Speaker Profile
Biography
Dr. Velculescu led the first genome wide sequence analysis in human cancers, identifying key genes and pathways dysregulated in tumorigenesis. He developed methods for global gene expression analyses and coined the word transcriptome" to describe the patterns that could now be obtained in cancer and other cells. These analyses identified a variety of genes not previously known to be involved in neoplasia, including PIK3CA as one of the most highly mutated genes in human cancer. His team's discoveries have led to new FDA approved therapies against PI3K and IDH1, and diagnostic tests for comprehensive tumor profiling. More recently, his group has created noninvasive machine learning liquid biopsy approaches for early detection and monitoring of cancer patients. His work has provided new paradigms for understanding human cancer that have benefited patients worldwide. He has been a Founder and CoCEO of Personal Genome Diagnostics and is Founder and CEO of Delfi Diagnostics.

Biography
Health policy and payment expert, pulmonary physician, and lung cancer epidemiologist, Peter has devoted his career to repairing defects in the healthcare delivery system that impede access to high-quality cancer care and working to ameliorate healthcares cost crisis. His work spans seminal studies including that identification of racial gaps in lung cancer care, the development of the first lung cancer risk prediction model (the Bach model), lead authorship on multiple lung screening guidelines, and definitional work on pharmaceutical pricing and value. Peter previously served as Senior Adviser at the US Centers for Medicare Medicaid Services and mentor on many National Institutes of Health K awards. He has been elected to the National Academy of Medicine, American Society for Clinical Investigation, and the Johns Hopkins Society of Scholars.
Speaker Profile
Biography
Klaus Pantel is a global pioneer in liquid biopsy whose groundbreaking research established circulating tumor cells (CTCs) and micrometastases as clinically meaningful biomarkers. His work revealed how tumor cells disseminate early in cancer progression and provided the first evidence that these rare cells could guide prognosis and therapy monitoring. Pantels leadership extended beyond the lab with the founding of the European Liquid Biopsy Society, creating the infrastructure and collaborations needed to advance blood-based cancer detection worldwide. His contributions have transformed liquid biopsy from a research concept into a cornerstone of precision oncology, enabling earlier detection, real-time treatment monitoring, and more effective cancer care.
Talk
Early detection of cancer by multimodal liquid biopsy analysis
Early detection of cancer is one of the most challenging application of liquid biopsy with overarching goal to reduce cancer mortality. Here, I will discuss the concept of a multimodal liquid biopsy encompassing the broad range of blood biomarkers including cell-free DNA, proteins, RNAs, extracellular vesicles, metabolites as well as circulating tumor and host cells as exemplified in my EU-funded project PANCAID aimed to detect pancreatic cancer at its earliest stages.

Biography
Dr. Diaz is a physician-scientist at Memorial Sloan Kettering Cancer Center. His teams provided the first definitive evidence for using circulating tumor DNA as cancer biomarker for screening, monitoring, and detection of occult disease; and discovered the therapeutic link between immunotherapy and cancer genetics in patients with mismatch repair deficient tumors. This research led to the historic first pan-tumor FDA approval for any solid tumors with this genetic lesion and the first cancer study that resulted in a 100% complete response rate. He is the recipient of numerous recognitions for his work including the Waun Ki Hong Award for Outstanding Achievement in Cancer Research. He is Editor-in-Chief of Cancer Discovery and is an elected member of the Giants of Cancer Care, the AACR Fellows Academy, the American Society of Clinical Investigation, and the American Academy of Physicians. In 2021, Dr. Diaz was appointed by President Joseph Biden to the National Cancer Advisory Board.

Biography
Giordano Botta is the Co-Founder and CEO of Allelica Inc, where he drives the development and clinical implementation of multi-ancestry polygenic risk scores (PRS). Under his leadership, Allelica pioneered the first clinical multi-ancestry PRS test for Coronary Artery Disease (CAD), breast and prostate cancer, now used by leading healthcare systems. He focuses on cost-effectiveness analysis to ensure the long-term sustainability of PRS tests. Botta has overseen the creation of a software engine and the integration of genomic and clinical data from over one million individuals of diverse ancestries to develop and validate PRS. His primary interest is advancing the integration of PRS for CAD and common cancers into standard medical care, improving prevention and early intervention strategies.
