Symptoms
- Age. Myelofibrosis can affect anyone, but it's most often diagnosed in people older than 50.
- Another blood cell disorder. A small portion of people with myelofibrosis develop the condition as a complication of essential thrombocythemia or polycythemia vera.

Causes
The median survival of patients with myelofibrosis is 3.5-5.5 years and the 5 year survival is reduced to about half of expected for that appropriate age group and sex. Approximately <20% patients survive for 10 years. A simple scoring system uses two risk factors, which include hemoglobin (<10 g/dl) and leukocyte count (<4000/ul or >30,000/ul).
Prevention
The disease does not progress for a long period of time in some people. Survival estimates range depending on whether a person is in a low, intermediate, or high-risk group.

Transcript:Srdan Verstovsek, MD, PhD: Myelofibrosis is one of the myeloproliferative neoplasms, a chronic disease of the bone marrow. It is, unfortunately, the aggressive type. It does affect the life expectancy of the patients. The average survival is about 5 to 7 years.
Can you live 20 years with myelofibrosis?
Results from a retrospective study suggest that identification of patients with primary myelofibrosis likely to survive 20+ years can be made on the basis of age, sex, blood counts, and symptoms, without inclusion of genetic risk factors. This study was published in the American Journal of Hematology.
Does myelofibrosis always progress?
Myelofibrosis usually develops slowly. In its very early stages, many people don't experience signs or symptoms. As disruption of normal blood cell production increases, signs and symptoms may include: Feeling tired, weak or short of breath, usually because of anemia.

Definition. Myelofibrosis is a reactive and reversible process common to many malignant and benign bone marrow disorders.
Are there different stages of myelofibrosis?
Primary myelofibrosis stages Unlike other types of cancers, primary MF doesn't have clearly defined stages. Your doctor may instead use the Dynamic International Prognostic Scoring System (DIPSS) to categorize you into a low-, intermediate-, or high-risk group.
What happens if myelofibrosis is left untreated?
One of the biggest complications with myelofibrosis, especially if left untreated, is that patients can develop progressive abdominal distension and, as result of that, abdominal pain and early satiety. Once patients develop early satiety, they develop weight loss.

Your goal is to build up to one of these: About 150 minutes a week (roughly 20 minutes a day) of moderate exercise, like walking, swimming, or yoga. About 75 minutes a week of more vigorous exercise, like jogging, dancing, swimming, or riding your bike.
What causes myelofibrosis?
Causes. Myelofibrosis occurs when bone marrow stem cells develop changes (mutations) in their DNA. The stem cells have the ability to replicate and divide into the multiple specialized cells that make up your blood — red blood cells, white blood cells and platelets. It's not clear what causes the genetic mutations in bone marrow stem cells.
What type of cancer is associated with myelofibrosis?
Acute leukemia. Some people with myelofibrosis eventually develop acute myelogenous leukemia, a type of blood and bone marrow cancer that progresses rapidly.

As disruption of normal blood cell production increases, signs and symptoms may include: Feeling tired, weak or short of breath, usually because of anemia. Pain or fullness below your ribs on the left side, ...
What happens when a bone marrow cell is mutated?
It's not clear what causes the genetic mutations in bone marrow stem cells. As the mutated blood stem cells replicate and divide, they pass along the mutations to the new cells. As more and more of these mutated cells are created, they begin to have serious effects on blood production. The end result is usually a lack of red blood cells — which ...
What chemicals can cause myelofibrosis?
Exposure to certain chemicals. Myelofibrosis has been linked to exposure to industrial chemicals such as toluene and benzene. Exposure to radiation. People exposed to very high levels of radiation have an increased risk of myelofibrosis.
What are the most common mutations in myelofibrosis?
Several specific gene mutations have been identified in people with myelofibrosis. The most common is the Janus kinase 2 (JAK2) gene mutation. Other less common mutations include CALR and MPL. Some people with myelofibrosis don't have any identifiable gene mutations.
Can you get treatment for myelofibrosis right away?
Some people with myelofibrosis have no symptoms and might not need treatment right away. Others with more-serious forms of the disease might need aggressiv e treatments right away. Treatment for myelofibrosis, which focuses on relieving symptoms, can involve a variety of options.
How many people have myelofibrosis?
Myelofibrosis is a rare condition, with about 1.5 cases reported per 100,000 people each year in the United States. It occurs in both men and women. People of any age can have myelofibrosis, although it is more likely to be diagnosed in people over age 50.
What is myelofibrosis in cancer?
What is myelofibrosis? Myelofibrosis is a rare type of blood cancer in which the bone marrow (the soft, spongy tissue inside most bones) is replaced by fibrous scar tissue. It is considered a form of chronic leukemia.
What are the cells that are overproduced in myelofibrosis?
One characteristic of myelofibrosis is the overproduction of giant cells called megakaryocytes. Megakaryocytes normally release tiny fragments called platelets. Platelets play an important role in the formation of blood clots at the site of an injury.
What is the release of cytokines in myelofibrosis?
When myelofibrosis occurs, the bone marrow produces too many megakaryocytes, accompanied by the release of proteins called cytokines. Cytokines are the same substances that make you feel ill when you have the flu. The cytokines in myelofibrosis cause inflammation and buildup of more fibrous tissue in the bone marrow.
What is secondary myelofibrosis?
If it occurs as the result of a separate disease , it is known as secondary myelofibrosis (e.g. scar tissue in the bone marrow as a complication of an autoimmune disease). The bone marrow contains immature blood-forming cells that may develop into three types of specialized blood cells: red blood cells, white blood cells, or platelets.
Is myelofibrosis inherited?
Although myelofibrosis is not inherited, it is associated with DNA changes in certain genes. Proteins called janus-associated kinases (JAKs) play a role in myelofibrosis. JAKs regulate the production of blood cells in bone marrow by signaling the cells to divide and grow.
Does myelofibrosis show symptoms?
A person with myelofibrosis might not have any symptoms for many years. About one-third of patients do not show symptoms during the early stages of the disorder. However, during the course of the disease, they may experience the following symptoms or conditions:
How old do you have to be to get myelofibrosis?
Age has proven to be a deciding factor, most of the people affected seeming to be between 50 and 60 years old. If a person has already been diagnosed with another blood disorder, then complications can cause Myelofibrosis to form.
Can exposure to benzene cause myelofibrosis?
Disorders like essential thrombocythemia for example are often linked to the forming of Myelofibrosis. Certain things can be avoided however, like exposure to chemicals like toluene and benzene. Also shielding radiation contact can decrease the risk of gaining Myelofibrosis.
Can myelofibrosis cause leukemia?
The cancer is caused from genetic mutation through blood cells located in the body. This can later turn to a more severe leukemia if not treated.
Does ruxolitinib help with myelofibrosis?
If through blood tests a person is found to be in possession of the disorder, then medicines like ruxolitinib which target JAK2, the cell thought to be responsible for the mutation and blood production disruption, have been evaluated by the FDA and found to decrease several of the symptoms linked with Myelofibrosis.
Is myelofibrosis incurable?
However, this disease is incurable, meaning it will cause death eventually.

To understand this variable disease, which primarily strikes older people, here’s a look at how myelofibrosis affects your body over time.
What happens when your marrow isn't producing healthy cells?
When your marrow can’t produce healthy cells, your spleen or liver may start to produce blood cells instead.
Why does my bone marrow hurt?
The scarring in your bone marrow can inflame the tissue around the bone and make your bones and joints ache. You can also have joint pain from gout, caused by too much uric acid, which deposits sharp crystals in your joints. You may also have intense itching, run a low fever, or have night sweats.
Is myelofibrosis a form of leukemia?
Getty. Myelofibrosis (MF) is a rare form of leukemia, or cancer of the blood. In its early stages, many people have no signs of symptoms, but myelofibrosis is a serious disease that scars the bone marrow, which is where your blood forms, and disrupts the marrow’s ability to make healthy blood cells. The prognosis for someone with MF varies widely – ...
How to treat anemia with myelofibrosis?
Treatments for anemia. If myelofibrosis is causing severe anemia, you may consider treatment, such as: Blood transfusions. If you have severe anemia, periodic blood transfusions can increase your red blood cell count and ease anemia symptoms, such as fatigue and weakness. Sometimes, medications can help improve anemia.
What is the procedure to diagnose myelofibrosis?
This second procedure removes a small piece of bone tissue and the enclosed marrow. Tests and procedures used to diagnose myelofibrosis include: Physical exam. Your doctor will perform a physical exam. This includes a check of vital signs, such as pulse and blood pressure, ...
What is bone marrow transplant?
A bone marrow transplant, also called a stem cell transplant, is a procedure to replace your diseased bone marrow using healthy blood stem cells. For myelofibrosis, the procedure uses stem cells from a donor (allogeneic stem cell transplant).

For some, a bone marrow transplant may provide a chance for a cure, but this treatment is very hard on the body and it might not be an option for many people.
Is myelofibrosis a sign of anemia?
Blood tests. In myelofibrosis, a complete blood count typically shows abnormally low levels of red blood cells, a sign of anemia common in people with myelofibrosis. White blood cell and platelet counts are usually abnormal, too. Often, white blood cell levels are higher than normal, although in some people they may be normal or even lower than normal. Platelet counts may be higher or lower than normal.
