Diagnosis of laryngeal cancer

Laryngeal cancer accounts for about 1% to 2% of all tumors in the body. It is more common in people aged 50 to 70, and more common in men. The cause is still difficult to determine. About 90% of laryngeal cancers are squamous cell carcinomas, 2% are adenocarcinomas, and undifferentiated carcinomas and sarcomas are rare.

1. Supraglottic type: The incidence rate is about 30%. In the early stage, there is a foreign body sensation in the throat and discomfort in the pharynx. If the vocal cords are invaded, there will be hoarseness and difficulty breathing. In the late stage, there will be bloody sputum. This tumor develops quickly and is easy to metastasize to the deep upper cervical lymph nodes.

2. Glottic type: about 60%, progressive hoarseness, glottis obstruction, laryngeal wheezing and dyspnea, bloody sputum in late stage. Not easy to metastasize to cervical lymph nodes

3. Subglottic type: accounts for about 6%. There may be no symptoms in the early stage, but cough, bloody sputum, obstruction of the subglottic area and difficulty breathing may occur later.

4. Under laryngoscope, the tumor is cauliflower-like, ulcerative, nodular or mass-like, etc. The vocal cords can move in the early stage, but they are restricted or fixed later.

5. Patients with hoarseness for more than 4 weeks, age over 40, or throat discomfort, foreign body sensation, or throat pain all need to undergo laryngoscopy.

6. Biopsy is the main basis for the diagnosis of laryngeal cancer. If a highly suspected patient has a negative biopsy result, multiple biopsies are required.

7. Direct laryngoscopy, microlaryngoscopy, and fiberoptic laryngoscopy.

8. Dynamic laryngoscope is used to examine early vocal cord lesions. For example, if one side of the vocal cord vibrates abnormally or vibration disappears during speech, it often indicates the possibility of early vocal cord cancer.
