Qualidade de vida em pacientes sobreviventes de câncer de mama comparada à de mulheres saudáveis Quality of file in breast cancer survivors compared to healthy women
Abstract
OBJETIVOS: Avaliar a qualidade de vida em mulheres sobreviventes de câncer de mama e comparar com mulheres saudáveis pareadas por idade. MÉTODOS: Estudo transversal com uma amostra de 199 pacientes sobreviventes de câncer de mama, incluídas consecutivamente um ano ou mais após o diagnóstico. As pacientes haviam sido tratadas em dois grandes hospitais. Essas pacientes foram comparadas com um grupo de mulheres saudáveis, pareadas por idade com as pacientes, composto por funcionárias e voluntárias dos dois hospitais. A avaliação da qualidade de vida foi realizada através do World Health Organization Quality of Life Questionnaire, version bref (WHOQOL-bref), e foram obtidos dados socioeconômicos, clínicos e do tratamento. Os testes estatísticos utilizados foram do χ² e modelo linear generalizado. Foi adotado o nível de significância de 5%. RESULTADOS: As sobreviventes de câncer de mama tinham média de idade de 54,4 anos (DP=10,4) e tempo médio de diagnóstico de 5,0 anos (DP=4,6). As pacientes sobreviventes relataram piores avaliações de qualidade de vida geral (pPURPOSES: To assess the quality of life of breast cancer survivors compared to a sample of age-matched healthy women. METHODS: A cross-sectional design was conducted on 199 consecutive breast cancer survivors, one year or more after diagnosis, treated at two large hospitals. The patients were compared to age-matched healthy women consisting of employees and volunteers of the two hospitals. Quality of life was evaluated using the World Health Organization Quality of Life Questionnaire, version Bref (WHOQOL-bref) and socioeconomic, clinical, and treatment data were obtained. The χ² test and a generalized linear model were used for statistical analysis. The adopted level of significance was 5%. RESULTS: The mean age of breast cancer survivors was 54.4 years (SD=10.4) and the average length of time since diagnosis was 5.0 years (SD=4.6). The survivors reported a poorer overall quality of life (p=0.001), and for the physical (p<0.001), psychological (p=0.002) and environment (p=0.029) domains than the comparison group, after adjusting for potential confounders. There was no significant difference in the social relationships domain (p=0.929) between groups. CONCLUSION: The results suggest that many breast cancer survivors experienced worse quality of life assessment than healthy women. This information may be useful to establish strategies to improve the quality of life of women with breast cancer.
