Impact of nutritional status at the outset of assessment on postoperative complications in head and neck cancer.

Half of the patients presenting with head and neck tumor are malnourished at the outset of treatment. Muscle mass loss (sarcopenia) seems to be critical. The aim of the present study was to assess the impact of nutritional status and sarcopenia on postoperative complications in head and neck cancer. A retrospective study for the period November 2014 to May 2016 included 92 patients operated on for head and neck squamous cell carcinoma. Complications at 30 days were graded on the 5-level Clavien-Dindo classification. Nutritional status was assessed anthropometrically (weight), biologically (albuminemia and Nutrition Risk Index (NRI)), on CT (muscle mass index at 3rd lumbar vertebra) and functionally (Short Physical Performance Battery). Assessment was made at the outset of management, and nutritional treatment was initiated as appropriate. Potential risk factors for postoperative complications were assessed: performance status, prior radiation therapy, smoking and alcohol abuse. 54% of patients were malnourished on the NRI. 41% had grade ≥ 2 complications. The most frequent complications were infection and healing disorder. The risk of complications was higher in case of malnutrition (62% vs. 17%; P < 0.001) and sarcopenia (56% vs. 22%; P < 0.01), with 50% longer hospital stay (P = 0.04). Malnutrition and sarcopenia are independent risk factors for postoperative complications. [ABSTRACT FROM AUTHOR]
