The Management of Opioid-Induced Nausea and Vomiting in Patients with Cancer: A Systematic Review
A partir d'une revue systématique de la littérature sur la période 1966-2017 (15 études, 1 524 patients), cette étude analyse la prise en charge des nausées et vomissements induits par les opioïdes chez les patients atteints de cancer
Background: Opioids are the foundation of treatment for cancer pain but can cause side-effects, one of the most common being nausea and vomiting, which can impair quality of life. Objective: To evaluate the evidence for the management of opioid-induced nausea and vomiting. This systematic review was undertaken as part of an update of the European Association for Palliative Care's opioid guidelines. Design: Searches of MEDLINE (1966–2017) and EMBASE (1980–2017) were done. Key eligibility criteria were: randomized controlled trials conducted in patients with cancer. The Grading of Recommendations Assessment Development and Evaluations system was applied to formulate recommendations. Results: Fifteen studies were eligible (1524 patients). The studies were grouped as follows: opioid switching (n = 8); the use of antiemetics to treat opioid-induced nausea and vomiting (n = 4); and change of route of administration of the opioid (n = 3). Three recommendations were formulated: A weak recommendation for switching from morphine to oxycodone in cancer patients with nausea (quality D); a weak recommendation for switching from tramadol to either codeine or hydrocodone for pain in cancer patients with nausea (quality D); and a weak recommendation for switching from morphine/oxycodone to methadone using the three-day switch method in patients with increasing pain considered untreatable with further opioid titration and/or with opioid-related side effects (quality C). Conclusions: This systematic review can make only weak recommendations for the management of opioid-induced nausea and vomiting. There remains a need for high-quality studies before strong recommendations on the management of opioid-induced nausea and vomiting can be made.
