2B70.0 Adenocarcinoma of oesophagus
Definition of Adenocarcinoma of oesophagus: A malignant tumour with glandular differentiation arising predominantly from Barrett mucosa in the lower third of the esophagus. Grossly, esophageal adenocarcinomas are similar to esophageal squamous cell carcinomas. Microscopically, adenocarcinomas arising in the setting of Barrett esophagus are typically papillary and/or tubular. The prognosis is poor.
2B70.00 Barrett adenocarcinoma
Definition of Barrett adenocarcinoma: Barrett adenocarcinoma is defined as adenocarcinoma of lower oesophagus and gastroesophageal junction associated with Barrett’s oesophagus.
2B70.0Y Other specified adenocarcinoma of oesophagus
2B70.0Z Adenocarcinoma of oesophagus unspecified
2B70.1 Squamous cell carcinoma of oesophagus
Definition of Squamous cell carcinoma of oesophagus: A squamous cell carcinoma arising from the esophagus. It can be associated with a long history of tobacco and alcohol abuse and is exceedingly rare before the age of 30. The median age is around 65 in both males and females, but the incidence in males is much higher than in females. It is located mostly in the middle and lower third of the esophagus. Grossly, polypoid, ulcerated, plaque-like and occult lesions have been described. The microscopic features are the same as in other squamous cell carcinomas. Any degree of differentiation may occur, and variation within a single tumour is common. The prognosis is poor.
2B70.Y Other specified malignant neoplasms of oesophagus
2B70.Z Malignant neoplasms of oesophagus unspecified
Definition of Malignant neoplasms of oesophagus unspecified: Malignant neoplasms that arise from the cells of the oesophagogastric junction (OGJ), which is defined as the point at which the oesophagus ends and the stomach begins. This mainly defines adenocarcinomas that straddle the junction of the oesophagus and stomach. This definition includes many tumours formally called cancers of the gastric cardia.

2B71 Malignant neoplasms of oesophagogastric junction
Exclusions:
- Malignant mesenchymal neoplasms
2B71.0 Adenocarcinoma of oesophagogastric junction
Definition of Adenocarcinoma of oesophagogastric junction: An adenocarcinoma that arises from and straddles the junction of the stomach and esophagus. The category of adenocarcinomas of the gastroesophageal junction also includes the majority of adenocarcinomas previously called gastric cardia adenocarcinomas. Squamous cell carcinomas that affect or cross the junction of the stomach and esophagus are classified as carcinomas of the distal esophagus. Adenocarcinoma of the gastroesophageal junction occurs more often in Caucasian middle aged and elderly males. Clinical signs and symptoms include dysphagia, abdominal pain, and weight loss. The prognosis depends on the completeness of the surgical resection, the number of lymph nodes involved by cancer, and the presence or absence of postoperative complications.
2B71.Y Other specified malignant neoplasm of oesophagogastric junction
2B71.Z Malignant neoplasms of oesophagogastric junction unspecified
Definition of Malignant neoplasms of oesophagogastric junction unspecified: A primary or metastatic malignant neoplasm involving the stomach.

- Gastrointestinal stromal tumour of stomach (2B5B.0)
2B72.0 Adenocarcinoma of stomach
Definition of Adenocarcinoma of stomach: An adenocarcinoma arising from the stomach glandular epithelium. Gastric adenocarcinoma is primarily a disease of older individuals. It most commonly develops after a long period of atrophic gastritis and is strongly associated with Helicobacter pylori infection. The lack of early symptoms often delays the diagnosis of gastric cancer. The majority of patients present with advanced tumours which have poor rates of curability. Microscopically, two important histologic types of gastric adenocarcinoma are recognised: the intestinal and diffuse type. The overall prognosis of gastric adenocarcinomas is poor, even in patients who receive a curative resection.
2B72.1 Malignant neuroendocrine neoplasm of stomach
Definition of Malignant neuroendocrine neoplasm of stomach: A neoplasm with neuroendocrine differentiation that arises from the stomach. It includes well differentiated neuroendocrine tumours (low and intermediate grade) and poorly differentiated neuroendocrine carcinomas (high grade).
