The influence of supportive nutritional therapy via percutaneous endoscopically guided gastrostomy on the quality of life of cancer patients.

Between April 1987 and May 1990 a total of 212 consecutive patients with tumours in the head and neck region were admitted to a prospective study comparing planned prospective enteral nutrition via percutaneous endoscopically guided gastrostomy (PEG; n = 47) and oral nutrition (n = 134). The nutritional status (anthropometric and laboratory chemical parameters) and the quality-of-life index according to Padilla et al. [Res Nurs Health 6:117-126 (1983)] were determined prior to radiotherapy, 2, 4, 6 weeks later during radiotherapy and 6, 12 and 18 weeks after completion of radiotherapy. The quality-of-life score of the orally nourished patients decreased quickly during radiotherapy and improved only slowly afterwards. Although PEG patients had a worse starting score, their quality-of-life index did not deteriorate during therapy (statistically significant difference between the two groups). The same applies to the nutritional status. These results show that an early and constant enteral nutrition by PEG can stabilize the nutritional state and the quality of life of patients with tumours of the head and neck area during radiotherapy.
