Many different anti-cancer drugs are effective for the treatment of AML. Treatments vary somewhat according to the age of the patient and according to the specific subtype of AML. Overall, the strategy is to control bone marrow and systemic (whole-body) disease, while offering specific treatment for the central nervous system (CNS), if involved.

In general, most oncologists rely on combinations of drugs for the initial, "induction phase" of chemotherapy. Such combination chemotherapy usually offers the benefits of early remission and a lower risk of disease resistance. "Consolidation" and "maintenance" treatments are intended to prevent disease recurrence. Consolidation treatment often entails a repetition of induction chemotherapy or the intensification chemotherapy with additional drugs. By contrast, maintenance treatment involves drug doses that are lower than those administered during the induction phase.

For most people with CLL, it is incurable by present treatments, so treatment is directed towards suppressing the disease for many years, rather than totally and permanently eliminating it. The primary chemotherapeutic plan is combination chemotherapy with chlorambucil or cyclophosphamide, plus a corticosteroid such as prednisone or prednisolone. The use of a corticosteroid has the additional benefit of suppressing some related autoimmune diseases, such as immunohemolytic anemia or immune-mediated thrombocytopenia. In resistant cases, single-agent treatments with nucleoside drugs such as fludarabine, pentostatin, or cladribine may be successful. Younger and healthier patients may choose allogeneic or autologous bone marrow transplantation in the hope of a permanent cure.

To overcome imatinib resistance and to increase responsiveness to TK inhibitors, four novel agents were later developed. The first, dasatinib, blocks several further oncogenic proteins, in addition to more potent inhibition of the BCR-ABL protein, and was initially approved in 2007 by the US FDA to treat CML in patients who were either resistant to or intolerant of imatinib. A second new TK inhibitor, nilotinib, was also approved by the FDA for the same indication. In 2010, nilotinib and dasatinib were also approved for first-line therapy, making three drugs in this class available for treatment of newly diagnosed CML. In 2012, Radotinib joined the class of novel agents in the inhibition of the BCR-ABL protein and was approved in South Korea for patients resistant to or intolerant of imatinib. Bosutinib received US FDA and EU European Medicines Agency approval on September 4, 2012 and 27 March 2013 respectively for the treatment of adult patients with Philadelphia chromosome-positive (Ph+) chronic myelogenous leukemia (CML) with resistance, or intolerance to prior therapy.

First-line treatment of AML consists primarily of chemotherapy, and is divided into two phases: induction and postremission (or consolidation) therapy. The goal of induction therapy is to achieve a complete remission by reducing the number of leukemic cells to an undetectable level; the goal of consolidation therapy is to eliminate any residual undetectable disease and achieve a cure. Hematopoietic stem cell transplantation is usually considered if induction chemotherapy fails or after a person relapses, although transplantation is also sometimes used as front-line therapy for people with high-risk disease. Efforts to use tyrosine kinase inhibitors in AML continue.

Combination chemotherapy regimens are effective in both newly diagnosed and relapsed CLL. Combinations of fludarabine with alkylating agents (cyclophosphamide) produce higher response rates and a longer progression-free survival than single agents:

- FC (fludarabine with cyclophosphamide)

- FR (fludarabine with rituximab)

- FCR (fludarabine, cyclophosphamide, and rituximab)

- CHOP (cyclophosphamide, doxorubicin, vincristine, and prednisolone)

Although the purine analogue fludarabine was shown to give superior response rates to chlorambucil as primary therapy, no evidence shows early use of fludarabine improves overall survival, and some clinicians prefer to reserve fludarabine for relapsed disease.

Chemoimmunotherapy with FCR has shown to improve response rates, progression-free survival, and overall survival in a large randomized trial in CLL patients selected for good physical fitness. This has been the first clinical trial demonstrating that the choice of a first-line therapy can improve the overall survival of patients with CLL.

Alkylating agents approved for CLL include bendamustine and cyclophosphamide.

Targeted therapy attacks cancer cells at a specific target, with the aim of not harming normal cells.

- Alemtuzumab is a mAb directed against CD52 used in CLL.

- Rituximab, ofatumumab, and obinutuzumab are antibodies against CD20 used to treat CLL.

- Ibrutinib, a Bruton's tyrosine kinase (BTK) inhibitor, is used to treat CLL.

- Idelalisib is a PI3K inhibitor. and is taken orally.

- Venetoclax is a Bcl-2 inhibitor used to treat people with CLL who have 17p deletion (deletion located on the chromosome 17 short arm) and who have been treated with at least one prior therapy.

In the past, antimetabolites (e.g., cytarabine, hydroxyurea), alkylating agents, interferon alfa 2b, and steroids were used as treatments of CML in the chronic phase, but since the 2000s have been replaced by Bcr-Abl tyrosine-kinase inhibitors drugs that specifically target BCR-ABL, the constitutively activated tyrosine kinase fusion protein caused by the Philadelphia chromosome translocation. Despite the move to replacing cytotoxic antineoplastics (standard anticancer drugs) with tyrosine kinase inhibitors sometimes hydroxyurea is still used to counteract the high leukocyte counts encountered during treatment with tyrosine kinase inhibitors like imatinib; in these situations it may be the preferred myelosuppressive agent due to its relative lack of leukemogenic effects and hence the relative lack of potential for secondary hematologic malignancies to result from treatment. IRIS, an international study that compared interferon/cytarabine combination and the first of these new drugs imatinib, with long-term follow up, demonstrated the clear superiority of tyrosine-kinase-targeted inhibition over existing treatments.

Radiation therapy (or radiotherapy) is used on painful bony areas, in high disease burdens, or as part of the preparations for a bone marrow transplant (total body irradiation). In the past, physicians commonly utilized radiation in the form of whole-brain radiation for central nervous system prophylaxis, to prevent occurrence and/or recurrence of leukemia in the brain. Recent studies showed that CNS chemotherapy provided results as favorable but with less developmental side-effects. As a result, the use of whole-brain radiation has been more limited. Most specialists in adult leukemia have abandoned the use of radiation therapy for CNS prophylaxis, instead using intrathecal chemotherapy.

Chemotherapy is the initial treatment of choice, and most ALL patients receive a combination of medications. There are no surgical options because of the body-wide distribution of the malignant cells. In general, cytotoxic chemotherapy for ALL combines multiple antileukemic drugs tailored to each patient. Chemotherapy for ALL consists of three phases: remission induction, intensification, and maintenance therapy.

Due to presence of CNS involvement in 10–40% of adult patients at diagnosis, most providers start Central nervous system (CNS) prophylaxis and treatment during the induction phase, and continue it during the consolidation/intensification period.

Adult chemotherapy regimens mimic those of childhood ALL; however, are linked with a higher risk of disease relapse with chemotherapy alone. It should be known that 2 subtypes of ALL (B-cell ALL and T-cell ALL) require special considerations when it comes to selecting an appropriate treatment regimen in adult patients. B-cell ALL is often associated with cytogenetic abnormalities (specifically, t(8;14), t (2;8) and t(8;22)), which require aggressive therapy consisting of brief, high-intensity regimens. T-cell ALL responds to cyclophosphamide-containing agents the most.

As the chemotherapy regimens can be intensive and protracted, many patients have an intravenous catheter inserted into a large vein (termed a central venous catheter or a Hickman line), or a Portacath, usually placed near the collar bone, for lower infection risks and the long-term viability of the device.

Males usually endure a longer course of treatment than females as the testicles can act as a reservoir for the cancer.

All FAB subtypes except M3 are usually given induction chemotherapy with cytarabine (ara-C) and an anthracycline (most often daunorubicin). This induction chemotherapy regimen is known as "7+3" (or "3+7"), because the cytarabine is given as a continuous IV infusion for seven consecutive days while the anthracycline is given for three consecutive days as an IV push. Up to 70% of people with AML will achieve a remission with this protocol. Other alternative induction regimens, including high-dose cytarabine alone, FLAG-like regimens or investigational agents, may also be used. Because of the toxic effects of therapy, including myelosuppression and an increased risk of infection, induction chemotherapy may not be offered to the very elderly, and the options may include less intense chemotherapy or palliative care.

The M3 subtype of AML, also known as acute promyelocytic leukemia (APL), is almost universally treated with the drug all-"trans"-retinoic acid (ATRA) in addition to induction chemotherapy, usually an anthracycline. Care must be taken to prevent disseminated intravascular coagulation (DIC), complicating the treatment of APL when the promyelocytes release the contents of their granules into the peripheral circulation. APL is eminently curable, with well-documented treatment protocols.

The goal of the induction phase is to reach a complete remission. Complete remission does not mean the disease has been cured; rather, it signifies no disease can be detected with available diagnostic methods. Complete remission is obtained in about 50%–75% of newly diagnosed adults, although this may vary based on the prognostic factors described above. The length of remission depends on the prognostic features of the original leukemia. In general, all remissions will fail without additional consolidation therapy.

The role of chemotherapy or other pharmacologic treatments against JMML before bone marrow transplant has not been studied completely and its importance is still unknown. Chemotherapy by itself has proven unable to bring about long-term survival in JMML.

- Low-dose conventional chemotherapy: Studies have shown no influence from low-dose conventional chemotherapy on JMML patients’ length of survival. Some combinations of 6-mercaptopurine with other chemotherapy drugs have produced results such as decrease in organ size and increase or normalization of platelet and leukocyte count.

- Intensive chemotherapy: Complete remission with ongoing durability from JMML has not been possible through use of intensive chemotherapy, but it is still used at times because it has improved the condition of a small but significant number of JMML patients who do not display an aggressive disease. The COG JMML study administers 2 cycles of fludarabine and cytarabine for 5 consecutive days along with 13-cis retinoic acid during and afterwards. The EWOG-MDS JMML study, however, does not recommend intensive chemotherapy before bone marrow transplant.

- 13-cis retinoic acid (Isotretinoin): In the lab, 13-cis-retinoic acid has inhibited the growth of JMML cells. The COG JMML study therefore includes 13-cis-retinoic acid in its treatment protocol, though its therapeutic value for JMML remains controversial.

The theory behind splenectomy in JMML is that the spleen may trap leukemic cells, leading to the spleen's enlargement, by harboring dormant JMML cells that are not eradicated by radiation therapy or chemotherapy for the active leukemia cells, thus leading to later relapse if the spleen is not removed. However, the impact of splenectomy on post-transplant relapse, though, is unknown. The COG JMML study includes splenectomy as a standard component of treatment for all clinically stable patients. The EWOG-MDS JMML study allows each child’s physician to determine whether or not a splenectomy should be done, and large spleens are commonly removed prior to bone marrow transplant. When a splenectomy is scheduled, JMML patients are advised to receive vaccines against "Streptococcus pneumoniae" and "Haemophilus influenza" at least 2 weeks prior to the procedure. Following splenectomy, penicillin may be administered daily in order to protect the patient against bacterial infections that the spleen would otherwise have protected against; this daily preventative regimen will often continue indefinitely.

Natural killer (NK) cell therapy is used in pediatrics for children with relapsed lymphoid leukemia. These patients normally have a resistance to chemotherapy, therefore, in order to continue on, must receive some kind of therapy. In some cases, NK cell therapy is a choice.

NK cells are known for their ability to eradicate tumor cells without any prior sensitization to them. One problem when using NK cells in order to fight off lymphoid leukemia is the fact that it is hard to amount enough of them to be effective. One can receive donations of NK cells from parents or relatives through bone marrow transplants. There are also the issues of cost, purity and safety. Unfortunately, there is always the possibility of Graft vs host disease while transplanting bone marrow.

NK cell therapy is a possible treatment for many different cancers such as Malignant glioma.

The treatment a child will undergo is based on the child's age, overall health, medical history, their tolerance for certain medications, procedures, and therapies, along with the parents' opinion and preference.

- Chemotherapy is a treatment that uses drugs to interfere with the cancer cells ability to grow and reproduce. Chemotherapy can be used alone or in combination with other therapies. Chemotherapy can be given either as a pill to swallow orally, an injection into the fat or muscle, through an IV directly into the bloodstream, or directly into the spinal column.

- A stem cell transplant is a process by which healthy cells are infused into the body. A stem-cell transplant can help the human body make enough healthy white blood cells, red blood cells, or platelets, and reduce the risk of life-threatening infections, anemia, and bleeding. It is also known as a bone-marrow transplant or an umbilical-cord blood transplant, depending on the source of the stem cells. Stem cell transplants can use the cells from the same person, called an autologous stem cell transplant or they can use stem cells from other people, known as an allogenic stem cell transplant. In some cases, the parents of a child with childhood leukemia may conceive a saviour sibling by preimplantation genetic diagnosis to be an appropriate match for the HLA antigen.

Most patients with T-cell prolymphocytic leukemia require immediate treatment.

T-cell prolymphocytic leukemia is difficult to treat, and it does not respond to most available chemotherapeutic drugs. Many different treatments have been attempted, with limited success in certain patients: purine analogues (pentostatin, fludarabine, cladribine), chlorambucil, and various forms of combination chemotherapy regimens, including cyclophosphamide, doxorubicin, vincristine, prednisone (CHOP), etoposide, bleomycin (VAPEC-B).

Alemtuzumab (Campath), an anti-CD52 monoclonal antibody that attacks white blood cells, has been used in treatment with greater success than previous options. In one study of previously treated people with T-PLL, people who had a complete response to alemtuzumab survived a median of 16 months after treatment.

Some patients who successfully respond to treatment also undergo stem cell transplantation to consolidate the response.

If a patient is resistant to either cladribine or pentostatin, then second-line therapy is pursued.

Monoclonal antibodies The most common treatment for cladribine-resistant disease is infusing monoclonal antibodies that destroy cancerous B cells. Rituximab is by far the most commonly used. Most patients receive one IV infusion over several hours each week for four to eight weeks. A 2003 publication found two partial and ten complete responses out of 15 patients with relapsed disease, for a total of 80% responding. The median patient (including non-responders) did not require further treatment for more than three years. This eight-dose study had a higher response rate than a four-dose study at Scripps, which achieved only 25% response rate. Rituximab has successfully induced a complete response in Hairy Cell-Variant.

Rituximab's major side effect is serum sickness, commonly described as an "allergic reaction", which can be severe, especially on the first infusion. Serum sickness is primarily caused by the antibodies clumping during infusion and triggering the complement cascade. Although most patients find that side effects are adequately controlled by anti-allergy drugs, some severe, and even fatal, reactions have occurred. Consequently, the first dose is always given in a hospital setting, although subsequent infusions may be given in a physician's office. Remissions are usually shorter than with the preferred first-line drugs, but hematologic remissions of several years' duration are not uncommon.

Other B cell-destroying monoclonal antibodies such as Alemtuzumab, Ibritumomab tiuxetan and I-131 Tositumomab may be considered for refractory cases.

Interferon-alpha Interferon-alpha is an immune system hormone that is very helpful to a relatively small number of patients, and somewhat helpful to most patients. In about 65% of patients, the drug helps stabilize the disease or produce a slow, minor improvement for a partial response.

The typical dosing schedule injects at least 3 million units of Interferon-alpha (not pegylated versions) three times a week, although the original protocol began with six months of daily injections.

Some patients tolerate IFN-alpha very well after the first couple of weeks, while others find that its characteristic flu-like symptoms persist. About 10% of patients develop a level of depression. It is possible that, by maintaining a steadier level of the hormone in the body, that daily injections might cause fewer side effects in selected patients. Drinking at least two liters of water each day, while avoiding caffeine and alcohol, can reduce many of the side effects.

A drop in blood counts is usually seen during the first one to two months of treatment. Most patients find that their blood counts get worse for a few weeks immediately after starting treatment, although some patients find their blood counts begin to improve within just two weeks.

It typically takes six months to figure out whether this therapy is useful. Common criteria for treatment success include:

- normalization of hemoglobin levels (above 12.0 g/dL),

- a normal or somewhat low platelet count (above 100 K/µL), and

- a normal or somewhat low absolute neutrophil count (above 1.5 K/µL).

If it is well tolerated, patients usually take the hormone for 12 to 18 months. An attempt may be made then to end the treatment, but most patients discover that they need to continue taking the drug for it to be successful. These patients often continue taking this drug indefinitely, until either the disease becomes resistant to this hormone, or the body produces an immune system response that limits the drug's ability to function. A few patients are able to achieve a sustained clinical remission after taking this drug for six months to one year. This may be more likely when IFN-alpha has been initiated shortly after another therapy. Interferon-alpha is considered the drug of choice for pregnant women with active HCL, although it carries some risks, such as the potential for decreased blood flow to the placenta.

Interferon-alpha works by sensitizing the hairy cells to the killing effect of the immune system hormone TNF-alpha, whose production it promotes. IFN-alpha works best on classic hairy cells that are not protectively adhered to vitronectin or fibronectin, which suggests that patients who encounter less fibrous tissue in their bone marrow biopsies may be more likely to respond to Interferon-alpha therapy. It also explains why non-adhered hairy cells, such as those in the bloodstream, disappear during IFN-alpha treatment well before reductions are seen in adhered hairy cells, such as those in the bone marrow and spleen.

Several treatments are available, and successful control of the disease is common.

Not everyone needs treatment immediately. Treatment is usually given when the symptoms of the disease interfere with the patient's everyday life, or when white blood cell or platelet counts decline to dangerously low levels, such as an absolute neutrophil count below one thousand cells per microliter (1.0 K/uL). Not all patients need treatment immediately upon diagnosis.

Treatment delays are less important than in solid tumors. Unlike most cancers, treatment success does not depend on treating the disease at an early stage. Because delays do not affect treatment success, there are no standards for how quickly a patient should receive treatment. However, waiting too long can cause its own problems, such as an infection that might have been avoided by proper treatment to restore immune system function. Also, having a higher number of hairy cells at the time of treatment can make certain side effects somewhat worse, as some side effects are primarily caused by the body's natural response to the dying hairy cells. This can result in the hospitalization of a patient whose treatment would otherwise be carried out entirely at the hematologist's office.

Single-drug treatment is typical. Unlike most cancers, only one drug is normally given to a patient at a time. While monotherapy is normal, combination therapy—typically using one first-line therapy and one second-line therapy—is being studied in current clinical trials and is used more frequently for refractory cases. Combining rituximab with cladribine or pentostatin may or may not produce any practical benefit to the patient. Combination therapy is almost never used with a new patient. Because the success rates with purine analog monotherapy are already so high, the additional benefit from immediate treatment with a second drug in a treatment-naïve patient is assumed to be very low. For example, one round of either cladribine or pentostatin gives the median first-time patient a decade-long remission; the addition of rituximab, which gives the median patient only three or four years, might provide no additional value for this easily treated patient. In a more difficult case, however, the benefit from the first drug may be substantially reduced and therefore a combination may provide some benefit.

If a patient has the symptoms like leukemia, such as persistent fever or difficulty of hemostais, he has to see the doctors.

BAL is very hard to treat. Most of patients receive treatment based on the morphology of blasts and get AML or ALL induction chemotherapy. The induction drug for AML such as cytarabine and anthracycline, drug for ALL such as prednisolone, dexamethasone, vincristine, asparaginase or daunorubicin is common for BAL remission induction therapy. Recently, researches showed that using both myeloid and lymphoid induction therapy may be better for prognosis.

Chemotherapy is strong side effects such as typhlitis, gastrointestinal distress, anemia, fatigue, hair loss, nausea and vomiting, etc. Thus, the different dose and times of chemotherapy for different individuals is important.

If the patients enter fully remission, the consolidation with stem cell transplantation is highly recommended.

While investigational drug therapies exist, no curative drug treatment exists for any of the MPDs. The goal of treatment for ET and PV is prevention of thrombohemorrhagic complications. The goal of treatment for MF is amelioration of anemia, splenomegaly, and other symptoms. Low-dose aspirin is effective in PV and ET. Tyrosine kinase inhibitors like imatinib have improved the prognosis of CML patients to near-normal life expectancy.

Recently, a "JAK2" inhibitor, namely ruxolitinib, has been approved for use in primary myelofibrosis. Trials of these inhibitors are in progress for the treatment of the other myeloproliferative neoplasms.

As described above, chloromas should always be considered manifestations of systemic disease, rather than isolated local phenomena, and treated as such. In the patient with newly diagnosed leukemia and an associated chloroma, systemic chemotherapy against the leukemia is typically used as the first-line treatment, unless an indication for local treatment of the chloroma (e.g. compromise of the spinal cord) emerges. Chloromas are typically quite sensitive to standard antileukemic chemotherapy. Allogeneic hematopoietic stem cell transplantation should be considered in fit patients with suitable available donor, as long term remissions have been reported.

If the chloroma is persistent after completion of induction chemotherapy, local treatment, such as surgery or radiation therapy, may be considered, although neither has an effect on survival.

Patients presenting with a primary chloroma typically receive systemic chemotherapy, as development of acute leukemia is nearly universal in the short term after detection of the chloroma.

Patients treated for acute leukemia who relapse with an isolated chloroma are typically treated with systemic therapy for relapsed leukemia. However, as with any relapsed leukemia, outcomes are unfortunately poor.

Patients with "preleukemic" conditions, such as myelodysplastic syndromes or myeloproliferative syndromes, who develop a chloroma are often treated as if they have transformed to acute leukemia.

Treatment options that have been tried include zidovudine and the CHOP regimen. Pralatrexate has also been investigated. Most therapy is directed towards the cancer rather than the virus itself.

Recently, it has been reported that the traditional glucocorticoid-based chemotherapy toward ATL are largely mediated by thioredoxin binding protein-2 (TBP-2/TXNIP/VDUP1), suggesting the potential use of a TBP-2 inducer as a novel therapeutic target.

Recently, mogamulizumab, has been approved for the treatment of ATL in Japan.

At a medical conference in December 2013, researchers reported anywhere from 21-50% of ATL patients have disease expressing CD30. This suggests treatment with CD30-targeting brentuximab vedotin may be beneficial.

ANKL is treated similarly to most B-cell lymphomas. Anthracycline-containing chemotherapy regimens are commonly offered as the initial therapy. Some patients may receive a stem cell transplant.

Most patients will die 2 years after diagnosis.

Alemtuzumab has been investigated for use in treatment of refractory T-cell large granular lymphocytic leukemia.

Immunoglobulin E (IgE) is important in mast cell function. Immunotherapy with anti-IgE immunoglobulin raised in sheep resulted in a transient decrease in the numbers of circulating mast cells in one patient with mast cell leukemia. Although splenectomy has led to brief responses in patients with mast cell leukemia, no firm conclusions as to the efficacy of this treatment are possible. Chemotherapy with combination of cytosine arabinoside and either idarubicin, daunomycin, or mitoxantrone as for acute myeloid leukemia has been used. Stem cell transplantation is an option, although no experience exists concerning responses and outcome.

Generally, acute myeloid leukemia is treated using chemotherapy consisting of an induction phase and consolidation phase (Dohner et al., 2009). Patients may also consider hematopoietic stem cell transplantation as a second mode of tackling the cancer. The most novel research is being done in tyrosine kinase inhibitors; however M2 acute myeloid leukemia treatment research involves molecules that inhibit the fusion oncoprotein AML1-ETO. Therefore, in terms of M2 subtype acute myeloid leukemia, the most prominent target is the abnormal AML1-ETO fusion protein. Similarly, chronic myeloid leukemia (CML) is comparable to acute myeloid leukemia M2 because it also forms a fusion oncoprotein – BCR-Abl. The developed tyrosine kinase inhibitor, imatinib mesylate, has had a tremendous effect on stopping cancer progression in the majority of chronic myeloid leukemia patients. BCR-Abl is constitutively active due chromosome translocation; therefore it over-phosphorylates the tyrosine kinase. Imatinib mesylate works to block BCR-Abl’s activity by blocking the active kinase domain (Fava et al., 2011).

Celastrol is a compound extracted from Tripterygium wilfordii that has anti-cancer properties. It was found to inhibit cell proliferation through the down regulation of AML1-ETO fusion oncoprotein. Celastrol inhibits the fusion oncoprotein by inducing mitochondrial instability and initiating caspase activity The decrease of AML1-ETO also results in lower levels of C-KIT kinases, Akt/PKB, STAT3, and Erk1/2 – all of which are involved in cell signaling and gene transcription (Yu et al., 2016).

Histone deacetylase inhibitors such as valproic acid (VPA), vorinostat, and all-trans retinoic acid (ATRA) are effective in targeting acute myeloid leukemia with the AML1-ETO fusion protein. The HDAC inhibitors are known to induce apoptosis through accumulation of DNA damage, inhibition of DNA repair, and activation of caspases. These inhibitors are extra sensitive to the fusion proteins. Vorinostat has been proven to cause a greater accumulation of DNA damage in fusion protein expressing cells and is directly correlated with the reduction of DNA repair enzymes (Garcia et al., 2008). Romidepsin, a drug in phase two clinical trials, has demonstrated higher efficacy in patients with AML1-ETO fusion protein leukemia (Odenike et al., 2008). Although many clinical evaluations have proven HDAC inhibitors have a promising effect on M2 subtype acute myeloid leukemia, it has not been approved as an official treatment.

In t(6;9) acute myeloid leukemia, FLT3-ITD and the DEK-NUP214 protein are potential targets for treatment. Sorafenib is a kinase inhibitor used as a treatment for kidney and liver cancer. The kinase inhibitor blocks serine-threonine kinase RAF-1 as well as FLT-ITD (Kindler, 2010). The drug has been proven to be effective in reducing FLT3-ITD overexpression (Metzelder et al., 2009). In patients with DEK-NUP214, it was found that the fusion oncoprotein caused an upregulation of mTORC1 (Sanden et al., 2013). Thus, a mTORC inhibitor could be a potential treatment.
