The aim of this study is to analyse the relationship between albumin levels and prognosis in patients with head and neck squamous cell carcinoma (HNSCC). Methods: We performed a retrospective study in a cohort of 741 patients with HNSCC and a plasmatic albumin testing within the 4 weeks prior to the start of treatment. The relationship between disease-specific survival and plasma albumin levels was analysed by a recursive partitioning analysis. Results: Albumin levels showed a directly proportional and statistically significant association with disease-specific survival. According to the results of the recursive partitioning analysis, the cut-off points with a higher prognostic capacity were 37.5 g/L and 46.1 g/L. Taking patients with albumin levels > 46.1 g/L as the benchmark, patients with albumin levels between 37.5-46.1 g/L had a 1.44 times higher risk of disease-specific death (95% CI: .95-2.19, P = .081), and patients with levels < 37.5 g/L had a 3.19 times higher risk (95% CI: 2.01-5.04, P = .0001). The differences in survival based on albumin levels were only seen in patients with advanced stage tumours (stages III-IV). Conclusion: Pre-treatment plasmatic albumin is an independent prognostic factor for patients with advanced stage HNSCC (III-IV), 37.5 g/L being the cut-off point with the highest prognostic capacity.
