Abstract(s)
A doença oncológica é uma realidade com um crescimento progressivo na
população mundial sendo que, em Portugal, o cancro da mama é o mais prevalente. O
presente estudo surge no sentido de contribuir para a melhor compreensão do impacto
do cancro da mama no funcionamento cognitivo, percebido e objetivo, e na qualidade de
vida e a relação com a prática do exercício físico nesta população. A amostra de
sobreviventes de cancro da mama da Beira Interior foi recolhida por conveniência e
inclui um grupo com intervenção, com prática de exercício sistemático específico para
esta população e um grupo de controlo equivalente. Foi constituída por 41 mulheres
sobreviventes de cancro da mama, com idades entre os 39 e os 68 anos (M = 53.95; DP
= 7.82). Foi realizada entrevista semiestruturada guiada por questionário
sociodemográfico e clínico, e aplicados os seguintes instrumentos: Auditory Verbal
Learning Test (AVLT), Código – Tarefa de codificação, Testes de fluência verbal (TFV),
Memória de dígitos, Stroop, European Organisation for Research and Treatment of
Cancer Quality of Life Questionnaire C30 (EORTC QLQ-C30) e The Functional
Assessment of Cancer Therapy-Cognitive Function-Version 3 (FACT-Cog-v3). Os
resultados revelam que a amostra não apresenta deterioração do funcionamento
cognitivo, percebido e objetivo, nem da qualidade de vida, ao invés, a memória imediata
apresenta uma média amostral que se encontra acima do intervalo normativo da
população portuguesa, não reunindo condições para testar se esta diferença é
estatisticamente significativa. São visíveis correlações positivas entre o funcionamento
cognitivo percebido (PCA) e objetivo (avaliado pelo TFV e pelo Código) com os anos de
escolaridade e entre a qualidade de vida e o funcionamento cognitivo objetivo (avaliado
pelo AVLT e pela Memória de Dígitos). Também são observáveis várias correlações entre
o funcionamento cognitivo percebido e a qualidade de vida.
No que concerne à comparação entre o grupo de controlo e o grupo com
intervenção apenas se verificaram diferenças significativas relativamente ao
funcionamento cognitivo objetivo (avaliado pelo AVLT), revelando uma valorização da
memória no grupo com intervenção, e ao funcionamento cognitivo percebido baseado
nos comentários de outras pessoas (FACT-Cog-Oth), que se apresenta mais elevado no
grupo de controlo. A discussão dos resultados e as implicações clínicas e de investigação
são apresentadas neste trabalho.
Oncological disease is a reality that is growing progressively in the world population, and in Portugal breast cancer is the most prevalent. This study aims to contribute to a better understanding of the impact of breast cancer on cognitive functioning, both perceived and objective, and on quality of life and the relationship with physical exercise in this population. The sample of breast cancer survivors from Beira Interior was collected by convenience and included an intervention group, with systematic exercise specifically for this population, and an equivalent control group. It consisted of 41 female breast cancer survivors aged between 39 and 68 (M = 53.95; SD = 7.82). A semi-structured interview was conducted, guided by a sociodemographic and clinical questionnaire, and the following instruments were applied: Auditory Verbal Learning Test (AVLT), Code - Coding Task, Verbal Fluency Test (VFT), Digit Memory, Stroop, European Organization for Research and Treatment of Cancer Quality of Life Questionnaire C30 (EORTC QLQ-C30) and The Functional Assessment of Cancer Therapy-Cognitive Function-Version 3 (FACT-Cog-v3). The results show that the sample has no deterioration in cognitive functioning, perceived or objective, or in quality of life. On the other hand, immediate memory has a sample average that is above the normative range for the Portuguese population, but there are no conditions to test whether this difference is statistically significant. Positive correlations are seen between perceived cognitive functioning (PCA) and objective cognitive functioning (assessed by the TFV and the Code) with years of schooling and between quality of life and objective cognitive functioning (assessed by the AVLT and Digit memory). Several correlations were also observed between perceived cognitive functioning and quality of life. With regard to the comparison between the control group and the intervention group, there were only significant differences with regard to objective cognitive functioning (assessed by the AVLT), revealing an increase in memory in the intervention group, and perceived cognitive functioning based on other people's comments (FACTCog- Oth), which was higher in the control group. The discussion of the results and the clinical and research implications are presented in this paper.
