About Chemotherapy-Induced Nausea and Vomiting (CINV)CINV is estimated to afflict 85% of cancer patients undergoing chemotherapy and can result in a delay or even discontinuation of chemotherapy treatment. The advent of 5­-HT3 receptor antagonists has revolutionized the management of nausea and vomiting experienced by cancer patients undergoing chemotherapy. Due to increased number of cancers in the world, the supportive care area is becoming of paramount importance to help patients dealing with adverse events of anticancer therapies. When patients support better the anticancer treatment they increase their chances to a better quality of life and to a successful treatment.
