Surgery for Gastric Cancer – Essentials
It is very important to appropriately stage GC patients since it is associated with the choice of treatment modalities and patients’ prognosis. The current staging modalities include endoscopy, CT, PET/CT, and laparoscopy.
The primary goals of the staging are to evaluate whether a patient has regional or distant metastasis (M), whether the tumor involves local/regional lymph nodes (N), and whether the depth of tumor invasion into the different histology layers between mucosa and serosa (T).
Combining the three components, Union for International Control Cancer (UICC)/American Joint Committee on Cancer (AJCC) has defined the most commonly used GC staging system, tumor-node-metastasis (TNM) staging system.
