Abstract:
Objective To investigate the expressions and significance of PAX-5, OCT-2 and BOB.1 in Hodgkin lymphoma (HL). Methods Immunohistochemical method was used to detect the expressions of CD30, CD15, PAX-5, OCT-2, BOB.1, CD20 and CD3 in 44 samples of formalin-fixed, paraffin-embedded tissues of HL. The histological classification was carried out according to the WHO classification for tumors of hematopoietic and lymphoid tissues (2001). Results In all 44 cases, 3 (6.8) were nodular lymphocyte predominant Hodgkin lymphoma (NLPHL) and 41 (93.2) were classical Hodgkin lymphoma (CHL). In Hodgkin and Reed Sternberg cells, CD30 were expressed in 36 samples (81.8), CD15 in 27 (61.4), CD20 in 14 (31.8), PAX-5 in 43 (97.7), OCT-2 in 14 (31.8), and BOB.1 in 7 (15.9). All samples of NLPHL expressed OCT-2 and BOB.1, while in the samples of CHL, 30 samples (73.2) expressed both OCT-2 and BOB.1, 7 (17.1) expressed only OCT-2, 1 (2.4) expressed only BOB.1 and all were negative for CD30. Conclusion Hodgkin lymphoma is a rare neoplasm with uncertain cause and difficult to diagnose. The detection of PAX-5, OCT-2 , BOB.1 in combination with CD30, CD15 will conduce to the diagnosis and differential diagnosis of Hodgkin lymphoma.
