Nausées et vomissements chimio-induits : physiopathologie, prophylaxie et recommandations

Abstract

Nausea and emesis are one of the most feared secondary effect of chemotherapy. The development of antiemetic therapies has increased after the introduction of cisplatin, a cytotoxin with the highest emetic potential. Chemotherapy-induced nausea and vomiting (CINV) have been classified into acute, delayed and anticipatory based on the time of onset. According to the percentage of nausea and emesis without any antiemetic treatment, chemotherapy is divised into highly, moderate, low and very low emetic potential. The discovery of emetics stimuli neurotransmitters and their receptors has led to the introduction of new molecules which associated with steroids have prevented nausea and vomiting chemotherapy-induced for 70 to 80% of the patients receiving chemotherapy with high emetic potential. Numerous studies have evaluated the various antiemetics and recommendations were issued by learned societies in US and Europe. This text discusses the physiopathology of nausea and vomiting, the development of anti-emetics and the new discovered antiemetics. Finally, a synthesis of the recommandations from the guidelines developed by the Multinational Association of Supportive Care in Cancer (MASCC), the American Society of Clinical Oncology (ASCO), the National Comprehensive Cancer Network (NCCN) and the European Society for Medical Oncology (ESMO) is presented.
