The presence of the Bcl-2/IgH fusion gene was detected in BM samples and paraffin-embedded lymph node (LN) samples from 103 patients with DLBCLs using FISH.     ///    "During the follow-up, no infiltration by cytomorphology for 16 DLBCL patients whose bone marrow presented Bcl-2/IgH gene rearrangement at diagnosis, and two cases were positive by morphology compared to FISH-positive results 6 months later. "    ///    "Utilizing both FISH and cytologic morphology, the assessment of Bcl-2/IgH translocation status could contribute to the better detection of minimal bone marrow infiltration and relapse receiving treatment by DLBCL cells.. "    ///    Bcl-2/IgH translocation in paraffin-embedded LN tissue sections was observed in 43 (41.7%) patients by FISH.     ///    "Of the 43 patients, the Bcl-2/IgH rearrangement in the bone marrow specimens occurred in 34 patients. "    ///    Bcl-2/IgH expression of diffuse large B-cell lymphoma cells in minimal bone marrow infiltration..     ///    "The Bcl-2/IgH recombination rate in stage III cancers was not significantly different compared to the rate observed in stage I/II cancers (p = 0.101), respectively showing no statistical differences between stage IV and I/II (p = 0.179). "    ///    9 out of 16 patients (56.3%) presented with positive Bcl-2/IgH results earlier than the morphology evaluation after 12 months.
