Hi, I am reading your posts with interest. I have a 4x3 cm neuroendocrine metastatic tumor in my liver and another one on the other lobe. I have no symptoms at this time. KI 67 6-8%, well differentiated. They suspect the origin is in the GI track but since I have no symptoms & they do not feel additional testing is required or treatment. I have not been given any information on what I should expect in the future. This info was from an e consult with Mayo Clinic. I am considering whether I should get a second opinion with MD Anderson. Dr Daniel Halperin is now employed at Emory in Atlanta where I live. Appreciate your sharing your journey.
