Side effects of prophylactic percutaneous endoscopic gastrostomy placement

March 15, 2011

A research team from United States determined the rate of use and non-use of prophylactic percutaneous endoscopic gastrostomy (PEG) tubes among patients with head and neck cancer patients. They found that there is a high rate of unnecessary PEG placement when done prophylactically in patients with head and neck cancer.

Impairment of oral intake occurs in the majority of patients with (HNC) receiving chemoradiotherapy. Placement of prophylactic percutaneous endoscopic gastrostomy (PEG) tube in asymptomatic newly diagnosed HNC before chemoradiation is a common practice in some centers. In some studies, PEG has been associated with a decrease in treatment related weight loss in patients with HNC, but no studies have examined the utilization rate.

A research article published on February 28, 2011 in the addresses this question. The authors have observed anecdotally that a number of HNC patients who received a prophylactic PEG tube in fact never used them. They performed a retrospective database study of all patients in whom PEG tube was placed for HNC to determine the prevalence of unused prophylactically placed PEG tubes. Data were also analyzed for possible factors predictive of unused PEGs or PEGs used for less than 2 wk.

This is the first study that addressed the issue of use of prophylactic PEG in HNC patients. The result of this study showed that a significant number of patients (47%) with prophylactic PEG tubes never used their PEG or used it for less than 2 wk. No association with PEG use vs non-use was observed for cancer diagnosis, stage, or specific .

The study suggests prophylactic PEG placement prior to HNC therapy is associated with a high rate of non use or limited use. Further prospective studies evaluating specific selection criteria for prophylactic PEG in this setting are needed. Similarly, additional studies are needed to assess the impact of prophylactic PEG tube placement on the cost-effectiveness of cancer care, quality of life, hospital admission rate, and, most importantly, survival.
