The objective of this study was to evaluate whether aprepitant in addition to 5-HT3 receptor antagonist is useful for preventing chemotherapy-induced nausea and vomiting (CINV) and anorexia in patients receiving CHOP therapy, and to evaluate the relationship between in vivo kinetics of plasma substance P and these adverse events. Patients with malignant lymphoma who received CHOP chemotherapy or THP (THP-ADR)-COP therapy were investigated CINV and anorexia for 5 days after start of chemotherapy. With the first course of chemotherapy, all patients received only granisetron on day1 as an antiemetic. Patients who experienced nausea, vomiting or anorexia exceeding grade 1 in the first course received aprepitant for 3 days in addition to granisetron with the second course of CHOP chemotherapy. Plasma substance P concentrations at 24 and 72h after chemotherapy were measured. Nineteen patients were evaluated. Nausea, vomiting or anorexia was observed with the first course in 7 of 19 patients. During the second course with aprepitant, no patients experienced vomiting, and the toxicity grade of nausea, vomiting or anorexia was decreased compared with those in the first course. Substance P concentrations showed no differences after chemotherapy, in patients with nausea, vomiting or anorexia and in patients without. Addition of aprepitant to 5-HT3 receptor antagonist appears effective for CINV or anorexia for patients who received CHOP chemotherapy.
