Background and methods: The diffuse large cell non-Hodgkin lymphomas are a heterogeneous group of neoplasms that are potentially curable. To identify important predictors of clinical outcome, the authors evaluated the clinical and pathologic features of 114 patients with newly diagnosed diffuse large B-cell lymphoma who were uniformly staged and treated with curative intent. The authors were particularly interested in determining whether any pathologic features added to the ability of the clinical features to predict patient survival.
Results: Several clinical and pathologic features were found to be associated with survival by univariate analysis. However, multivariate analysis disclosed that only the stage of disease and the symptom status were significantly associated with survival. Low stage and lack of B symptoms were favorable indicators of overall survival and failure-free survival.
Conclusions: The authors suggest that the evaluation of pathologic features in diffuse large B-cell lymphoma has little prognostic utility and recommend that the pathology evaluation be limited to features that are useful for diagnostic purposes.
