Gastrointestinal Neuroendocrine Tumors: Prediction Tools

Our gastrointestinal stromal tumor nomogram is an online tool that can be used to predict the chance that patients will survive without their cancer returning after receiving surgery alone, without receiving post-surgery chemotherapy.

Who Can Use This Tool?

This nomogram was designed to be used by physicians and people with gastrointestinal stromal tumors. If you are a patient, we recommend that you use this tool in consultation with your doctor.

Why Is This Tool Useful?

Having an accurate prognosis is important because it can help patients and their physicians evaluate the best treatment plan following surgery.

What Information Will You Need?

In order for this nomogram to provide an accurate prediction, you must include accurate values for all of the information below.

  • Tumor size: From 0.001 to 20 cm.
  • Tumor site: Stomach, colon, rectum, or small intestine.
  • Mitotic index: Whether the mitotic index (i.e., the number of cells in the mitotic phase of the cell cycle) was listed as greater than or equal to 5 per 50 HPF on the pathology report.

To better understand the results of the nomogram, patients should discuss survival estimates with their doctors.
