Significance of Anthropometric and Nutritive Factors in Oral and Oropharyngeal Cancer Patients Undergoing Free Flap Reconstruction

Purpose: This study analyzed associations between preoperative nutritional status and the incidence of early postoperative complications as a primary outcome in patients with oral and oropharyngeal cancer undergoing free flap reconstruction. We hypothesized that preoperative nutritional status may be linked with specific complications, allowing for better preoperative risk assessment. Patients and methods: This longitudinal, retrospective cohort study encompassed 113 patients, all treated surgically for oral and oropharyngeal cancer in the period from March 2013 up to March 2018 in a tertiary referral center. Variables considered were preoperative and postoperative serum albumin and protein values ; body mass index ; waist-to-hip ratio ; circumference of the neck, waist, hip, and thigh ; number of cigarettes smoked per day during the 10- year period before surgery ; average alcohol consumption ; operative time ; and postoperative albumin administration. Results: Our study identified preoperative protein serum concentration (≤62 g/L), postoperative albumin administration (≥200 mL), number of cigarettes smoked per day (>20), and prolonged operative time (≥450 minutes) to be associated with postoperative complications. Conclusions: This is the first study reporting cutoff values of clinical significance in assessing patient preoperative nutritional status in light of reducing postoperative complications after free flap reconstruction.
