Abstract Abstract 4633 Background: Golgins are proteins of the Golgi complex. Several Golgins have been implicated in apoptosis. Expression of Golgin-84, a Golgin protein, is altered in apoptotic WEHI-231, a B-cell lymphoma line, suggesting that Golgin-84 may play a role in lymphoid tumorigenesis. Here, we aimed to determine the expression levels of Golgin-84 in human primary non-Hodgkin lymphomas and plasma cell myeloma. Design: Golgin-84 expression was investigated in non-Hodgkin lymphoma cell lines by using Western blot analysis and polyclonal antibodies. Using immunohistochemical stains, Western blotting analysis and Q-PCR, Golgin-84 expression was assessed in 5 reactive lymph nodes, 149 cases of primary non-Hodgkin lymphoma and 28 cases of primary plasma cell myeloma. Results: Immunohistochemical stains, Western blotting analysis and Q-PCR on 5 reactive lymph nodes demonstrated that Golgin-84 was expressed at low levels in lymphoid cells of germinal centers, mantle cells, marginal zones, and interfollicular areas. Golgin-84 was variably expressed in non-Hodgkin lymphoma cell lines tested, with the highest levels in cells from high-grade tumors (e.g. anaplastic large cell lymphoma; ALCL, Diffuse large B-cell lymphoma (DLBCL), ALCL and peripheral T-cell lymphoma unspecified (PTCL)) and the lowest levels in mantle cell lymphoma (MCL) cells. DLBCL, ALCL and PTCL frequently showed high expression of Golgin-84. Most lymphoplasmacytic lymphomas (LPL) and plasma cell myeloma (PCM) expressed high levels of Golgin-84. Expression levels of Golgin-84 were lower in MCL and low-grade B-cell non-Hodgkin lymphomas, including chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL), follicular lymphoma (FL), and marginal zone lymphoma (MZL). Conclusions: Golgin-84 expression levels are low in lymphoid cells of normal lymph nodes. Most (>90%) cases of LPL and PCM, and at least half of cases of DLBCL, ALCL and PTCL express high levels of Golgin-84. These findings suggest that Golgin-84 may be involved in tumorigenesis or lymphoma progression, particularly in neoplasms with plasmacytic differentiation. Disclosures: No relevant conflicts of interest to declare.

Background/Aim. Bronchus-associated lymphoid tissue (BALT) lymphoma is a rare subtype of low grade marginal zone B cell lymphoma representing 10% of all MALT lymphomas. The purpose of this study was to analyze the outcome of this group of patients comparing prognostic parameters and therapy modalities. Methods. A total of eight patients with BALT lymphoma had diagnosed between January 1998 - April 2008 at the Institute of Hematology, Clinical Center of Serbia, Belgrade, and they were included in this retrospective analysis. Results. Male/female ratio was 2/6, the median age was 64 years (range 37-67 years). Six patients had nonspecific respiratory symptoms and all of them had B symptoms. The patients were seronegative for HIV, HCV and HBsAg. Three patients had Sjogren's syndrome, rheumatoid arthritis and pulmonary tuberculosis, respectively. Seven patients were diagnosed by transbronchial biopsy and an open lung biopsy was done in one patient. Patohistological findings revealed lymphoma of marginal zone B cell lymphoma: CD20+/CD10-/CD5-/CyclinD1- /CD23-/IgM- with Ki-67+<20% of all cells. According to the Ferraro staging system, five patients had localized disease (CS I-IIE) and three had stage IVE; bulky tumor mass had 3 patients. All patients had Eastern Cooperative Oncology Group (ECOG) performance status (PS) 0 or 1. Five patients received monochemotherapy with chlorambucil and 3 were treated with CHOP regimen (cyclophosphamide, doxorubicin, vincristine and prednisone). A complete response (CR) was achieved in 5 patients and a partial response (PR) in 3 of them, treated with chlorambucil monotherapy and CHOP regimen. All patients were alive during a median follow-up period of 49 months (range 6- 110 months). Three patients relapsed after monochemotherapy into the other extranodal localization. They were treated with CHOP regimen and remained in stable PR. Conclusion. BALT lymphoma tends to be localised disease at the time of diagnosis, responds well to monochemotherapy with chlorambucil and has a favourable prognosis.
