What is the duration of treatment for acute myeloid leukemia (APL)?
A bone marrow biopsy is usually done about a month after starting treatment, to see if the leukemia is in remission. Induction is typically continued until the APL is in remission, which might take up to 2 months. Once APL is in remission, consolidation is needed to keep it in remission and try to get rid of the remaining leukemia cells.
What is the prognosis of acute promyelocytic leukemia (APL) without Ara-C?
Several study groups, particularly the Spanish PETHEMA group (in LPA 96 and 99 clinical trials [26, 27]), reported high CR rates and low relapse rates in patients with newly diagnosed APL treated with ATRA and IDA combination without ARA-C.
What is the prognosis of acute lymphocytic leukemia (ALL)?
Acute lymphocytic leukemia (ALL): In general, the disease goes into remission in nearly all children who have it. More than four out of five children live at least 5 years. The prognosis for adults is not as good. Only 25 to 35 percent of adults live 5 years or longer.
When are steroids indicated in the treatment of acute promyelocytic leukemia (APL)?
Corticosteroids (10 mg of dexamethasone IV twice daily) should be started immediately at the earliest clinical suspicion of incipient APL differentiation syndrome; once the syndrome has resolved, steroids can be discontinued and ATO/ATRA recommenced IIa–B Unchanged 1.14.
How long is treatment for APL leukemia?
The most common options for maintenance therapy are ATRA alone, or ATRA along with chemo (6-mercaptopurine (6-MP) and/or methotrexate). Maintenance therapy is typically given for about a year.
How long do you stay in the hospital for leukemia?
Patients will often need to stay in the hospital for 3 to 4 weeks during treatment. However, depending on the situation, many patients can leave the hospital.
What is the cure rate for APL?
Treatment Outcomes Because of advances in diagnostic techniques and modern treatments, APL is today considered to be the most curable subtype of acute myeloid leukemia in adults, with complete remission rates of 90 percent and cure rates of approximately 80 percent and even higher among low-risk patients.
How long can you live with APL leukemia?
APL is now considered a highly curable disease, with 2-year event-free survival rates of 75–84%. Early mortality is common in APL and is frequently related to hemorrhagic complications. Prior to ATRA therapy, early death (ED) related to hemorrhage occurred in up to 26% of cases.
How long does leukemia chemotherapy take?
Chemo treatment for ALL is typically divided into 3 phases: Induction, which is short and intensive, usually lasts about a month. Consolidation (intensification), which is also intensive, typically lasts for a few months. Maintenance (post-consolidation), which is less intensive, typically lasts for about 2 years.
How long do you stay in hospital with chemo?
If you are a day patient, you are likely to be at the hospital between four and six hours, sometimes longer if the treatment is complex, or if you are taking part in a research study. Before you are given your chemotherapy, you will usually have blood tests and see the doctor.
Can APL be cured as of 2021?
Because of advances in diagnostic techniques and modern treatments, APL is now considered the most curable subtype of AML in adults, with complete remission rates of 90 percent following treatment and cure rates of approximately 80 percent reported in clinical trials.
Can APL be completely cured?
The vast majority of patients with APL achieve a complete remission after induction therapy and molecular remission after completion of consolidation therapy.
Why is APL an emergency?
In fact, APL represents a medical emergency with a high rate of early mortality, due mainly to hemorrhagic complications from a characteristic coagulopathy.
Can you survive acute promyelocytic leukemia?
Unlike most leukemias, acute promyelocytic leukemia (APL) has a very good prognosis, with long-term survival rates up to 90% following treatment.
How often does APL relapse?
However, for patients treated with ATRA plus anthracycline chemotherapy, relapse occurs in 5 to 10 percent of patients with APL and in 20 to 30 percent of those with high-risk APL (ie, presentation with a white blood cell count >10,000/microL and a platelet count <40,000/microL).
What is the most treatable leukemia?
While it is similar in many ways to the other subtypes, APL is distinctive and has a very specific treatment regime. Treatment outcomes for APL are very good, and it is considered the most curable type of leukemia. Cure rates are as high as 90%.
What is the treatment for acute myeloid leukemia?
Many people with APL are first treated with a drug called all-trans-retinoic acid (ATRA), also called tretinoin (Vesanoid®). ATRA is given in combination with another drug called arsenic trioxide ...
What is the treatment for cancer that can't be detected?
This means that the cancer can no longer be detected, which is called remission. After the disease is in remission, they are then given consolidation therapy . This includes additional cycles of ATRA and arsenic trioxide.
What is intrathecal chemotherapy?
This process is called intrathecal chemotherapy. After consolidation therapy, people with high-risk disease may stay on maintenance therapy for a few years to keep the cancer from coming back. This therapy is given intermittently and combines ATRA and low-dose chemotherapy.
What is the treatment for acute promyelocytic leukemia?
Treatment for Acute Promyelocytic Leukemia. APL is treated differently than other forms of AML. Many people with APL are first treated with a drug called all-trans-retinoic acid, also called tretinoin (Vesanoid ® ), which is given in combination with another drug called arsenic trioxide (Trisenox ® ). Both of these drugs were pioneered ...
What is APL in medical terms?
Acute promyelocytic leukemia (APL) is an aggressive type of acute myeloid leukemia (AML). It happens when there are too many of the blood-forming cells called promyelocytes in the blood and bone marrow.
Why do people with APL have a lot of bleeding?
This is because of the shortage of platelets in their blood and changes in the level of abnormal proteins in the blood.
What is the PML gene in APL?
Chromosomes are inside all cells and carry our genes. In APL, the PML gene on chromosome 15 fuses with the RARA gene on chromosome 17. A defective protein forms as a result. Tests can detect this protein in the blood and bone marrow. Learn more about diagnosing leukemia.
What is APL post remission?
Consolidation (post-remission therapy) The acute promyelocytic leukemia (APL) subtype of AML is treated differently. Treatment for AML usually needs to start as quickly as possible after it is diagnosed because it can progress very quickly. Sometimes another type of treatment needs to be started even before the chemo has had a chance to work.
How long does it take for leukemia to go down?
This is called leukostasis. Chemo can take a few days to lower the number of leukemia cells in the blood.
What happens to the white blood cells induction?
Induction destroys most of the normal bone marrow cells as well as the leukemia cells, so most patients develop dangerously low blood counts, and may be very ill. Most patients need antibiotics and blood product transfusions. Drugs to raise white blood cell counts (called growth factors) may also be used.
What happens when blood cells recover from leukemia?
When the blood cell counts recover, the doctor will again check cells in a bone marrow sample to see if the leukemia is in remission. Remission induction usually does not destroy all the leukemia cells, and a small number often remain.
How long does it take for blood count to go down after chemo?
Blood counts tend to stay low for a few weeks. About a week after chemo is done, the doctor will do a bone marrow biopsy. It should show few bone marrow cells ( hypocellular bone marrow) and only a small portion of blasts (making up no more than 5% of the bone marrow) for the leukemia to be considered in remission.
How old do you have to be to get chemo?
How intense the treatment is can depend on a person’s age and health. Doctors often give the most intensive chemo to people under the age of 60, but some older patients in good health may benefit from similar or slightly less intensive treatment.
How many IV lines are needed for pheresis?
Two intravenous (IV) lines are required – the blood is removed through one IV, goes through the machine, and then is returned to the patient through the other IV. Sometimes, a single large catheter is placed in a vein in the neck or under the collar bone for the pheresis, instead of using IV lines in both arms.

In adults, leukemia is most common in people older than 55 years, with the average age of diagnosis being 66 years. It is also one of the most common cancers in children and adults younger than 20 years. The survival rate is higher for younger people. According to the National Cancer Institute, the percentage of deaths by age group is as follows: ...
What are the different types of leukemia?
There are four common types of leukemia which include: Acute lymphocytic leukemia (ALL): In this type of leukemia, immature lymphoid cells grow rapidly in the blood. It is the most common type of leukemia in children and rarely affects adults. Acute myeloid leukemia (AML):
How long does it take for cancer to go into remission?
About 80 percent who go into remission will do so within 1 month of therapy . In some people, however, the disease will return, lowering the cure rate. Chronic lymphocytic leukemia (CLL): On average, people with this cancer survive 9 years, although some have lived for decades, cancer always comes back at some point.
