Nutritional status and body composition of patients with head and neck cancer treated with perioperative evidence-based nutritional management.

We aimed to describe nutritional status and body composition profiles perioperative head and neck cancer (HNC) patients managed with whole-course nutritional support. Scored Nutritional Risk Screening (NRS 2002), Patient-Generated Subjective Global Assessment (PG-SGA), and body composition were conducted. The factors related to weight loss and skeletal muscle mass (SMM) were identified. Lower weight and body composition levels in low skeletal muscle index (SMI≤9.90 kg/m ² ) group were observed. Levels of albumin, prealbumin, prognostic nutritional index (PNI), and lymphocyte-to-monocyte ratio (LMR) were lower than pre-operative, but the values after 2 weeks were higher than 1 week post-operatively (all p <0.01). The neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) were increased at 1 and 2 weeks post-operative compared to pre-operative (both p <0.01). Post-operatively, NLR at 2 weeks was lowed than 1 week ( p  = 0.02). A negative correlation was observed between SMM loss and serum prealbumin ( r  = -0.255, p  = 0.029). Pre-operative BMI ( p <0.01), tumor differentiation ( p  = 0.003), and nutritional risk ( p  = 0.049) were risk factors for weight loss. In conclusions, for perioperative HNC patients, loss of adipose tissue occurred earlier than muscle. Prealbumin should be considered as an indicator for monitoring of recovery in clinical practice.
