Cancer staging

Review

Review

• Esophageal cancer is grouped into stages.

• Cancer stages are defined by the TNM scores,

cancer grade, and sometimes tumor location.

• A pathologist assigns a cancer grade based on

how much the cancer cells look like healthy cells.

• The clinical stage is based on tests given before

any treatment. The pathologic stage is based on

the results of surgery.
