12 TNM scores
16 The 5 stages
Cancer staging is a rating by your
doctors of how far the cancer has
grown and spread. The rating is
based on test results. Doctors plan
additional tests and treatment based
on how much the cancer has grown.
In Part 2, the scoring system used for
cancer staging is explained.
The AJCC (
staging system is used to stage stomach cancer.
Tumors that occur in the EGJ are staged according to
esophageal cancers. Read the
NCCN Guidelines for
Patients: Esophageal Cancer
for more information.
In the AJCC system, the letters T, N, and M describe
a different location of cancer growth. Your doctors
will assign a score to each letter. TNM scores will
be combined to assign the cancer a stage. The
cancer stage is used to assess the prognosis of the
cancer and to decide what treatments will be used. A
prognosis is the outlook (prediction) of the pattern and
outcome of a disease.
