Cancer Coaching-When Is EUS Necessary for a Newly Diagnosed Cancer of the Esophagus, Stomach, Colon, or Pancreas?

If you have been diagnosed with either Esophageal,┬áStomach, Colon, or Pancreatic cancer determining an accurate stage of your cancer is critical. It is your cancer’s stage that determines your therapy plan and prognosis. So the real question is not when is EUS necessary but when is it not necessary for newly diagnosed patients?

An important issue for cancer patients is to determine if their oncologist and the associated cancer center, is well-versed in your type and stage of cancer. The local community hospital may not have handled many cases of your specific type of cancer.

Your community hospital may not offer certain types of diagnostic testing required give you the important information that you need.

I am both a cancer survivor and cancer coach. Have you been diagnosed with cancer? What type? What stage? My mission is to provide cancer patients with the information they need to manage their cancer. Please scroll down the page, post a question or comment and I will reply to you ASAP.

Thank you,

“A: Gastrointestinal endoscopic ultrasound (EUS) is an important tool for cancer staging because many treatment algorithms are determined by EUS tumor staging…

Computed tomography (CT) scan should generally be obtained before EUS to determine whether there is any metastatic disease that would make the patient a nonsurgical candidate…

If there is no evidence of metastatic disease, then EUS should be performed for locoregional staging. The tumor-node-metastases (TNM) staging system is used for luminal GI and pancreatic cancer. The EUS accuracy for staging GI and pancreatic cancer is approximately 85% for T-staging and 75% for N-staging

The time to use EUS in cancer staging is before the patient receives any chemoradiation. Staging accuracy significantly decreases after chemoradiation because EUS cannot distinguish between peritumoral inflammation/edema and the actual tumor…
