Polyclonal Antibody Targeting SOX11 Cannot Differentiate Mantle Cell Lymphoma From B-Cell Non-Hodgkin Lymphomas

Nuclear expression of the non B-cell lineage Sox11 transcription factor identifies mantle cell lymphoma.

Mantle cell lymphoma (MCL) is defined pathologically by the detection of CD20, CD5, and most importantly cyclin D1 (CCND1). Its distinction from other lymphomas is important for prognosis and appropriate therapy, but occasional cases may fail to express CCND1 and morphologic simulators may express CD20 and CD5 but not CD23. In this study, we show that the transcription factor Sox11 is specifica...

Radioimmunotherapy for B-cell non-hodgkin lymphomas.

BACKGROUND Radioimmunotherapy (RIT) is a safe and effective therapeutic option for patients with indolent B-cell non-Hodgkin lymphomas (NHL), in both up-front and relapsed/refractory settings. Two approved agents (90Y-ibritumomab tiuxetan and 131I-tositumomab) are available in the United States. Both target CD20 with similar clinical outcomes but with unique clinical considerations and radiatio...

B-cell non-hodgkin lymphoma: targeting in on the future.

SOX11 regulates PAX5 expression and blocks terminal B-cell differentiation in aggressive mantle cell lymphoma.

Mantle cell lymphoma (MCL) is one of the most aggressive lymphoid neoplasms whose pathogenesis is not fully understood. The neural transcription factor SOX11 is overexpressed in most MCL but is not detected in other mature B-cell lymphomas or normal lymphoid cells. The specific expression of SOX11 in MCL suggests that it may be an important element in the development of this tumor, but its pote...

Employing PCR Technique in Assessment of Monoclonality in Large B-cell Non-Hodgkin\'s Lymphoma

Introduction: Most B-cell malignancies are diagnosed based on morphologic and immunohistochemical criteria. Some cases, however, still present a challenge for the pathologist to discriminate between reactive hyperplasia and neoplastic disorders. Molecular techniques can be used as a helpful diagnostic tool in these cases. In this study, we assessed the value of polymerase chain reaction (PCR) t...
