Introdução: O cancro é uma das doenças com mais mortalidade no mundo, no entanto, devido
aos avanços na medicina, cada vez há mais sobreviventes. Tanto no decorrer do tratamento
como após o tratamento, cada vez mais pacientes se queixam de problemas cognitivos,
nomeadamente na memória e na atenção. O défice cognitivo relacionado ao cancro (Cancer
Related Cognitive Impairment - CRCI) é o nome dado ao fenómeno do impacto do cancro na
cognição. Para além dos sintomas do CRCI, é cada vez mais notório que outros fatores como
os psicológicos (depressão, stress e ansiedade) impactam tanto o declínio cognitivo como a
qualidade de vida destes pacientes. Com isto, torna-se necessário analisar os resultados
referentes a estes estudos. Objetivo: Rever sistematicamente a literatura existente de forma a
explorar a associação entre fatores psicológicos e défice cognitivo em pacientes que sejam
submetidos a tratamentos oncológicos sistémicos. Método: Foi realizada uma pesquisa
sistemática nas seguintes bases de dados: PubMed/MEDLINE, EBSCO, Web of Science e
Scopus. Resultados: Foram identificados 19716 artigos e após processo de triagem foram
incluídos 47 artigos na revisão sistemática. Conclusão: Uma grande percentagem dos estudos
revela que os fatores psicológicos como depressão, ansiedade e stress têm correlação com as
funções cognitivas de pacientes com cancro.
ABSTRACT: Introduction: Cancer is one of the deadliest diseases in the world, but due to advances in medicine there are more survivors. However, both during and after treatment, a significant number of patients complain of cognitive problems, particularly in memory and attention. Cancer-related cognitive impairment (CRCI) is the name given to the recurring phenomenon associated with the cognitive effects of cancer. In addition to the symptoms of CRCI, it is becoming increasingly clear that other factors such as psychological factors (depression, stress and anxiety) play a role in both cognitive decline and the quality of life of these patients. Therefore, it is necessary to analyze the results of these studies. Objective: To systematically review the existing literature to explore the association between psychological factors and cognitive impairment in patients undergoing systemic treatment for cancer. Method: A systematic search was carried out in the following databases: PubMed/MEDLINE, EBSCO, Web of Science and Scopus. Results: 19716 articles were identified and after a screening process 47 articles were included in the systematic review. Conclusion: A large percentage of the studies reveal that psychological factors such as depression, anxiety and stress are correlated with the cognitive functions of patients with cancer.
