According to current ESMO – MASCC guidelines, a combination of a neurokinin-1 receptor antagonist (NK1RA), dexamethasone and a 5-HT3 receptor antagonist (5-HT3RA) is recommended to prevent carboplatin-induced emesis, albeit with moderate level of confidence and not unanimous consensus. We performed a meta-analysis of randomized trials (RCTs) comparing NK1RA + dexamethasone + 5-HT3RA vs. dexamethasone + 5-HT3RA in patients receiving the first cycle of carboplatin-based chemotherapy. Primary outcome was complete response (CR), defined as no emesis and no use of rescue medication. 9 trials were eligible, and data of CR were available from 8 trials (1598 patients). Addition of NK1RA improves CR in all phases: acute phase, 94.5% vs. 90.1%; delayed phase, 76.4% vs. 61.7%; overall period, 75.3% vs. 60.4%. There was no significant heterogeneity among trials. In patients receiving carboplatin-based chemotherapy, the addition of NK1RA to dexamethasone and 5-HT3RA is associated with a statistically significant and clinically relevant improvement in CR.
