Priya Dedhia, MD, PhD
SUS Sponsor: Allan Tsung. MD
Research mentor: Matthew Ringel, MD; William Carson, MD
Project: Wnt and IGF2 in adrenocortical carcinoma metastatic progression
Dr. Priya Dedhia, MD, PhD is an Assistant Professor in the Division of Surgical Oncology at The Ohio State University. As an endocrine surgeon, her clinical and research efforts focus on improving treatment options available to patients with endocrine thyroid, parathyroid, and adrenal disease. Her background in cancer biology and generation of patient-derived organoids uniquely positions her to develop models for difficult to study endocrine cancers.
Dr. Dedhia completed her MD and PhD at University of Pennsylvania, where she used cell lines and mouse models to study mechanisms of oncogenesis in acute myeloid leukemia. This experience provided her with a strong foundation and framework to study oncogenic transformation. During her General Surgery residency at the University of Michigan, she generated and characterized 3-dimensional organoid models from pluripotent stem cells and from primary patient tissues. This work, which was supported by the American College of Surgeons Resident Research Award, showed that organoids retain many features of the original tumor and can provide unique biological insights that are lacking in 2-dimensional culture systems or mouse models.
Using these experiences, she has developed organoid models of adrenocortical carcinoma and medullary thyroid cancer. This proposal focuses on determining the contribution of Wnt and IGF2, poncogenic pathways known to be dysregulated in adrenocortical carcinoma, in metastatic progression using a novel in vitro metastasis platform. Dr. Dedhia’s long-term goal is to develop patient-derived tumor organoids to predict responses to different chemotherapeutic agents and to identify tailored treatment regimens for each patient.

Philip Spanheimer, MD
SUS Member Sponsor: Ronald Weigel, MD
Research Mentor: Charles Perou, MD
Project: TFAP2C Regulates Estrogen Responsive Transcriptomic States in Luminal Breast Cancer
Dr. Spanheimer graduated from Duke University and the University of Iowa College of Medicine. He did his General Surgery Residency at the University of Iowa including a T32 research fellowship. Following residency, he completed a Complex General Surgical Oncology fellowship at Memorial Sloan Kettering Cancer Center. He is currently an Assistant Professor of Surgery in the Division of Surgical Oncology and Endocrine Surgery and a member of the breast cancer research group in Lineberger Comprehensive Cancer Center at the University of North Carolina at Chapel Hill. This proposal focuses on regulation of estrogen response and distinct gene expression patterns at the single cell level within heterogenous breast cancers. He will be mentored by Dr Charles Perou, who was the first to describe breast cancer subtypes based on gene expression patterns, and focuses on using genomics, genetics, and cell biology to characterize the biological diversity of human tumors and develop improved treatments that are specific for tumor subtype and for each patient. Dr Spanheimer believes that a granular understanding of regulation of global expression patterns resulting in key phenotypic traits, such as estrogen response, will identify mechanisms of resistance to therapy, patients at risk for treatment failure, and provide targets for novel therapeutics.
2019-2020
Alex Cuenca, MD, PhD
Mentor: James Markmann, MD
SUS Member Sponsor: James Markmann, MD
Project: The role of adjuvant induced myeloid-derived suppressor cells in allograft tolerance.
Following graduation from New College of Florida, Dr. Cuenca completed both his medical school and general surgery residency at the University of Florida College of Medicine. He obtained a PhD in Microbiology and Immunology with a dissertation focused on the neonatal innate immunity and sepsis during his research hiatus from clinical training, as well as an NIH F32 grant to support his efforts. Following the completion of his general surgery residency, he subsequently completed a pediatric surgery fellowship at Boston Children’s Hospital. Due to his interest in pediatric hepatobiliary disease, immunology, and transplant surgery, he ultimately decided to pursue an abdominal transplant surgery fellowship and will complete his clinical training at Massachusetts General Hospital (MGH) in July of 2019. He will start as an assistant professor of surgery in August of 2019 at Boston Children’s Hospital, where he will continue the work that he started at MGH.
The focus of the proposal will be on the role of innate immunity in allograft tolerance. As innate immunity coordinates the adaptive immune response towards either allograft rejection or tolerance, the goal of the study will be to determine if an adjuvant can be administered to condition the transplant recipient towards a more tolerogenic state. His mentor and SUS sponsor for this project is Dr. James F Markmann, a NIH funded surgeon-scientist and expert in transplant immunology at MGH. Ultimately, Dr. Cuenca’s vision is to expand this work to examine other adjuvants that may be used to augment innate immune suppressor cell populations in order to promote transplant tolerance and decrease the overall burden of necessary but deleterious immunosuppressive medication regimens.
