Abstract

OBJECTIVE: Mantle cell lymphoma (MCL) is a non-Hodgkin lymphoma (NHL) featured by participation of the lymph nodes, spleen, blood and bone marrow with a short remission period to standard therapies and a median overall survival of 4-5 years. PATIENTS AND METHODS: In this study, we compare the levels of bcl-1/JH fusion products detected by q-PCR in the concurrent peripheral blood (PB) and bone marrow (BM) aspirate samples from 7 patients with MCL. RESULTS: In patients with moderate to high levels of bcl-1/JH copies, the results of q-PCR analysis of PB and BM aspirate samples correlate well. In patients with high levels of bcl-1/JH copies, instead, PB levels are a good indication of tumor burden. Finally, in patients with low levels of bcl-1/JH copies, the t(11;14) may be detected by identification of neoplastic cells. CONCLUSIONS: Our data suggest that PB can be reliably used in place of BM aspirate both for detection of translocation status during minimal residual disease monitoring and for a possible molecular relapse, especially in those patients who have moderate to high levels of bcl-1/JH copies. If these results will be confirmed on a wider number of MCL patients, future study will be required to address the issue.
