Poor oral intake causes enteral nutrition dependency after concomitant chemoradiotherapy for pharyngeal cancers

To identify precipitating factors responsible for enteral nutrition (EN) dependency after concomitant chemoradiotherapy (CCRT) of head and neck cancers and to examine their statistical correlations.
Factors related to feeding condition, nutritional status, disease, and treatment of 26 oropharyngeal and hypopharyngeal cancer patients who received definitive CCRT were retrospectively investigated by examining their medical records. The days of no oral intake (NOI) during hospitalization and the months using enteral nutrition after CCRT were counted as representing the feeding condition, and the changes in body weight (BW) were examined as reflecting nutritional status. The factors related to EN dependency after CCRT were analyzed.
Long duration of total NOI (≥ 30 days) and maximum NOI ≥ 14 days were significant predictors of EN dependency. Decreased BW (≥ 7.5 kg) was the next predictor identified, but it was not significant. Multivariate analysis showed that the total duration of NOI was more correlated with EN dependency than changes in BW.
A long duration of NOI was more strongly related to EN dependency than nutritional factors.
