By literature search, we found that the related research in China was very limited. The impact of TAs to patients was often ignored during the cancer clinical care. The objective of this article is to investigate the symptoms, mechanisms, impact and treatment of cancer-related TAs. Methods Literature search for cancer-related TAs was performed in PubMed up to July 2015, resulting 88 articles. We picked up the key information from each article and integrate them together into every conclusion. Results Symptoms of cancer-related TAs including changes in taste acuity& taste quality, food aversion and xerostomia.
