Chinese Medicine in Cancer Treatment - How is it Practised in the East and the West?

Abstract

Chinese medicine therapies in cancer treatment are very common in the East. Although it is usually classified as a form of complementary and alternative therapy in the West, Chinese medicine is an independent medical profession in Hong Kong and mainland China. It has a different perspective in understanding health and diseases compared with Western medicine. In oncology practice, whereas Western medicine focuses on direct tumour eradication by surgery, radiation therapy and systemic therapies, Chinese medicine focuses on restoring body balance and enhancing the body's defences (immunity), in addition to some cytotoxic herbal therapies. Most often patients, especially those in the East, receive both treatments. Chinese medicine is also commonly used to reduce side-effects from chemotherapy or radiation therapy, to aid recovery after an operation, to palliate symptoms and to address survivorship issues. However, this raises concerns of drug-herb interactions and toxicity in combination therapies. Commonly used Chinese medicine treatment modalities include acupuncture, moxibustion, diet therapy, prescribed Chinese medicine herbal decoction, single Chinese medicine herbs or supplements and tai chi. Although there is an increasing trend of Chinese medicine use in cancer patients in both the East and the West, the scientific evidence of safety and efficacy is often questioned by oncologists. This article reviews the current evidence in different Chinese medicine therapies in cancer management in both the East and the West.
