Presence and Duration of Feeding Tube in a 5-Year Cohort of Patients with Head and Neck Cancer Treated with Curative Intensity-Modulated Radiation Therapy.

Background Our study assessed post-radiation therapy (RT) G-tube presence, duration, and clinical predictors in patients with head and neck cancer (HNC). Methods We identified those 1-5-years post-RT with stage III/IV nasopharyngeal, oropharyngeal, hypopharyngeal, laryngeal, or unknown primaries. Logistic regression identified predictors of post-RT G-tube presence, Kaplan-Meier analysis estimated G-tube days, and log-rank test compared by tumor site. Results The 977 patients had mean age 60.6 +/- 11.6 years, 804 (82.3%) male, 764 (78.2%) stage IV, and 618 (63.3%) oropharyngeal primaries. All patients received intensity-modulated RT (IMRT), 571 (58.4%) received chemotherapy, and 698 (71.4%) prophylactic G-tube. G-tube prevalence 1- and 5-years post-IMRT was 7.1% and 4.8%, respectively. Median post-IMRT G-tube days were overall 63 (95%CI: 56-70), nasopharynx 119 (95%CI: 109-131), oropharynx 57 (95%CI: 51-68), hypopharynx 126 (95%CI: 77-256), larynx 53 (95%CI: 21-63), unknown 30 (95%CI: 17-55), of which hypopharynx was highest p < 0.001. Conclusions At an institution offering prophylactic G-tube for patients with advanced HNC, no differences were found in yearly G-tube use 1-5 years post-IMRT. Across all patients, median post-IMRT days with G-tube was 63 day but those with hypopharyngeal tumors registered the most days.
