Abstract: Malnutrition is frequently present among cancer patients, which diminishes treatment efficacy while increasing therapeutic side effects. Therefore, it is essential to set standards for National Good Nutrition Therapy Ward (GNT Ward) to regulate the nutritional care practice in a clinical setting. Cancer nutrition therapy (CNT), developed based on oncology and nutrition theory, aims to treat cancer and its complications, enhance physical conditions, and improve the prognosis via nutritional interventions. CNT consists of 3 stages, including nutritional diagnosis, nutritional intervention, and efficacy evaluation. A GNT Ward title is granted to a ward, a department, and/or a hospital, who performs the standardized CNT. These units showcase CNT in practice and provide guidance to their counterparts. Grade III comprehensive hospitals, capable Grade II comprehensive hospitals, and all cancer specialized hospitals are encouraged to establish a GNT Ward. The establishment of the GMT Ward is of great significance on a national scale regarding preventing and/or treating cancer-related malnutrition, improving cancer therapy efficacy, securing the health care safety for patients, ameliorating the quality of life, extending the survival time, and saving medical costs.
