Objective: The significance of this article is to talk about aprepitant and olanzapine 5 mg, compare them, and deeply explore the safety or effectiveness during the whole process of multiple-day cisplatin chemotherapy-induced vomiting and nausea., Methods: This trial was randomized and prospective. It is needed to receive cisplatin chemotherapy (25 mg/m2/d) for three days. Its patients would need to choose to use 5 mg olanzapine or aprepitant for this treatment, combined with 5-HT3 receptor antagonist plus dexamethasone. The primary endpoints were the total protection (TP) during the acute phase (AP) (0-24 hours), delayed phase (DP) (25-120 hours), and overall phase (OP) (0-120 h) between the two groups. The secondary endpoints were the complete response (CR) and total control (TC) during the three phases. The first time of the whole process is particularly important and needs to be observed vigorously. However, the time of the patient's first vomiting symptom is also compared accurately by using the Kaplan-Meier curve. The functional life index vomiting (FLIE) was used to calculate and carefully evaluate the serious impact of nausea and vomiting (CINV) induced by the whole chemotherapy process on the quality of life. About olanzapine, its related symptoms and other side effects and aprepitant were also recorded., Results: (1) The primary endpoint TP rates of the olanzapine and aprepitant groups were similar; for the AP, they were 94.23% (98/104) vs. 95.45% (98/106) P =0.61( P =0.61); for the DP, they were 54.81% (57/104) vs. 54.72% (58/106) ( P =0.99), and for the OP, the values were 53.79% (58/105) and 55.31% (56/104), respectively ( P =0.99). The secondary endpoints, the TC rates, and CR rates were also comparable in the three phases ( P > 0.05). (2) After research and display, the results showed that there was no significant difference between the two groups when they were used for the first time of vomiting and the FLIE index ( P > 0.05). (3) The main olanzapine-related adverse event was drowsiness, while that of aprepitant was constipation., Conclusion: The efficacy of 5 mg olanzapine was similar to that of aprepitant, and it also showed an advantageous economic potency ratio in preventing CINV induced by multiple-day cisplatin chemotherapy with increased sedation side effects., Competing Interests: The authors declare that they have no conflicts of interest., (Copyright © 2022 Guang Liu et al.)

Objective: To assess the safety and efficacy of combined neurokinin-1 antagonist aprepitant treatment for multiple-day anthracycline chemotherapy-induced nausea and vomiting., Methods: 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/m 2 /d for pirarubicin or 45 mg/m 2 /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)., Results: 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)., Conclusion: 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., (Copyright © 2019 The Authors.

To perform a prospective non-randomized comparison of the effectiveness and safety of combined neurokinin-1 antagonist aprepitant treatment with the standard multiple-day cisplatin regimen for the prevention of cisplatin-induced nausea and vomiting (CINV).
