Endocrine Neoplasia


The Duke Endocrine Neoplasia Research Group is committed to providing high-quality research and training in the field of Endocrine Neoplasia. The group comprises surgeons, endocrinologists, radiation oncologist, residents, fellows, health services researchers, epidemiologists, psychologists, and biostatisticians. The multidisciplinary nature of this group makes it ideal to tackle the pressing issues of endocrine neoplasms and work toward bridging gaps in patient care at the individual and population levels.
Our research is focused on the different diseases of the thyroid, parathyroid, pancreas, and adrenal glands. Although our primary focus is health services research and health outcomes, we are also interested in examining different issues along the continuum of patient care, including translational research, clinical trials for novel therapies and patient repored outcomes, among others.
  • Health Services Research
  • Translational Research: The endocrine neoplasia group has an encompassing interest in cross-disciplinary translational research, including parathyroid diseases (Koh Laboratory), and thyroid cancer (Counter Laboratory; Stapleton Laboratory)  
  • Cancer Genetics: The endocrine neoplasia group has been working using genomic data of thyroid cancer, to develop a genetic signature that predicts progression. (Cheng Laboratory) 
  • Clinical Trials

Research Focus Areas

The Sosa laboratory is focused on the different diseases of the thyroid, parathyroid, pancreas and adrenal glands.

Although the primary focus is health services research and health outcomes, other areas of interest include examining different issues along the continuum of patient care, including translational research, the psychological and economic impact on patients of endocrine diseases and their subsequent treatment, and patients’ decisions regarding the different diagnostic and treatment strategies available to them. 

In conjunction with several collaborators at Duke, UNC and Yale, among others, the Sosa lab is involved in the development of novel drugs for advanced and unresectable thyroid cancer, cancer genomics, new technologies for the study of single cell physiology, point of care biochemical evaluations, and stem cell therapy for hypoparathyroidism.

Clinical Trials

Tissue and Serum Acquisition Protocol for Molecular Analysis and Cell Culture in Patients Undergoing Parathyroid Surgery
The state of knowledge in this field is very limited, and investigators are faced with developing a basic understanding of potential relationships between several thousand or tens of thousands of genes and their associations with outcomes. Acquisition of parathyroid tissue and serum specimens at the time of definitive surgery for parathyroid disease is a crucial prerequisite for present and future laboratory and translational scientific programs.

Role of NGS-based ThyroSeq Panel in Cancer Diagnosis in Thyroid Nodules
Targeted next generation sequencing (NGS) platforms allow testing for tens and hundreds mutational hotspots. Additional mutational mutations in thyroid cancer have been identified, and promising markers associated with tumor prognosis have been found. By participating in this multi-institutional study, we hope to assist in the validation of these markers.
Funding: University of Pittsburgh

Thyroid Cancer and Polybrominated Diphenyl Ether (PBDE) Exposure
Excessive environmental exposure of adult patients to PBDE chemicals is associated with the development of papillary thyroid carcinoma, and may account for the increasing incidence of thyroid cancer in the United States. Clinical-translational mechanisms are used to explore the association between PBDE exposure, serum PBDE levels, and thyroid cancer.

Randomized Double-Blind Phase II Study of Radioactive Iodine (RAI) in Combination with Placebo or Selumetinib for the Treatment of RAI-Avid Recurrent/Metastatic Thyroid Cancers
The study examines the response of tumors following treatment with radioactive iodine in combination with placebo or selumetinib for RAIA recurrent and/or metastatic thyroid cancer.
Funding: Academic and Community Cancer Research United

RIFTOS MKI – An Observational Study in Differentiated Thyroid Cancer Which is Radioactive Iodine (RAI) Refractory to Assess the Use of Multikinase Inhibitors
This is an international prospective, open-label, multi-center, non-interventional study designed to compare treatment options in DTC. Practice patterns of care of patients with RAI-refractory DTC under real-life conditions will be evaluated.
Funding: Bayer Healthcare

Eisai – An Open-Label, Single-Arm, Multicenter, Phase 2 Trial of Lenvatinib for the Treatment of Anaplastic Thyroid Cancer (ATC)
The study will evaluate the effectiveness and safety of lenvatinib, also known as LENVIMA™, (approved by the FDA February 13, 2015 in the U.S.) in patients with anaplastic thyroid cancer (ATC).  Lenvatinib may offer a new treatment option that will be more effective than the standard drugs used for ATC by stopping the formation of new blood vessels that help cancer cells grow and spread.  Lenvatinib is taken by mouth in capsule form and is to taken on a daily basis. Lenvatinib is a drug that was approved by the FDA (the U.S. Food and Drug Administration) on February 13, 2015 in the U.S. Funding: Eisai, Inc.
