Nutrition in head and neck cancer care: a roadmap and call for research.

Survivors of head and neck cancer have complex nutritional and supportive care needs. These needs result from the tumour's proximity to organs essential for normal eating function and the intensive treatment targeting those organs. Despite the crucial role of nutrition and supportive care in head and neck cancer, research and funding are lacking compared with other cancer types.

Developing subscale threshold scores for the nutrition literacy assessment instrument (NLit).
