Is esophageal cancer common?
In our center, we treat over 200 patients annually. In recent years, we have observed an increased incidence of esophageal cancer, especially in patients with adenocarcinoma.
-
What are the symptoms of esophageal cancer and what should we pay attention to?
In its early stages, esophageal cancer is usually asymptomatic. Patients often have symptoms related to risk factors such as gastroesophageal reflux disease (GERD), heartburn, and regurgitation. In advanced stages, dysphagia (difficulty swallowing) and chest pain are specific symptoms, along with general signs of cancer such as weakness, fatigue, weight loss, and chronic anemia.
-
Which groups of people are at the highest risk of developing esophageal cancer?
High-risk individuals can be divided into two groups. The first group includes patients at risk for squamous cell carcinoma, which typically develops in the upper part of the esophagus. The main risk factors here are smoking, excessive alcohol consumption, and HPV infection. The second group includes patients with esophageal adenocarcinoma, the incidence of which has increased by 400% in recent years. The main risk factors include GERD, obesity, and untreated gastric reflux, which can lead to precancerous conditions.
-
What are the modifiable and unmodifiable risk factors for esophageal cancer?
The main modifiable risk factor is gastroesophageal reflux disease. Modern medicine offers accurate methods for assessing the severity of the disease and a variety of treatment options.
-
Can food temperature or frequent throat infections increase the risk of esophageal cancer?
Shopman: It is not certain whether food temperature is an important risk factor, but countries with high consumption of hot food show a higher incidence of squamous cell carcinoma of the esophagus. Recurrent throat infections may be indirectly related to reflux disease, which is a risk factor.
-
How is esophageal cancer diagnosed?
The main diagnostic methods include gastroscopy, CT (PET) scans, and endoscopic ultrasound in some cases.

What are the treatment methods for esophageal cancer and what are the chances of a normal life after treatment?
Approximately 30% of patients with esophageal cancer are candidates for surgical treatment. Esophageal resection can be performed using minimally invasive techniques, but it is recommended that the surgery be performed in specialized clinics by experienced surgeons. Treatment in a multidisciplinary setting by a team of oncologists, surgeons, and gastroenterologists is crucial. Preoperative chemotherapy or radiation therapy significantly improves survival rates.
The classic operation involves removing part of the esophagus and sometimes lymph nodes. The esophagus is reconstructed with tissue from the stomach or colon. In more severe cases, part of the upper stomach may be removed. Risks include pain, infections, and pulmonary complications.
Chemotherapy uses drugs to destroy cancer cells and can be given before or after surgery. Possible side effects include nausea, vomiting, fatigue, and hair loss.
Radiation therapy uses radiation to kill cancer cells and is often combined with chemotherapy. Side effects include skin burns, painful swallowing, and fatigue.
Targeted therapies attack specific proteins in cancer cells that contribute to tumor growth.
If the esophagus is narrowed, a stent can be implanted to maintain its patency. Photodynamic therapy is another option, in which the tumor is treated with light after injection of a photosensitizing agent.

The risk of esophageal cancer can be reduced by: * **Quitting smoking:** Smoking is a major risk factor for esophageal cancer. * **Limiting alcohol consumption:** Heavy alcohol use increases the risk. * **Maintaining a healthy weight:** Obesity is linked to an increased risk. * **Eating a healthy diet:** A diet rich in fruits and vegetables may help protect against esophageal cancer. * **Managing GERD:** Gastroesophageal reflux disease (GERD), a condition where stomach acid flows back into the esophagus, is a risk factor. Treating GERD effectively can reduce the risk. * **Avoiding certain infections:** Infections with H. pylori (a bacterium) and HPV (human papillomavirus) have been linked to esophageal cancer. * **Being aware of occupational exposures:** Exposure to certain chemicals, like those found in asbestos or silica, may increase risk.
Risk reduction includes treatment of gastroesophageal reflux disease, avoiding smoking, limiting alcohol, a diet rich in fruits and vegetables, and maintaining a healthy weight.
