Study Description
Brief Summary:
The investigators perform a retrospective microarray gene expression profiling study of FFPE from a cohort of DLBCL patients with whole genome cDNA mediated Annealing Selection and Ligation (WG-DASL) assay. The investigators also study the pattern of microRNA from patients with diffuse large B-cell lymphoma. The results of gene expression profiles and microRNA is correlated with clinical outcomes of diffuse large B-cell lymphoma.

Condition or disease
Diffuse Large B-cell Lymphoma

Detailed Description:
  1. Whole genome cDNA mediated Annealing Selection and Ligation (WG-DASL) assay

  2. Nano string assay for microRNA

    • Diffuse large B-cell lymphoma patients
    • Paraffin-embedded tissue
    • End points: Progression-free survival, overall survival
    • Statistics: Leave one-out method
