We present a cohort of 22 patients with type 2 dendritic cell (DC2) acute leukemia (or blastic plasmacytoid dendritic cell neoplasm-BPDCN, as it has been recently named), diagnosed in Greece over the past 12-year period, according to the main clinical and immunophenotypic features of this entity. Four additional cases are discussed, classified as leukemia(More)
Splenectomy has traditionally been considered as a standard first line treatment for splenic marginal zone lymphoma (SMZL) conferring a survival advantage over chemotherapy. However it carries significant complications, especially in elderly patients. The purpose of this retrospective study was to report our experience on the efficacy of Rituximab as first(More)
BACKGROUND AND OBJECTIVES Interleukin-10 (IL-10) is a pleiotropic cytokine which increases bcl-2 levels and protects cells from steroid or doxorubicin-induced apoptosis. Hodgkin and Reed-Sternberg (HRS) cells bear functional IL-10 receptors. Thus serum IL-10 (sIL-10) might inhibit apoptosis in HRS cells, which could occur as a result of either chemotherapy(More)
Primary cutaneous marginal zone lymphoma (PCMZL) is an indolent disease. Treatment options include excision, local irradiation, interferon-alpha or chemotherapy. We present two patients with PCMZL and multiple skin lesions successfully treated with intralesional administration of the anti-CD20 monoclonal antibody rituximab. The first presented with four red(More)
Pulmonary involvement in Waldenström's macroglobulinaemia (WM) occurs in 3-5% of cases, but lung involvement without bone marrow infiltration is extremely rare. We report 2 patients who presented with bilateral consolidations on chest X-ray and non-specific symptoms and were treated for a long period of time for pulmonary infections until the diagnosis was(More)
AIMS To evaluate the independent prognostic value of apoptotic versus proliferative fractions in a series of 92 patients with non-Hodgkin's lymphomas (NHL). METHODS AND RESULTS Apoptotic fractions were quantified by use of the TdT (terminal deoxynucleotidyl-transferase)-mediated in-situ end-labelling technique (TUNEL), the percentage of positive cells(More)
We investigated the prognostic value of proliferating cell nuclear antigen (PCNA) and p53 oncoprotein expression and of nucleolar organiser region (NOR) scoring, in relation to classic clinicopathological parameters, in a series of non-Hodgkin's lymphomas (NHL). Paraffin embedded tissue from 91 patients with NHL was stained immunohistochemically with the(More)
BACKGROUND Syndecan-1 (CD138) is expressed by the Hodgkin-Reed-Sternberg (HRS) cells of classic Hodgkin's lymphoma (cHL), but not in nodular lymphocyte-predominant HL. Syndecan-1 may be involved in the interaction between HRS cells and the cellular and stromal microenvironment typical of nodular sclerosing HL. PATIENTS AND METHODS Serum levels of soluble(More)
BACKGROUND AND OBJECTIVES Serum beta(2)-microglobulin (s beta(2)m) is an established prognostic factor for multiple myeloma and non-Hodgkin's lymphoma, but only limited data suggest an adverse prognostic significance for Hodgkin's lymphoma (HL). This study was undertaken to examine the impact of s beta(2)m on the prognosis of patients with HL. DESIGN AND(More)
To evaluate the efficacy of EBVD combination chemotherapy followed by low dose (LD) involved field (IF) radiation therapy (RT) in patients with clinical stage (CS) I-IIA Hodgkin's disease (HD), we analyzed 148 patients treated in our Unit from March 1988 to November 1995. EBVD consisted of Epirubicine 40 mg/m2, Bleomycin 10 mg/m2, Vinblastine 6 mg/m2 and(More)
