Prognostic parameters in low-grade non-Hodgkin's lymphomas.

In a group of 73 patients with low-grade non-Hodgkin's lymphomas (LG NHL) a multivariate analysis of the following variables was performed: pathological types following the International Working Formulation, clinical stage, B-symptoms, erythrocyte sedimentation rate, hemoglobin level, white blood cell and lymphocyte count, serum gamma globulin level, serum total lactic dehydrogenase (LDH) level, mitotic and complete remission. The patients with lymphocytic lymphoma manifested the best survival in this group. Low-proliferative lymphomas showed better survival than high-proliferative lymphomas at 3 and 10 years. B-symptoms, serum total LDH level and complete remission were significant independent prognostic factors.
