The soluble form of Fas (sFas) can block apoptosis induced by the Fas ligand in vitro. A recent report demonstrated that mice injected with sFas displayed autoimmune features. Therefore, an elevated serum concentration of sFas may be associated with lymphoproliferation and autoimmune diseases. We measured the serum concentrations of sFas in 77 patients with non-Hodgkin's lymphoma (NHL) [8 angioimmunoblastic T-cell lymphoma (AIL), 12 T-cell NHL, 53 B-cell NHL, and 4 natural killer-cell NHL]. Elevated concentrations of sFas were detected only in AIL, which is frequently accompanied by autoimmune diseases (P < 0.005 compared with age-matched controls). A possible association of sFas and autoimmune features in AIL is discussed. Am. J. Hematol. 58:334–336, 1998. © 1998 Wiley-Liss, Inc.  相似文献

Higher pretreatment serum hepatocyte growth factor (HGF) levels were observed in patients with multiple myeloma and Hodgkin's disease, but not in those with non-Hodgkin's lymphoma (NHL). We examined patients' serum levels at diagnosis using enzyme-linked immunosorbent assay and histological expression of HGF in pathological specimens of lymphoma, in relation to clinical features. The subjects were 77 NHL patients and 40 healthy controls. The serum levels of HGF in NHL patients at diagnosis were significantly higher than those in healthy controls (median 1019 vs. 689 pg/mL, P < 0.001). At diagnosis, patients with more than two sites of extranodal involvement (P = 0.001), higher scores of international prognostic index (P = 0.015), and advanced Ann Arbor stage (P = 0.023) had a higher level of serum HGF. Although the association of pretreatment serum HGF level and survival was not significant, a correlation of serial change of serum HGF levels with treatment response was found in limited cases. Furthermore, HGF expression of lymphoma tissues was shown in 18 of 24 (75%) different NHL subtypes, including most of the diffuse large B cell lymphoma (12 of 15, 80%). In conclusion, our study showed higher pretreatment serum HGF levels in NHL patients, which was related to clinical features; and the serial change of HGF seemed to parallel the treatment response. The pathogenic role of HGF in NHL patients was further highlighted by a modest expression of HGF in most of the diffuse large B cell lymphoma.  相似文献

BACKGROUND/AIMS: Experimental studies have suggested that apoptosis via the Fas/Fas Ligand signaling system may play an important role in the development of acute liver failure. The aim of the study was to investigate the soluble form of Fas in patients with acute liver failure. METHODOLOGY: Serum levels of sFas (soluble Fas) were measured by ELISA in 24 patients with acute liver failure and 10 normal control subjects. Serum levels of tumor necrosis factor-alpha and interferon-gamma were also determined by ELISA. RESULTS: Serum sFas was significantly increased in patients with acute liver failure (median, 26.8 U/mL; range, 6.9-52.7 U/mL) compared to the normal controls (median, 8.6 U/mL; range, 6.5-12.0 U/mL, P < 0.0001). Levels were significantly greater in patients with acute liver failure due to paracetamol overdose (median, 28.7 U/mL; range, 12.8-52.7 U/mL, n = 17) than those due to non-A to E hepatitis (median, 12.5 U/mL; range, 6.9-46.0 U/mL, n = 7, P < 0.01). There was no relationship of sFas to eventual outcome in the patients. A significant correlation was observed between serum sFas levels and aspartate aminotransferase (r = 0.613, P < 0.01). CONCLUSIONS: The increased concentration of sFas in serum of patients with acute liver failure may reflect activation of Fas-mediated apoptosis in the liver and this together with increased tumor necrosis factor-alpha may be an important factor in liver cell loss.  相似文献

AIM: To study the expression and serum level of HBxAg,Fas and FasL in tissues of HCC patients, and to assess the relationship between HBxAg and Fas/FasL system.METHODS: Tissues from 50 patients with HCC were tested for the expression of HBxAg, Fas and FasL by S-P immunohistochemistry. Serum levels of sFas/sFasL and HBsAg/HBeAg were measured by ELISA assay. HBV X gene was detected by PCR in serum and confirmed by automatic sequencing. Fifty cases of liver cirrhosis and 30 normal controls were involved in serum analysis.RESULTS: The expression of HBxAg, Fas and FasL in carcinoma tissues was 96 %, 84 % and 98 %, respectively.Staining of HBxAg, Fas and FasL was observed predominately in cytoplasms, no significant difference was found in intensity between HBxAg, Fas and FasL (P>0.05). HBxAg, Fas and FasL might express in the same area of carcinoma tissues and this co-expression could be found in most patients with HCC. The mean levels of sFas in serum from HCC, cirrhosis and normal controls were 762.29±391.56 μg@ L-1 835.36±407.33 μg@L-1 and 238.27±135.29 μg@L-1. The mean levels of sFasL in serum from HCC, cirrhosis and normal controls were 156.36±9.61iμg@ L-1, 173.63±18.74 μg@L-1 and 121.96±7.83 μg@ L-1.Statistical analysis showed that both sFas and sFasL in HCC and cirrhosis patients were significantly higher than those in normal controls (P<0.01). Serum HBV X gene was found in 32 % of HCC patients and ,46 % of cirrhotic patients.There was no significant relationship between serum level of sFas/sFasL and serum X gene detection (P>0.05). Eight percent of HCC patients with negative HBsAg and HBeAg in serum might have X gene in serum and HBxAg expression in carcinoma tissues.CONCLUSION: Our data suggest that HBxAg and Fas/FasL system plays an important role in the development of human HCC. Expression of HBxAg can leads to expression of Fas/FasL system which and reverse apoptosis of hepatocellular carcinoma induced by FasL.  相似文献

BACKGROUND: Apoptotic cell death is the major form of myocardial damage produced by coronary ischemic events. OBJECTIVE: To assess whether circulating levels of soluble Fas (sFas), an inhibitor of apoptosis, and sFas ligand, an inducer of apoptosis, in patients with coronary artery disease are greater than normal. METHODS: Forty-seven patients [acute myocardial infarction (AMI) in 17, old myocardial infarction (OMI) in 15, stable angina in 15] and 10 normal control subjects participated in this study. Serum levels of sFas and sFas ligand in all patients were measured, and cardiac catheterizations were performed. RESULTS: Serum levels of sFas were greater than normal only in patients with AMI (4.6 +/- 1.6 ng/ml); the levels were significantly higher than those in patients with OMI (2.1 +/- 0.6 ng/ml) and stable angina (2.2 +/- 0.5 ng/ml), and in normal subjects (2.0 +/- 0.6 ng/ml; P < 0.0001). However, there was no difference among serum levels of sFas ligand for all groups. For patients with AMI, there was no significant correlation between serum levels of sFas and peak levels both of plasma creatine phosphokinase and of plasma myosin light chain type I as clinical indexes of infarct size. However, there were significant correlations between serum levels of sFas and both pulmonary artery wedge pressure (r = 0.767, P = 0.0003) and left ventricular end-diastolic pressure (r = 0.629, P = 0.03). CONCLUSIONS: Circulating sFas increases in concentration in relation to the severity of hemodynamic conditions in patients with AMI, but it is independent from size of infarct. Therefore, circulating sFas could play an important role as the marker of pathophysiologic conditions associated with cardiomyocyte apoptosis in AMI.  相似文献

Clinical progression of B-cell chronic lymphocytic leukemia (B-CLL) depends on survival and accumulation of leukemic cells, regulated in part by physical cell contact and soluble molecules. Here we have studied the Fas/FasL system in relation to clinical progression in B-CLL. Serum levels of soluble Fas (sFas) and FasL (sFasL) were determined by ELISA in 43 progressive and 40 non-progressive B-CLL patients and in 21 control individuals. Correlation between sFas serum levels and clinical progression, stage and survival were statistically analyzed. We found high levels of sFas in B-CLL sera correlated with disease progression (p<0.01). In addition, higher sFas levels were found in patients in stages II, III and IV in comparison to patients in stage 0 (p<0.05, p<0.01, p<0.03, respectively). Survival was significantly shorter for patients with > or =6 ng/ml sFas serum levels, although a multivariate analysis did not show sFas to be a significant independent prognostic factor. Fresh B-CLL cells showed only low levels of membrane expression, which were not correlated to sFas levels in serum. In vitro activation of B-CLL cells increased Fas expression, as reported earlier, and induced cells to release sFas into the supernatant. In conclusion, our results indicate that sFas in serum may be a useful parameter for the prediction of clinical progression in B-CLL.  相似文献

Several reports recently found that patients with B cell non-Hodgkin's lymphoma (NHL) had a higher carrier rate of hepatitis B surface antigen (HBsAg). The current study aimed to examine the hepatitis B virus (HBV) infection status of NHL patients in Taiwan, an HBV-endemic area. Serum HBV and serum hepatitis C virus were measured in 471 NHL patients and 1,013 non-lymphoma cancer patients enrolled between February 2000 and March 2007. Furthermore, nested polymerase chain reaction of HBV-DNA was used to examine the sera from selected patients in these two populations and healthy volunteers for the presence of occult HBV infection. The infection rates (as indicated by the rates of HBsAg and occult HBV) were compared between different groups. There was a higher incidence of HBV infection in B cell NHL patients (23.5%), especially patients with diffuse large B lymphoma, than solid tumor patients (15.6%, P = 0.001). Among HbsAg-negative patients, those with B cell NHL had a higher prevalence of occult HBV infection (6%) than those with non-lymphoma solid tumors and healthy volunteers, 0% and 0.9%, respectively (P = 0.005). B cell NHL patients, even HBsAg-negative B cell NHL patients, but not T cell NHL patients, have a higher incidence of HBV infection than patients with solid tumors. Our findings support the etiologic role of HBV infection in B cell NHL.  相似文献

Introduction  We previously reported that serum concentrations of soluble Fas (sFas) predict the clinical outcome of patients with diffuse large B cell lymphoma (DLBCL) after treatment with CHOP but without rituximab (R). Here, we investigated whether the role of sFas as a prognostic factor remains valid in the R-CHOP era. Patients  We treated 132 patients with DLBCL between October 1995 and September 2002 (group A: without rituximab), and 75 between December 2002 and March 2007 (group B: with rituximab). The patients received eight cycles of CHOP or THP (tetrahydropyranyl-adriamycin)-COP before September 2002, and R-CHOP or R-THP-COP after October 2002. The distribution of patients according to the International Prognostic Index did not significantly differ between the groups. Results  The 5-year overall survival (OS) rates for patients with sFas levels of ≥3.0 and <3.0 ng/ml in group A were 19.8 and 61.9% (P < 0.0001), whereas the 3-year OS rates in group B were 54.7 and 92.2% (P < 0.01), respectively. Multivariate analysis using the proportional hazards model revealed that sFas most significantly correlated with overall survival (P < 0.05). Conclusion   Serum sFas is thus a useful tool for selecting the appropriate therapeutic strategy for DLBCL.  相似文献

Circulating nuclear matrix protein in Graves' disease   总被引:3,自引:0,他引:3  
Hara H  Morita Y  Sato R  Ban Y 《Endocrine journal》2002,49(3):343-347
The Fas/Fas ligand system induces apoptosis, while soluble Fas (sFas) blocks the system and soluble Fas ligand (sFasL) functions to induce apoptosis. The assay of nuclear matrix protein (NMP) released from dead or dying cells can be used to quantitate cell death. Therefore, we evaluated the relationship among serum levels of NMP, sFas, and sFasL in patients with Graves' disease. We measured serum levels of sFas, sFasL, NMP, thyroid hormones and TSH receptor antibody in 20 normal control subjects (5 men, 15 women; mean age, 44.3 years), 32 patients with untreated Graves' disease (4 men, 28 women; mean age, 44.1 years), and 10 patients with Graves' disease treated by methimazole (3 men, 7 women; mean age 39.2 years). Serum NMP was significantly lower (10.4 +/- 4.3 IU/ml, p < 0.02) in patients with untreated Graves' disease than in patients with treated Graves' disease (16.4 +/- 7.3 IU/ml) and control subjects (15.3 +/- 8.9 IU/ml). Serum sFas and sFasL were significantly higher in patients with untreated Graves' disease than in patients with treated Graves' disease and in control subjects. In the patient groups with Graves' disease, serum NMP was negatively correlated with sFas (r = -0.612, p < 0.001) and serum sFas was positively correlated with FT4 (r = 0.360, p < 0.05) and TRAb (r = 0.384, p < 0.05). Serum NMP was correlated with sFas. These results suggest that serum NMP is decreased in patients with untreated Graves' disease, and that cell death or apoptosis in patients with Graves' disease is affected by soluble Fas under the influence of thyroid function.  相似文献

BACKGROUND: Recently investigators have worked to identify prognostic factors in non-Hodgkin's lymphoma (NHL) so an appropriate therapeutic plan can be put in action. The aim of the present study was to assess the prognostic significance of serum soluble tumor necrosis factor receptor (sTNF-R) 2 in aggressive NHL. METHODS: One hundred and ten consecutive patients with aggressive NHL who were previously untreated (diffuse large B-cell lymphoma; 94, peripheral T-cell lymphoma; 16) were prospectively enrolled in this study between 1997 and 2002. The patients were treated with 6-8 cycles of CHOP or THP-COP regimens. RESULTS: High serum sTNF-Rs level was associated with some poor prognostic factors and low complete remission rate. Patients with high sTNF-R1 (4 ng/mL and over) and sTNF-R2 (15 ng/mL and over) at onset had significantly lower survival rates (5 yr: 19%, 19%) than those with low sTNF-R1 (under 4 ng/mL) and sTNF-R2 (under 15 ng/mL) (62% and 69%), respectively (P < 0.0005 and 0.0001). Multivariate analysis employing sTNF-R2 and some conventional prognostic factors demonstrated that a combination of sTNF-R2 and performance status, and that of sTNF-R2, sIL-2R, and LDH were significant prognostic factors for poor overall survival and for poor event-free survival, respectively. In addition, we attempted to use sTNF-R2 in combination with the international prognostic index (IPI). The patients in the high risk group and those with high sTNF-R2 in the low-intermediate (LI)/high-intermediate (HI) risk group had significantly lower survival rates than the patients in the low risk group and those with low sTNF-R2 in LI/HI risk group (P < 0.0001). CONCLUSIONS: The results suggest that a high serum sTNF-R2 level predicts a poor prognosis in aggressive NHL and may be a useful biomarker for selecting appropriate treatment when used in combination with the IPI.  相似文献

We have correlated the serum levels of TNF alpha and soluble TNF receptor superfamily members with clinico-pathologic parameters in patients of Hodgkin's disease (HD, N = 26) and non-Hodgkin's lymphoma (NHLs, N = 35). HD patients had significantly higher levels of TNF alpha, sTNFRI, and sTNFRII in serum while NHL patients had significantly higher levels of sTNFRI, sTNFRII, sCD27, and sFas as compared to controls. In NHL patients the levels of sCD27 correlated directly and significantly with the high-stage disease, bone marrow involvement, lymph nodal presentation, and serum LDH levels. Similarly in NHL patients, levels of sFas also correlated directly and significantly with the presence of high stage disease. HD patients with B symptoms had significantly higher levels of sTNFRII.  相似文献

Fas ligand (Fas-L) is a lethal cytokine that promotes apoptosis, as well as the immune and inflammatory responses through cross-linking of the Fas receptor. Soluble Fas (sFas) blocks apoptosis by inhibition of binding between Fas and Fas-L or soluble Fas-L. The aim of the work was to investigate the prognostic significance and role of the serum levels and urinary excretion of sFas in various types of adult chronic primary glomerular diseases. We studied 53 patients with primary glomerular diseases (5 minimal change--MC; 4 focal glomerulosclerosis--FS; 4 membranous nephropathy--MN; 12--mesangial proliferative GN--MesPGN; 18 IgA nephropathy--IgAN; 6 membranoproliferative GN--MPGN, and 4 extracapillaris GN--ExGN) and 10 healthy persons. Renal biopsies were evaluated by light and fluorescence microscopy. Concentrations of sFas were measured by ELISA (BIOSOURCE international kits). The treatment of patients consisted of 3 to 5 i.v. methylprednisolone pulses (1.0 g per single dose, average total 1.0 g/20 kg given alternate days) followed by oral prednisone 20 to 25 mg/day and six monthly i.v. cyclophosphamide 0.6 g/l m2/month. The serum levels and urinary excretion of sFas in the patients with MC, and MN were similar to controls. However, the serum levels and urinary excretion of sFas were insignificantly elevated in patients with MesPGN, MPGN, FS, and ExGN, but significantly elevated in patients with IgAN as compared with control and patient groups. In patient groups serum Cr showed significant correlations with interstitial volume in renal biopsy, and urinary excretion of sFas, but serum levels of sFas with interstitial volume. Serum levels and urinary secretion of sFas in patients with renal insufficiency (Cr > 1.3 mg%) and reduction of proteinuria < 50% after 1-year treatment was higher before treatment than in another patient groups. These results suggest that increased serum and urinary excretion of sFas in proliferative glomerulonephritis PGN (particularly in IgAN) may inhibit apoptosis in glomeruli and may be one of the progressing factors in PGN.  相似文献

The purpose of this retrospective study, the largest unselected series in our country, was to illustrate the clinicopathological features of non-Hodgkin's lymphoma (NHL) classified according to the World Health Organization (WHO) classification of lymphoid neoplasms. A retrospective analysis was conducted and clinical features of histological subtypes were established in 810 patients (age > or = 15 years) with NHL who were treated at 8 major centers representative of Greece. There were 435 males and 375 females 95% of them aged >30 years. B symptoms were present in 34% of the patients, while 45.3% had stages I-II and 54.6% had stages III-IV. LDH was increased in 37% of the patients. B cell lymphomas formed 88% of the cases whereas T cell lymphomas formed 12% of the total. Indolent lymphomas accounted for 31.1%, aggressive ones for 66.7% and very aggressive ones for 2.4% of all NHLs. Among indolent lymphomas extranodal ones (MALT B cell lymphoma) were the most common subset while follicular lymphoma grade I and II and small lymphocytic ones presented with equal frequency. Among the aggressive lymphomas diffuse large cell lymphoma (DLCL) was the most common subtype; this entity along with large-cell immunoblastic lymphomas accounted for 45.2% of all B cell lymphomas. Among the T cell lymphomas, peripheral T cell lymphomas and anaplastic large cell lymphomas of the T/null-cell type were the most common subtypes. The most common extranodal presentation was the gastrointestinal tract (GI). Next in frequency were primary extranodal NHL of the head and neck region. MALT B cell lymphomas were found in almost half of the patients with GI tract NHL, whereas in all other extranodal places DLCL was the predominant histological subtype. The median survival for indolent and aggressive NHL was 123.5 and 55.5 months, respectively. This is the first report of a large series of malignant lymphomas in Greece using the WHO classification. It appears that there are no significant differences between NHL in Greece and other large series as far as clinical and extranodal presentation is concerned. The frequency of follicular lymphoma in the current study is comparable to that reported from Asian countries and mainland Europe, but lower than that of US and Northern European series. There were no important differences in the incidence of the remaining histological subtypes between Greece and other European countries.  相似文献

Fas/FasL-mediated apoptosis results in the destruction of thyrocytes in chronic autoimmune hypothyroidism (CAIH). In this study, we examined the serum levels of soluble Fas (sFas) and soluble sFas ligand (sFasL) in euthyroid patients with chronic autoimmune hypothyroidism, who were taking levothyroxine (euthyroid, LT4-CAIH), to investigate the possible role of thyroid hormone therapy in down-regulation of apoptotic factors. Fifty euthyroid patients with CAIH on levothyroxine (median of duration 36 months, range 6-228 months) were compared with 75 age- and sex-matched healthy individuals. Serum levels of soluble Fas and soluble Fas Ligand, autoantibodies to thyroid peroxide and thyroglobulin were measured using ELISA. Serum levels of sFas were significantly higher in the euthyroid, LT4-CAIH group [median 9.12 ng/ml, interquartile range (7.86-10.72 ng/ml)] than in the controls [6.11 ng/ml (5.60-6.81 ng/ml)] (P < 0.0001). Compared with controls [80.33 pg/ml (68.22-103.70 pg/ml)], the euthyroid, LT4-CAIH group [125.71 pg/ml (106.11-149.48 pg/ml)] had significantly higher levels of sFasL (P < 0.0001). In a chronological study, there was no significant correlation between sFas, sFasL, and the duration of levothyroxine therapy. In conclusion, normalization of serum sFas and sFasL levels cannot be achieved during levothyroxine treatment in patients with CAIH. It appears that levothyroxine therapy has no important effect on down-regulation of apoptotic factors in CAIH. Thus, like thyroid autoantibodies, monitoring of serum levels of sFas/sFasL is not indicated during thyroid hormone therapy.  相似文献

The Fas/Fas Ligand system is a major apoptosis signaling pathway that is up-regulated in patients with chronic heart failure (CHF). Serum soluble Fas (sFas) levels increase in proportion to the CHF severity and may have prognostic value, therefore, sFas is a promising biomarker of heart failure. In this study, we attempted to identify the determinants of sFas levels in patients with CHF. Serum levels of tumor necrosis factor (TNF)-α and its soluble receptors (sTNF-R1 & sTNF-R2), interleukin (IL)-6, soluble IL-6 receptor (sIL-6R), glycoprotein (gp)130, and sFas were measured in 106 patients with CHF and 39 controls. All subjects performed a symptom-limited cycle ergometer exercise test with expired gas analysis. CHF patients had higher levels of TNF-α, sTNF-R1, sTNF-R2, IL-6, and gp130. Serum levels of sFas (controls versus CHF; 2.60 ± 0.88 versus 3.38 ± 1.23 ng/mL, P = 0.0004) were higher in CHF. On univariate analysis, age (P = 0.0003), NYHA functional class (P = 0.0012), peak VO2 (P < 0.0001), plasma norepinephrine (P = 0.0013), log IL-6 (P < 0.0001), log TNF-α (P = 0.0002), log sTNF-R1 (P < 0.0001), and log TNF-R2 (P < 0.0001) were significantly related to log sFas levels. Multivariate analysis showed that age and log IL-6 and log sTNF-R1 levels were independently associated with log sFas levels (overall R = 0.603, P < 0.0001). Serum levels of sFas were increased in patients with CHF, and age and serum IL-6 and sTNF-R1 levels were independent determinants of sFas levels. These data suggest that proinflammatory cytokine activation is linked to the Fas/Fas Ligand system in patients with CHF.  相似文献

Death during the induction phase of chemotherapy remains a common event in patients with aggressive non-Hodgkin's lymphoma (NHL). In a series of patients with aggressive NHL homogeneously treated with intensive induction chemotherapy [ACVB (doxorubicin, cyclophosphamide, vindesine, bleomycin, prednisone) regimen], we determined the clinical and biological parameters that were predictive of early death. Early death was defined as death, for whatever reason, occurring within 100 d of randomization. Predictive factors were identified by logistic regression and an index predictive for individual risk of early death was designed. Among the 2210 patients treated with ACVB, there were 162 (7.3%) early deaths. There was no significant reduction in the rate of early death between 1987 and 1998. In a multivariate analysis, age > 60 years, Eastern Cooperative Oncology Group performance status > 1, serum lactate dehydrogenase > normal, serum albumin < 30 g/l, leucocyte counts > 10 x 10(9)/l and haemoglobin levels < 8.5 g/dl were found to be independent predictive factors for early death. An early death index was designed, enabling the evaluation of the individual risk of early death in young (range 2-31% risk of early death) and elderly patients (range 5-53%). Clinical and biological parameters available at diagnosis can help physicians identify patients with aggressive lymphoma at low or high risk of early death.  相似文献

The soluble decoy receptor 3 (DcR3) is a member of the tumor necrosis factor receptor superfamily whose overexpression has been observed in several human malignancies. Survivin is one of the inhibitors of apoptosis proteins that are thought to play an important role in the pathogenesis of malignancies. We aimed to evaluate the expression of DcR3 in relation to survivin in B cell non-Hodgkin`s lymphoma (NHL) and then we focused on patients with diffuse large B cell non-Hodgkin’s lymphoma (DLBCL) (50 cases) and correlated DcR3 expression with survivin expression and other prognostic parameters. Fifteen subjects with reactive lymphoid hyperplasia were included as controls. The expression of DcR3 and survivin were analyzed by immunohistochemistry on formalin-fixed paraffin-embedded lymph node sections from 80 cases of B cell NHL and 15 controls. Bone marrow biopsy sections of patients were also immunostained with the previous markers. Results: DcR3 expression was found in 32.5 % of B cell NHL patients versus 6.7 % of controls (p <0.001) and was associated with the aggressive/highly aggressive subtypes. DcR3 was strongly expressed in 30 % of DLBCL patients, where it was associated with survivin expression, high international prognostic index (IPI), the presence of extra nodal disease, ECOG performance status >1, reduced remission rates and shorter event-free survival. The expression of survivin was 40 % in B cell NHL patients versus 13.3 % in the control group (p <0.001). The expression of survivin in aggressive/highly aggressive B cell NHL was significantly higher than that in indolent B cell NHL. Survivin expression has been detected in 44 % of the DLBCL patients and was associated with their clinical stage and shorter event-free survival (p?=?0.026). Bone marrow biopsy sections from DLBCL patients showed significant DcR3 and survivin over expressions in sections with infiltration by lymphoma cells than sections with no infiltration. Conclusion: DcR3 expression was associated with other prognostic factors including survivin, reduced remission rates, and shorter event-free survival. Survivin is closely related to aggressive/highly aggressive subtypes of B cell NHL and is associated with shorter event-free survival. Both DcR3 and survivin expressions on bone marrow sections can be of help in diagnosing bone marrow infiltration.  相似文献

Patients with aggressive non‐Hodgkin lymphoma (NHL) who relapse after autologous stem cell transplantation (ASCT) have a poor prognosis. Additional therapy is often poorly tolerated, and new treatment modalities are needed. This efficacy and safety study was a retrospective analysis of two phase II trials (NHL‐002 and NHL‐003) that studied single‐agent lenalidomide in patients with relapsed/refractory aggressive NHL with prior (n = 87) compared with no prior ASCT (n = 179). The overall response rate in the ASCT group was 39% [14% complete response (CR)], including 29% in patients with diffuse large B‐cell lymphoma, 63% in mantle cell lymphoma, and 60% in transformed lymphoma. The timing of transplant relative to receiving lenalidomide had no effect on outcomes. Median progression‐free survival for the ASCT group was 3·7 months (16·9 months for patients in CR; 7·3 months for partial responders) at a median 12·5‐month follow‐up. Median response duration was 7·9 months. Regardless of prior ASCT, lenalidomide monotherapy was efficacious in heavily pretreated patients with aggressive, relapsed/refractory NHL, with a safety profile that was consistent with prior studies of single‐agent lenalidomide.  相似文献
