pubmed:abstractText |
The genomic profile of mantle cell lymphoma (MCL) has been reported to be significantly different from that of other indolent lymphoproliferative disorders, Topoisomerase IIalpha, glutathione-s-transferasepi (GSTpi) and ABCG2 (BCRP) chemoresistance genes being over-expressed in MCL. In our study, expression levels of the above mentioned genes plus MDR1 were tested on bone marrow samples from 20 patients treated with Rituximab plus hyper-CVAD regimen, in order to evaluate a possible impact of the chemoresistance phenomenon on this promising treatment regimen. All patients expressed ABCG2 and MDR1 genes; 85% of cases expressed GSTpi and topoisomerase IIalpha. Only ABCG2 were over-expressed in comparison both with marrow from healthy donors and tonsilar CD5+/CD20+ lymphocytes (adopted as normal counterpart of the neoplastic population). The overall response rate of the entire series was 87.5%, with 44% of complete responses. Fifty-seven percent of patients achieved the clearance of minimal residual disease. Levels of tested genes did not condition either quality of clinical response or PFS (76% at 24 months). Nevertheless, an ABCG2 higher expression appeared associated with a worse PFS and levels of this gene paralleled the status of minimal residual disease. A further evaluation of ABCG2 expression in larger series of MCL patients would be suitable.
