Overview
Complications
- Airway obstruction
- Difficulty swallowing
- Disfigurement of the neck or face
- Hardening of the skin of the neck
- Loss of voice and speaking ability
- Spread of the cancer to other body areas (metastasis)
Prognosis
Throat cancers can be cured in 90% of patients if detected early. If the cancer has spread to surrounding tissues or lymph nodes in the neck, 50 - 60% of patients can be cured. If the cancer has spread (metastasized) to parts of the body outside the head and neck, the cancer is not curable and treatment is aimed at prolonging and improving quality of life.
After treatment, patients generally need therapy to help with speech and swallowing. A small percentage of patients (5%) will not be able to swallow and will need to be fed through a feeding tube.
5-Year Survival
- Between 2004 and 2010, the 5-year relative survival of patients with laryngeal cancer was 62.6%.[1]
- When stratified by age, the 5-year relative survival of patients with laryngeal cancer was 61.5% and 58.2% for patients <65 and ≥ 65 years of age respectively.[1]
- The survival of patients with laryngeal cancer varies with the stage of the disease. Shown below is a table depicting the 5-year relative survival by the stage of laryngeal cancer:[1]
| Stage | 5-year relative survival (%), (2004-2010) |
| All stages | 60% |
| Localized | 75.1% |
| Regional | 43.4% |
| Distant | 35.1% |
| Unstaged | 55.7% |
- Shown below is an image depicting the 5-year conditional relative survival (probability of surviving in the next 5-years given the cohort has already survived 0, 1, 3 years) between 1998 and 2010 of laryngeal cancer by stage at diagnosis according to SEER. These graphs are adapted from SEER: The Surveillance, Epidemiology, and End Results Program of the National Cancer Institute.[1]
