The triplet antiemetic regimen is administered to prevent chemotherapy-induced nausea and vomiting (CINV) after moderately emetogenic chemotherapy (MEC). However, the superiority of palonosetron over first-generation 5-hydroxytryptamine-3 receptor antagonists in triplet antiemetic therapy remains unclear. In this study, we evaluated the efficacy of palonosetron (PALO) and granisetron (GRA) in triplet antiemetic therapy for CINV. This study included 267 patients who received MEC at our hospital between April 2017 and September 2020. Patients were pretreated with antiemetic therapy comprising PALO or GRA and dexamethasone on day 1 and aprepitant on days 1–3. We evaluated the rate of complete response (CR) (i.e., no vomiting and no use of rescue medication) in the acute phase (0–24 h), delayed phase (24–120 h), and overall phase (0–120 h) after first-cycle chemotherapy. Furthermore, multivariate analysis was conducted to identify risk factors for non-CR. The rate of CR in the overall and delayed phases was significantly higher in the PALO group (91.9 and 91.9%, respectively) than in the GRA group (74.1 and 75.5%, respectively). In the acute phase, the incidence was not different between the GRA and PALO groups (96.5 and 99.2%, respectively). Multivariate analysis revealed that female sex and the use of GRA were risk factors for non-CR. Subgroup analysis revealed the superiority of PALO over GRA in female patients, but not in male patients. In conclusion, PALO was more effective than GRA in triplet antiemetic therapy in preventing CINV during MEC, especially for female patients.
