ABSTRACT
Objective To evaluate the efficacy and safety of neurokinin1 (NK1) receptor antagonist aprepitant combined with prednisone and tropisetron in prevention of nausea and vomiting (CINV) induced by R-CHOP or CHOP regimen. Methods A total of 90 patients with diffuse large B-cell lymphoma (DLBCL) who accepted R-CHOP or CHOP regimen in the People''s Hospital of Tianjin from October 2015 to January 2016 were divided into aprepitant group (45 cases) and the control group (45 cases) according to the random number table. In aprepitant group, day 1: aprepitant 125 mg 1 h before chemotherapy, prednison 100 mg, tropisetron 10 mg, and tropisetron 5 mg 2 hours after chemotherapy;day 2-3:aprepitant 80 mg and prednison 100 mg, tropisetron 10 mg; day 4-5: prednison 100 mg. In the control group, day 1: prednison 100 mg 1 h before chemotherapy, tropisetron 10 mg, and tropisetron 5 mg 2 h after chemotherapy; days 2-3: prednison 100 mg, tropisetron 10 mg; day 4-5: prednison 100 mg. Data on nausea, vomiting and remission treatment were collected every day. The complete remission (CR) rates of CINV without vomiting and remission drugs in the whole cycle were recorded. Functional living index-emesis questionnaire (FILE) was used to assess the effect of CINV on the life quality of the patients. Results CR in aprepitant group was higher than that in the control group (77.8 ％ vs. 55.6 ％, χ2= 5.000, P= 0.025). The rate of no vomiting in aprepitant regimen was higher than that in the control regimen (82.2 ％ vs. 62.2 ％, χ2 = 4.486, P= 0.034). The average scores of FILE between the two groups were (113 ±10) and (100 ±11) scores respectively, and there was a significant difference (t=12.437, P<0.001). The related adverse reactions of vomiting-stopping drugs in both groups had no statistical difference. Conclusion The aprepitant combined with tropisetron and prednisone can improve effectively nausea and vomiting induced by R-CHOP or CHOP chemotherapy regimen for DLBCL patients.
