Psychological interventions have shown benefit in reducing symptoms in children and adolescents with cancer. More recently, mindfulness-based interventions (MBIs) have been shown to be a promising approach to symptom intervention in adolescents with chronic illnesses. In this systematic review, we aimed to describe MBIs or focused-breathing interventions that have been used to treat symptoms in children receiving cancer therapy. A systematic review was conducted using MEDLINE/PubMed, EMBASE, CINAHL, and PsycINFO from inception to September 2019. We identified relevant articles in which MBIs or focused-breathing interventions were the primary interventions delivered to improve symptoms in children or adolescents with cancer. Six studies met the inclusion criteria. MBIs included controlled breathing and belly breathing. Intervention effects were found to be beneficial with regard to symptoms that included procedural pain, distress, and quality of life. The interventions were generally well accepted and beneficial. All studies suffered limitations because of methodological flaws, including the lack of randomization, and small sample sizes. Despite the small numbers of studies and participants, MBIs delivered to children with cancer may have beneficial effects on certain symptoms. Implications for future research include interventions tailored to the specific symptom burden. Studies must aim to increase sample sizes as well as to include individuals at high risk for severe symptoms.
