Fatigue and quality of life in breast cancer survivors: a comparative study

Abstract

PURPOSE: To assess fatigue and quality of life in disease-free breast cancer survivors in relation to a sample of age-matched women with no cancer history and to explore the relationship between fatigue and quality of life. METHODS: A cross-sectional study was conducted in a sample of 202 consecutive disease-free Brazilian breast cancer survivors, all of whom had completed treatment, treated at 2 large hospitals. The patients were compared to age-matched women with no cancer history attending a primary health care center. The Piper Fatigue Scale-Revised and the World Health Organization Quality of Life Instrument (WHOQOL-BREF) were used to measure the fatigue and quality of life, respectively. Socio-demographic and clinical variables were also obtained. The χ 2 test, generalized linear model, and Spearman correlation coefficient were used for statistical purposes. The adopted level of significance was 5%. RESULTS: Breast cancer survivors experienced significantly greater total and subscale fatigue scores than comparison group (all p-values<0.05). In addition, survivors reported a poorer quality of life in physical (p=0.002), psychological (p=0.03), and social relationships (p=0.03) domains than comparison group. No difference was found for the environmental domain (p=0.08) for both groups. For survivors of breast cancer and for comparison group, the total and subscale fatigue scores were related to lower quality of life (all p-values<0.01). CONCLUSION: The findings of this study highlight the importance of assessing fatigue and quality of life in breast cancer survivors. ResumoOBJETIVO: Avaliar a fadiga e a qualidade de vida de sobreviventes de câncer de mama, livres da doença, em relação a uma amostra de mulheres da mesma idade, sem histórico de câncer, e explorar a relação entre fadiga e qualidade de vida. MÉTODOS: Estudo transversal realizado com uma amostra consecutiva de 202 pacientes brasileiras, sobreviventes de câncer de mama e livres da doença, que haviam completado o tratamento em 2 grandes hospitais. As pacientes foram comparadas com mulheres da mesma idade, sem história de câncer, acompanhadas em uma Unidade Básica de Saúde. A Escala de Fadiga de Piper-Revisada e o World Health Organization Quality of Life Instrument (WHOQOL-BREF) foram usados para avaliar a fadiga e a qualidade de vida, respectivamente. Dados sociodemográficos e clínicos também foram obtidos. O teste do χ 2 , modelo linear generalizado e coeficiente de correlação de Spearman foram utilizados para fins estatísticos. Foi adotado o nível de significância de 5%. RESULTADOS: As sobreviventes de câncer de mama apresentaram significativamente maiores escores de fadiga total e das subescalas do que o grupo controle (todos os valores de p<0,05). Além disso, as sobreviventes relataram pior qualidade de vida nos domínios físico (p=0,002), psicológico (p=0,03) e relações sociais (p=0,03) do que o grupo controle. Nenhuma diferença foi encontrada para o domínio ambiental (p=0,08) entre os 2 grupos. Para as sobreviventes de câncer de mama...

Differences in Muscle Strength, Balance Function, Quality of Life, and Fatigue Levels between Cancer Survivors and Healthy Subjects: a cross-sectional study.

“…Numerous previous studies have demonstrated increased levels of fatigue in post-treatment cancer survivors when compared to control groups 36,37 . Thus, our findings are also in line with the previous reports on fatigue.…”

Prevalence of food‐allergen and aeroallergen sensitization among people in Sichuan, Western China: An 8‐year observational study

“…Milk protein allergy became a worldwide medical concern while most study paid attention to infants and young children but not old people. Old people in 71‐90 years old had higher morbidity of many diseases such as cancer and Alzheimer's disease, and their health conditions were usually not good . Allergic diseases could do harm to the old as badly as to children.…”
