The use of adjunctive traditional Chinese medicine therapy and survival outcome in patients with head and neck cancer: a nationwide population-based cohort study

Abstract

Our study showed that adjunctive therapy with TCM is associated with higher survival outcome. However, some limitations exist, such as the lack of information of cancer stage. In addition, causality cannot be assessed with this retrospective study. A randomized controlled trial to test the effect of adjunctive TCM therapy in HNC patients is needed.
