TNM system for stomach cancer
Making an educated treatment decision begins with the stage, or progression, of the disease. The stage of stomach cancer is one of the most important factors in evaluating treatment options.
Our cancer doctors use a variety of diagnostic tests to evaluate stomach cancer and develop an individualized treatment plan. If you have been recently diagnosed, we will review your pathology to confirm you have received the correct diagnosis and staging information, and develop a personalized treatment plan. If you have a recurrence, we will perform comprehensive testing and identify a treatment approach that is suited to your needs.
The American Joint Committee on Cancer (AJCC) developed the TNM staging system for evaluating the extent and spread of stomach cancer. The staging process is a basis for selecting treatment options and helping doctors communicate potential outcomes (prognosis). The TNM system considers three important factors:
- T - Describes the size and growth of the primary stomach tumor.
- N - Provides information about stomach cancer found in regional lymph nodes.
- M - Indicates whether the cancer has metastasized, or spread to other areas.
Each of these categories are rated on a numbered scale, the higher the number indicates increased severity. These categories are then grouped into stomach cancer stages from 0-IV.
