    Richard F. Ambinder, M.D., Ph.D., currently serves as the James B. Murphy Professor of Oncology and the Director of the Division of Hematologic Malignancies at the Johns Hopkins Kimmel Cancer Center. He is program co-leader of the Hematologic Malignancies and Bone Marrow Transplantation Program and leads the AIDS Malignancy Consortium (AMC) site at Johns Hopkins and the AMC Translational Sciences Working Group nationally. Dr. Ambinder graduated from Harvard College with a Bachelor’s degree in biochemistry, after which he received his medical degree from the Johns Hopkins University School of Medicine before completing his residency at the Johns Hopkins Hospital. He also earned his Ph.D. in pharmacology from the Johns Hopkins University, and completed his oncology fellowship at Johns Hopkins. Within the clinic, Dr. Ambinder is active in the treatment of lymphoma and Kaposi’s sarcoma. Dr. Ambinder’s research is focused on exploring opportunities to prevent or treat cancer with viral infections. Virus-associated tumors are among the most common malignancies in certain populations and regions. For instance, Burkitt's lymphoma (EBV) and Kaposi's sarcoma (KSHV) are common in equatorial Africa, nasopharyngeal carcinoma (EBV) is common in southern Chinese populations or those with southern Chinese origins, and immunoblastic lymphomas (EBV) are common in immunocompromised patients (organ transplant recipients, AIDS patients, etc). Thus, Dr. Ambinder’s new approaches to prevention, diagnosis, and treatment stand to have a direct impact on the lives of cancer patients around the globe. Additionally, the study of how viruses can impact these tumors is important in creating model systems for the development of new approaches to cancer care. Currently, many immunotherapies target unidentified antigens, making the measurement of relevant immune responses problematic at best. However, in EBV-associated tumors the antigens are well defined, thus allowing the Ambinder lab to define the epitope-specific cellular immune responses. As a result of this breakthrough, interventions designed to alter immune response —whether they be vaccine based interventions, adoptive immunotherapy interventions, or pharmacologic interventions — may all be assessed in terms of relevant surrogate markers. Much in the same way the treatment of Hodgkin's lymphoma with radiotherapy and chemotherapy paved the way for the modern approach to cancer treatment more broadly, the treatment of EBV-associated tumors (including Hodgkin's lymphoma) may pave the way to the more generalized use of these modalities to treat a myriad of cancer types. Dr. Ambinder is rated as an Advanced provider by MediFind in the treatment of Chronic B-Cell Leukemia (CBCL). His top areas of expertise are Hodgkin Lymphoma, Non-Hodgkin Lymphoma, B-Cell Lymphoma, Tissue Biopsy, and Bone Marrow Aspiration.

    What is the definition of Chronic B-Cell Leukemia (CBCL)?

    Chronic B cell leukemia is a type of chronic lymphocytic leukemia (CLL), or cancer of the blood and bone marrow that mainly affects adults. In chronic B cell leukemia, the bone marrow produces too many B lymphocytes, which are white blood cells that fight infection. Chronic B cell leukemia represents 95% of all chronic lymphocytic leukemias.

    When should I see a Chronic B-Cell Leukemia (CBCL) doctor in Maryland, US?

    There are various reasons why you may want to see a specialist, such as: 

    • Your primary care provider recommends it. 
    • Your condition requires expert knowledge and specialized care. 
    • Your symptoms persist or worsen despite treatment. 
    • You need specialized testing or procedures. 
    • You want a second opinion.  

    What should I consider when choosing a Chronic B-Cell Leukemia (CBCL) doctor in Maryland, US?

    It’s important to see a provider with expertise in your specific condition. Each provider profile in MediFind’s doctor database includes information on which conditions they treat, years of experience, research contributions, languages spoken, insurance plans accepted, and more.  

    How does MediFind rank Chronic B-Cell Leukemia (CBCL) doctors in Maryland, US?

    MediFind’s rankings are based on a variety of data sources, such as the number of articles a doctor has published in medical journals, participation in clinical trials and industry conferences, as well as the number of patients that provider sees for a given condition. Note that MediFind’s provider database is not based on user reviews, and providers do not pay to be included in the database. 

    What types of insurance are accepted by Chronic B-Cell Leukemia (CBCL) doctors in Maryland, US?

    Most profiles in MediFind’s doctor database include a list of insurance plans accepted by that provider. However, it’s a good idea to contact the provider’s office to make sure they still accept your insurance, then doublecheck by contacting your insurance plan to confirm they’re in network. 

    How can I book an appointment online with a Chronic B-Cell Leukemia (CBCL) doctor in Maryland, US?

    MediFind offers direct scheduling for certain providers using the “Request Appointment” button on that provider’s profile. If the schedule option is not available for a provider, tap the red “Show Phone Number” button on their profile to get their contact information. If you prefer to find providers who offer online scheduling, select “Schedules online” under the “Availability” category of the filter feature on the left side of the Chronic B-Cell Leukemia (CBCL) doctor search results page. 

    Why is it important to get a second opinion from a different Chronic B-Cell Leukemia (CBCL) doctor?

    Second opinions are an opportunity to confirm a diagnosis and its root cause, learn about alternative treatment options, or simply gain peace of mind. Many people, especially those with serious diagnoses, get second opinions so they can understand all their options and make informed decisions, so don’t hesitate to get one if you have any doubts or need more information or clarification regarding your care. Note that some insurance plans require second opinions, while others don’t cover second opinions, so be sure to confirm with your insurance provider first.   

    How can I prepare for my appointment with a Chronic B-Cell Leukemia (CBCL) doctor in Maryland, US?

    Prepare for your appointment by gathering the following items: 

    • Copies of medical records (dating back at least one year) 
    • Your medical history, including illnesses, medical conditions, surgeries, and other doctors you see 
    • Family history of disease 
    • List of current prescription drugs, over-the-counter medicines, vitamins, and herbal remedies or supplements including names and doses 
    • Allergies to medications, food, latex, insects, etc.  
    • List of questions and concerns 
    • Your insurance card 

    You might also contact the provider’s office to see if they offer transportation or childcare services or if you’re allowed to bring a loved one for support or to take notes during your visit. 

    What questions should I ask my Chronic B-Cell Leukemia (CBCL) doctor?

    Here are some sample questions: 

    • Can you explain in simple terms what this condition is and how it’s treated? 
    • What symptoms or side effects should I watch for? 
    • What tests will be involved, and when can I expect results? 
    • Are there other specialists I need to see? 
    • What’s the best way to reach you if I have follow-up questions? 

    How can I learn about the latest clinical trials and research advances my Chronic B-Cell Leukemia (CBCL) doctor may know about?

    MediFind’s Clinical Trials tool asks you a series of questions to help you narrow down your search by health condition, age, gender, location, how far you’re willing to travel, and more. Each question you answer filters down the number of trials until you find the ones that are most relevant to you. 

    MediFind’s Latest Advances tool features summaries of recent articles published in medical journals. We use cutting-edge technology to scour medical publication databases for the latest research advancements on any given condition, then we simplify this information in a way that’s useful and easy to understand.
