What is the treatment for CMML?
This may be treatments like blood transfusions and drugs called growth factors to help you feel good and have safe blood cell levels. This is called supportive care.
What is the first test for CMML?
Blood cell counts: This blood test is often the first test done. People with CMML have too many white blood cells called monocytes (mon-o-sites). They may have early (not mature) cells, called monoblasts, in their blood. (Monoblasts should only be in the bone marrow.)
How does chemo work?
Chemo is the short word for chemotherapy – the use of drugs to fight cancer. Most of the time chemo drugs are given into a vein or taken as pills. These drugs go into the blood and spread through the body. In CMML, chemo is may be used to control the number of CMML cells in the bone marrow so healthy cells can grow. Chemo is given in cycles or rounds. Each round of treatment is followed by a break. Treatment often lasts for many months.
What is CMML in medical terms?
What is chronic myelomonocytic leukemia (CMML)? Chronic myelomonocytic leukemia , or CMML for short, is a type of cancer that starts in cells in the bone marrow that are supposed to grow into different types of blood cells. (These cells are called monoblasts .)

Can CMML be staged?
This can help the doctor know how to treat the cancer and how likely it is that you'll get better. But CMML can't be staged by looking at the size of a tumor. It's split into 2 groups based on cell counts in the blood and bone marrow:
How to cure CMML?
The only way to cure CMML is to have a stem cell transplant from a matched donor. This is usually either a matched sibling or a matched unrelated donor. This is an intensive treatment and it has many risks. This is why it’s unfortunately not suitable for everyone.

What tests do doctors do for CMML?
a bone marrow test. Your doctor may also do tests on the bone marrow to look for changes in the chromosomes of the CMML cells. Chromosomes contain the genetic material inside cells.
Why do you need a platelet transfusion?
If your platelets are low you might require platelet transfusions, especially if you are experiencing any symptoms of bleeding. Having a lot of blood transfusions can cause a build up of iron in your body. Red blood cells contain iron and your body stores this.
How does chemo work for CMML?
Chemotherapy for CMML. Chemotherapy uses cell killing (cytotoxic) drugs to destroy the abnormal cells. The drugs work by disrupting the growth of cells and stopping them from dividing. You can have chemotherapy as a tablet, an injection just under your skin, or as an injection into a vein.

What is CMML in medical terms?
Chronic myelomonocytic leukemia (CMML) is a clonal hematopoietic malignancy that may deserve specific management. Defined by a persistent peripheral blood monocytosis ≥1 × 10 9 /L and monocytes accounting for ≥10% of the white blood cells, this aging-associated disease combines cell proliferation as a consequence of myeloid progenitor hypersensitivity to granulocyte-macrophage colony-stimulating factor with myeloid cell dysplasia and ineffective hematopoiesis. The only curative option for CMML remains allogeneic stem cell transplantation. When transplantation is excluded, CMML is stratified into myelodysplastic (white blood cell count <13 × 10 9 /L) and proliferative (white blood cell count ≥13 × 10 9 /L) CMML. In the absence of poor prognostic factors, the management of myelodysplastic CMML is largely inspired from myelodysplastic syndromes, relying on erythropoiesis-stimulating agents to cope with anemia, and careful monitoring and supportive care, whereas the management of proliferative CMML usually relies on cytoreductive agents such as hydroxyurea, although ongoing studies will help delineate the role of hypomethylating agents in this patient population. In the presence of excessive blasts and other poor prognostic factors, hypomethylating agents are the preferred option, even though their impact on leukemic transformation and survival has not been proved. The therapeutic choice is illustrated by 4 clinical situations among the most commonly seen. Although current therapeutic options can improve patient’s quality of life, they barely modify disease evolution. Improved understanding of CMML pathophysiology will hopefully lead to the exploration of novel targets that potentially would be curative.
What is the hemoglobin level in CMML?
At CMML diagnosis, the hemoglobin level is <100 g/L in ∼40% of patients, with 25% having red cell transfusion requirements. Anemia impairs overall survival and is incorporated in diverse scoring systems. 8, 11 Clinical experience and individual cases suggested that ESAs provided comparable results in MD-CMML and MDS. 37, 38 A recent retrospective analysis of their efficacy demonstrated that a response was observed in ∼60% of patients and red cell transfusion independence in ∼30%. A better response was detected in anemic patients with low endogenous serum erythropoietin level and transfusion independence. 39 Thrombocytopenia is common in CMML patients because of megakaryocyte dysplasia 40, 41 or autoimmune mechanisms. 42-44 The orally bioavailable, small nonpeptide thrombopoietin receptor agonist eltrombopag demonstrates some efficacy. Because safety concerns have been raised, 45 this drug should be used only in clinical trials ( Table 3 ).
What are IWG response criteria for MDS?
IWG response criteria for MDS are not completely suited for adult patients with MDS/MPN 106 (eg, they do not capture the treatment effects on the proliferative component). Also, scales that have not been specifically developed for CMML barely reflect the drug effects on constitutional symptoms. 90 An international consortium recently proposed specific end points to better measure benefit to the patient. 21 The proposed criteria may capture meaningful improvements not seen with IWG criteria, but the more stringent definition of complete response leads to divergent response rates compared with IWG criteria. 117
What are the symptoms of MPN-CMML?
102-104 Nevertheless, splenomegaly is a poor prognostic factor in CMML treated with HMAs. 105
What is the first line of treatment for inflammatory and immune diseases?
First-line treatment of inflammatory and immune diseases consists mostly of steroids, with ∼85% response. Steroid dependence and recurrence are observed in ∼50% of cases. Most additional immunosuppressive therapies may increase the risk of severe cytopenia and infections.
Is there a treatment for CMML?
Except for allogeneic stem cell transplantation (ASCT), there is no disease-modifying treatment in CMML. Current therapies aim to improve symptom burden using a personalized strategy guided by cytopenia-induced or proliferation-associated symptoms. Commonly used drugs include erythropoiesis-stimulating agents (ESAs) in anemic patients, cytoreductive drugs in proliferative diseases, and hypomethylating agents (HMAs) in the most severe CMML, especially when cytopenias predominate ( Figure 3 ). The therapeutic choice is illustrated by 4 common clinical situations.
Is ASCT curative therapy?
ASCT remains the unique potentially curative therapy and the preferred therapeutic option in younger patients with high-risk CMML. It is therefore essential to assess the disease risk at diagnosis, using WHO criteria and 1 of the currently established scoring systems. A minority of high-risk patients is eligible, owing to advanced age and comorbidities. The advent of reduced intensity conditioning and alternate donor sources may increase the number of transplanted patients. All of the studies so far have been retrospective. Except a few recent reports, 70, 71 most have included a small number of patients. 72-77 Current recommendations are therefore based on expert opinion rather than evidence. 78, 79 The median age of transplanted patients ranges from 50 to 56 years. About one-third of these patients are alive a few years later. Deaths are due almost equally to treatment-related mortality or posttransplant disease relapse. Indirect evidence for a graft-versus-CMML effect comes from correlations between graft-versus-host disease and reduction in relapse. 71 The main risk factor for transplant-related mortality is the disease status. Although there is no consensus about the correct timing of ASCT in CMML patients, transplantation should preferably be performed early after diagnosis and after establishing the best possible remission status. 70 There is no evidence whether the use of cytoreductive therapy before transplant could improve the outcome compared with frontline ASCT. Expert opinion suggests treatment before transplantation, especially when marrow blast cells are >10% and in patients with high-risk CMML according to available scoring systems. 78, 79 The best treatment of reducing tumor burden before transplantation, either intensive chemotherapy or HMAs, remains a controversial issue. 80, 81 Many experts currently consider pretreatment with an HMA in the case of CMML-2, even though evidence from prospective clinical trials is lacking. Some transplant candidates are eventually not transplanted owing to pretreatment toxicity or disease progression before transplant.
What is the best treatment for CMML?
Radiation therapy with high-energy rays or particles to destroy cancer cells. Stem cell transplant, which replaces blood-forming stem cells in your bone marrow with healthy stem cells from a donor. Clinical trials, also called research studies may offer good treatment options for some people with CMML.
Where does CMML start?
Chronic myelomonocytic leukemia (CMML) starts in the bone marrow and then moves to the blood. It happens when monocytes in the bone marrow begin to grow out of control, filling the bone marrow and preventing other blood cells from growing.
What is the most common symptom of CMML?
What are the symptoms of CMML? The most common sign of chronic myelomonocytic leukemia (CMML) is having too many monocytes, a type of white blood cell, in the blood. These cells can settle in the liver and spleen, causing them to enlarge.
What are the risk factors for CMML?
They include: Older age (60 or older) Being male. Being exposed to certain chemicals at work or in the environment. Being exposed to radiation. Past treatment with certain anticancer drugs.
How to treat cancer cells?
Treatment options include: Supportive care with blood transfusions, growth factors and antibiotics to treat symptoms by increasing blood counts and stopping infections. Chemotherapy to kill cells cancer cells using cytotoxic agents. Radiation therapy with high-energy rays or particles to destroy cancer cells.
Is CMML rare in young people?
CM ML occurs more often in men than in women and is very rare in young people. CMML used to be considered a type of myelodysplastic syndrome (MDS) because patients have abnormal-looking (dysplastic) cells in their bone marrow. But other factors associated with CMML didn't match the definition of MDS.
Is CMML a myelodysplastic disease?
Instead, they more closely resembled myeloproliferative neoplasms, a group of diseases where the bone marrow makes too many cells. Since CMML has features of both myelodysplastic syndrome and myeloproliferative neoplasm, experts created a new “overlap” category of myelodysplastic/myeloproliferative neoplasm.
What is the best treatment for iron overload?
This iron build up is usually seen only in people who receive many transfusions over a period of years. Drugs called chelating agents can be used to treat and prevent iron overload from transfusions. Chelating agents are substances that bind with iron so that the body can get rid of it.
Can CMML be spread by blood transfusion?
Some people are concerned about a slight risk of infection (hepatitis or HIV) spread by blood transfusion. This possibility is very unlikely, and the benefits of the transfused cells greatly outweigh this risk . People with CMML often need a lot of blood transfusions. This can cause excess iron to build up in the body.
Can CMML patients get platelets?
CMML patients with bleeding problems caused by a shortage of platelets may benefit from platelet transfusions. People with CMML tend to get infections very easily. They should be especially careful to avoid cuts and scrapes and care for any injury right away.
Is CMML hard to treat?
Chronic myelomonocytic leukemia (CMML) can be hard to treat. For many people with CMML, the main goal is to prevent the problems caused by low blood cell counts. For instance, low red blood cell counts (anemia) can cause severe fatigue.
What is CMML in EHA?
First CMML guidelines produced by EHA, now available. Chronic myelomonocytic leukemia (CMML) is a rare disease with overlapping features of two categories of bone marrow and blood cell disorders that poses challenges in clinical management.
Can CMML be treated?
For some patients with favorable prognostic factors, "watchful waiting" (observation without treatment) may be appropriate. Available treatment options may lead to longer survival, but currently can't cure CMML.
Is stem cell transplantation the only treatment for CMML?
Stem cell transplantation remains the only curative therapy for CMML. However, this isn't an option for every patient and survival rates are relatively low. The experts emphasize the need for new transplantation strategies, including approaches to prevent relapse after transplantation.
