What is esophageal cancer?
Esophageal cancer is a malignant tumor originating from the esophageal mucosa. It is highly invasive with a propensity for early metastasis. Typical symptoms include progressive dysphagia, retrosternal pain, and weight loss.
Main types of esophageal cancer
1.Squamous cell carcinoma
The most common type, accounting for approximately 85% of cases worldwide, and more prevalent in certain high-incidence regions such as China.
2.Adenocarcinoma
Often associated with Barrett’s esophagus. Its incidence has been increasing in Europe and the United States and is related to gastroesophageal reflux disease and obesity.
3.Other rare types
Including small cell carcinoma and adenosquamous carcinoma, which have heterogeneous biological behaviors and require different treatment strategies.
4.Molecular subtyping
Molecular subtyping based on genetic alterations and the tumor microenvironment is advancing the development of precision medicine.
Etiology of esophageal cancer
1.Tobacco and alcohol
Smoking and alcohol consumption are major risk factors. Their synergistic effects can markedly increase cancer risk.
2.Dietary habits
Long-term intake of very hot foods, pickled foods, and insufficient consumption of fresh fruits and vegetables are closely associated with esophageal cancer.
3.Gastroesophageal reflux disease
Chronic reflux can lead to Barrett’s esophagus, an important precancerous condition for esophageal adenocarcinoma.
4.Genetic and familial factors
Esophageal cancer shows familial aggregation; having a first-degree relative with the disease increases individual risk.
5.Other factors
Obesity, HPV infection, a history of head and neck tumors, and achalasia may also increase risk.
Conclusion
Jinshazhou Hospital of Guangzhou University of Chinese Medicine emphasizes that esophageal cancer is highly aggressive, and early diagnosis and standardized treatment are pivotal. A healthy lifestyle and regular examinations are recommended. Multidisciplinary comprehensive treatment, including minimally invasive surgery and targeted and immunotherapies, can substantially improve outcomes and quality of life.
