The prognostic significance of 20 putative markers has been assessed in a consecutive series of 1,198 patients with malignant lymphoma seen by the Sheffield Lymphoma Group over three decades. Univariate analysis disclosed that ten factors for both Hodgkin's disease (HD) and non-Hodgkin's lymphoma (NHL) Grade I, and twelve factors for NHL Grade II had prognostic significance. However, multivariate analysis selected only three (age, serum albumin and lymphocyte count) for HD, one (serum albumin) for NHL Grade I and five (age, stage, erythrocyte sedimentation rate, serum albumin and serum lactate dehydrogenase) for NHL Grade II as independent predictors for survival. Risk adjusted prognostic models were derived for Hodgkin's disease and NHL Grade II. For Hodgkin's disease the presence of 3 risk factors predicted for only 35% long-term survival for this group of patients. For NHL Grade II the group with 3-5 risk factors present had a median survival of less than 2 years compared to a 9-year median survival in patients with 1 risk factor present. Whilst these models are being validated on a larger series of patients and will also be tested prospectively, new markers are needed to facilitate decisions on treatment for individual patients.
