Project description:Peripheral T-cell Lymphoma cases along with normal T-cells were subjected to gene expression profiling by means of a DASL array. The cases included both PTCL/NOS and Lennert Lymphoma.
Project description:We performed gene expression profiling in 34 peripheral T-cell lymphoma, including 7 cases of gamma delta T-cell lymphoma to identify a unique T-cell receptor signature gene set for classification of gamma delta T-cell lymphoma and alpha beta T-cell lymphoma.
Project description:This phase I trial studies the side effects and the best dose of alisertib when given together with vorinostat in treating patients with Hodgkin lymphoma, B-cell non-Hodgkin lymphoma, or peripheral T-cell lymphoma that has come back. Alisertib and vorinostat may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth.
Project description:The distinction between the Burkitt lymphoma and diffuse large B-cell lymphoma is imprecise using current diagnostic criteria. We applied transcriptional and genomic profiling to molecularly define Burkitt lymphoma. Gene expression profiling employing Affymetrix GeneChips (U133A) was performed in 220 mature aggressive B-cell lymphomas, including a core group of eight Burkitt lymphomas, which fulfilled all diagnostic criteria of the WHO classification. A molecular signature of Burkitt lymphoma was generated. Chromosomal abnormalities were detected by interphase fluorescence in-situ hybridization and array comparative genomic hybridization. The molecular Burkitt lymphoma signature identified 44 cases. Fifteen of these cases lacked a morphology typical for Burkitt/Burkitt-like lymphoma. The vast majority (88%) of the 176 lymphomas without the molecular Burkitt lymphoma signature represented diffuse large B-cell lymphomas. In 20% of these cases a MYC break was detectable which was associated with complex chromosomal changes. Our molecular definition of Burkitt lymphoma sharpens and extends the spectrum of Burkitt lymphoma. In mature aggressive B-cell lymphomas without a Burkitt lymphoma signature, a chromosomal break in the MYC locus proved to be associated with adverse clinical outcome. Keywords: Gene expression
