Is there a place for nutrition in palliative care?

Although nutritional interventions are becoming widely used in cancer patients, purposes and results of such treatment are not always well-defined. This is because nutrition is traditionally considered a palliative treatment to be confined to the area of palliative cares, whereas the modern approach includes nutrition as an early supplemental support to improve compliance of patients with the oncologic therapies and total parenteral nutrition may be recommended in patients who would be destined to succumb prior from starvation-malnutrition than from tumour progression. Purpose of this paper if to define the potential as well as the limitations of nutritional interventions on both the survival and the quality of life of the advanced cancer patients.

Some RCT on the use of oral, enteral and supplemental parenteral nutrition in patients on oncologic therapy show some benefit on compliance with therapy and in some domains of quality of life. Some malnourished (hypo)aphagic incurable cancer patients may survive longer thanks to parenteral nutrition, while few data suggest that quality of life may be maintained for a limited period of time. With a few exceptions, oncology and nutrition have till recently travelled on parallel tracks without talking each other. The oncologist who knows the natural history of the patients should understand which risk of complication and of poor tolerance to the treatment can malnourished patients carry and which is the potential of parenteral nutrition in hypophagic incurable patients.
