A genomic insertion variant activates immune escape in breast cancer

Research

Tumors can evade the immune system by intrinsically upregulating genes of immune evasion (e.g., CD47). However, it remains unknown whether mechanisms activating the immune evasion program in cancer cells are patient-specific. This information is key for generating tailored treatments to recruit the immune system for the eradication of cancer. Super-enhancers are long genomic regions that have potent gene regulatory activity and are critical for the upregulation of immune suppressive genes within breast cancer cells. This proposal aims to determine whether an eight-base pair binding motif, encoded by a patient-specific genomic insertion, actives a super-enhancer-driven program of immune evasion through the dual regulation of CD47 and the long intergenic non-coding regulatory gene 00636 (LINC00636). Therefore, this insertion could be a signature of tumor immune escape and, consequently, progression in patients carrying this genomic variant.

Race-aware multimodal data integration for outcome models in breast cancer

Research

Dr. Sanchez-Vega’s team will create and analyze a comprehensive multimodal database for a racially diverse population of 1,600 locally advanced breast cancer patients treated with neoadjuvant chemotherapy. This database will include comprehensive clinical information, as well as digitized pathology slides, magnetic resonance images, and targeted DNA sequencing data. This cohort will be used to build race-informed multimodal machine learning algorithms that predict complete pathological response to neoadjuvant therapy. Dr. Sanchez-Vega will investigate the predictive performance of individual data modalities when patients are stratified by race and relevant molecular subtypes. His team will design deep learning models that integrate multiple data modalities in a race-informed manner and optimize them to generalize to diverse real-world populations. The database and computational pipelines generated will be made publicly available to facilitate long term development of multimodal methods that further improve predictive and prognostic capabilities for breast cancer patients.

Biography

Dr. Sanchez-Vega earned his doctorate in applied mathematics and statistics, with an area of specialization in computational medicine, from Johns Hopkins University. He is currently an assistant attending in the computational oncology service of the Department of Epidemiology and Biostatistics at Memorial Sloan Kettering. Dr. Sanchez-Vega’s research focuses on translational applications of machine learning, statistical modeling, and computational methods to the field of cancer genomics and precision oncology. His group is also interested in the use and implementation of novel computational approaches for multimodal integration of genomic sequencing data and orthogonal sources of biological and clinical information.

Effectiveness of community health workers on access to breast cancer care

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.

Suppressing suppression: myeloid centric approach to an anti-tumor response

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.

Characterization of pre-existing autoantibodies in breast cancer

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.

Improving anti-breast cancer immunity by targeting solid stress

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.
