Abstract
To assess the safety and efficacy of combined neurokinin-1 antagonist aprepitant treatment for multiple-day anthracycline chemotherapy-induced nausea and vomiting. One hundred patients with breast cancer from department of Medical Oncology of Ordos Central Hospital from June 2015 to February 2018 were selected and randomize subdivided into 2 groups. All cases received anthracycline (30 mg/m2/d for pirarubicin or 45 mg/m2/d for epirubicin) and cyclophosphamide adjuvant chemotherapy, along with either the standard therapy (dexamethasone and tropisetron) or the combined aprepitant therapy (aprepitant plus dexamethasone and tropisetron). The results of the observation between groups were presented by complete response in the overall phase (OP, 0-120 hours), acute phase (AP, 0-24 hours) and delay phase (DP, 25-120 hours). The Kaplan-Meier curves were plotted to exhibit the first time of vomiting, Functional Living Index-Emesis of patients' quality of life, and therapy-related adverse effects (AEs). The complete response of OP, AP, and DP were statistically different between aprepitant group and standard group (80.0% vs 48%, P = 0.001; 92.0% vs 74%, P = 0.017; 80.0% vs 48%, P = 0.001). The aprepitant group held a longer time reaching the first emesis after the relevant treatment than the standard group. The Functional Living Index-Emesis increased significantly in the aprepitant group compared with the standard group (24% vs 8.3%, P = 0.029). Fatigue and constipation were the only AEs of aprepitant, since no significant differences were observed in fatigue between the 2 groups (72% vs 70%, P = 0.826), while the incidence of constipation of aprepitant group was higher than the standard group (48% vs 28%, P = 0.039). Combined aprepitant therapy is efficient and safe in the multiple-day anthracycline chemotherapy-induced nausea and vomiting control and is recommended for the clinical use.
