Abstract
Neurokinin-1 receptor antagonists are playing a major advance in Chemotherapy-Induced Nausea and Vomiting (CINV) as powerful prophylactic agents. Therefore, it is significant to find the association between risk factors of patients and CINV so as to adjust the anti-emetic regimens. To evaluate the role of Neurokinin-1 Receptor (NK-1R) antagonist in preventing chemotherapy-induced vomiting in the acute and delayed phases following the first cycle of treatment. 145 adult patients with various cancers were recruited in Shanghai Changhai Hospital between September 2017 to November 2017, receiving dual or triple antiemetics. NK-1R antagonist combined with dexamethasone, 5-HT3R antagonist could effectively control delayed- vomiting in patients after Cycle 1 chemotherapy treatment (4.1% vs. 15.6%, P = 0.041<; 0.05). This study also showed that a history of motion sickness was a predictor of chemotherapy-induced vomiting (CINV) (P = 0.023 <; 0.05). In delayed phase a low consumption of alcohol and history of CIV for males were also significantly associated with CINV (P = 0.036 <; 0.05 and P = 0.002 <; 0.05 respectively). In this study, we found that triple anti-emetic regimen with NK-1R antagonist could effectively prevent the delayed-vomiting than dual agents. Moreover, some risk factors were observed to be associated with CINV in the delayed phase.
