Efrat Luttwak, MD, MPH
We post reviews for MSK healthcare providers who have at least 30 patient experience surveys completed. If you do not see reviews for a provider, it may be because they do not yet have enough survey responses, or the provider may not be part of the group of healthcare providers included in the survey.
Only outpatient providers are included in the survey. Healthcare providers who only work in the hospital or in urgent care are not included in the survey. Pathologists or researchers who do not provide direct care to patients do not have reviews.

Get to Know Me
I’m a hematologist-oncologist who specializes in the care of people diagnosed with lymphoma, a type of cancer that starts in blood cells called lymphocytes. I see patients at Memorial Hospital and the David H. Koch Center for Cancer Care at Memorial Sloan Kettering Cancer Center (MSK) in Manhattan, and MSK Commack on Long Island.
My career began with a dual degree in medicine and a master’s in public health from the Jerusalem Hebrew University in 2012. Since then, I have been engaged in both clinical practice and research, with a special focus on lymphoma. From my residency and fellowship at Tel Aviv-Sourasky Medical Center in Israel, to an advanced fellowship at MSK, I have gained invaluable experience and expertise.
I focus on providing comprehensive care for people with various types of lymphoma, including Diffuse large B cell lymphoma, follicular, marginal and mantle cell lymphoma. I believe in a patient-centered approach that blends the latest research with compassionate care. A cancer diagnosis can cause anxiety and uncertainty, and I strive to support my patients and their families at every step of the way. My goal is to develop treatment plans that are effective and tailored to each person’s unique needs and circumstances.
My research is driven by a passion for advancing lymphoma care and improving patient outcomes. I am dedicated to exploring innovative treatments for lymphomas and understanding the biology of these diseases. My work has included studying the biology of follicular lymphoma transformation, aiming to predict and eventually prevent it, as well as investigating resistance mechanisms in CAR T cell therapy.
Outside of the office, I enjoy spending time with my family, running, hiking, and reading. I look forward to meeting you and working together to achieve the best possible outcomes for your health and well-being.
I'm a lymphoma specialist, which is a doctor with special training in diagnosing and treating lymphoma (lim-FOH-muh). This cancer starts in the cells of the immune system.

Disclosures
Members of the MSK Community often work with pharmaceutical, device, biotechnology, and life sciences companies, and other organizations outside of MSK, to find safe and effective cancer treatments, to improve patient care, and to educate the health care community. These activities outside of MSK further our mission, provide productive collaborations, and promote the practical application of scientific discoveries.
MSK requires doctors, faculty members, and leaders to report (“disclose”) the relationships and financial interests they have with external entities. As a commitment to transparency with our community, we make that information available to the public. Not all disclosed interests and relationships present conflicts of interest. MSK reviews all disclosed interests and relationships to assess whether a conflict of interest exists and whether formal COI management is needed.
