Objective To investigate the expression of MIB1 and Topo Ⅱα,and their relation to the clinical grades and biological behavior in diffuse large-B cell lymphoma(DLBCL).Methods 66 csses of DLBCL were selected from the Pathological Department of Shanxi Tumor Hospital from 1996 to 2001.An ABC method was used to detect the expression of CD3,CD20,CD79α,Pax5,and a double immunostaining technique ABC-DAB/SABAP-vector red and ABC-DAB/immunogolden was used to detect the expression of MIB1 and Topo Ⅱα.Results Expression of MIB1 and Topo Ⅱα were increased along with the clinical stage of the DLBCL.There was a significant difference between ealier stage(Ⅰ,Ⅱ)and later stage(Ⅲ,Ⅳ)in DLBCL(P＜0.05).The expression of MIB1 and Topo Ⅱα were also significantly related to the survival rate(r=-0.487,0.251 respectively,P＜0.05).Conclusion Expression of MIB1 and Tope Ⅱα may serve as two independent prognostic predictors in DLBCL.

Objective To investigate the genetic changes of FGR and TP73 in PTCL-NOS, in order to verify the results of our previous a-CGH study and to explore their role on the pathogenesis of PTCL-NOS. Methods A total of 34 cases, of which 19 cases were examined by a-CGH, were investigated by interphasedual-colour FISH using homemade site-specific probes of FGR and TP73 by using a labelling method of nick translation and commercial probe CEP1. Results In general, 7 of 34 (20.6 %) cases of PTCL-NOS showed genetic aberrations, of which 4 cases had changes on both of the loci of FGR and TP73, including 3 cases of amplification and 1 loss of heterozygosity (LOH), 1 case of FGR amplification and other 2 TP73 amplification only. CEP1 amplification was detected in 4 cases (11.8 %), simultaneously associated with FGR/ TP73 gene amplification. Kaplan-Meier survival analysis indicated there was a trend that the group with genetic changes had a poorer prognosis than the group of non-genetic changes, and so as the group of TP73 genetic changes compared with the group of TP73 non-genetic changes, although their was no statistical significance (P >0.05). Conclusion The outcome of this study partially verified the results of a-CGH, and aberration of lymphoma-related genes FGR and TP73, and the amplification of CEP1 may play a significant role in the pathogenesis of PTCL-NOS.

Objective To analyze the genetic changes in peripheral T-cell lymphoma, not otherwise specified (PTCL-NOS) and to find the key molecular aberrations underlying its pathogenesis. Methods A total of 37 cases of PTCL-NOS were investigated by 1Mb resolution array comparative genomic hybridisation (Array-CGH), in which 9 cases were further studied by using a Tile path array-CGH. DNA extraction, clonality analysis and histologic review were conducted to exclude 6 cases with polyploidy and without obvious genetic imbalances from this study. Results In general, there was a considerable overlap in the CGH profiles in many PTCL-NOS cases. The most recurrent regions of genomic gains were lp36.13-1p36.32, 7q22.1, 7q36.1-7q36.3, 7q32.1-7q32.3, 7q22.1-7q34,9p11 .2-9q12 and 9q33.3-9q34.3. The most recurrent regions of genomic losses were 1p12-1p21.1 and 13q14.11-13q14.3. Conclusion Genomic gains and losses are frequently identified in PTCL-NOS with array-CGH, in which patients with multiple chromosomal alterations (≥6regions) have poor prognosis. These genomic profiles are broadly important to reveal a distinct subgroup with genetic alterations and to find the key genomic imbalance of PTCL-NOS.

Objective To study the expression of miR-320d in diffuse large B cell lymphoma (DLBCL),and its correlation with prognosis of DLBCL.Methods Sixty cases of DLBCL with the follow-up data were collected from Shanxi Cancer Hospital,and were examined by immunohistochemical EnVision method for CD3,CD10,CD20,bcl-6 and Mum-1.The DLBCL were classified into germinal center B cell-like (GCB) and non-germinal center B cell-like (non-GCB) subtypes according to Hans' algorithm.Agilent Human miRNA Microarray 16.0 was used to select the miRNAs on 24 cases paraffin-embedded tissue of DLBCL.The expression levels of miR-320d in 62 cases were examined by TaqMan real-time polymerase chain reaction.Eleven cases of reactive hyperplasia of lymph node were selected as control.Results In 62 cases of DLBCL,22 cases (35.5 ％) were GCB and 40 cases (64.5 ％) were non-GCB subtypes.The expression of miR-320d in GCB was 3.43 times as much as non-GCB subtypes (P =0.034),and in reactive hyperplasia of lymph node it was 5.65 times as much as in DLBCL (P ＜ 0.001).The low expression groups of miR-320d was significantly correlated with shorter overall survival (P =0.021).Multivariate Cox proportional hazard regression analysis (including the IPI scores) revealed that the down-regulated miR-320d was the independent predictor in DLBCL (RR =2.434,95 ％ CI 1.148-5.159,P =0.020).Conclusions The down-regulated expression of miR-320d might be considered as a distinct subgroup with poor prognosis.

Objective To study the expression of PTEN et al and their significance in T lymphoblastic lymphoma/leukaemia (T-LBL/ALL). Methods Seventy-six cases of T-LBL/ALL were studied by using immunohistochemistry (EnVision method) for CD3, CD7, CD10, CD20, CD23, CD43, CD45RO, CD99, TdT, MPO and PTEN. Follow-up was included. Results In the Seventy-six cases of T-LBL/ALL, the percentages of tumor cells expressing TdT, CD99, CD3, CD7, CD45RO and CD43 were 93.42%, 94.74%, 67.12%, 92.11%, 36.85%,and 51.33%, respectivly while MPO, CD20 and CD23 were all negative. The index of Ki-67 expression higher than 80 % was found in 27 and ≤80% in 49 cases. The expression of PTEN (64.47 %) in T-LBL/ALL was lower than that of in reactivated lymphoid tissue (100%, P<0.05). PTEN was reversely correlated with stage,Ki-67 expression and LDH level (P<0.05). CD3-positive cases were more than CD3-negative cases in abnormal LDH level (P<0.05). Follow-up data was obtained in 50 cases, ranging from 1 to 108 months. The overall survival rate was 35.8 %, with median survival time 330 days. No prognostic significance was found in the expression of PTEN, CD3, CD7, CD10, CD43, Ki-67 and CD45RO (P >0.05). Conclusion The antibodies of CD3,CD7, CD10, CD20, CD43, CD45RO, CD99, TdT, MPO and Ki-67 were very helpful for the diagnosis of T-LBL/ALL.Down-regulation of PTEN may play an important role on the development of T-LBL/ALL.
