Controlling chemotherapy-induced nausea requires further improvement: symptom experience and risk factors among Korean patients.

Nausea control, especially in the delayed phase, has room for improvement.

Future studies should evaluate the contribution of risk factors when antiemetic prophylaxis is fully provided in multiple settings.
