Eur Arch Otorhinolaryngol. 2022 Nov 10. doi: 10.1007/s00405-022-07730-y. Online ahead of print.


BACKGROUND: Several reports examined the survival of laryngeal cancer (LC) patients, most of these studies only focused on the prognosis of the disease, and just a small number of studies examined non-cancer-related causes of death. The objective of the current study is to investigate and quantify the most common causes of deaths following LC diagnosis.

METHODS: The data of 44,028 patient with LC in the United States diagnosed between 2000 and 2018 were retrieved from the Surveillance, Epidemiology, and End Results (SEER) program and analyzed. We stratified LC patients according to various demographic and clinical parameters and calculated standardized mortality ratios (SMRs) for all causes of death.

RESULTS: Over the follow-up period, 25,407 (57.7%) deaths were reported. The highest fatalities (11,121; 43.8%) occurred within 1-5 years following LC diagnosis. Non-cancer causes of death is the leading cause of death (8945; 35.2%), followed by deaths due to laryngeal cancer (8,705; 34.3%), then other cancers deaths (7757; 30.5%). The most common non-cancer causes of death were heart diseases (N = 2953; SMR 4.42), followed by other non-cancer causes of death (N = 1512; SMR 3.93), chronic obstructive pulmonary diseases (N = 1420; SMR 4.90), then cerebrovascular diseases (N = 547; SMR 4.28). Compared to the general population, LC patients had a statistically significant higher risk of death from all reported causes.

CONCLUSIONS: Non-cancer causes of death is the leading cause of death in LC patients, exceeding deaths attributed to LC itself. These findings provide important insight into how LC survivors should be counselled regarding future health risks.
