what is the true mortality rate of burkits lymphoma?

Burkitt's lymphoma is a rare and aggressive form of Non-Hodgkin's lymphoma. This makes it very life-threatening, but also makes it very sensitive to chemotherapy and therefore potentially curable.

I assume you're talking about adults.

"The prognosis for adults depends on a number of factors. In recent years, the International Prognostic Index, or IPI, has been used to predict a specific patient's chance of recurrence and length of survival on the basis of five factors. Each of the following factors is given one point:

* age over 60 years

* the lymphoma is classified as Stage III or Stage IV

* the lymphoma has spread to more than one site outside the lymph nodes

* high levels of lactate dehydrogenase (an enzyme used to measure tumor burden)

* poor general health

An IPI score of 0 or 1 is associated with a 70% rate of disease-free survival at the end of five years and an overall survival rate of 73% at the end of five years. An IPI score of 5, on the other hand, is associated with five-year rates of 40% disease-free survival and 26% overall survival respectively."
