Background: It is assumed that neoplasm greater in size may affect a patients’ nutritional status and prognosis stronger than smaller one. The aim of this study was to compare the nutritional status and prognosis of patients with laryngeal cancer (LC), recognized as tumour smaller in size, and patients with colorectal cancer (CRC) who were hospitalized in our hospital during the one year period. Methods: The retrospective review of medical documentation of all 1,134 patients hospitalized in a Department of Otolaryngology. Results: The laryngeal tumour was smaller than colorectal. Nutritional risk concerned 9% of patients with LC, was greater than in patients with other laryngeal disorders (1.4%), and lower than in patients with CRC (37%). A Nutritional Risk Screening (NRS) 2002 score ≥ 3 was the only significant factor influencing the risk of in-hospital all-cause mortality, 14- and 30-day readmissions in patients with LC, and the risk of 14-day rehospitalization in patients with CRC. Conclusions: Risk of malnutrition in patients with LC was lower than in counterparts with CRC, and concern 9% and 37% of patients, respectively. Nutritional risk diagnosed in patients with LC had a stronger association with the prevalence of the measured outcomes (in-hospital death, the risk of 14-day and 30-day readmission, length of hospitalization) than in individuals with CRC.
