ContextPain is the most fearful symptom in cancer. Although there is a relationship between psychosocial variables and oncologic pain, psychological and non-pharmacological treatments for pain management in cancer patients are not very widespread.ObjectivesTo analyze the efficacy of psychological and non-pharmacological treatments for reducing pain in cancer patients.MethodsWe performed a systematic review following the PRISMA protocol. In January 2021, data were extracted from PubMed, Web of Science and Scopus, including randomised controlled trials (RCT) published in the last five years (from 28 January, 2015 to December 15, 2020), in the English language and whose sample was patients with cancer pain. The database search used the following keywords: cancer, cancer-related pain, psychological intervention, non-pharmacologic intervention. The Cochrane risk of bias assess ment for randomised trials (RoB 2) was used for quality appraisal.ResultsAfter the inclusion and exclusion criteria were applied, ten papers were fully screened. The evidence suggested that the most effective interventions to reduce cancer pain were mindfulness-based cognitive therapy, guided imagery and progressive muscle relaxation and emotional and symptom focused engagement (EASE). Music therapy and brief cognitive behavioral strategies (CBS) require more research, while coping skills training and yoga did not show positive effects. Overall, we obtained a moderate size effect (d = 0.642, 95% CI: 0.125-1.158) favourable to psychological and non-pharmacologic treatments at post-treatment, which increased at follow-up (k = 5, d = 0.826, 95% CI: 0.141-1.511).ConclusionThis study provides insight into psychological interventions which might be applied and contribute to cancer-related pain reduction in adults. Although the results are not completely consistent, they may shed light on psychology applications in the oncology environment.Copyright © 2021 American Academy of Hospice and Palliative Medicine.
