Background:
Laryngocarcinoma (LC) is a common malignant tumor of the head and neck, accounting for 1% to 5% of human tumors. The primary objective of the present study was to evaluate the survival time of patients with LC at different sites.
Methods:
Information concerning patients with LC was extracted from the Surveillance, Epidemiology, and End Results (SEER) database between 1975 and 2016.
Results:
In total, 16 255 patients with LC were selected from the SEER database. Among all patients, 80.2% were male; males also predominated in each tumor site subgroup. Most of the patients were aged between 60 and 69 years, had white ethnicity, were single, and had American Joint Committee on Cancer (AJCC) stage I cancer with T1, N0, and M0. The present study investigated the role of interventions in all LCs at different AJCC stages. Across the whole population, regardless of the intervention used, survival increased in patients at any cancer site.
Conclusions:
The study found that male sex, age ≥80 years, black ethnicity, single status, T4, N4, M1, and AJCC stage IV were associated with higher mortality rates at all sites of LC. Aggressive interventions, especially surgery and radiotherapy, may improve survival in patients with LC at different sites and with different AJCC stages.
