RESUMO
This study determines the expression of latent membrane protein-1 [LMP- 1] in lymph nodes of patients with classic Hodgkin lymphoma [cHL] and its role in patients' survival. Specimen of 98 patients who had cHL was chosen and the samples were immunohistochemically stained with LMP-1 and Overall disease-free survival [DFS] was measured from the date of complete remission until the Relapse was confirmed by another lymph node biopsy. We investigated the expression of LMP-1 in outcome of patients with cHL. LMP-1 was detected in RS cells of cHL in twenty five out of ninety eight [25.5%] patients. LMP-1 expression was significantly more frequent in mixed cellularity, 46.7%, than nodular sclerosis, 15.4% [P= 0.005]. Patients with EBV-positive tumors had fewer DFS [22.6 vs. 25.9 mo], but the difference was not statistically significant [p=0.06]. Although in our study there is no relationship between age and LMP-1 expression. LMP-1 expression is associated with statistically different DFS in treated patients with cHL
