Pre-treatment anemia in head and neck cancer: risk factors, subtypes, and survival outcomes.

Introduction: Anemia in head and neck cancer (HNC) may be due to additive, overlapping or competing causes. Here we aim to investigate the prevalence of pre-therapeutic anemia, associated risk factors, subtypes, and impact on survival among HNC patients, including the clinically relevant subgroups of HPV-associated HNC.

Materials And Methods: A retrospective chart review of HNC patients diagnosed between 2010 and 2020 identified a study cohort of 921 patients.
