Five-year survival rate is 65% in the United States. [4] In children under 15 in first-world countries, the five-year survival rate is greater than 60% or even 90%, depending on the type of leukemia. [13] In children with acute leukemia who are cancer-free after five years, the cancer is unlikely to return.
Treatment. Watchful waiting, chemotherapy, immunotherapy [4] [5] Prognosis. Five-year survival ~88% (US) [3] Frequency. 904,000 (2015) [6] Deaths. 60,700 (2015) [7] Chronic lymphocytic leukemia ( CLL) is a type of cancer in which the bone marrow makes too many lymphocytes (a type of white blood cell ).
Person with t(9,22) positive-ALL (30% of adult ALL cases) and other Bcr-abl-rearranged leukemias are more likely to have a poor prognosis, but survival rates may rise with treatment consisting of chemotherapy and Bcr-abl tyrosine kinase inhibitors.
Acute erythroid leukemia (M6) has a relatively poor prognosis. A 2010 study of 124 patients found a median overall survival of 8 months. A 2009 study on 91 patients found a median overall survival for erythroleukemia patients of 36 weeks, with no statistically significant difference to other AML patients.
In the United States between 2011 and 2016, the median survival of a person with AML was 8.5 months, with the 5 year survival being 24%. This declines with age, with the poorer prognosis being associated with an age greater than 65 years, and the poorest prognosis seen in those aged 75–84.
The prognosis of adult-AMKL in patients treated for the disease is far below that of other forms of AMKL. Their median overall survival times are only 18 to 41 weeks with 5 year survival rates of only 10-11 percent. Major improvements in these statistics will likely require new approaches directed at the underlying mechanisms driving the disease.
Prognosis Factors affecting prognosis. CMML-2 has a reduced overall survival as compared with CMML-1, with median survivals of 15 and 20 months, respectively. Myeloproliferative CMML (>13x10 9 monocytes/L) has a reduced survival compared with myelodysplastic CMML. A platelet count of <100 x10 9 /L reduces overall survival. A haemoglobin level ...
About 1-10% of CLL/SLLs develop a Richter's transformation at a rate of 0.5–1% per year. In earlier studies, the transformed disease was reported to be far more aggressive than CLL/SLL with overall median survival times (i.e. times in which 50% of cases remain alive) between 1.1 and 16.3 months.
Prognosis. The 5 year survival has been noted as 89% in at least one study from France of 201 patients with T-LGL leukemia. Epidemiology. T-LGLL is a rare form of leukemia, comprising 2-3% of all cases of chronic lymphoproliferative disorders. [citation needed] History
A 2006 follow-up of 553 patients using imatinib (Gleevec) found an overall survival rate of 89% after five years. A 2011 followup of 832 patients using imatinib who achieved a stable cytogenetic response found an overall survival rate of 95.2% after 8 years, which is similar to the rate in the general population.
