==Supportive Treatment==
Many patients also need swallowing rehabilitation after treatment to help them adjust to the changes in the structure of the throat.
 
==Radiation therapy==
There are two types of radiation therapy
*External beam radiation therapy
*Internal radiation therapy
*Radiation therapy may be helpful in patients who have stopped smoking before beginning treatment
*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

Overview

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. Multiple factors should be taken into account when considering treatment such as laryngeal preservation, maintaining the airway, swallowing and speech. Induction therapy includes 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 and concurrent consists of cisplatin (100 mg/m2 on days 1, 22, and 43) with radiation therapy.

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 should be taken into account when considering treatment: [2][3]

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 can be very helpful in preserving the larynx and voice. It has shown similar efficacy with concomitant cisplatin as the laryngectomy-free survival [6][7][8]
