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.

ETHNOPHARMACOLOGICAL RELEVANCE: Sida tuberculata R. E. Fries (Malvaceae) is a pioneer species considered a weed in farm fields in Southern Brazil. Widely distributed in South Brazil, S. tuberculata is popularly used to treat inflammatory conditions. AIMS OF THE STUDY: The current study aimed to assess the in vitro cytotoxic and in vivo anti-inflammatory properties of S. tuberculata. MATERIALS AND METHODS: Initially, extracts obtained from leaves (STLE) and roots (STRE) were submitted to cytotoxicity tests using human leukocytes (non-malignant cell line) and HepG2 and MCF-7 (tumor cell lines). In sequence, anti-inflammatory properties were investigated against carrageenan-induced peritonitis model. RESULTS: In vitro analyses displayed a significant decrease in human leukocytes viability without genotoxic damage. IC50 results from tumor cells presented significant decrease in cell viability, slightly more pronounced for STRE. In addition, STLE significantly inhibited the inflammatory and oxidative parameters (TBARS, NPSH, SOD, MPO activity, cell influx, and cytokines release). CONCLUSION: Our findings indicate S. tuberculata extracts have cytotoxic potential more pronounced on tumor cell lines, as well as leaves extract shows a significant reduction in acute inflammation process, as already reported for Sida genus and specifically for this species.
