Esophageal cancer incidence is increasing across the developed world. Men are considerably more likely than women to develop the disease.
The two main histologic types are squamous cell carcinoma and adenocarcinoma. In the developed world, adenocarcinomas predominate.
Low socioeconomic status, smoking, excessive alcohol use, GERD, Barrett esophagus, and obesity are some of the main risk factors.
Tumors are often locally advanced at the time of diagnosis. Accurate staging is important for prognosis and treatment planning.
Superficial intramucosal esophageal cancer is best managed by endoscopic resection and surveillance. Early-stage cancers in surgical candidates are best treated by esophagectomy.
For locally advanced disease, combined modality therapy is considered the current standard. This involves chemotherapy or chemoradiation followed by surgery.
Targeted therapies can be used in patients with metastatic esophageal and esophageal junction cancer.
Treatment decisions for patients with recurrent or refractory disease are informed by prior treatment history.
Most esophageal cancers are neoplastic mucosal lesions that originate in the epithelial cells lining the esophagus.
Esophageal cancers are usually squamous cell carcinomas or adenocarcinomas.
Rarely, other cancers, such as melanoma, sarcoma, small cell carcinoma, or lymphoma, can occur in the esophagus.

limited disease (cT1, cN0, M0)
localized disease (cT2, cN0, M0): suitable for surgery
localized disease (cT2, cN0, M0): unsuitable for surgery
locally advanced disease (cT3-4, cN1-3, M0): suitable for surgery
locally advanced disease (cT3-4, cN1-3, M0): unsuitable for surgery
metastatic (M1) disease
- Benign stricture
- Barrett esophagus
- NCCN clinical practice guidelines in oncology: esophageal and esophagogastric junction cancers
