Background Female gender, young age, first chemotherapy cycle, and low alcohol intake have all been linked to an increased risk of nausea and vomiting from chemotherapy. We intended to see if netupitant and palonosetron (NEPA) could prevent chemotherapy-induced nausea and vomiting (CINV) in patients with risk factors such as age, gender, chemotherapy cycle number, and alcohol consumption history. Methods In this retrospective study, chemotherapy-naïve patients who were prescribed netupitant (300 mg) and palonosetron (0.50 mg) (NEPA) before the first cycle of chemotherapy were analyzed for overall, acute, and delayed phases of complete response (CR), complete protection (CP), and control. Results In the acute phase (AP), delayed phase (DP), and overall phase (OP), complete response was 88.23%, 86.27%, and 86.27%, respectively; complete protection was 80.39%, 78.43%, and 76.47%, respectively; and complete control was 76.47%, 72.54%, and 70.58%, respectively, in the whole population (i.e., 51 patients). Complete response, protection, and control in the overall phase were achieved by 86.27%, 72.72%, and 68.18% of patients who received the highly emetogenic chemotherapy (HEC) regimen (i.e., 44 patients), respectively. Conclusion NEPA provided a consistent magnitude of benefit for patients who are at high risk, receiving HEC and moderately emetogenic chemotherapy (MEC), and having good control in the acute, delayed, and overall phases of CINV.
