[Efficacy of Antiemetic Therapy with Aprepitant, Palonosetron, and Dexamethasone in Patients Receiving Oxaliplatin-Based Chemotherapy].

Antiemetic therapy with aprepitant, palonosetron, and dexamethasone is recommended for moderately emetogenic chemotherapy in several guidelines to prevent chemotherapy-induced nausea and vomiting. There is a lack of information about the efficacy and safety of antiemetic therapy with aprepitant, palonosetron, and dexamethasone in patients treated with oxaliplatin in Japan. We recruited patients with untreated colorectal cancer who underwent oxaliplatin-based chemotherapy. All patients were treated with aprepitant, palonosetron, and dexamethasone. The complete response and complete protection rates were analyzed. A total of 52 patients were enrolled in this clinical trial. The complete response rate overall, and in the acute and delayed phases was 92.3%, 98.1%, and 92.3%, respectively. The complete protection rate overall and in the acute and delayed phases was 73.1%, 86.5%, and 73.1%, respectively. Grade 3-4 non-hematological toxicity did not occur. Antiemetic therapy with aprepitant, palonosetron, and dexamethasone is effective and safe in patients treated with oxaliplatin.
