The Malignant Hematology team in the Division of Hematology/Oncology at The University of Texas Health Science Center at Houston (UTHealth) provides comprehensive, patient-centered care for patients diagnosed with cancers of the blood.


The Malignant Hematology team’s mission is to:

  • Provide high-quality, personalized medical care to patients diagnosed with, suspected of having, or at high risk for leukemia, lymphoma, or multiple myeloma in a well-coordinated, multidisciplinary fashion so as to improve, enhance, and sustain quality of life
  • Educate current and future health care providers and general practitioners on various aspects of blood cancers
  • Contribute to advances in biomedical research in the areas of prevention, screening, and treatment of hematologic malignancies
  • Promote good health in our community through collaborations with physicians and local leaders and patient advocacy groups

Services Offered

Our team of highly skilled physicians and allied healthcare professionals provides consultation and management in both the outpatient and inpatient setting at Memorial Hermann TMC.

We provide comprehensive care through collaboration with members of the Divisions of Surgery, Radiation Oncology, Pathology, and Radiology and includes multidisciplinary tumor board conferences and coordination of care through the Memorial Hermann Cancer Center for the treatment of Acute and Chronic Leukemias, Malignant Lymphomas, and Plasma Cell Disorders (Multiple Myeloma, MGUS and Amyloid-related Disorders).

These services include genetic counseling, infusion services, palliative care, and social work. Home care and follow ups visits are coordinated by a team of expert nurse navigators.

Acute Leukemia

The program for the management and treatment of acute leukemia is unique at McGovern Medical School and the Memorial Hermann System. It provides easy access for patients with acute leukemia either by direct referral or hospital-to-hospital transference from other institutions.

A unique feature of this program is the designation of a permanent regular bed for the Leukemia Program in the chemotherapy unit. This allows the seamless transfer of cases to the leukemia floor and prompt initiation of therapy.

We are committed to be a resource to the patients with acute leukemia in the Memorial Hermann System and in the greater Houston area.

Our comprehensive array of programs allows us to be of service to patients with acute leukemia with specific clinical situations such as those with acute leukemia during pregnancy as well as patients with complex cardiovascular conditions.

Physicians needing to transfer a patient for urgent care may contact the Memorial Hermann System Transference Center at 713-704-2500.
