Samuel Jacobs, MD

NSABP, University of Pittsburgh Hillman Cancer Center


Samuel Jacobs, MD is a Clinical Professor in the Department of Medicine, University of Pittsburgh School of Medicine, and the Director of Medical Affairs for the National Surgical Adjuvant Breast and Bowel Project (NSABP).  Dr. Jacobs has a long and distinguished career as a clinical researcher in the fields of breast oncology and lymphoma, with a focus on adjuvant and neo-adjuvant therapy.


For the last four years, Dr. Jacobs has been intimately involved with the research efforts of the NSABP Foundation, Inc., which has more than 700 research sites in North America and an international network of oncology and research professionals. The NSABP pioneered breast cancer studies that led to the establishment of lumpectomy plus radiation over mastectomy as the standard surgical treatment for breast cancer and was also the first group to demonstrate that adjuvant therapy (treatment in addition to surgery) could alter the natural history of breast cancer, increase survival rates, and prevent recurrence using tamoxifen and raloxifene.


In addition to his work in oncology treatment protocols, Dr. Jacobs has also conducted considerable research on the logistics and management of the clinical trial process, particularly in oncology. He has led the efforts at the University of Pittsburgh Clinical Research Service to provide study development and implementation assistance, IRB processing, patient recruitment, study coordination, and specimen and data collection for all investigators conducting cancer-related studies at all UPMC Cancer Centers.

Keith Knutson, PhD

Mayo Clinic


Dr. Knutson's current interests and research focuses on the immunology and immunotherapy of breast and ovarian cancers, both the basic immunobiology and clinical translation, including clinical trials. The laboratory conducts research on cancer vaccines focuses on augmenting CD4 helper T cell immunity using peptide epitopes. These vaccine strategies are aimed at preventing the patients from relapsing after optimal conventional therapies. Adoptive T cell therapy is also being examined, a strategy that involves infusing high numbers of T cells into patients with active bulky malignancy.


In addition to his research, Dr. Knutson participates in and chairs several study sections; is Director of the Mayo Clinic Cancer Center Immunology and Immunotherapy Program; Co-director, Mayo Clinic Immune Monitoring Core; and Director, Ovarian Cancer Immunotherapy Program at Mayo Clinic.


Dr. Knutson received his Ph.D. from the University of Georgia in Physiology and Pharmacology in 1995 and completed two post-doctoral fellowships in immunology: One at the University of British Columbia; and the other at the University of Washington. He was a 2004 recipient of a Howard Temin Award from the National Cancer Institute.


Ian Krop, MD, PhD

Dana-Farber Cancer Institute


Ian Krop, MD is Assistant Professor, Department of Medicine, at the Dana Farber Cancer Institute at Harvard Medical School. He is a renowned leader in the field of breast cancer, with an extensive publication record focused on biomarker targeting for the improvement of clinical outcomes. Dr. Krop’s research goal is to identify novel predictive markers and therapeutic targets in breast cancer and translate these discoveries into clinically useful reagents. To accomplish this goal, he has established an ongoing collaboration with Dr Kornelia Polyak to use SAGE (Serial Analysis of Gene Expression) to identify genes important in the interaction between cancerous breast epithelial cells and tumor associated stromal cells. This technology has yielded a number of potential therapeutic targets including two chemokine receptor/ chemokine ligand pairs as well as several cathepsin family members, the expression of which is markedly dysregulated in either tumor epithelial cells and/or tumor associated stromal cells. His research laboratory is currently validating these proteins as potential targets through the use of small molecule inhibitors in in vitro and in vivo models of tumor-stromal interaction. In addition to this ongoing project, Dr. Krop is directing directing or co-directing several clinical trials with the aim of identifying novel molecular predictors of response to conventional chemotherapeutic and molecularly targeted therapies.


Dr. Krop is Board Certified in Internal Medicine and Medical Oncology. He received his medical training and conducted his residency at Johns Hopkins University School of Medicine, and completed his Fellowship in Hematology & Oncology at Dana-Farber/Partners CancerCare.
