RESUMO
Lymphomas and leukemias, neoplasms of hematopoetic lineage, pose unique challenges that require novel treatment paradigms. The inter-relationship between the immune system and the neoplastic lesion in these diseases dictates that, to evaluate novel therapies, models are needed that mimic human disease in an immunocompetent host. In the present study, we describe a disseminated, syngeneic model of B-cell lymphoma in the Balb/c mouse based upon the A20 cell line. This model mimics aspects of diffuse large B-cell lymphomas in humans, and recapitulates para-spinous tumor growth, bone destruction and nerve root compression, which may complicate disseminated disease. Furthermore, this tumor expresses a key marker of interest, CD40, which is a candidate for tumor-specific vector targeting via current modalities. The present study therefore describes a high-fidelity model of disseminated lymphoma with implications for novel targeted therapeutics.
