Evaluation of Contemporary Olanzapine- and Netupitant/palonosetron-Containing Antiemetic Regimens for Chemotherapy-Induced Nausea and Vomiting
HONG KONG MEDICAL JOURNAL(2023)
摘要
INTRODUCTION:This post-hoc analysis retrospectively assessed data from two recent studies of antiemetic regimens for chemotherapy-induced nausea and vomiting (CINV). The primary objective was to compare olanzapine-based versus netupitant/palonosetron (NEPA)-based regimens in terms of controlling CINV during cycle 1 of doxorubicin/cyclophosphamide (AC) chemotherapy; secondary objectives were to assess quality of life (QOL) and emesis outcomes over four cycles of AC.METHODS:This study included 120 Chinese patients with early-stage breast cancer who were receiving AC; 60 patients received the olanzapine-based antiemetic regimen, whereas 60 patients received the NEPA-based antiemetic regimen. The olanzapine-based regimen comprised aprepitant, ondansetron, dexamethasone, and olanzapine; the NEPA-based regimen comprised NEPA and dexamethasone. Patient outcomes were compared in terms of emesis control and QOL.RESULTS:During cycle 1 of AC, the olanzapine group exhibited a higher rate of 'no use of rescue therapy' in the acute phase (olanzapine vs NEPA: 96.7% vs 85.0%, P=0.0225). No parameters differed between groups in the delayed phase. The olanzapine group had significantly higher rates of 'no use of rescue therapy' (91.7% vs 76.7%, P=0.0244) and 'no significant nausea' (91.7% vs 78.3%, P=0.0408) in the overall phase. There were no differences in QOL between groups. Multiple cycle assessment revealed that the NEPA group had higher rates of total control in the acute phase (cycles 2 and 4) and the overall phase (cycles 3 and 4).CONCLUSION:These results do not conclusively support the superiority of either regimen for patients with breast cancer who are receiving AC.
