What is the rarest form of acute leukemia?

Acute promyelocytic leukemia (APL) is a rare subtype of AML. It’s associated with a specific genetic change called the PML/RARA fusion gene. In APL, immature WBCs called promyelocytes begin to gather in the blood and bone marrow.

What are the different types of acute leukemia?

There are 4 main types of leukemia, based on whether they are acute or chronic, and myeloid or lymphocytic:

  • Acute myeloid (or myelogenous) leukemia (AML)
  • Chronic myeloid (or myelogenous) leukemia (CML)
  • Acute lymphocytic (or lymphoblastic) leukemia (ALL)
  • Chronic lymphocytic leukemia (CLL)

What is the most severe type of leukemia?

The most common form of acute (fast-developing) leukemia among adults , AML is also the most critical because it progresses rapidly.

Which leukemia is hardest to treat?

Two recently identified types of acute lymphoblastic leukemia (ALL) are extremely difficult to treat with existing drugs. Children who have Philadelphia chromosome-like ALL (Ph-like ALL) and early T-cell precursor ALL (ETP ALL) are more likely to face recurrence and less likely to survive long term.

Which is worse all or AML?

Is one more serious than the other? Both ALL and AML are very serious conditions that develop rapidly . According to a 2021 review, AML is the most common type of leukemia among adults, accounting for around 80% of all cases. Authors of the review observe that age plays an important role in survival rates for AML.

Which type of leukemia has the best prognosis?

The survival rates are highest for acute lymphoblastic leukemia (ALL). The rates vary depending on person’s age, the type of leukemia they have, and if (and how far) the leukemia has spread at the time of diagnosis. A child who has lived at least five years after a diagnosis of acute leukemia is probably cured.

How many types of acute myeloid leukemia are there?

One of the main things that differentiates AML from the other main forms of leukemia is that it has eight different subtypes, which are based on the cell that the leukemia developed from.

IS ALL or AML worse?

What is the rarest type of leukemia?

Rare types of leukemia. Among the many different types of leukemia, some are less common than others. Three rarer leukemia types—prolymphocytic leukemia (PLL), large granular lymphocyte leukemia (LGL) and hairy cell leukemia (HCL)—share some of the same characteristics as lymphocytic leukemias and are sometimes considered subtypes of chronic or acute lymphocytic leukemia (CLL and ALL).

Which is the least serious type of leukemia?

acute lymphocytic leukemia (ALL)

  • acute myeloid,or myelogenous,leukemia (AML)
  • chronic lymphocytic leukemia (CLL)
  • chronic myeloid,or myelogenous,leukemia (CML)
  • What type of person is most likely to get leukemia?

  • Ionizing radiation.
  • Medications.
  • Workplace exposures.

  • Blood disorders.
  • Viruses.
  • What are the three types of leukemia?
