What is leukemia?

Leukemia is a disorder involving blood cells. Healthy cells form in the bone marrow and mature into red blood cells (to deliver oxygen and nutrients to the body’s tissues), white blood cells (to fight infections) and platelets (to stop bleeding).

In patients with leukemia, these cells do not mature as they should or they transform into irregular blood cells that do not function normally. As abnormal cells build up in the bone marrow and bloodstream, the patient may experience anemia, susceptibility to infections and bleeding that does not clot due to the lack of functional red blood cells, white blood cells and/or platelets.

On a general scale, leukemia is classified by the types of cells affected (myeloid or lymphoid) and whether it is fast- or slow-growing (acute or chronic). As such, the four major subtypes of leukemia are:


What risk factors are linked to leukemia?

Factors that can elevate risk of leukemia include:

  • A personal or family history of leukemia or blood disorders
  • Prior treatment with radiation or chemotherapy
  • Exposure to radiation or certain chemicals, including benzene, formaldehyde and Agent Orange
  • Infections with specific viruses, such as the Epstein-Barr virus or human T cell lymphoma/leukemia virus (HTLV-1)
  • Being male
  • Smoking


What are the symptoms of leukemia?

Common symptoms associated with leukemia include:

  • Unexpected loss of weight or appetite
  • Fatigue
  • Anemia
  • Frequent or long-lasting infections
  • Excessive bleeding and bruises, or bleeding that does not stop
  • Enlarged spleen or lymph nodes
  • Petechiae (flat, round and red pinpoint spots under the skin)
  • Shortness of breath
  • Fevers, chills and other flu-like symptoms
  • Night sweats


Although these symptoms can be caused by other conditions, you should check with a doctor – preferably a hematologist – to get a definitive diagnosis.

Diagnosing leukemia

An accurate diagnosis is crucial to optimal treatment planning and outcomes. This is especially important for leukemia because this disease has numerous subtypes and factors that can determine specific courses of treatment.

At City of Hope, our team of experts can precisely diagnose leukemia, classify its subtype, identify its severity and find the best treatments to fight the disease.

How is leukemia detected?

Once you notice symptoms, or as part of a routine examination, your doctor may use the following tests to look for leukemia:

  • Physical exam
  • Blood tests
    • Complete blood count: This test checks for the number of red blood cells, white blood cells and platelets in your blood sample.
    • Peripheral blood smear: Also known as a blood film, this test smears a thin layer of blood on a glass slide for examination under a microscope.
  • Bone marrow aspiration and biopsy: A hollow needle is inserted into your hipbone or breastbone to extract a sample of bone marrow, blood and bone tissue. A pathologist then examines the tissue for signs of cancer.
  • Imaging tests: Although medical imaging procedures – such as X-ray and magnetic resonance imaging scans – are not typically used to diagnose leukemia, they may be ordered if your doctor suspects that leukemia cells are growing in an organ, such as the spleen or liver.

If cancer is found, additional tests are performed to determine the type and stage of disease. These tests include:

  • Cytogenetic analysis: A test that looks for genetic or chromosomal abnormalities in a blood or bone marrow sample
  • Immunophenotyping: This test looks for specific markers on the surface of the leukemia cells, and is used to help identify the disease subtype.
  • Reverse transcription-polymerase chain reaction (RT-PCR) test: This test uses chemicals to look at structure or function of genes, and can help identify leukemia subtypes.
  • Lumbar puncture (spinal tap): If your doctor suspects that leukemia cells have spread to your brain and spinal cord, a small sample of your cerebrospinal fluid – or CSF – may be extracted from your spine for further evaluation.


What are the current screening guidelines for leukemia?

There are currently no screening guidelines for leukemia, since no screenings have been shown to lower risk of dying from leukemia for people of average risk. However, your physician may recommend more vigorous monitoring if you are at a high risk of developing this disease, due to:

  • Personal/family history
  • Specific inherited conditions
  • Prior chemical or radiation exposure
  • Chemotherapy and radiation therapy to treat another cancer

Leukemia treatment options

We offer not just the best known therapies, but also the best therapy for a particular person. Joseph Alvarnas, M.D., associate clinical professor, Department of Hematology & Hematopoietic Cell Transplantation

Your cancer is every bit as unique as you are, and that is why treatment at City of Hope is focused around you and your loved ones.

This means our physicians will personally consult with you about your disease, treatment options and desired outcomes. We will also analyze your specific cancer for genetic and molecular markers that can guide us to more effective therapies. Afterward, our multidisciplinary team will work together to discuss, design and deliver an individual treatment plan to best meet those goals.

The innovative treatments we use to treat leukemia include drug therapy, radiation therapy and bone marrow/stem cell transplantation.

Drug Therapy

Drug therapy may be given to patients to fight leukemia cells throughout the body by killing them or stopping their growth and spread. These drugs include:

  • Chemotherapy, which targets rapidly dividing cells, including leukemia cells
  • Targeted therapy, which selectively identifies and attacks leukemia based on specific markers expressed by the cancerous cells
  • Immunotherapy, which stimulates the patient’s own immune system to attack leukemia cells

Drugs may also be prescribed to treat conditions related to leukemia or its treatments, such as low blood cell counts, nausea or pain.

The drug or drug combination used depends on the leukemia subtype, disease prognosis, previous treatments used, the patient’s health and overall treatment goals. This personalized medicine approach also evaluates the leukemia cells’ molecular and genetic makeup, which can help identify treatments that are more effective and with fewer side effects.

City of Hope has a wide portfolio of cancer-fighting drugs available in its on-site pharmacy, allowing our medical oncologists to plan and prescribe a drug regimen that can best fight leukemia while minimizing side effects.

In addition to standard drug treatments, patients may also be eligible for new, promising drugs through our clinical trials program.



Radiation Therapy

Radiation therapy uses focused, high-energy X-rays or other forms of radiation to kill cancer cells.

For leukemia, radiation is typically used in the following manner:

  • To treat leukemia cells that have accumulated in specific areas of the body, such as the brain or the spleen
  • Before a stem cell transplant to help kill leukemia cells throughout the bone marrow and body
  • To treat symptoms caused by leukemia, such as bone pain


City of Hope is a leader in the use of radiation to treat cancers. Our advanced technologies and experienced staff can plan and deliver radiation precisely to the bone marrow, where leukemia originates, while sparing nearby organs and tissues. This results in fewer radiation-associated side effects while maintaining excellent clinical outcomes.



Bone Marrow / Stem Cell Transplantation

Stem cell transplantation allows doctors to deliver greater doses of radiation and drugs to fight leukemia. After the high-intensity treatments, patients are infused with blood stem cells that will grow and mature in the bone marrow, restoring their blood-forming functions.

Stem cell transplants may also fight cancer through its graft-versus-tumor effect, where the newly transplanted stem cells produce an immune reaction against remaining leukemia cells throughout the body.

The stem cells may come from another donor (allogeneic transplant) or the patient’s own cells (autologous transplant).

City of Hope is one of the world’s largest and most successful bone marrow and stem cell transplant centers. Our Hematologic Malignancies and Stem Cell Transplantation Institute is a leader in setting standards for this lifesaving procedure, improving outcomes for leukemia patients of all ages.

Highlights of our transplant program include:

  • Recognition as an “overperforming” transplant center for 11 consecutive years by The Center for International Blood and Marrow Transplant Research Center
  • One of the first and most experienced centers to use nonmyeloablative (mini) transplants, which allow a greater range of patients (particularly those too weak to tolerate a standard transplant) to be treated with this lifesaving therapy
  • Integration of transplant and nontransplant therapies, so there is a smoother transition of treatments for leukemia patients who will eventually need a stem cell transplant
  • Pioneer in the use the nonmyeloablative (“mini”) transplant that allows older or weaker patients to benefit from this lifesaving therapy
  • Experience in treating a wide range of leukemia cases, including advanced disease and higher risk patients
  • A long-term, follow-up program that monitors for late effects and provide timely interventions




Active Surveillance

For slower-growing, less aggressive leukemias, active surveillance — also known as watchful waiting — is a viable treatment option. This method involves closely monitoring a patient with regular checkups and blood work, and beginning therapy when the disease begins to show signs of progression. Active surveillance allow doctors to deliver treatment when it is the most effective, sparing patients from unnecessary therapies and side effects.

City of Hope’s renowned physicians and researchers in the Hematologic Malignancies and Stem Cell Transplantation Institute utilize the latest in technology and innovation to treat leukemia, coupled with our enduring belief in providing unparalleled compassionate care. or contact us at 800-826-HOPE.

Leukemia research and clinical trials

At City of Hope, leukemia clinicians and researchers collaborate extensively to develop and evaluate new therapies for better survival and quality-of-life outcomes. Our patients have access to a wide variety of clinical trials including new chemotherapy and targeted therapies, hormone therapies with fewer side effects, novel surgical techniques, innovative radiation approaches and new prevention strategies.

These trials give current patients access to promising, leading-edge therapies and improve overall care for future patients worldwide. Visit our clinical trials page to learn more about current studies and their eligibility criteria.

Some of our current research projects include:

  • CAR-T cell therapy: Immune system cells called T cells guard against disease; they can detect invaders such as bacteria and viruses and destroy them. City of Hope scientists are currently investigating to see how these cells can be reprogrammed to recognize and attack leukemia, as well.
  • Enhanced subtype profiling: While leukemia is typically classified as one of four major groups, it is actually a collection of over a hundred abnormalities that lead to uncontrolled cell growth. Our researchers are actively studying these subtypes and whether they have specific genetic or molecular targets to focus therapy on.
  • New therapies for relapsed/refractory disease for patients who have undergone and failed standard treatments. These clinical trials may include novel agents developed at City of Hope, or new combinations or regimens of already-approved therapies that may be more effective.
  • Developing more tolerable regimens for patients who cannot withstand standard treatments, such as older patients and those with comorbid conditions.
  • Investigating "leukemia stem cells" that allow the disease to relapse and grow following cancer treatment. By better understanding the biology and weaknesses of these cancer stem cells, scientists and clinicians can develop better treatments that produce lasting cures.
  • Enhance bone marrow/stem cell transplants: While stem cell transplants can be a lifesaving procedure for leukemia patients, they also carry a risk of graft-versus-host disease (GvHD), in which the newly transplanted stem cells do not recognize the recipient’s body as their own and start producing an immune response against it, leading to chronic and potentially serious complications. To reduce the likelihood of GvHD and to improve transplant outcomes, City of Hope is researching new ways to classify and match stem cell donors and recipients.
  • Improving survivorship: City of Hope runs an ongoing long-term, follow-up program for bone marrow transplant recipients, which monitors them for chronic side effects and educates them on improving their quality of life based on their disease and the treatments they have received.
