Thyroid dysfunction after combined therapy for laryngeal cancer: a prospective study.

Area of Science:

• Endocrinology
• Oncology
• Otorhinolaryngology

Background:

• Larynx cancer treatment often involves laryngectomy and radiotherapy.
• Thyroid dysfunction is a potential complication following these treatments.
• Identifying risk factors for hypothyroidism is essential for patient management.

Purpose of the Study:

• To determine the incidence of thyroid dysfunction in patients treated for larynx cancer.
• To identify risk factors associated with the development of hypothyroidism post-treatment.

Main Methods:

• Prospective study in a tertiary care center.
• Thyroid function tests performed on 75 patients preoperatively, before radiotherapy, and postoperatively.
• Multivariate analysis used to assess risk factors.

Main Results:

• Hypothyroidism incidence was 49.3% with a mean detection time of 6 months post-treatment.
• Risk factors identified include radiotherapy dose, laryngectomy type, neck dissection extent, thyroid lobectomy, and thyroiditis.
• All 75 patients were male, with a mean age of 59.4 and average follow-up of 28.6 months.

Conclusions:

• Periodic thyroid function monitoring is vital for patients treated for larynx cancer.
• Early diagnosis and treatment of hypothyroidism can be achieved by monitoring patients with risk factors.
• This proactive approach improves patient outcomes and management of thyroid dysfunction.
