ASCO, NCCN, MASCC/ESMO: a comparison of antiemetic guidelines for the treatment of chemotherapy-induced nausea and vomiting in adult patients

Chemotherapy-induced nausea and vomiting (CINV) is a common toxicity that may impair the quality of life of patients with a variety of early- and end-stage malignancies. In light of recent changes in the optimal management of CINV, we undertook this narrative review to compare the latest guidelines published by ASCO (2017), NCCN (2018), and MASCC/ESMO (2016). The processes undertaken by each organization to evaluate existing literature were also described. Although ASCO, NCCN, and MASCC/ESMO guidelines for the treatment and prevention of CINV share many fundamental similarities, literature surrounding low and minimal emetic risk regimens is lacking. Data regarding the use of complementary alternative medicine for CINV is particularly scarce and in need of further investigation.
