The five-year relative survival rate for B-cell lymphoma is 67 percent, while the 10-year relative survival rate is 55 percent, according to the University of Maryland Medical Center. Aggressive B-cell lymphomas are often curable, while slow-growing lymphomas are difficult to treat and often recur after remission. Actual survival rates for B-cell lymphoma depend on the stage of the condition and age of the patient.
B-cell lymphomas, a form of non-Hodgkin’s lymphoma, develop in the lymphatic system and mostly affect people in their 60s and 70s, notes the University of Maryland Medical Center. After diagnosis, 67 percent of patients survive through the first five years while 55 percent of patients survive 10 years. Patients with slow-growing B-cell lymphoma are at a high risk of disease-specific death than those with aggressive lymphoma. Slow-growing lymphomas are potentially curable if diagnosed in the first or second stage. However, since they do not produce any symptoms until they reach advanced stages, indolent lymphomas spread to other sites and become difficult to treat.
Although aggressive lymphomas are often curable, they are more likely to cause early death if left untreated, states the University of Maryland Medical Center. High-grade aggressive B-cell lymphomas are curable with intensive chemotherapy combinations. Since the early 1990s, survival rates for lymphoma patients, especially those under the age of 45, have significantly improved.
