食管癌 中国就医指南

Esophageal cancer is a malignant neoplasm arising from the epithelial lining of the esophagus—the muscular tube connecting the pharynx to the stomach. It is broadly classified into two histological subtypes: esophageal squamous cell carcinoma (ESCC), predominant in the upper and middle thirds and strongly associated with smoking, heavy alcohol use, and dietary carcinogens (e.g., nitrosamines, thermal injury from hot beverages); and esophageal adenocarcinoma (EAC), which arises predominantly in the distal esophagus and is closely linked to chronic gastroesophageal reflux disease (GERD) and Barrett’s esophagus—a metaplastic change where normal squamous epithelium is replaced by columnar epithelium. Pathogenesis involves progressive accumulation of genetic alterations (e.g., TP53 mutations, CDKN2A inactivation, ERBB2 amplifications) driven by chronic inflammation, oxidative stress, and impaired DNA repair mechanisms. Globally, esophageal cancer ranks sixth in incidence and fifth in cancer-related mortality, with over 600,000 new cases and 540,000 deaths annually (GLOBOCAN 2022). Incidence varies markedly by region: ESCC dominates in the 'Asian Esophageal Cancer Belt'—stretching from northern Iran through Central Asia to northern China—where rates exceed 15–30 per 100,000 person-years; EAC is more common in Western countries, particularly among white males in North America and Northern Europe. Key modifiable risk factors include tobacco smoking (2–5× increased risk), excessive alcohol consumption (especially when combined with smoking), poor nutrition (low intake of fruits/vegetables, micronutrient deficiencies), obesity (for EAC), and habitual consumption of very hot beverages (>65°C). Non-modifiable risks include male sex (3–4× higher incidence), age (>55 years), achalasia, tylosis, and prior head/neck cancers. Early-stage disease is often asymptomatic; dysphagia (initially for solids, progressing to liquids), unintentional weight loss, odynophagia, and retrosternal pain are hallmark late symptoms—leading to frequent diagnosis at advanced stages. This significantly impairs quality of life: patients experience malnutrition, dehydration, social withdrawal due to eating difficulties, anxiety about prognosis, and reduced functional independence. Palliative interventions—including stent placement or feeding tube insertion—may alleviate symptoms but do not reverse systemic decline. Psychosocial burden is high, with elevated rates of depression and caregiver strain. Multidisciplinary management involving gastroenterologists, oncologists, thoracic surgeons, radiation oncologists, and nutritionists is essential to optimize survival and preserve dignity throughout the disease trajectory.
