Use of high-dose cisplatin with aprepitant in an outpatient setting

Chemotherapy-induced nausea and vomiting (CINV) and nephrotoxicity are adverse events induced by cisplatin administration. These effects can be reduced by treatment regimens with low-dose cisplatin, but high-dose cisplatin is still used. In Japan, high-dose cisplatin is usually administered in an inpatient setting to permit management of CINV. However, with use of new-generation antiemetic agents such as aprepitant, CINV and nephrotoxicity are controllable in an outpatient setting. Here, we discuss issues related to the management of high-dose cisplatin administration in outpatients. Grade 2 or worse CINV induced by high-dose cisplatin occurs in more than 40% of patients without treatment with aprepitant, but is controllable by administration of a 5-HT3 receptor antagonist, steroids and aprepitant. Moreover, prevention of CINV using these drugs is cost-effective, since outpatient settings have advantages with regard to health economics and patient quality of life. These findings suggest that shifting high-dose cisplatin administration to the outpatient setting may be achieved with co-administration of aprepitant. Available facilities and the status of the patient should be considered when selecting whether an outpatient setting is suitable for administration of cisplatin, but the use of aprepitant and adequate oral hydration should allow use of cisplatin in this setting.
