos. En el modelo con todas las variables, las mujeres de 70 años o más (CR = 1,51; IC95%: 1,04-2,18) y 35 años o menos (CR = 1,78; IC95%: 1,05-3,01) tuvieron menor supervivencia por cáncer de mama que las de 36 a 69 años. Tener edad avanzada, al menos una comorbilidad, y ser de piel blanca se asociaron a un mayor riesgo de morir por otras causas. En conclusión, las mujeres más jóvenes y las mayores parecen tener menor supervivencia de cáncer de mama.É discutível se idade é um fator prognóstico independente para câncer de mama.

Incluímos variáveis relacionadas às pacientes, aos tumores e ao tratamento. Diferentes conjuntos de modelos de Cox foram construídos. As razões de risco (RR) e IC95% foram calculados. A relação entre idade e sobrevida por câncer de mama não foi alterada substancialmente entre os modelos de Cox. No modelo com todas as variáveis explicativas, as mulheres de 70 anos ou mais (RR = 1,51; IC95%: 1,04-2,18) e até 35 anos (RR = 1,78; IC95%: 1,05-3,01) tiveram sobrevida causa-específica mais curta que as de 36-69 anos. Idades a partir de 70 anos, ter ao menos uma comorbidade e ser branca foram associadas a risco maior de óbito por outras causas. Em conclusão, as pacientes mais jovens e as mais idosas parecem ter sobrevida mais curta por câncer de mama.Reports in Public HealthCadernos de Saúde Pública2015-08-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersiontext/htmlapplication/pdfhttps://cadernos.ensp.fiocruz.br/ojs/index.php/csp/article/view/5901Reports in Public Health; Vol. 31 No. 8 (2015): AugustCadernos de Saúde Pública; v. 31 n. 8 (2015): Agosto1678-44640102-311Xreponame:Cadernos de Saúde Públicainstname:Fundação Oswaldo Cruz (FIOCRUZ)instacron:FIOCRUZenghttps://cadernos.ensp.fiocruz.br/ojs/index.php/csp/article/view/5901/12363https://cadernos.ensp.fiocruz.br/ojs/index.php/csp/article/view/5901/12364Débora BalabramCassio M.
