What is gastric carcinoma or AEG in localized and resectable (surgically removable) stages?

Gastric carcinoma is a malignant tumor of the gastric mucosa. The so-called AEG (adenocarcinoma of the gastroesophageal junction) develops in the area between the esophagus and the stomach. In resectable, i.e., operable stages, the tumor is still limited and can be completely removed.

Common complaints include:

• Loss of appetite
• Early feeling of fullness
• Upper abdominal pressure
• Weight loss
• Blood in stool

Since the symptoms are nonspecific, the diagnosis is often made by chance. Stomach cancer has become less common in Switzerland, but it still mainly affects older people.

Treatment usually consists of surgery—combined with immunochemotherapy before and/or after the procedure. In certain cases, surgery is supplemented with cytoreductive surgery and HIPEC. The key decision-making step in treatment is the tumor board meeting prior to initiating therapy, in order to determine the appropriate treatment strategy. The goal is to prevent recurrence and improve the chances of cure. If the cancer is detected at an early stage, the prognosis is good.

It is important to follow a tailored diet after the operation and to receive good aftercare.
