OBJECTIVE
Chemotherapy-induced nausea and vomiting (CINV) is one of the most frequently encountered side effects of cancer treatment. Severe CINV can lead patients to refuse chemotherapy, which ultimately affects cancer outcomes. The development of fairly new antiemetic agents, 5-hydroxytryptamine-3 receptor antagonists, palonosetron and neurokinin-1 receptor antagonists and aprepitant has reduced the risk and incidence of CINV. In this study, we assessed the efficacy of aprepitant plus palonosetron against palonosetron for CINV in patients receiving moderately emetic cancer chemotherapy (paclitaxel and carboplatin combination [TC] therapy).
METHODS
Between November 2010 and March 2014, 78 patients with gynecological cancer treated with TC therapy were randomized into two groups: an aprepitant group (administered aprepitant, dexamethasone and palonosetron) and a control group (administered dexamethasone and palonosetron). The primary study endpoint was complete response, defined as the complete absence of emetic events in the delayed phase.
RESULTS
The complete response rate in the delayed phase differed significantly between the two groups, with 82% in the aprepitant group and 97% in the control group (P = 0.025).
CONCLUSIONS
The combination of aprepitant and palonosetron appears to be of greater efficacy than palonosetron alone for the prevention of delayed-phase CINV induced by TC therapy.
