Burkitts Lymphoma

By Jonathyn David

Burkitts lymphoma is an exceedingly rare type of cancer. Less than a thousand cases are diagnosed yearly in the United States of America.

However, in some other parts of the world where it is endemic, such as certain parts of central Africa, Burkitt’s lymphoma is very common among children.

Burkitt’s lymphoma is a Non-Hodgkin’s Lymphoma (NHL) cancer that affects B lymphocyte cells. There are 3 distinct varieties of this disease:

-Immunodeficiency-related: This form of the condition occurs most often in HIV patients and similarly immunocompromised individuals such as recent transplant recipients. The condition may signal the onset of AIDS.

-Sporadic: This variant of the disease is found outside of the African continent. It is akin to endemic Burkitt’s lymphoma and is associated with immune system compromise.

-Endemic: This form of the disease is the so-called “African” form and is responsible for the majority of malignant cases in central African children. This form of the disease may affect several areas but most often impacts the jaw, ovaries, breasts, kidneys, facial bone. The Epstein-Barr virus, which is the virus responsible for mononucleosis is closely associated with Burkitt’s.

The symptoms of Burkitts lymphoma may include painless, swollen lymph nodes (this is characteristic of lymphomas in general), hardening and/or rapid growth of the lymph nodes. Pain in the abdomen is another possible sign.

This disease can be diagnosed by a variety of modes such as:

-X-ray of the chest
-Blood Count
-Spinal fluid analysis
-Lymph node and/or bone marrow biopsy
-CT and/or PET scan

Treatment of this disease usually involves intense chemotherapy. The earlier that chemotherapy is started, the better the outlook as this is a particularly aggressive form of cancer. However, some cancers which grow rapidly such as Burkitt’s, respond more quickly to treatment. This can actually harm the patient through a process called tumor lysis syndrome, in which the body is subjected to the byproducts of the breakdown of cancer cells which may cause any of a host of serious complications such as severe electrolyte disruption and renal failure.

Combination chemotherapy may be supplemented with radiotherapy, dietary interventions, nootropics, supplements, exposure to natural sunlight (for vitamin D). Surgery is often indicated for the removal of tumors and a bone marrow transplant may be necessary in the case that the bone marrow is affected.

The prognosis of Burkitt’s lymphoma depends upon the risk-factor of the patient. Caught early (low-risk or low/intermediate risk), combination chemotherapy which has produced survival rates in the 90% range. These figures decline significantly for higher risk cases; ~70% for high/intermediate risk and ~30% for high risk. The total 5 year survival rate for adults with Burkitts lymphoma is about 50 percent.

Treatment Of Acute Myeloid Leukemia – Hanging On To Life

By Dave Morrison

Acute myeloid leukemia is a heterogeneous cancer of the blood and bone marrow. This tumor occurs as a result of an over production of immature white blood cell which is called myeloblast.

The name of the disease is gotten from the blood cell produced in excess. The immature white blood cell produced gets into the bone marrow and it’s over production hinders the production of the normal blood cells.

The main cause of the display of these symptoms is as a result of the loss of normal function of blood by these myelobast. Since they are immature and reduce the mature and proper functioning blood, their function as blood cells is greatly reduced. One of the functions of blood affected in acute myeloid leukemia is fighting against infection.

Patients with acute myeloid leukemia are easily infected due to reduced immunity against infection. Another very common symptom in patients suffering from acute myeloid leukemia is anemia. Anemia is as a result of reduced production of normal red blood cells and platelets. Anemia is usually severe with different levels of severity seen in different patients. Acute myeloid leukemia has other symptoms like being easily bruised and having swollen gum, bleeding of the nose, fever, skin pallor and even shortness of breath.

The treatment of acute myeloid leukemia in a newly diagnosed patient consist of chemotherapy ( the type of chemotherapy used is age dependent) aimed to quickly induce total remission, when this is achieved, further therapy is then aimed at cure of the disease (by eliminating any undetected residuals of the leukemic cells). Therefore the treatment process is divided into two stages.

The first stage is the stage of induction. The goal of this therapy is to get complete remission by reducing the quantity of the leukemic cells in the bone marrow and circulating blood to an undetectable level. The commonly used complete remission induction is a combined chemotherapy of cytarabine and anthracycline. Cytarabine is administered intravenously with dosage of 100 – 200mg/m2/day for one week. Anthracycline consists of daunorubicin is administered intravenously 45-60mg/m2 on day1, 2, and 3.

When induction therapy is completed, the bone marrow is examined. If blast cells are more than 5% with up to 20% cellular cells, induction therapy is performed again with dose similar to the first but cytarabine is given for 5 and antracycline 2 days. But after the second therapy if there is no positive result stem cell transplant is considered, though this is only possible in patient younger than 65 years.

The second stage is post remission or consolidation therapy, which is aimed at cure of patients with acute myeloid leukemia after the leukemic cells becomes undetectable. In this therapy treatment is based on the patient’s condition, this therapy involves an additional intensive chemotherapy of 3 to 5 courses. Patients with high risk of cytogenetics are given allogeneic stem cell transplant. Patients who stem cell transplant is not suitable for, are treated with a combination therapy of histamine dihydrochloride (ceplene) and interleukin 2.

The treatment of acute myeloid leukemia has shown good prognosis in the time past especially if diagnosis is made early ant treatment is started immediately.
