NCCN Guidelines for Patients
Esophageal Cancer, Version 1.2016
• 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.
