title: Value of the determination of TNF-alpha in the plasma of patients with non-Hodgkins lymphoma.
abstract: The present report describes the value of the plasma determination of TNF-alpha, at diagnosis, in 43 patients with non-Hodgkin's lymphoma (NHL), related to their clinical presentation and the new International Prognosis Index (IPI). We also compare the levels of TNF-alpha with those of LDH, beta-2-microglobulin (beta-2-m), and ferritin. At diagnosis, the mean values of the quotients between the marker values and the maximum value of normal (ratio:r-) are placed 7 times higher than normal for r-TNF-alpha, whereas those of r-beta-2-m and r-LDH are 2,4 and 1,4 times more respectively. We found a relationship between the value of r-TNF-alpha and the ECOG, Ann Arbor stage, the number of affected extranodal sites, and between the values of r-beta-2-m with r-LDH. The best correlation was obtained between the values of r-TNF-alpha and r-beta-2-m and IPI, however r-TNF-alpha best stratify the four risk groups in this prognosis index.
