Research

Social determinants of health (SDOH) may worsen cancer disparities. The Penn Individualized Management for Patient-Centered Targets (IMPaCT) model is a standardized community health worker intervention for addressing health inequity and SDOH, with proven effectiveness in chronic disease management. The IMPaCT program has currently been scaled up to 50 organizations in 20 states and the Veterans Administration health system, but the effectiveness of this model has not been previously studied in patients with cancer. The goal of this proposal is to evaluate the effectiveness of IMPaCT on cancer stage distribution, missed oncology clinic appointment rates and cancer-related outcomes in patients previously enrolled in IMPaCT across the University of Pennsylvania Health System from 2013-2022, who received any cancer diagnosis following enrollment in IMPaCT. Additionally, Dr. Martei and her research group plan to pilot and evaluate implementation outcomes of a breast cancer-adapted community health worker program integrated into breast cancer care delivery, using the Implementation Mapping for Adaptation framework. 

Biography

Dr. Martei graduated from Harvard College and Yale School of Medicine. She completed her internal medicine training at the University of California, San Francisco, and hematology-oncology fellowship and Master of Science in clinical epidemiology at University of Pennsylvania. Dr.  Martei is currently a medical oncologist, an assistant professor of medicine, and the vice chief of diversity, inclusion and health equity in the Hematology-Oncology Division at the University of Pennsylvania. Her research is focused on implementation strategies for eliminating global disparities in breast cancer outcomes by optimizing high quality breast cancer therapy delivery in low-resource settings and among patients with complex co-morbidities.

This funding is critical for building preliminary data in an area of disparity and great need.” 

Research

Patients with breast cancer are thought to be intrinsically resistant to immune checkpoint inhibitors, in part, due to a suppressed tumor microenvironment (TME) by myeloid derived suppressor cells (MDSCs). Previous work by the Roussos Torres lab demonstrated in preclinical models that entinostat decreases MDSC suppression. A better understanding of mechanisms to overcome the immunosuppressive TME of breast cancer will provide a basis for more specific molecular and/or cellular targets. Dr. Roussos Torres will examine the molecular and cellular mechanisms regulating intra- and inter-tumoral MDSC response to entinostat as well as the contribution of entinostat-treated macrophages and dendritic cells on decreased MDSC suppressive function. These findings will be validated in samples collected from patients enrolled in a clinical trial (NCI-9844).

Biography

Dr. Roussos Torres received undergraduate degrees in microbiology, immunology and molecular genetics and dance, from the University of California at Los Angeles in 2005. She then received her medical and doctorate degrees (MD/PhD) from the Albert Einstein College of Medicine in 2012. She completed her internal medicine residency at the Hospital of the University of Pennsylvania in 2014, and a fellowship in oncology in 2018 at Johns Hopkins University. Dr. Roussos Torres became an assistant professor at Johns Hopkins University. She is currently an assistant professor at the University of Southern California in the Division of Oncology.

Research

Dysregulated immunoglobulin production and preexisting autoantibodies may contribute to autoimmune adverse events (AE) of immunotherapy (e.g., thyroid disease) and immune-mediated AEs of chemotherapy (e.g., peripheral neuropathy (CIPN)). This proposal aims to identify autoantibodies that are associated with therapy-induced immune-related AEs (irAEs) in patients with breast cancer. Dr. Blenman is set to: 1) determine if preexisting serum autoantibodies are associated with irAEs, and 2) determine if specific preexisting serum autoantibodies protein epitopes are associated with irAEs. This study has the potential to uncover biomarkers that can be used to forecast and monitor irAEs before, during, and after therapy to help guide treatments and evaluate survivorship.

Biography

Dr. Kim Blenman is an immunologist and clinical chemist who uses and develops novel software tools to understand the mechanisms responsible for disparities in disease pathogenesis and therapeutic response. In addition to an undergraduate degree in chemistry and a doctoral degree in immunology, she has a certificate in Drug Development and Regulatory Sciences from the University of California, San Francisco. She had the privilege of learning and working on drug discovery and clinical development at Procter & Gamble’s Pharmaceutical division as a senior scientist and as a global research director for autoimmune diseases, inflammatory bowel disease, and irritable bowel syndrome. She was also a Postdoctoral Fellow at the City of Hope Comprehensive Cancer Center in Duarte, California. Dr. Blenman is currently an Assistant Professor in the Yale School of Medicine Department of Internal Medicine Section of Medical Oncology and the Yale Cancer Center as well as in the Yale School of Engineering and Applied Science Department of Computer Science.

Research

Although lymph nodes play a critical role in the expansion of anti-cancer T cells, they are frequent sites of metastatic spread. Prior work by Dr. Jones and colleagues found that compression of blood vessels by breast tumors in lymph nodes is associated with impaired T cell entry into these metastatic tumors. In this project, Dr. Jones and his group will test the hypothesis that relieving this compression will improve T cell entry into nodal metastases. They will use long-term intravital imaging to measure whether decompressing blood vessels enhances T cell entry into metastatic tumors. Further, they aim to combine decompression therapy with immune therapy to test whether this drug combination will enhance the killing ability of T cells that enter lymph node tumors.

Biography

Dr. Jones obtained his PhD in Immunobiology from Yale University, where he studied basic mechanisms of lymphatic vessel expansion during pathological inflammation. He completed his postdoctoral training at Massachusetts General Hospital/Harvard Medical School, where he developed mouse models of lymphatic metastasis and characterized tumor progression in lymph nodes. He is currently an assistant professor at the Boston University School of Medicine in the Department of Pathology and Laboratory Medicine. His lab studies immune suppressive mechanisms within metastatic tumors with the goal of identifying novel targetable proteins for effective therapy of advanced breast cancer.

Research
Breast cancer stem cells can emerge as a result of MYC-induced reprogramming of committed cell types (such as luminal epithelial cells in the mammary duct). Emerging evidence points to the role of super-enhancers in this reprogramming. The transcriptional coactivator Mediator links super-enhancers to target promoters within large transcription hubs and promotes MYC activity at super-enhancers, suggesting that Mediator facilitates reprogramming. Dr. Saldivar has uncovered an unexpected link between large transcription hubs and ATR, a replication stress-response kinase that is needed for MYC-driven cancers. His group will use a combination of time-lapse confocal imaging and single-cell sequencing to uncover a potential oncogenic role of ATR signaling within these hubs during MYC-induced reprogramming and breast cancer stem cell emergence.

Biography
Dr. Saldivar received his PhD at Ohio State University, where he studied the origins of genomic instability in premalignant cells. He completed his postdoctoral work at Stanford University, where he uncovered a cell cycle checkpoint pathway controlling the S to G2 transition. He is currently an assistant professor in the Division of Oncological Sciences and a member of the Cancer Early Detection Advanced Research Center at Oregon Health & Science University. His lab studies the mechanisms driving reprogramming in the early stages of cancer.
