The Gene Expression Study (GEP) was based on a cohort of 27 MCL cases enrolled in the Fondazione Italiana Linfomi (FIL)-MCL-0208 randomized Italian clinical trial.

The aggressive clinical behavior of mantle cell lymphoma (MCL) is attributed to specific genetic and molecular mechanisms involved in its pathogenesis, mainly the t(11;14)(q13;q32) traslocation and cyclin D1 (CCND1) overexpression. Nevertheless, evidence of a certain degree of clinical/biological heterogeneity has been disclosed by gene expression profile (GEP) and (immuno)genetic/immunohistochemistry studies. AIM: To use a GEP approach to identify MCL subsets with peculiar clinical/biological features in the context of of MCL patients treated homogeneously with an autologous transplantation-based program. GEP experiments were performed in 27 cases, with Agilent platform. Bioinformatics analyses were performed by Gene Springs
