Evaluation of Combination Antiemetic Therapy on CINV in Patients With Gynecologic Cancer Receiving TC Chemotherapy

Background/Aim: The incidence of delayed chemotherapy-induced nausea and vomiting (CINV), especially nausea, in gynecologic cancer patients who receive paclitaxel and carboplatin (TC) chemotherapy is unclear. We assessed risk factors for delayed CINV in these patients, and examined whether it was controlled with combination antiemetic therapy. Materials and Methods: Data were pooled from two prospective studies, and compared between the two antiemetic prophylaxis groups using inverse probability of treatment weighted (IPTW) analysis. Results: Among the 182 evaluable patients (mean age: 56.2 years), three antiemetics gave better overall control than two for delayed nausea (42.9% vs. 57.4%,) and vomiting (13.8% vs. 34.5%). Risk factor for delayed nausea was age [odds ratio (OR)=0.953; p=0.0898[and use of two antiemetics (vs. three antiemetics) for delayed vomiting (OR=0.304; p=0.0732). Conclusion: A combination of three antiemetics controls delayed CINV among patients who undergo TC chemotherapy. Identification of risk factors can facilitate personalized treatments.
