Résumé

OBJECTIVE@#To evaluate the risk factors affecting thromboembolism in lymphoma patients with chemotherapy.@*METHODS@#Three hundred and four consecutive lymphoma patients treated by chemotherapy between January 2012 and July 2019 were enrolled and retrospectively analyzed, consisting of 111 patients with thromboembolism and 193 without thromboembolism. Univariate analysis was used to compare the clinical characteristics and related laboratory examination between the patients, while multivariate Logistic regression analysis were used to identify the risk factors affecting thromboembolism in lymphoma patients with chemotherapy.@*RESULTS@#Univariate analysis showed that the female, BMI <18.5 or >24, ≥60 years old, with abnormal platelets before chemotherapy, prolonged single hospitalization days and patients at Ann Arbor stage III and IV could increase the incidence of thromboembolism in lymphoma patients treated by chemotherapy. Multivariate Logistic regression analysis showed that abnormal platelet count before chemotherapy, patients at Ann Arbor stage III and IV, and female were all the independent risk factors affecting thromboembolism in lymphoma patients thromboembolism after chemotherapy (P<0.05).@*CONCLUSION@#For lymphoma chemotherapy patients, female, abnormal platelet count before chemotherapy and Ann Arbor stages III and IV show a significantly higher risk for thromboembolism. Thus, preventive anticoagulation therapy is recommended.

Résumé

OBJECTIVE@#To evaluate the clinical value of serum amyloid A (SAA1/2) and misfolded transthyretin (TTR) for relapsed/refractory diffuse large B-cell lymphoma (R/R DLBCL) patients.@*METHODS@#30 R/R DLBCL patients were enrolled as observation group, 20 remission/stabilization DLBCL and 10 chronic lymphadenitis patients were enrolled as control group. SELDI technique, Tris-Tricine sodium dodecyl sulfate-polyacrylamide gel electro-phoresis, the shotgun-LTQ-MS method, and bioinformatics technique were used to detected and analyzed SAA and TTR in R/R DLBCL patients. SPSS 21.0 software was used to analyze the relationship between the high expression of SAA, misfolded TTR in serum and the clinicopathological features, survival time of R/R DLBCL. patients Chi-square test was used to analyze clinical count data, Kaplan-Meier curve was used for survival analysis, and Log-Rank test was used to compare single-factor survival differences.@*RESULTS@#The high expression of SAA and TTR (SAA@*CONCLUSION@#Both SAA and misfolded TTR are poor prognosis factors of R/R DLBCL patients.

Résumé

OBJECTIVE@#To investigate the effect of P53 expression on prognosis of patients with double expressor lymphoma(DEL) and the interaction between the expression of MYC, BCL2 and P53 in diffuse large B-cell lymphoma(DLBCL).@*METHODS@#Eighty-eight patients with newly diagnosed DLBCL from 1st September 2012 to 31th May 2018 in Shanxi Dayi Hospital affiliated to Shanxi Medical University were selected. The expressions of MYC、BCL2、P53、CD10、BCL6、MUM and Ki-67 were tested by immunohistochemistry method. The overall survival of patients was analyzed by the Kaplan-Meier method and compared by the log-rank test. The prognostic effect of MYC, BCL2 and P53 expression was analyzed by univariate and multivariate analysis.@*RESULTS@#Compared with patients without P53 expression, the patients with P53 expression had higher LDH level, higher NCCN-IPI scores, lower response to chemotherapy,poorer overall survival(OS) and a higher rate of death(P0.05). Among lymphoma patients with MYC/P53, MYC/BCL2 and BCL2/P53 co-expression, the patients with MYC/P53 co-expression had the worse OS (3 year OS rate:31.6%), followed by the subgroup of patients with MYC/BCL2/P53(3 year OS rate:46.2%), patients with MYC/BCL2/P53 expression(3 year OS rate: 636%) showed a longer OS compared with the other two subgroups(P<0.05). Multivariate analysis demonstrated that P53 expression and NCCN-IPI were independent prognostic factors in this patient cohort.@*CONCLUSION@#P53 and MYC expressions have a synergistically negative prognostic effect in DLBCL patients. P53 expression augments the negative prognostic effect of MYC/BCL2 double expression. Patients with MYC/P53 co-expression have a worse prognosis in comparison with the patients with MYC/BCL2 double expression.

Résumé

<p><b>OBJECTIVE</b>To investigate the clinical characteristics, pathologic types and prognostic factors of Hodgkin lymphoma (HL).</p><p><b>METHODS</b>Retrospective analyses of clinical data of 62 HL patients, including 45 from Peking University third hospital and 17 from Shanxi Dayi hospital.</p><p><b>RESULTS</b>Sixty-two HL patients accounted for 5.66% of the total newly diagnosed patients with lymphoma (45/795) in the period with a ratio of male:female as 2.1:1. All the pathological types were classical Hodgkin lymphoma (cHL), including 33 cases (53.2%) of nodular sclerosis type (NS) and 19 cases (30.6%) of mixed cell type (MC). Of the 56 cases followed up, the total responsive rate was 92.9% , and 2- , 3- and 5- year overall survival (OS) rates were 97.7%, 92.2% and 80.5% respectively with the median OS as 45 (8-184) months. Analyses of the prognostic factors indicated that the involvement of spleen(P=0.042)and German Hodgkin Study Group(GHSG) risk score (P=0.002) were poor factors with statistic significance.</p><p><b>CONCLUSION</b>HL is one of the curable malignant tumors, 5-year OS rate was 80.5% in this group. After recurrence, part of patients developed slowly and could be salvaged with second-line therapy with high remission rate. GHSG scoring system and involvement of spleen could predict the prognosis in HL setting.</p>

Résumé

ObjectiveTo identify serum specific protein biomarkers for the early diagnosis of lymphoma patients by using surface enhanced laser desorption/ionization time of flight mass spectrometry (SELDI-TOF-MS)protein chip array.MethodsSELDI-TOF-MS technique and weak cation exchanger (WCX2)protein chip were used to detect the serum proteomic patterns of 96 patients with lymphoma (86 patients with non-Hodgkin lymphoma and 10 patients with Hodgkin lymphoma)and 30 normal control.The serum level of LDH were measured by biochemical methods,the serum level of β2-MG and CA125 were detected by enzyme-linked immunosorbent assay (ELISA).ResultsFour protein peaks pattern mass/charge ratio (M/Z) 6880,8564,8692 and 13751 were decreased in lymphoma patients,and they could be used to distinguish lymphoma from healthy people and other malignant tumors.Their sensitivity and specificity were 82.29 % and 80.00 %,78.13 % and 73.30 %,75.00 % and 80.00 %,71.88 % and 83.30 % respectively in lymphoma patients.When it was used to early diagnosing lymphoma in stage Ⅰ or Ⅱ,the sensitivity of four protein peaks pattern (M/Z 6880,8564,8692 and 13 751) were 77.55 %,71.43 %,71.43 % and 67.35 %respectively and the specificity of all four protein peaks pattern were 100.00 %.Four protein peaks pattern sensitivity were higher than LDH,CA125 and β2-MG respectively.ConclusionApplication of SELDI-TOF-MS can be of great potential for the early diagnosis of lymphoma patients.
