[Clinical Significance of Detecting CyclinD1 and BCL-2 in Patients with B-Cell Lymphoma by Using Flow Cytometry]

To explore the feasibility and value of detecting CyclinD1 and BCL-2 in patients with B-cell lymphoma by using flow cytometry.

Fifty-three patients with lymphoma were selected, and 50 healthy persons in the same period were selected as control. The expression levels of CyclinD1 and BCL-2 in patients with various subtypes of lymphoma were detected by using flow cytometry (FCM).

When the dilution time was 1 min and the dilution proportion was 1:20, the cell morphology was the best complete, at the 4 min the cell morphology was best status. The mean fluorescence intensity of CyclinD1 and BCL-2 between persons of control group and patients with B-cell lymphoma showed significant difference, the CyclinD1 level (1.824 ± 0.315) and BCL-2 levels (4.257 ± 0.528) of patients with B-cell lymphoma were obviously higher than the CyclinD1 level (0.634 ± 0.153) and BCL-2 level (1.926 ± 0.328) of persons in control group, the CyclinD1 and BCL-2 expression levels of patients with HL were significantly lower than CyclinD1 and BCL-2 levels of patients with NHL (P < 0.01). After treatment, the expression levels of CyclinD1 and BCL-2 in patients with B lymphoma were significantly lower than these befor treatment.

Using the method of flow cytometry for detecting CyclinD1 and BCL-2 expression levels in lymphoma cells of patients is feasible, and it can be applied clinically to evaluate the treatment efficacy.
