The slow-growing form of chronic lymphocytic leukemia (CLL) is the least serious type of leukemia. It is a disease of older people; the average age at diagnosis is around 71. CLL is a malignancy of mature lymphocytes, which usually grow and divide slowly, resulting in a slowly progressive disease.
The onset of leukemia can be acute (sudden onset) or chronic (slow onset). In acute leukemia, cancer cells multiply quickly. In chronic leukemia, the disease progresses slowly and early symptoms may be very mild.
Acute lymphocytic leukemia (ALL)
However, ALL may be easier to treat than AML. Also, while CLL is more common in adults, ALL is more prevalent in children . However, certain risk factors may increase the risk of ALL in adults, such as being an adult white male over the age of 70 .
CLL and SLL are slow-growing (low-grade or 'indolent') cancers. Many doctors group them together as a type of non-Hodgkin lymphoma. They usually behave like a long-term (chronic) condition that needs treatment from time-to-time to keep it under control. CLL and SLL are treated in the same way.
Chronic lymphocytic leukemia (CLL) is a type of cancer of the blood and bone marrow — the spongy tissue inside bones where blood cells are made. The term "chronic" in chronic lymphocytic leukemia comes from the fact that this leukemia typically progresses more slowly than other types of leukemia.
Chronic lymphocytic leukemia (CLL) can rarely be cured. Still, most people live with the disease for many years. Some people with CLL can live for years without treatment, but over time, most will need to be treated. Most people with CLL are treated on and off for years.
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.
Chemotherapy. Chemotherapy is the major form of treatment for leukemia. This drug treatment uses chemicals to kill leukemia cells. Depending on the type of leukemia you have, you may receive a single drug or a combination of drugs.
As with other types of cancer, there's currently no cure for leukemia. People with leukemia sometimes experience remission, a state after diagnosis and treatment in which the cancer is no longer detected in the body. However, the cancer may recur due to cells that remain in your body.
Leukemia is the most common type of cancer in children. But most kids and teens treated for leukemia are cured of the disease.
The slow-growing form of chronic lymphocytic leukemia (CLL) is the least serious type of leukemia. It is a disease of older people; the average age at diagnosis is around 71. CLL is a malignancy of mature lymphocytes, which usually grow and divide slowly, resulting in a slowly progressive disease.
Chronic lymphocytic leukaemia (CLL) is a type of slow-growing leukaemia that affects developing B-lymphocytes. B lymphocytes (also known as B-cells) are specialised white blood cells.
However, there are many varieties of leukemia, not all of which are threatening. Chronic lymphocytic leukemia is, in general, one of those nonthreatening leukemias.
In CLL, the leukemia cells grow out of control and crowd out normal blood cells. These cells often build up slowly over time. Many people don't have any symptoms for at least a few years. In time, the cells can spread to other parts of the body, including the lymph nodes, liver, and spleen.
Stage 0 – A patient has high levels of white blood cells, but no other physical symptoms. Stage 1 – A patient has high levels of white blood cells and enlarged lymph nodes. Stage 2 – A patient has high levels of white blood cells and is anemic. He or she may also have enlarged lymph nodes.
Many people enjoy long and healthy lives after being successfully treated for their blood cancer. Sometimes, however, the treatment can affect a person's health for months or even years after it has finished. Some side effects may not be evident until years after treatment has ceased. These are called 'late effects'.
Chronic leukemia involves more-mature blood cells. These blood cells replicate or accumulate more slowly and can function normally for a period of time. Some forms of chronic leukemia initially produce no early symptoms and can go unnoticed or undiagnosed for years.
Around 20 out of 100 (around 20 percent) will survive their leukemia for five years or more after diagnosis. Your age affects how well leukemia responds to treatment. Younger people have a better prognosis.
The cause of acute leukaemia is unknown, but factors that put some people at higher risk are: exposure to intense radiation. exposure to certain chemicals, such as benzene. viruses like the Human T-Cell leukaemia virus.
Usually, you'll receive a combination of chemotherapy drugs. Immunotherapy (biologic therapy): This treatment uses certain drugs to boost your body's defense system — your immune system — to fight leukemia. Immunotherapy helps your immune system identify cancer cells and produce more immune cells to fight them.
Acute myeloid leukemia (AML) is the most fatal type of leukemia. The five-year survival rate (how many people will be alive five years after diagnosis) for AML is 29.5%. Leukemia is a cancer that usually affects white blood cells, though it can start in other types of blood cells.
The 5-year survival rate for people age 20 and older is 40%. The 5-year survival rate for people under age 20 is 89%. Recent advances in treatment have significantly lengthened the lives of people with ALL. However, survival rates depend on several factors, including biologic features of the disease and a person's age.
CLL has a very high incidence rate in people older than 60 years. CLL affects men more than women. If the disease has affected the B cells, the person's life expectancy can range from 10 to 20 years.
As leukemia progresses, the frequency of transfusions may increase to two or three times a week. Requiring transfusions more frequently is usually considered a milestone. More frequent transfusions usually are not helpful and the patient is likely to live only a few more days, or a very few weeks at most.
