Using coword analysis and chord diagrams to examine the effect of nutritional counseling and support (DCNS) on patients with oral and oropharyngeal cancer.

Future studies should preferably use randomized trials to compare standard DCNS with more intensive DCNS, which includes earlier and/or prolonged treatment.
