This information is about treating acute lymphocytic leukemia ALL in adults. The main treatment for acute lymphocytic leukemia ALL in adults is typically long-term chemotherapy chemo.
In recent years, doctors have begun to use more intensive chemo regimens, which has led to more responses to treatment.
But these regimens are also more likely to cause side effects, such as low white blood cell counts. Patients may need to take other drugs to help prevent or treat these side effects. The total treatment usually takes about 2 years, with the maintenance phase taking up most of this time.
Treatment may be more or less intense, depending on the subtype of ALL and other prognostic factors. ALL can spread to the area around the brain and spinal cord.
Sometimes Treatment for leukemia in adults has already occurred by the time ALL is first diagnosed. This spread is found when the doctor does a lumbar puncture spinal tap and leukemia cells are found in the cerebrospinal Treatment for leukemia in adults CSFthe liquid that surrounds the brain and spinal cord. The treatment of this is discussed below. Even if leukemia cells aren't found in the CSF at diagnosis, it's possible that that they might spread there later on.
This is why an important part of treatment for ALL is central nervous system CNS prophylaxis — treatment that lowers the risk of the leukemia spreading to the area around the brain or spinal cord. This is also described in more detail below. The goal of induction chemo is to get the leukemia into remission complete remission. This means that leukemia cells are no longer found in bone marrow samples on a bone marrow biopsythe normal marrow cells return, and the blood counts return to normal levels.
But a remission is not necessarily a cure, as leukemia cells may still be hiding somewhere in the body.
Induction chemo usually lasts for a month or so. Different combinations of chemo drugs might be used, but they typically include:.
Treatment for leukemia in adults ALL patients whose leukemia cells have the Philadelphia chromosomea targeted drug such as imatinib Gleevec or dasatinib Spycel is often included as well. For patients who are older typically over 65 or who have other serious health conditions, many of the same drugs are used for induction, although the doses of the drugs might need to be reduced.
This first month of treatment is intensive and requires frequent visits to the doctor. You may spend some or much of this time in the hospital, because serious infections or other complications can occur. It's very important to take all medicines as prescribed. Sometimes complications can be serious enough to be life-threatening, but with recent advances in supportive care nursing care, nutrition, antibiotics, growth factors, red blood cell and platelet transfusions as needed, etc.
Most often, leukemia goes into remission with induction chemotherapy. But because leukemia cells may still be hiding somewhere Treatment for leukemia in adults the body, further treatment is needed. CNS treatment or prophylaxis: This is often started during induction and continued through the other phases of treatment. It may include one or more of the following:. If the leukemia goes into remission, the next phase often consists of another fairly short course of chemo, using many of the same drugs that were used for induction therapy.
This typically lasts for a few months. Usually the drugs are given in high doses so that the treatment is still fairly intense. A targeted drug like imatinib is also continued for patients whose leukemia cells have the Philadelphia chromosome. Some patients in remission, such as those who have certain subtypes of ALL or other poor prognostic factors, are still at high risk for the leukemia relapsing coming back.
Instead of standard chemo, doctors may suggest an allogeneic stem cell transplant SCT at this time, especially for those who have a brother or sister who would be a good donor match. An autologous SCT may be another option.
Patients considering this procedure should think about having it done at a center that has done a lot of stem cell transplants. After consolidation, the patient is generally put on a maintenance chemotherapy program of methotrexate and 6-mercaptopurine 6-MP.
In some cases, this Treatment for leukemia in adults be combined with other drugs such as vincristine and prednisone. For ALL patients whose leukemia cells have the Philadelphia chromosome, a targeted drug like imatinib is often included as well.
Maintenance usually lasts for about 2 years. This means leukemia cells can no longer be seen in their bone marrow. Again, these rates can vary a lot, depending on the subtype of ALL and other prognostic factors. For example, cure rates tend to be higher in younger patients.
Monoclonal antibodies such as blinatumomab Blincyto or inotuzumab ozogamicin Besponsa may be an option for patients with B-cell ALL. A stem cell transplant may be tried if the leukemia can be put into at least partial remission.
Clinical trials of new treatment approaches may also be considered. If leukemia goes into remission with the initial treatment but then comes back relapses or recursit will most often do so in the bone marrow and blood.
Occasionally, the brain or spinal fluid will be the first place it recurs.

In these cases, it is sometimes possible to put the leukemia into remission again with more chemotherapy chemoalthough this remission is not likely to last. The approach to treatment may depend on how soon the leukemia returns after the first treatment. If the relapse occurs after a long interval, the same or similar treatment may be used to try for a second remission. If the time interval is shorter, more aggressive chemo with other drugs may be needed. Immunotherapy might be another option for some patients.
For example, a monoclonal antibody such as blinatumomab Blincyto or inotuzumab ozogamicin Besponsa may be an option for some patients with B-cell ALL, while CAR T-cell therapy might Treatment for leukemia in adults an option for patients who are 25 or younger.
ALL patients with the Philadelphia chromosome who were taking a targeted drug like imatinib Gleevec are often switched to a different targeted drug. If a second remission Treatment for leukemia in adults be achieved, most doctors will advise some type of stem cell transplant if possible. If a stem cell transplant is not an option, a patient may want to consider taking part in a clinical trial of newer treatments. At some point, it may become clear that further treatment, even in clinical trials, is extremely unlikely to cure the leukemia.
At that time, the focus of treatment may shift to controlling the leukemia and its symptoms for as long as possible, rather than trying to cure it. This may be called palliative treatment or supportive care. For example, the doctor may advise less intensive chemo to try to slow the leukemia growth instead of trying to cure it. As the leukemia grows in the bone marrow it may cause pain.
It's important that you be as comfortable as possible. Treatments that may be helpful include radiation and appropriate pain-relieving medicines.
Other common symptoms from leukemia are low blood counts and fatigue. Medicines or blood transfusions may be needed to help correct these problems. Nausea and loss of appetite can be treated with medicines and high-calorie food supplements.

Treatment typically takes place in 3 phases: Induction remission induction Consolidation intensification Maintenance The total treatment usually takes Treatment for leukemia in adults 2 years, with the maintenance phase taking up most of this time.
Induction The goal of induction chemo is to get the leukemia into remission complete remission. Different combinations of chemo drugs might be used, but they typically include: It may include one or more of the following: Chemo injected directly into the CSF called intrathecal chemotherapy. The drug used most often is methotrexate, but sometimes cytarabine or a steroid such as prednisone may be used as well.
Intrathecal chemo can be given during a lumbar puncture spinal tap or through an Ommaya reservoir as discussed in the surgery section. High-dose IV methotrexate, cytarabine, or other chemo drugs Radiation therapy to the brain and spinal cord Consolidation intensification If the leukemia goes into remission, the next phase often consists of another fairly short course of chemo, using Treatment for leukemia in adults of the same drugs that were used for induction therapy.
Maintenance After consolidation, the patient is generally put on a maintenance chemotherapy program of methotrexate and 6-mercaptopurine 6-MP. Palliative treatment At some point, it may become clear that further treatment, even in clinical trials, is extremely unlikely to cure the leukemia. The main treatment for acute lymphocytic leukemia (ALL) in adults involves the long-term use of chemotherapy (chemo).
For ALL patients whose leukemia cells have the Philadelphia chromosome, a targeted drug such as imatinib (Gleevec) is often included as well. Response rates to.
