Esophageal cancer is a disease in which abnormal cells form in the tissues of the esophagus or the food pipe. The food pipe connects the mouth to the stomach.

Esophageal cancer grows slowly and may grow for many years before the symptoms are felt. However, once the symptoms develop, esophageal cancer progresses rapidly. As the tumor grows, it can seep into the deep tissues and organs near the esophagus. It is the sixth most common cause of cancer deaths worldwide, and it affects more men than women.

Often, the lower esophageal cancer may have “Barrett esophagus” as an underlying condition. This is a condition in which the lower part of the esophagus becomes red and swollen due to continuous irritation by gastric juices over time.

What are the types of esophageal cancers?

Esophageal cancer is classified according to the type of cells that are involved. The type of esophageal cancer helps to determine the appropriate treatment options. Types of esophageal cancer include:

Stages of esophageal cancer

The staging system most often used for esophageal cancer is the TNM system of the American Joint Committee on Cancer (AJCC), which is based on three key pieces of information:

  • The extent (size) of the tumor (T)
  • The spread to the nearby lymph nodes (N)
  • The spread (metastasis) to distant sites (M)

The grade of the tumor describes how abnormal the cancer cells look under a microscope and how quickly the tumor is likely to grow and spread. Grades I to III are used to describe esophageal cancer.

What are the signs and symptoms of esophageal cancer?

There may be no signs or symptoms in the early stages. However, in more advanced esophageal cancer, the following symptoms are seen:

What causes esophageal cancer?

Esophageal cancer occurs when cells in the esophagus develop changes (mutations) in their deoxyribonucleic acid (DNA). The changes allow cells to grow and divide out of control. The accumulating abnormal cells form a tumor in the esophagus that can grow to invade nearby structures and spread to other parts of the body. The exact cause of the mutations is not known. Several factors increase a person's risk of developing esophageal cancer. These include

  • Smoking or other use of tobacco
  • Heavy alcohol use
  • Gastroesophageal reflux disease (GERD), which is a condition where the contents and acid from the stomach go back up into the esophagus
  • Poor nutritional status
  • Barrett’s esophagus, which is a condition that affects the lower part of the esophagus and can lead to esophageal cancer. Barrett’s esophagus may be caused by GERD. Over time, stomach acid in the esophagus can cause changes in the cells that increase the risk for adenocarcinoma.

How is esophageal cancer diagnosed?

The diagnosis of esophageal cancer is made after reviewing the symptoms, medical history and performing examinations. Also, certain diagnostic tests are conducted to make a definitive diagnosis and determine if the cancer has spread or metastasized outside of the esophagus. The important tests include

How is esophageal cancer treated?

Treatment of esophageal cancer depends on many factors, including the stage of cancer and the overall health of the patient. The treatment options are

  • Surgery: A part or whole esophagus may be removed.
  • Radiation therapy: Radiation is used to kill cancer cells.
  • Chemotherapy: Powerful drugs that attack cancer cells throughout the body. Typically, this is used in combination with radiation therapy and/or surgery.
  • Targeted therapy: Newer treatments that target specific aspects of cancer to curb cancer growth and spread.
  • Immunotherapy: This therapy influences the immune system to attack cancer cells.
  • Photodynamic therapy: This therapy targets cancer cells with special laser light.
  • Electrocoagulation: This uses electric current to destroy cancer cells.
  • Cryotherapy: This procedure freezes cancer cells to help shrink a tumor.
  • Endoscopic mucosal resection: This may be done to treat precancers, very small or early cancers. This procedure removes the inner lining of the esophagus.
  • Radiofrequency ablation treatment: This is done using a device that targets cancer cells with radiofrequency energy. This is sometimes used for early cancers.
