Facts About Leukemia

Blood CancerOn October 6, 2009 at 1:35 am


Leukemia is a form of cancer affecting the tissues which are responsible for the body’s blood formation that includes the bone marrow and the lymph system. During this condition, there is huge production of the anomalous white blood cells by the bone marrow to such an extent that at times it lends the blood a white cast.

The normally functioning white blood cells are powerful infection-combatants. However, among individuals affected with leukemia the irregular white blood cells have a tendency of accumulating, hindering normal white blood cell production and impeding the body’s capacity to combat infection.

LeukemiaLeukemia treatment is a multifarious approach wherein majority of the patients undergo chemotherapy, while others get treated with radiation therapy, BMT or bone marrow implant or biological therapy. In certain circumstances, surgical excision of the spleen would become part of the treatment approach.

The four key forms of leukemia include:

  • AML or Acute Myeloid Leukemia – Noticed in both grown-ups and in childhood, this form of leukemia is at times known as ANLL or acute non-lymphocytic leukemia.
  • ALL or Acute Lymphoblastic Leukemia – The widely prevalent form of leukemia noted in young children, though also affecting adulthood is inclusive of those in the elderly age bracket of 65 years and above.
  • CML or Chronic Myeloid Leukemia – Though chiefly affecting adults, there are rarely few cases of children also observed with CML.
  • CLL or Chronic Lymphocytic Leukemia – A condition that is mostly known to inflict older aged individuals past 55 years of age. Though at times, it is noted in the younger age bracket adults and rarest ever cited amongst children.

All leukemia forms can be treated with the right approach and majority of them have a potential of being cured.

Leukemia is categorized on the basis of the rate of proliferation, along with the kind of blood cells it is known to affect. The varied leukemia types widely differ according to their nature and gravity and are pigeonholed into either acute or chronic forms.

  • Acute Leukemia – The more belligerent leukemia form that leads to acute symptoms and swiftly progressing to serious medical complications. A dearth of effectual treatment would lead to mortality within time spans of days to weeks.
  • Chronic Leukemia – Progresses at a much slothful pace. Some cases do not need to be treated for months or years.

Leukemias additionally are categorized into myeloid or lymphoid forms on the basis of the kind of the white blood cell (WBC) that has been inflicted. Myeloid cells produce neutrophils – a crucial form of WBC that slaughters bacteria. Lymphoid cells produce lymphocytes that safeguard against bacterial germs inclusive of viruses.

Leukemia has been considered by many as a disease inflicting solely children, though approximately ten times as many grown-ups as children are detected with this form of cancer. Newly surfaced leukemia cases have mounted to roughly thirty thousand cases on an annual basis in the U.S.

Leukemia Signs and Symptoms:

AML or acute myeloid leukemia is a widespread form of acute leukemia that accounts to 80% of such cases, noted amongst adults that affects the primal WBC in the bone marrow. AML has 8 varied sub-categories that differ on the basis of treatment, diagnosis and the form of leukemia cell that is entailed. These comprise of:

  • M0 – Undifferentiated Leukemia – Classified by the excessive production of extremely primal leukemia cells also called blasts, that are undeveloped to such an extent that at times it is tricky to decipher whether they are AML or ALL cells. This leukemia has a poor diagnosis and accounts for lesser than 5% of AML cases.
  • M1 – Acute Myeloblastic Leukemia – This condition accounting for 15-20% of AML cases, is classified by the unwarranted production of very primal WBC or blasts. The bone marrow has in turn, few mature WBC’s.
  • M2 – Acute Myeloblastic Leukemia with Maturation – This condition representing 20-30% of  AML cases is classified by the excess production of the primal WBC’s or blasts wherein the bone marrow comprises of full-grown WBC along with the presence of the blasts. A translocation among the 8th and the 21st chromosomes usually takes place and is suggestive of an improved diagnosis.
  • M3 – Acute Promyelocytic Leukemia or APL – This leukemia form that can be related to acute bleeding, is classified by the occurrence of abnormal promyelocytes in the bone marrow and peripheral blood. A translocation among the 15th and 17th chromosomes commonly takes place and is suggestive of an enhanced diagnosis. This condition accounts for nearly 10-15% of AML cases.
  • M4 -Acute Myelomonocytic Leukemia – This form of leukemia accounting for nearly 20-25% of AML cases is classified by the excessive production of monocytes and myelocytes – the WBC’s that combat contagious agents all over the body.
  • M5 – Acute Monocytic Leukemia – The form of leukemia representing 5-10% of AML cases, is classified by the surfeit production of WBC’s, monocytes and monoblasts that are WBC’s which combat contagious agents all through the body.
  • M6- Acute Erythroblastic Leukemia – This form of leukemia accounting for fewer than 5% of AML cases is classified by the excessive production of primal red blood cells. This leukemia has a poor diagnosis and mostly is noted to evolve from a condition known as myelodysplasia.
  • M7 – Acute Megakaryoblastic Leukemia – Classified by the excess production of primal megakaryocytes that are the cells responsible for giving rise to platelets. This is an atypical form of AML that has an inadequate diagnosis.

Usually the onset of AML is sudden, i.e., in a period of days or weeks. It is not quite often for a patient to be sick for a couple of months. AML causes illness in persons mainly by hindering with the functioning of the normally occurring bone marrow. The offending leukemia cells reinstate and swarm out the normally functioning cells of the bone marrow, thus leading to the sapped blood cell counts. This inadequate number of red blood cells leads to a condition known as anemia that makes an individual feel fatigued and washed out. Dearth if platelets could make one more prone to blood loss and getting bruised, particularly in the skin, nose and gums.

Depleted levels of normal WBC’s raise the chances of infection. Though infections might be of any form, the classical symptoms comprise of:

  • Fever.
  • Experiencing a runny nose.
  • Cough.
  • Discomfort and pain in the chest region or breathing distress and shortened gasps.
  • Pain experienced during urination
  • Occasional diarrhea.

However, highly detrimental are the infections arising in the bloodstream known as sepsis, and pneumonia.
