Prophylactic placement of gastrostomy feeding tubes before radiotherapy in patients with head and neck cancer: is it worthwhile?

BACKGROUND: After radiation treatment of head and neck cancer, placement of gastrostomy feeding tubes can be technically difficult. The practice of placing tubes before treatment is probably justified if the tube is used for more than 4 weeks and if complications are infrequent. The aim of this study was to determine the outcome of prophylactically placed gastrostomy tubes in patients with head and neck cancer at our institution from 1995 to 1999. STUDY: Data collected retrospectively from the patients' medical records included demographics, duration of tube use, and complications associated with placement.
RESULTS: A total of 54 patients (40 men, 14 women) with a mean age of 68.5 years (range, 49-88 years) were studied. Thirty-one patients were treated with both surgery and radiotherapy; 17, with only radiotherapy; and 6, with chemotherapy, radiation, and surgery. The gastrostomy tube was placed before initiation of radiation treatment in 41 patients and after treatment in 13. The method of placement included pull technique (n = 41), introducer technique (n = 10), and surgical (n = 3). Four patients who had a tube placed after treatment required hospitalization for dehydration, whereas no hospitalizations were needed in the prophylactic group. The median duration of tube use was 165 days (range, 0-1,105 days). Only three patients had a complication directly related to placement.
CONCLUSION: Gastrostomy tube placement before treatment is appropriate, given the median number of days required for use and limited complications associated with placement.
