What is Laryngeal Cancer — Diagnosis, Voice Preservation, and Modern Treatment?

Laryngeal cancer is overwhelmingly squamous cell carcinoma (>95%) arising from the mucosal surfaces of the larynx, anatomically divided into glottic (true vocal cords), supraglottic (epiglottis, false cords, ventricles), and subglottic regions. Each subsite demonstrates distinct epidemiology, lymphatic drainage, presenting symptoms, and prognosis. Glottic cancers (60%) typically present early due to hoarseness from vocal cord involvement and have favorable prognosis given limited lymphatic supply. Supraglottic cancers (35%) often present later with regional metastases due to rich bilateral lymphatic drainage. Subglottic cancers (5%) are rare and typically aggressive with paratracheal nodal involvement.

The dominant etiology involves synergistic effects of tobacco (cigarettes, cigars, pipes) and alcohol consumption, accounting for over 75% of cases, with multiplicative rather than additive risk. Other risk factors include occupational exposures (asbestos, wood dust, paint fumes), gastroesophageal reflux disease, prior head and neck radiation, and human papillomavirus (rising significance though less established than for oropharyngeal cancer). Field cancerization concept explains synchronous and metachronous second primaries throughout the upper aerodigestive tract.

Modern staging utilizes AJCC 8th edition TNM system incorporating depth of invasion, vocal cord mobility, cartilage invasion, and extralaryngeal extension. Treatment paradigms have evolved from primary surgery toward organ preservation through concurrent chemoradiation for many advanced cases, while early stage disease may be effectively treated with single modality (radiation or transoral laser/robotic surgery) preserving voice. Total laryngectomy remains essential for advanced disease, salvage after chemoradiation failure, and dysfunctional larynx. Voice rehabilitation post-laryngectomy includes tracheoesophageal puncture with voice prosthesis, electrolarynx, and esophageal speech.

Symptoms

Persistent hoarseness lasting more than 2-3 weeks (glottic cancer)
Throat pain or otalgia (referred ear pain)
Foreign body sensation, dysphagia, or odynophagia
Hemoptysis or blood-tinged sputum
Cervical lymphadenopathy (more common in supraglottic)
Stridor or respiratory distress (advanced disease)
Unexplained weight loss in advanced cases

Risk Factors

Tobacco use, particularly cigarette smoking
Heavy alcohol consumption
Synergistic tobacco-alcohol exposure (multiplicative risk)
Occupational exposures (asbestos, wood dust, paint, formaldehyde)
Gastroesophageal reflux disease
Prior radiation exposure to head and neck
Male sex (4:1 male predominance)

When to See a Doctor?

If you experience any of the following symptoms, seek medical attention promptly:

  • Hoarseness persisting more than 2-3 weeks (urgent ENT referral)
  • New cervical lymphadenopathy without obvious cause
  • Unexplained throat or ear pain
  • Dysphagia, odynophagia, or globus sensation
  • Hemoptysis or blood-tinged sputum
  • Stridor or respiratory difficulty
  • Unexplained weight loss with throat symptoms

Treatment Methods

01
Early stage glottic cancer: transoral laser microsurgery or radiation therapy
02
Transoral robotic surgery for selected supraglottic cancers
03
Concurrent chemoradiation (cisplatin) for organ preservation in advanced disease
04
Cetuximab combined with radiation for cisplatin-ineligible patients
05
Total laryngectomy for advanced disease or salvage after chemoradiation failure
06
Voice rehabilitation post-laryngectomy: tracheoesophageal puncture with voice prosthesis
07
Multidisciplinary care with otolaryngology, radiation oncology, medical oncology, speech-language pathology

Anaemia

Dahiliye (İç Hastalıkları)

Anaemia is a low haemoglobin level that reduces oxygen delivery, causing fatigue, pallor, and shortness of breath. It is not a disease itself but a sign of many underlying conditions. Most cases are correctable with appropriate diagnosis and treatment.

Iron Deficiency Anaemia

Dahiliye (İç Hastalıkları)

Iron deficiency anaemia develops when dietary intake, absorption, or losses create an iron shortfall, most often affecting women and children. Identifying the underlying cause is the core of management, alongside iron replacement.

Vitamin B12 Deficiency

Dahiliye (İç Hastalıkları)

Vitamin B12 deficiency can cause megaloblastic anaemia, neurological symptoms, and cognitive impairment. Early treatment with intramuscular or oral B12 largely prevents irreversible complications.

Hypertension (High Blood Pressure) Management

Dahiliye (İç Hastalıkları)

Hypertension is often called the silent killer because it progresses symptom-free for years and can damage the heart, brain, kidneys, and eyes. Regular monitoring, lifestyle change, and evidence-based drug therapy dramatically reduce cardiovascular risk.

Chronic Kidney Disease

Dahiliye (İç Hastalıkları)

Chronic kidney disease is one of the most common complications of chronic conditions such as diabetes and hypertension, and can be silent in its early stages.

Hepatitis B (HBV)

Dahiliye (İç Hastalıkları)

Hepatitis B is a DNA virus infection causing acute and chronic hepatitis with risk of cirrhosis and hepatocellular carcinoma; diagnosis integrates HBsAg, HBeAg, anti-HBc, and HBV DNA with management based on disease phase using nucleos(t)ide analogues (entecavir, tenofovir) and universal infant vaccination.

Hepatitis C (HCV)

Dahiliye (İç Hastalıkları)

Hepatitis C is an RNA virus causing chronic hepatitis that may progress to cirrhosis and hepatocellular carcinoma; modern direct-acting antiviral (DAA) pangenotypic regimens (sofosbuvir/velpatasvir, glecaprevir/pibrentasvir) achieve sustained virologic response over 95% in 8–12 weeks with universal adult screening and cure for nearly all patients.

Fatty Liver Disease

Dahiliye (İç Hastalıkları)

Non-alcoholic fatty liver disease (NAFLD) is closely related to obesity and metabolic syndrome and is largely reversible with early treatment.
