Impact of Diagnostic and Treatment Delays on Survival and Treatment-Related Toxicities in Portuguese Patients With Head and Neck Cancer.

Publication date: Jan 01, 2024

Delays in diagnosis and initiation of treatment have a negative impact on the prognosis and survival of head and neck cancer (HNC) patients. These delays also involve more intensive treatments with greater toxicity, dysfunction, and morbidity. This was a retrospective observational study with patients diagnosed with HNC between January 1, 2018, and December 31, 2021. The main objective was to estimate whether the time to diagnosis (TD) and time until treatment initiation (TIT) translated into changes in the patient’s overall survival (OS). Multivariate data analysis was performed with the Cox regression model. Significance was considered for p
