Diffuse large cell lymphoma. Prognostic factors with treatment
Antineoplastic Combined Chemotherapy Protocols
Lymphoma, Large B-Cell, Diffuse
Five successive chemotherapy protocols for stages II, III and IV diffuse large cell lymphoma (DLCL) have resulted in identical overall survivals. Between 35% to 45% of patients survived. In a multivariate analysis employing the Weibull model 3 factors were associated with shortened survival: bulky mediastinal and/or retroperitoneal disease, elevated serum LDH and advanced age. In young patients with bulky mediastinal and/or retroperitoneal disease and high serum LDH, autologous bone marrow transplantation following high dose chemotherapy and radiation therapy (RT) as part of the initial treatment have produced more promising results. In a randomized trial, a significantly longer disease-free survival was found for patients with stages I or IE diffuse lymphomas with RT followed by adjuvant chemotherapy than with RT alone.
