Esophageal carcinoma develops when abnormal cells grow uncontrollably in the esophagus, the muscular tube that carries food from the mouth to the stomach. Esophageal cancer is often diagnosed at an advanced stage because early disease may cause mild or nonspecific symptoms.

There are two main types of esophageal cancer:

• Squamous cell carcinoma: Arises from the cells lining the upper and middle parts of the esophagus
• Adenocarcinoma: Develops in the lower esophagus, often in the setting of chronic acid reflux and Barrett’s esophagus

At OncoClinic, we support you with appropriate diagnostics, clear explanations, and a personalized care plan tailored to your diagnosis, overall health, and goals.

Signs and symptoms

• Difficulty swallowing (dysphagia), initially with solid foods and later with liquids
• Sensation of food getting stuck in the chest
• Chest pain or discomfort
• Heartburn or acid reflux that worsens
• Unintended weight loss
• Fatigue
• Hoarseness or chronic cough
• Other symptoms may include pain when swallowing, vomiting blood or black stools, and shortness of breath

Persistent swallowing difficulties or unexplained weight loss should be promptly evaluated by a healthcare professional.

Risk factors

• Age: Older age, most cases occur after age 60
• Gender: Men are affected more frequently than women
• Diet: A Diet low in fruits and vegetables
• Tobacco use: Tobacco use, particularly for squamous cell carcinoma
• Alcohol consumption: Heavy alcohol consumption, especially in combination with tobacco
• Gastrointestinal conditions Gastroesophageal reflux disease (GERD)
• Precancerous conditions: Barrett’s esophagus, a precancerous condition
• Obesity: Obesity, mainly associated with adenocarcinoma
• Radiation exposure: Previous radiation to the chest

Screening

There is no routine population-based screening for esophageal cancer, and screening is not recommended for the general population.

Screening recommendations

• Targeted surveillance may be considered for individuals with Barrett’s esophagus, usually with periodic upper endoscopy
• Patients with chronic reflux symptoms or known Barrett’s esophagus should discuss surveillance strategies with their healthcare provider

Diagnosis

Esophageal cancer is usually diagnosed after symptoms prompt further evaluation.

Diagnostic evaluation typically includes:

• Upper endoscopy, allowing direct visualization and biopsy of suspicious areas
• Biopsy, to confirm the diagnosis and determine tumor type
• CT scan of the chest and abdomen to assess disease extent

Additional tests may be used for staging and treatment planning.

Staging

Once esophageal cancer is confirmed, staging determines how far the disease has spread. Staging evaluation may include:

• CT scans of the chest and abdomen
• PET/CT scan to detect lymph node or distant spread
• Endoscopic ultrasound (EUS) to assess tumor depth and nearby lymph nodes

Esophaegeal cancer staging

Esophageal cancer is staged from Stage I to Stage IV:

• Stage I: Cancer confined to the inner layers of the esophagus
• Stage II: Tumor has grown deeper into the esophageal wall or involves nearby lymph nodes
• Stage III: Cancer has spread more extensively to surrounding tissues or multiple lymph nodes
• Stage IV: Cancer has spread to distant organs such as the liver or lungs

Treatment and procedures

At OncoClinic, esophageal cancer care is delivered through a multidisciplinary, patient-centered approach. Treatment is individualized based on cancer type, stage, and overall health.

Surgery: Surgery may be used for selected patients with localized disease. When surgery is indicated, procedures are performed at our accredited partner hospitals under the direct coordination and supervision of our medical team, ensuring continuity and quality of care.

Chemotherapy: Chemotherapy is commonly used before surgery, after surgery, or as part of treatment for advanced disease.

Radiation therapy: Radiation therapy is often combined with chemotherapy, particularly for locally advanced tumors.

Targeted therapy and immunotherapy: Used in selected patients based on tumor characteristics and molecular testing.

Combined treatment strategies: Many patients benefit from a combination of surgery, chemotherapy, and radiation therapy.

Palliative and supportive care: Supportive care focuses on symptom relief, nutritional support, pain control, and quality of life at all stages of disease.
