Prophylactic insertion of percutaneous endoscopic gastrostomy (PEG) tubes does not improve quality of life in patients with head and neck cancer (HNC), a recent study has shown.
Researchers enrolled 181 HNC patients (median age, 64 years; 73.5 percent male) who had had PEG tubes inserted before receiving cancer treatment. The European Organization for Research and Treatment of Cancer Quality of life questionnaire (EORTC-QLQ) was used to quantify the study outcome.
Participants were categorized into three groups according to the use of the feeding tubes: total nutrition (group A; n=149), supplemental nutrition to complement oral food intake (group B; n=17) or no use of the feeding tube (group C; n=15).
At a median of 21.6 months after PEG insertion, 50.3 percent (n=91) of the patients agreed to be interviewed over the phone. Median overall QLQ scores at follow-up for groups A, B and C were 50.0, 41.6 and 58.3, respectively. Statistical significance was not achieved (p=0.378).
However, analysis by individual scales revealed important differences. Bodily function, for example, appeared to be better in patients who used PEG tubes less (median scores: group A, 66.6; group B, 80.0; group C, 93.3; p=0.034). No such differences were found for social, cognitive and emotional function.
Similarly, symptom burden of fatigue (p=0.869), pain (p=0.375) and nausea/emesis (p=0.667) were all unaffected by the use of PEG tubes.
There were significant differences in the subjective evaluations of PEG tubes. Those in groups A and B, for example, generally perceived PEG tubes to be beneficial and were more open to undergoing a repeat procedure in the future.
