Stage 4 lymphoma is not always terminal, according to Healthline. The survival rate for stage 4 Hodgkin lymphoma is 65 percent at the five-year mark. The survival rate for stage 4 non-Hodgkin lymphoma depends on the type of the lymphoma and the patient’s age and lactate dehydrogenase blood level.
There is a differentiation between stage 4 Hodgkin lymphoma and stage 4 non-Hodgkin lymphoma, according to Healthline. Stage 4 Hodgkin lymphoma affects the lymph nodes below and above the diaphragm, and cancer cells are present in the bone, liver, lung or other regions of the body. Non-Hodgkin lymphoma at stage 4 spreads to organs beyond the lymph nodes and sometimes to more lymph node locations.
The International Prognostic Index is used to help doctors provide a fairly accurate prognosis for lymphoma patients, according to the American Cancer Society. The index uses five factors in determining a patient’s outlook, including the patient’s age, the stage of the lymphoma and its location, blood serum levels of LDH, and the patient’s ability to complete normal activities of daily living.
Around 79,990 new cases of lymphoma were projected to occur in the United States in 2014, according to the Leukemia and Lymphoma Society; most of those were expected to be non-Hodgkin lymphoma. Around 731,277 people were living with lymphoma in the United States during the same time period.
