A randomized open-label study of guideline-driven antiemetic therapy versus single agent antiemetic therapy in patients with advanced cancer and nausea not related to anticancer treatment

Abstract

Background: Nausea/vomiting (N/V) not related to anti-cancer treatment is common in patients with advanced cancer. The standard approach to management is to define a dominant cause, and treat with an antiemetic selected through pathophysiologic knowledge of emetic pathways. High rates of N/V control have been reported using both etiology-based guideline-driven antiemetic regimens and an empiric approach using single agents in uncontrolled studies. These different approaches had never been formally compared. Methods: This randomized, prospective, open label, dose-escalating study used readily available antiemetics in accordance with etiology-based guidelines or single agent therapy with halop..
