Imaging of Neuroendocrine Tumors
and Obstacles to Diagnosis

In the past few decades, the overall incidence of neuroendocrine tumors (NETS) has increased, partly because of improved detection rates.1 Nevertheless, patients typically experience long delays of usually 5-7 years before diagnosis of NETs, as these tumors display an array of symptoms and there is a lack of sensitive and specific methods for early detection.2 Approximately 20% of patients with NETs have metastatic disease at presentation, and in half of those patients the primary tumor is not located at initial imaging.1 Most patients lack access to the multidisciplinary early care necessary for optimal management of these complex tumors.

There are an increasing number of new treatment modalities that may result in a better quality of life and longer survival of NETs patients. This lecture will discuss the pivotal role diagnostic imaging plays in the assessment of NETs and in monitoring response to therapy. The role of multidisciplinary collaboration, critical for optimal patient management, will be emphasized.1

  2. Oberg K, Castellano D. Current knowledge on diagnosis and staging of neuroendocrine tumors. Cancer Metastasis Rev. 2011;30:Suppl 1:3-7.

At the conclusion of this activity, participants should be better able to:

  • Discuss the array of symptoms by which neuroendocrine tumors (NETs) can present, as well as the multiple locations NETs typically occur.
  • Identify a provisional diagnosis of NETs when patients present with nonspecific complaints that cannot be resolved or complaints that are lumped into a syndrome.
  • Describe the diagnostic tools necessary to confirm the presence of NETs.

This activity has been planned and implemented in accordance with the Essential Areas and policies of the Accreditation Council for Continuing Medical Education through the joint sponsorship of Postgraduate Institute for Medicine and the International Center for Postgraduate Medical Education. The Postgraduate Institute for Medicine is accredited by the ACCME to provide continuing medical education for physicians.

Dr. Liu performed his undergraduate studies at Harvard University and received the A.B. degree, magna cum laude, in Biochemistry. He obtained his medical degree at Columbia University’s College of Physicians and Surgeons in New York, NY. Dr. Liu completed a research fellowship in the Islet Transplantation Program at New York Presbyterian Hospital, where he also completed his residency in Surgery. In addition, he completed a clinical research fellowship at the National Institutes of Health, National Institute of Diabetes and Digestive and Kidney Disease in Bethesda, MD.

Dr. Liu was recruited to Vanderbilt in 2009 to develop the Neuroendocrine Center. Prior to opening the center, he studied with renowned neuroendocrine surgeon Kjell Oberg, MD, PhD, in Sweden, who was perfecting the use of radioactive imaging tracers that offered patients exciting new treatment options. Under Dr. Liu’s direction, the Vanderbilt center consists of a coalition of scientists and clinicians working together to provide patients with the most innovative and comprehensive diagnostic tools, as well as treatment therapies that provide the best possible patient outcomes. In October of 2011, he was elected to the Executive Board of the North American Neuroendocrine Tumor Society.

Dr. Liu’s clinical interests include all aspects of surgical oncology and endocrine surgery with an emphasis on the treatment of neuroendocrine and carcinoid tumors, gastrointestinal, and endocrine diseases. His research interests have focused on islet transplantation and imaging of the beta cell for the diagnosis and treatment of diabetes. Dr. Liu has also worked extensively in immunology and transplantation.

Dr. Liu is well-published in his areas of research and clinical expertise, and has received several awards for his research and teaching.
