Maeda T, Hiura A, Uehara J, et al. - Findings demonstrate usefulness of neutrophil-to-lymphocyte ratio (NLR) as a biomarker in cutaneous squamous cell carcinoma (cSCC) as it is not only simple to measure but can also predict prognosis.

• A single-center retrospective case series to determine the association between the NLR and the disease-specific survival (DSS) and sentinel lymph node (SLN) positivity in cSCC cases.

• Patients with cSCC who had blood tests before the initiation of treatment were analyzed.

• Increased NLR was an independent prognostic factor for poor DSS.

• An elevated NLR was identified as a predictive factor for SLN positivity.
