Firstly, increased Ki67 and MUM-1 staining has been associated with worse prognosis in marginal zone B cell lymphomas (MZL). However, ours is the first study to assess the impact of proliferative indices on chemotherapy response. Secondly, loss of p53 and p16 tumor suppressor genes (TSG) has traditionally been associated with cancer progression. The(More)
AIM To report the first case of a Richter syndrome where small lymphocytic lymphoma (SLL) progressed to a CD3+ diffuse large B-cell lymphoma (DLBCL). METHODS Macrodissection of small and large cell lymphomatous components was performed. This was followed by flow cytometric analysis along with molecular B-cell immunoglobulin (heavy and light chains) and(More)
CD4 expression is rare in diffuse large B-cell lymphoma (DLBCL), with 4 previously reported cases. Its significance is uncertain. We report five patients with CD4(+) DLBCL and one CD4(+) primary mediastinal large B-cell lymphoma. Cases were identified by searching the electronic database of the department; each was reviewed. Average age was 56 years.(More)
BACKGROUND Recent studies have shown dismal outcomes when chronic lymphocytic leukemia progresses to Richter syndrome after patients receive ibrutinib, with a median overall survival ranging from 2.6 to 3.5 months. Published data on efficacy of allogeneic hematopoietic cell transplantation in Richter syndrome are limited to single-center case series and(More)
Although several technologies can be used to detect gene fusions, anchored multiplex PCR next-generation sequencing (AMP-NGS) offers the advantage of novel fusion detection and the ability to multiplex multitudinous genes. We applied AMP-NGS technology in the evaluation of a 56-year-old gentleman with myelodysplastic syndrome transformed acute myeloid(More)
Myeloid/lymphoid neoplasms with FGFR1 rearrangement are a rare entity. We present a multicenter experience of 17 patients with FISH-confirmed FGFR1 rearrangement. The clinical presentation at diagnosis included myeloproliferative neoplasm (MPN) in 4 (24%) patients, acute leukemia (AL) in 7 (41%), and concomitant MPN with AL in 6 (35%). The two most(More)
PRDM1 (BLIMP1) is a transcription repressor protein shown to be involved in B-cell differentiation into plasma cells. Marginal zone lymphomas (MZL) and lymphoplasmacytic lymphomas (LPL) are B cell lymphomas that both show some degree of plasmacytic differentiation and thus can sometimes constitute a difficult differential diagnosis. In this study, we(More)
Objectives To compare the mutational profiles of patients with primary myelofibrosis (PMF), polycythemia vera (PV), and essential thrombocytosis (ET). Methods Next-generation sequencing results of 75 cases of PMF, 33 cases of PV, and 27 cases of ET were compared. Results Mutation rates of ASXL1 and SRSF2 were significantly higher in PMF than in PV or(More)
