Survival rates vary widely between different types of non-Hodgkin’s lymphoma and can usually be initially determined based on whether a patient has high-risk factors that affect prognosis, which include.
Age over 60 years; stage III or IV tumour; more than one site of extra-lymph node invasion; need for bed or someone else’s care; and significantly elevated serum LDH.
The prognosis is divided into four classes based on the high-risk factors the patient has.
Low risk: Patients with 0 to 1 high-risk factor have a 2-year survival rate of 84% and a 5-year survival rate of 73%.
Low-intermediate risk: patients with 2 high-risk factors have a 2-year survival rate of 66% and a 5-year survival rate of 50%.
High to medium risk: Patients with 3 high risk factors have a 2 year survival rate of 54% and a 5 year survival rate of 43%. High risk: patients with 4-5 high-risk factors have a 2-year survival rate of 34% and a 5-year survival rate of 26%.
