Esophageal Cancer

Esophageal cancer is a malignant neoplasm arising from the mucosal lining of the esophagus. It primarily manifests as two histological types: Squamous Cell Carcinoma (SCC) and Adenocarcinoma. It is characterized by aggressive behavior and high mortality rates, often presenting late in the disease course due to the esophagus's elastic wall structure, which allows significant tumor growth before luminal obstruction occurs.

Etiology varies by histology. SCC is strongly associated with tobacco use and alcohol consumption, particularly in developing regions. Adenocarcinoma is primarily driven by chronic gastroesophageal reflux disease (GERD) and Barrett’s esophagus, where chronic acid exposure induces columnar metaplasia, eventually progressing to dysplasia and carcinoma. Genetic predisposition, such as Tylosis, plays a minor role.

The transition from normal epithelium to malignancy involves chronic inflammation leading to genomic instability. In adenocarcinoma, the "reflux-metaplasia-dysplasia-adenocarcinoma" sequence is central. In SCC, chronic mucosal irritation by carcinogens leads to cumulative genetic mutations in genes like TP

1. The esophagus lacks a serosa, allowing tumors to invade adjacent structures like the trachea, aorta, and mediastinum early.

Esophageal cancer is the eighth most common cancer worldwide. It shows a strong male predominance. SCC is more common in East Asia and parts of Africa, while adenocarcinoma is the predominant form in North America and Western Europe due to the rising prevalence of obesity and GERD.

• Tobacco and alcohol use
• Chronic GERD
• Barrett's esophagus
• Obesity
• Achalasia
• Human Papillomavirus (HPV)
• Hot beverage consumption
• Dietary deficiencies (vitamin A, zinc)

A. Early Symptoms

• Mild, intermittent dysphagia


• Substernal discomfort


• Heartburn B. Common Symptoms


• Progressive dysphagia (solids to liquids)


• Unexplained weight loss


• Odynophagia (painful swallowing) C. Advanced Symptoms


• Hoarseness (laryngeal nerve involvement)


• Persistent cough


• Hematemesis


• Bone pain (metastasis) D. Emergency Symptoms


• Aspiration pneumonia


• Tracheoesophageal fistula


• Severe GI hemorrhage

Usually unremarkable in early stages. Advanced findings include cervical lymphadenopathy (Virchow’s node), hepatomegaly (metastasis), cachexia, and signs of pleural effusion or anemia (pallor).

A. Clinical Assessment: History of dysphagia and weight loss.
B. Laboratory Testing: CBC (anemia), liver function tests.
C. Imaging Studies: CT chest/abdomen/pelvis, PET/CT.
D. Functional Tests: Esophageal manometry if motility is suspected.
E. Biopsy Findings: Definitive tissue diagnosis via EGD.
F. Genetic Testing: HER2/neu status for treatment planning.
G. Differential Diagnosis: Peptic stricture, esophageal web, achalasia, eosinophilic esophagitis.

Complete Blood Count (CBC)
Type: Blood Test
Purpose: Assess for iron-deficiency anemia
Expected Findings: Low hemoglobin/hematocrit
Interpretation: Likely occult blood loss or malnutrition

• Endoscopic Ultrasound (EUS): High accuracy for T-staging and N-staging.
• PET/CT: Essential for identifying distant metastases and metabolic activity.
• Barium Swallow: Detects structural narrowing or "apple-core" appearance.

Esophageal strictures (benign), Schatzki ring, Achalasia, Plummer-Vinson syndrome.

Malnutrition, aspiration pneumonia, fistula formation, local invasion, systemic metastases.

A. Lifestyle Modifications: Smoking cessation, alcohol abstinence, weight management.
B. Preventive Measures: Treating GERD, routine screening for Barrett’s esophagus.
C. Medical Treatment: - Chemotherapy: Cisplatin, 5-Fluorouracil, Paclitaxel.

• Targeted Therapy: Trastuzumab (if HER2+).

Overall 5-year survival is approximately 20%. Prognosis depends heavily on stage at diagnosis; localized disease has significantly higher survival than metastatic disease.

Primary: Abstinence from tobacco/alcohol, healthy diet.
Secondary: Surveillance endoscopies for Barrett’s esophagus.
