Abstract
BACKGROUND
The expression of neuropilin-1 (NRP-1) in Epstein-Barr virus (EBV)-associated lymphomas and its relationships with clinicopathological parameters was investigated.
METHODS
The researchers compared 111 cases of patients with lymphoma to 20 cases of reactive lymphoid hyperplasia. In situ hybridization was applied to observe the expression of EBV-encoded RNA (EBER) in lymphomas, and immunohistochemistry was used to detect the NRP-1 expression in lymphoma tissues and lymph node tissues with reactive hyperplasia.
RESULTS
In these 111 cases, the EBER of 62 cases (55.9%) appeared positive. NRP-1 was relatively highly expressed in lymphomas (P= 0.019). Further, NRP-1 showed higher expression in lymphomas with positive EBER than in negative ones. A comprehensive analysis revealed that NRP-1 was differently expressed in NK/T-cell lymphoma, Hodgkin's lymphoma, diffuse large B-cell lymphoma, and anaplastic large cell lymphoma (P= 0.027). Moreover, highly expressed NRP-1 was found to be a useful independent prognostic factor in assessing overall survival and progression-free survival rates in cases of non-Hodgkin's lymphoma (NHL).
CONCLUSIONS
NRP-1 exhibited higher expression in lymphomas, and it was positively expressed in EBV-positive lymphomas. Moreover, highly expressed NRP-1 can be used as an undesirable independent prognostic factor in NHL.
