About

Dr. Mohamed L. Sorror is a board-certified hematologist-oncologist and clinical researcher at Fred Hutch focused on improving care for older and medically complex patients with blood cancers. 


Background

Dr. Sorror is a blood and marrow transplant (BMT) specialist whose work centers on improving care for patients with aggressive blood cancers, particularly those who are older, frail or have other medical conditions. He specializes in both autologous stem cell transplantation, which uses a patient’s own cells, and allogeneic transplantation, which uses cells from a compatible donor. 

Much of Dr. Sorror’s career focuses on clinical research designed to help patients and their physicians make better, more personalized treatment decisions. He and his colleagues pioneered the first widely used scoring system to predict the risks of stem cell transplantation for an individual patient. He also integrated geriatric assessments into decision-making for leukemia treatment with chemotherapy or BMT.

Dr. Sorror leads multicenter clinical trials that test supportive and palliative care, exercise programs and targeted management of medical conditions to improve BMT outcomes for vulnerable patients. Through both clinical and population-based studies, he develops and validates tools to predict survival, treatment side effects and quality of life. His work also explores patient experiences, values and treatment preferences to ensure therapies align with what matters most to them. Additionally, he is leading efforts to improve access to BMT and immunotherapy for patients from underrepresented groups or those facing socioeconomic barriers.

Throughout his career, Dr. Sorror has served as principal investigator on grants from the National Cancer Institute, National Heart, Lung and Blood Institute, American Cancer Society and Patient-Centered Outcomes Research Institute. He also holds several leadership positions with national and international organizations, such as the Bone Marrow Transplant Clinical Trials Network.

Area of Clinical Practice
Adult blood and marrow transplantation, cellular immunotherapy, blood cancers


“For older patients, the time remaining is extremely precious — and their focus is on those fine details of enjoying life, on the time they spend with a partner, with loved ones.”

— Dr. Sorror


Why do you practice oncology?

I grew up in Egypt, and when I was a child, my father was diagnosed with Hodgkin lymphoma and eventually died from it. At a young age, I learned about the important role of physicians in taking care of patients with cancer. I also recognized the limited access patients in Egypt had to research, supportive care and treatment options. Out of these experiences grew my desire to become an oncologist. Today, I treat patients the way I would treat my own family members. I use my research and clinical expertise to support survival and a good quality of life.

What motivates your research?

A majority of people with blood cancers like leukemia are seniors, but most studies about these diseases don’t include them. There’s a big gap in knowledge about how to provide care for people 60 and over, and we have to change that. My research tends to focus on traditionally marginalized patients — seniors or people who have multiple health challenges — so that we can figure out how to best help them. For example, I once cared for an 80-year-old man with cancer. At the time, only a few people in the world had ever undergone a bone marrow transplant at that age. But, using an evidence-based test I developed with colleagues at Fred Hutch, we discovered that he was actually a good candidate for the procedure. He got the transplant and was able to enjoy a few more precious years with his wife. That’s why I do this.


Current Projects

Assessment of novel biomarkers for prognostic evaluation of outcomes of stem cell transplantation or immunotherapy

Novel interventions to alleviate morbidity and mortality after allogeneic stem cell transplantation for older, frail or medically infirm patients with blood cancers

Pragmatic effectiveness trials to compare different treatment intensities and transplant options for AML in older patients or those with multiple chronic diseases

Enhancing access of underrepresented minorities and those with adverse social determinants of health to cellular therapies to cure blood cancers by exploring novel intervention approaches

Home-based care for patients with rare diseases treated with stem cell transplant or immunotherapy

Dietary and other interventions to improve outcomes of patients with body composition disorders or obesity treated with stem cell transplantation or immunotherapy for blood cancers

Focused exercise techniques for patients with newly diagnosed acute myeloid leukemia or with relapsed/refractory lymphoma or myeloma to better prepare them for stem cell transplantation or immunotherapy

Novel supportive and palliative care approaches to improve outcomes of stem cell transplantation or immunotherapy

Novel conditioning regimens for stem cell transplantation to enhance the outcomes of older patients with high risk acute myeloid leukemia

Clinical Trials

We make promising new treatments available to you through studies called clinical trials led by Fred Hutch physicians and researchers. Many of these trials at Fred Hutch have led to FDA-approved treatments and have improved standards of care globally. Together, you and your physician can decide if a study is right for you.

Publications

Many of our Fred Hutch physicians and researchers conduct ongoing research to improve standards of patient care. Their work is evaluated by other physicians and selected for publication to the United States National Library of Medicine, the largest medical library in the world.

Your Care Team

At Fred Hutch, you receive care from a team of providers with extensive experience in your disease. Your team includes physicians, a patient care coordinator, a registered nurse, an advanced practice provider and others, based on your needs. You also have access to experts like registered dietitians, social workers, acupuncturists, psychiatrists and more who specialize in supporting people with cancer or blood disorders. 

Insurance

Fred Hutch accepts most national private health insurance plans as well as Medicare. We also accept Medicaid for people from Washington, Alaska, Montana and Idaho. We are working to ensure that everyone, no matter what their financial situation, has access to the care they need.
