Treatments for carcinoma of the subglottis

The following are treatment options for the stages of carcinoma of the subglottis. Your healthcare team will suggest treatments based on your needs and work with you to develop a treatment plan.

Stages 1 and 2 carcinoma of the subglottis

Radiation therapy and surgery are the treatments used for stages 1 and 2 carcinoma of the subglottis.

Radiation therapy is a common treatment for stages 1 and 2 carcinoma of the subglottis.

Surgery is done if the tumour doesn’t respond to radiation therapy.

Stage 3 carcinoma of the subglottis

Treatment for stage 3 carcinoma of the subglottis is often a combination of surgery, radiation and chemotherapy.

Radiation therapy may be used:

  • with chemotherapy given during the same time period (chemoradiation)
  • alone after surgery or for people who cannot cope well with chemoradiation and surgery

Chemotherapy may be used:

  • with radiation therapy given during the same time period (chemoradiation)
  • as the first treatment (induction chemotherapy) before treatment with chemoradiation

Surgery done for stage 3 carcinoma of the subglottis includes a laryngectomy with a partial thyroidectomy and modified radical neck dissection. It is usually followed by radiation therapy.

Stage 4 carcinoma of the subglottis

Treatment for stage 4 carcinoma of the subglottis is often a combination of surgery and radiation. 

Surgery done for stage 4 carcinoma of the subglottis includes a laryngectomy, total thyroidectomy and radical neck dissection. It is usually followed by radiation therapy.

Radiation therapy alone is used for people who can’t have or don’t want surgery.

Recurrent carcinoma of the subglottis

Recurrent carcinoma of the subglottis means that the cancer has come back after it has been treated. Treatments for recurrences include:

  • further surgery with or without radiation therapy after surgery
  • further radiation therapy for small recurrences for people who cannot have or don’t want to have a laryngectomy
  • chemotherapy
  • immunotherapy

If you can’t have or don’t want cancer treatment

You may want to consider a type of care to make you feel better without treating the cancer itself. This may be because the cancer treatments don’t work anymore, they’re not likely to improve your condition or they may cause side effects that are hard to cope with. There may also be other reasons why you can’t have or don’t want cancer treatment.

Talk to your healthcare team. They can help you choose care and treatment for advanced cancer.
