概述
Laryngeal cancer is a malignancy that arises in the larynx (voice box), located in the throat. The most common type is squamous cell carcinoma, affecting the cells lining the larynx. It is strongly associated with smoking and heavy alcohol use.
The larynx is divided into three parts:
- Supraglottis (above the vocal cords)
- Glottis (the vocal cords)
- Subglottis (below the vocal cords)
症状
- Hoarseness or voice changes lasting >2 weeks
- Sore throat
- Persistent cough
- Difficulty or pain when swallowing
- Ear pain
- Lump in the neck
- Breathing difficulties (advanced cases)
病因与风险因素
- Smoking (major risk factor)
- Alcohol consumption
- HPV infection (especially in supraglottic cancers)
- Male gender and age >50
- Occupational exposure (asbestos, wood dust, chemicals)
诊断方法
- Laryngoscopy (direct visualization)
- Biopsy
- Imaging: CT, MRI, or PET scan
- HPV testing (in selected cases)
治疗方案
- Radiation therapy (early-stage)
- Surgery (partial or total laryngectomy)
- Chemoradiation (advanced stages)
- Voice rehabilitation (if vocal cords are removed)
预后情况
- Varies by tumor location and stage
- 5-year survival:
- Early-stage glottic: >80%
- Advanced-stage: 30–60%
- HPV-positive tumors may respond better to treatment
