Overview
The optimal therapy for laryngeal cancer depends on the stage at the time of diagnosis.
Medical Therapy
The medical therapy combined with radiation has largely replaced the surgical cure for laryngeal cancer. However, the treatment truly depends on the stage at the time of diagnosis.[1] Multiple factors will be taken into account when considering treatment: [2][3]
- Laryngeal preservation
- Maintaining the airway
- Swallowing
- Speech
Chemotherapy:
Chemotherapy consists of two phases[4][5]
Induction: Three cycles of continuous infusion of cisplatin (100 mg/m2 on day 1) plus fluorouracil (1000 mg/m2/day ) followed by definitive radiation therapy in the induction phase
Concurrent: Cisplatin (100 mg/m2 on days 1, 22, and 43) with radiation therapy
Radiation therapy
Radiotherapy may be of two types: External beam radiation therapy and internal radiation therapy[6]
- External radiation therapy to the thyroid or the pituitary gland may alter thyroid gland functioning
- Hyperfractionated radiation therapy and new types of radiation therapy are being studied in the treatment of laryngeal cancer
