Role of Percutaneous Endoscopic Gastrostomy for the Nutrition of Head and Neck Cancer Patients before and up to 6 Months after Cancer Treatment.

This retrospective monocentric cohort study analyzed patients with head and neck cancer according their nutritional status and association of percutaneous endoscopic gastrostomy (PEG) from admission to six months after treatment at a tertiary hospital in Germany from 2017 to 2019. A total of 289 patients (76.5% men; median age 62 years; 63.3% stage IV) were included. Univariate analyses and ANOVAs with repeated measures were performed to analyze differences over time. The percentage of patients requiring PEG was 14.9% (43 of 289 patients) before start of treatment (Z0), 14% (40 of 286 patients alive) after one week (Z1), 22.7% (58 of 255 patients) after six weeks (Z2) and 23% (53 of 230 patients) after six months (Z3) from the end of treatment. PEG placement was associated with alcohol or nicotine consumption, in oropharyngeal and hypopharyngeal carcinoma, squamous cell carcinoma, cancer stage III/IV, chemotherapy and impairment of food intake (all < 0.05). Weight loss between Z1 and Z3 with PEG did not differ from patients without PEG at Z0 ( = 0.074), although patients with PEG at Z0 had a lower mean weight at the beginning. PEG was important for a quarter of the patients alive at Z3 and helped to prevent weight loss.
