RESUMEN
AIMS AND OBJECTIVES: To describe the main acupuncture techniques and parameters that have been used in the most varied symptoms of different types of cancer. BACKGROUND: Clinical evidence about the potential effectiveness of acupuncture and related therapies to control signs and symptoms associated with cancer or its treatment has been in several studies. Currently, there is already evidence of the use of acupuncture for the treatment of nausea and vomiting, fatigue, dry mouth, anxiety, depression, insomnia and pain. However, many studies lack firm rights or reproducible guidelines for treatment. DESIGN: This study performs a systematic review of clinical trials related to the topic, based on the PRISMA protocol. Thus, a search was carried out in the Scopus, Pubmed and Web of Science databases, covering studies since January 2007. METHODS: Structured and organised according to PICO standards, using keywords ("cancer" OR "malignant tumour" OR "chemotherapy" OR "radiotherapy") AND ("acupuncture" OR "electroacupuncture") AND ("pain" OR "nausea" OR "vomit" OR "fatigue" OR "xerostomia" OR "insomnia" OR "depression" OR "neuropathy"). RESULTS: After the selection and evaluation phase, 23 studies were included and analysed. CONCLUSION: Based on this analysis, it is concluded that acupuncture is safe and there is evidence of the reduction of gastrointestinal symptoms, chemotherapy-induced peripheral neuropathy, pain, dry mouth, fatigue, insomnia, and improvement of cognitive capacity. RELEVANCE TO CLINICAL PRACTICE: Acupuncture treatments could act by minimising the side effects of conventional treatments and reducing symptoms induced by tumours. NO PATIENT OR PUBLIC CONTRIBUTION: The patients had no direct involvement with the study in question.
