ABSTRACT
<p><b>OBJECTIVE</b>To investigate the feasibility of detecting cyclin D1 protein expression and t(11;14) chromosomal translocation in paraffin-embedded tissues and its diagnostic and differential diagnostic significance for mantle cell lymphoma (MCL).</p><p><b>METHODS</b>Paraffin-embedded samples of 36 cases of MCL and a control group of 71 cases of small B-cell lymphomas were retrieved from archive materials. Immunohistochemical staining for cyclin D1 and semi-nested PCR for t(11;14) were detected in all samples. House-keeping gene beta-actin was used to detect the quality of DNA.</p><p><b>RESULTS</b>(1) Cyclin D1 was expressed in 26 of the 36 MCL (72.2%). There was no cyclin D1 expression in the control group. (2) beta-actin DNA was detected in 101 of the 107 tumor cases (94.4%). t(11;14) was detected in 22 of the 36 MCL. Translocation was not found in control group. The positive rate for t(11;14) was 64.7% in MCL after exclusion of 2 cases which were negative for both t(11;14) and beta-actin. (3) 29 cases were positive for cyclin D1 and/or t(11;14), the positive rate reached 80.5%.</p><p><b>CONCLUSION</b>The combined detection of cyclin D1 and t(11;14) in paraffin-embedded tissues is found to be a specific and feasible method for diagnosis and differential diagnosis of mantle cell lymphoma.</p>
