Dr R. Saso
MD MPhil PhD

Haemato-Oncologist/Transplant Physician

Dr Saso was born, educated and medically trained in Yugoslavia. He worked in different university hospitals as a junior doctor at home and abroad (USA, UK) and completed his postgraduate studies at the Immunology Research Centre, University of Belgrade.

Going forward, he worked on studies in the field of haematology, immunochemistry and neuro-immunology. His research focused on defining and staging lympho-proliferative diseases, as well as acute leukaemias, CML, AA/PNH and MDS and he completed his training in internal medicine, haematology/oncology at home and abroad.

He spent a year as a British Council Scholar at St Thomas’ Hospital and RPMS at Hammersmith Hospital. In addition to gaining clinical experience, he furthered his studies in internal medicine and haematology. He also undertook research on the role of different lymphokines and soluble factors in antigen presentation and T-lymphocyte proliferation. Results of the research were presented at the annual BSI Congress.

After obtaining his doctorate, he was promoted to Assistant Professor in Internal Medicine/Haematology in 1991 at the University of Saints Cyril & Methodius, Skopje.

In 1992, supported by the British Council, he returned to the UK and continued his work and professional development in haemato-oncology, initially at St George’s, and since then, at several other leading UK teaching hospitals and cancer centres.

Dr Saso’s long-term interest is in haemato-oncology and bone marrow transplantation. During the course of his career he has introduced new treatment modalities and diagnostic methods in haemato-oncology. He also helped to establish and run the Anticoagulant Clinic at the Royal Brompton Hospital. He has published many papers in peer-reviewed journals and presented his work at international conferences and meetings (ASH, BSH, EBMT etc).

Dr Samir Agrawal

Barts Health NHS Trust and Barts Cancer Institute, Queen Mary University of London, London, UK

Samir Agrawal is a Senior Lecturer in Haematology at the Queen Mary University of London and a Consultant Haemato-Oncologist at St Bartholomew’s Hospitals and The Barts Health NHS Trust, London UK.

Dr Agrawal qualified at the University of Bristol, UK, trained at The Royal Marsden Cancer Hospital, London, UK, and was awarded his PhD in Tumour Immunology from the University of Paris, France. He is Director of the Stem Cell Laboratory of the Barts Health NHS Trust, and has an interest in diagnostic immunophenotyping. He was a winner of the NHS Innovator Award in 2006 for the introduction of new diagnostic tests for the diagnosis of human leukaemias.

Dr Agrawal’s clinical activities stretch across all areas of haematological cancers, ranging from intensive chemotherapy for acute leukaemia to outpatient non-intensive chemo-immunotherapy for lymphoid diseases, particularly chronic lymphocytic leukaemia (CLL) and other lymphoid malignancies. Dr Agrawal has designed, funded, and implemented studies on myelodysplastic syndromes, invasive aspergillosis and CLL. A former member of the UK CLL Trials Committee, he is a trustee for CLLSA (the patient-led support organisation for patients in the UK with CLL), as well as a NICE reviewer and the haemato-oncology representative on the UK IVIg initiative. He is a member of the European group (ECIL) for guidelines for infection management.

Dr Agrawal’s research activities are focussed on CLL biology and developing novel approaches to treating this incurable disease; and improving patient experience with the development of the “remote patient monitoring programme”, which allows specialist follow-up without requiring attendance at the hospital. His current activities in the field of invasive fungal disease include a diagnostic study of high-risk haematology patients looking at improved and earlier diagnosis. He is also working to develop clinical guidelines and integrated care pathways for managing infection in the high-risk haemato-oncology setting and to promote best practice and highlight new developments through educational meetings.

Dr Agrawal has published over 70 papers in journals such as the Journal of Clinical Investigation, Journal of Immunology, Blood, the British Medical Journal, and the Journal of Clinical Oncology.

Dr Padman Vamadevan

Dr Padman Vamadevan undertook a Natural Sciences degree at Queens’ College, Cambridge, and subsequently completed his medical degree on the fast-track programme at Guy’s, King’s and St Thomas’ School of Medicine in London. He subsequently secured an Academic Foundation training post at Guy’s & St Thomas’ Hospitals, during which he was seconded to Quintiles Drug Research Unit where he was involved in trial design and management and data analysis.

Following this, he was appointed as an Academic Clinical Fellow in Clinical Pharmacology at St George’s Hospital and during this period, published multiple peer-reviewed papers, whilst also receiving a travel fellowship to speak at the European Respiratory Society congress. Subsequently, he has taken up a variety of Haematological and Oncological posts at a variety of leading cancer institutions in London, which have afforded him significant relevant clinical experiance.

He has worked at the Care Oncology Clinic for over two years, and his familiarity with Biochemistry, Clinical Pharmacology, Clinical Research Studies and Oncology are consistent with the academic lineages that underpin the metabolic treatments offered by the clinic.

Dr. Rodney Dean Larson

Dr. Larson was born and raised in the upper mid-west of the USA. He received his undergraduate degree from the University of North Dakota. He continued at UND School of Medicine for 2 years of medical school before transferring and finishing a Doctor of Medicine at Michigan State University. Returning to North Dakota he completed a residency training in Family Practice and then spent nearly his entire career working in the state of South Dakota with the Indian Health Service and the Veterans Administration of the US Government. His current practice and interest in Emergency Medicine stems from working part time in the ER of both institutions.

Personal contact and rapport with patients has always been a plus in his style of practice. He has a special interest in how medications work, including alternative or off label uses for medication. Of particular interest are retroactive studies which demonstrate that many medications already in use for common illness can have significant effect on treatment and prevention of nearly all forms of cancer stem cell lines. Dr. Larson is interested in integrating these medications with patients’ lifestyles.

The belief that additional forms of treatment can be effectively combined with current standard therapies for various cancers is rapidly becoming accepted by large cancer treatment centers. Dr Larson has a personal stake in the use of these concepts and derives satisfaction from being involved with patients who wish to explore additional evidence-based strategies to help manage their disease.

Dr. Daniel Thomas, DO, MS

Dr. Thomas earned his medical degree from Des Moines University and served his hospital intern-ship at Northwest General Hospital in Milwaukee, Wisconsin. Because medical education only begins in medical school, he didn’t stop there. In addition to a medical degree, Dr. Thomas earned a post-doctoral Master of Science degree in Metabolic and Nutritional Medicine from the University of South Florida College of Medicine. This advanced degree provided a deeper understanding of cellular biochemistry and human physiology than was taught in medical school.

The Master’s degree gave Dr. Thomas a greater understanding of the intimate connections between aging and disease, and metabolic dysfunction and faulty nutrition. It allowed him to provide even better care to his patients by giving him the knowledge on how to use the science of metabolic and nutritional medicine to prevent and reverse age-related diseases (including cancer), and stimulate metabolism, immunity, and cellular rejuvenation. Out of the 900,000 physicians in the United States, less than 0.01% have this important and cutting-edge degree.

In addition to a Master’s degree, Dr. Thomas has a post-doctoral Graduate Certificate in Metabolic Endocrinology and another in Clinical Neuroscience—both from the University of South Florida College of Medicine. This was followed by a Fellowship in Integrative Cancer Therapy with the Metabolic Medical Institute. Dr. Thomas also has a Bachelor of Science degree in Biochemistry from Andrews University as well as a Certificate in Plant-Based Nutrition from Cornell University. He is currently serving a two-year Fellowship in Advanced Metabolic Cardiology.
