[Theory of unpleasant symptoms: support for the management of symptoms in children and adolescents with cancer]. / Teoria dos sintomas desagradáveis: subsídios para o manejo de sintomas em crianças e adolescentes oncológicos.

ABSTRACT

OBJECTIVE: To present an overview of the clusters of neuropsychological symptoms in children and adolescents with cancer from the perspective of the Theory of Unpleasant Symptoms. METHODS: A theoretical and reflective study based on international literature and the critical analysis of the authors. RESULTS: In scientific literature, there is scarcity of international studies and an absence of studies in Brazil regarding the neuropsychological symptom clusters in children and adolescents with cancer. The theory of unpleasant symptoms is consistent because it emphasizes the complexity and interaction of the symptoms, the interrelationship between symptoms, the factors that influence symptoms, and the results and consequences of symptoms, thus supporting the planning of nursing interventions in paediatric oncology. CONCLUSION: It is essential to update knowledge on this subject and discuss the theories that support research and the clinical practice of symptom management in order to better qualify nursing care.
