What Is Essential Thrombocythemia (ET)?

Essential thrombocythemia is a chronic form of leukemia where patients' bone marrow makes too many platelets. The excess platelets increase the risk of blood clots which can lead to strokes and heart attacks. The disease most commonly affects people over age 50, but also affects children in rare cases.

Information about childhood leukemia can be found at the Lucile Packard Children's Hospital, which has excellent programs and doctors.

Clinical Trials

Clinical trials are research studies that evaluate a new medical approach, device, drug, or other treatment. As a Stanford Health Care patient, you may have access to the latest, advanced clinical trials.

Open trials refer to studies currently accepting participants. Closed trials are not currently enrolling, but may open in the future.

Before beginning treatment, ask your doctor about any clinical trials you should consider. Learn more about clinical trials for cancer patients.
