Table 4

Barriers of nutrition support among cancer patients.

Barriers	Possible reason
Misunderstanding of nutrition support	Many cancer patients and their families ignored the importance of nutrition support and misunderstand its effects.
Economic factors	Cancer therapies are long-term and costly.; The nutrition products covered by social insurance are a priority to use in clinical practice, and the number of EN products covered by social insurance is less than that of PN products [57].
Lack of standard guidelines	The adherence to the guidelines published by nutritional institutions needs to be improved, and the medical staff want more detailed and practical guidance.
Over workload	Nutrition support always accompanies with long-term nutrition counselling for cancer patients during the whole therapy program, and it takes lot of human resource.
Loss of appetite	Many cancer patients will lose their appetites and need regular nutrition assessment and adjustment of nutrition support.
