Acute Myeloid Leukemia
Diagnosis: The process of identifying a disease, condition or injury from it's signs and symptoms. A health history, physical exams and tests such as blood tests, imaging tests and biopsies, may be used to help make a diagnosis.
Treatment: A treatment is a medical intervention intended to remediate a health problem, such as a disease or disorder.
To comfirm a diagnosis of Acute Myeloid Leukemia, a small sample of your bone marrow will be taken to examine under a microscope. This procedure is known as a bone marrow biopsy.
The doctor or nurse will numb an area of skin at the back of your hip bone, before using a thin needle to remove a sample of liquid bone marrow.
Occasionally, they will remove some liquid bone marrow and a thin piece of bone marrow together.
You will not feel any pain during the procedure, but it can feel uncomfortable when the sample is being taken. You can have brusing and discomfort for a few days afterwards.
The bone marrow sample will be checked for cancerous cells. If cancerous cells are present, the biopsy can also be used to determine the type of leukemia you have.
This procedure takes 20 to 30 minutes.
Further Tests
Other tests can be used to get more information about the progress and extent of your AML. They can additionally help decide how it should be treated.
Blood Tests
Most people with AML have too many white blood cells and not enough red blood cells and not enough platelets. Sometimes the level of white blood cells can be too low. The presence of blast cells which are immature cells normally found in bone marrow but not circulating in the blood is another indicator of acute myeloid leukemia.
Genetic Testing
Genetic tests can be carried out on blood and bone marrow samples to find out what type of AML you have. This can help doctors make decisions about the most appropriate treatment.
Chest X-Ray
If you have AML, a chest x-ray can be used to check that your heart and lungs are healthy. These tests are important to also help doctors assess your general health before they decide on the most appropriate treatment.
Lumbar Puncture
In rare situations, where it is thought there is a risk that AML has spread to your nervous system, a lumbar puncture may be carried out. In this procedure, a needle is used to extract a sample of the fluid that surrounds and protects your spine (cerebrospinal fluid) so it can be checked for cancerous cells. If cancerous cells are found in your nervous system, it may affect your treatment.
If your healthcare provider determines you have AML, you may need further tests to determine the extent of the cancer and classify it into more of a specific AML subtype.
Your AML subtype is based on how your cells appear when examined under a microscope. Special laboratory testing may be used to identify the specific characteristics of your cells.
Your AML subtype helps determine which treatments may be best for you. Doctors are studying how different types of cancer treatment affect people with different AML subtypes.
Your doctor uses your AML subtype and other information to determine your prognosis and decide on your treatment options. Other types of cancer use numerical stages to indicate your prognosis and whether your cancer has spread, but there are no stages of Acute Myeloid Leukemia.
Instead, the seriousness of your condition is determined by:
- AML Subtype
- Your Age
- Your Overall Health
- Results from other tests and procedures, such as the number of white blood cells found in blood samples.
Treatment of Acute Myeloid Leukemia depends on several factors, including the subtype of the disease, your age, your overall health and your preferences.
In general, treatment falls into two phases:
Remission Induction Therapy
The purpose of the first phase of treatment is to kill the leukemia cells in your blood and bone marrow. However, remission induction usually does not wipe out all of the leukemia cells, so you need further treatment to prevent the disease from returning.
Consolidation Therapy
Consolidation Therapy (also called post-remission therapy or maintenance therapy) this phase of treatment is aimed at destroying the remaining leukemia cells. It is considered crucial to decreasing the risk of relapse.
Therapies used in these phases include:
Chemotherapy:
Chemotherapy is the major form of remission induction therapy, though it can be used for consolidation therapy. Chemotherapy uses chemicals to kill cancer cells in your body. People with AML generally stay in the hospital during chemotherapy treatments because the drugs destroy many normal blood cells in the process of killing leukemia cells. If the first cycle of chemotherapy does not cause remission it can be repeated.
Targeted Therapy:
Targeted drug treatments focus on specific abnormalities present within cancer cells. By blocking these abnormalities, targeted drug treatments can cause cancer cells to die. Your leukemia cells will be tested to see if targeted therapy may be helpful for you. Targeted therapy can be used alone or in combination with chemotherapy for induction therapy and consolidation therapy.
Bone Marrow Transplant:
A bone marrow transplant, also called a stem cells transplant, may be used for consolidation therapy. A bone marrow transplant helps reestablish healthy stem cells byreplacing unhealthy bone marrow with leukemia free stem cells will regenerate healthy bone marrow. Prior to a bone marrow transplant, you recieve very high doses of chemotherapy or radation therapy to destroy your leukemia producing bone marrow. Then you recieve infusions of stem cells from a compatible donor (allogenic transplant).
You can also recieve your own stem cells (autologous transplant) if you were previosuly in remission and had your healthy stem cells removed and stored for a future transplant.
Clinical Trials:
Some people with leukemia choose to enroll in clinical trials to try experimental treatments or new combinations of known therapies.
Alternative Medicine
No alternative treatments have been found helpful in treating acute myeloid leukemia. But some complementary and altervative treatments may relieve the symptoms you experience due to cancer or cancer treatment.
Alternative treatments that may help relieve symptoms include
- Acupuncture
- Exercise
- Massage
- Meditation
- Relaxation Activities, including yoga and tai chi
Make an appointment with your family doctor if you have signs and symptoms that worry you. If your doctor suspects you may have leukemia, you will likley be referred to a doctor who specializes in blood cell diseases (hematologist). Because appointments can be brief and because there is often a lot of information to discuss, it is a good idea to be prepared. Some information to help you get prepared and to know what to expect from your doctor.
Be aware of any pre-appointment restrictions: At the time youmake the appointment, be sure to ask if there is anything you need to do in advance, such as restrict your diet.
Write down any symptoms you are experiencing: This includes anything that may seem unrelated to the reason for which you scheduled the appointment.
Write down key personal information: This includes any major stresses or recent life changes.
Make a list of all medications: This can include any vitamins or supplements that you are taking.
Consider taking a family member or friend along: Sometimes it can be difficult to remember all the information provided during an appointment. Someone who accompanies you may remember something that you missed or forgot.
Write down questions to ask your doctor: Your time with your doctor is limited, so preparing a list of questions can help you make the most of your time together. List your questions from most important to least important in case time runs out. For Acute Myeloid Leukemia, some basic questions to ask may include:
- What is likely causing my symptoms or conditions?
- What are other possible causes for my symptoms or condition?
- What kinds of tests do I need?
- What is the best course of action?
- What are the alternatives to the primary approach that you are suggesting?
- I have these other health conditions, How can I best manage them together?
- Are there any restrictions that I need to follow?
- Should I seek a second opinion? What will that cost, and will my insurance cover it?
- Is there a genetic alternative to the medicine your prescribing?
- Are there brochures or other printed material that I can take with me? What websites do you recommend?
- What will determine whether I should plan for a follow-up visit?
Your doctor is likely to ask you a number of questions. Being ready to answer them may allow time later to cover other points you want to address. Your doctor may ask:
- When did you first begin experiencing symptoms?
- Have your symptoms been continuous or occasional?
- How severe are your symptoms?
- What, if anything seems to improve your symptoms?
- What, if anythign appears to worsen your symptoms?
