Case summary: 7 years old child presented to emergency with acute decompensated cardiac failure, ascites and tender hepatomegaly. 2D echo evaluation was suggestive of large intracardiac mass in the right atrium almost completely obstructing Tricuspid valve orifice, gross pericardial effusion and dilated Inferior Vena Cava (IVC). Emergency tumor excision surgery was performed which revealed 4 × 4 cm pinkish firm mass arising from anterior Tricuspid annulus which was completely excised. Child was extubated on postoperative day (POD) 0 and was on minimal inotropic support. Ascites reduced significantly on POD1 allowing abdominal palpation which revealed a mass in the epigastric region. This prompted evaluation by pediatrician and oncology workup suggestive of increased 18-Flouro Deoxy Glucose (18-FDG) uptake in the mediastinum, abdomen, bilateral proximal thighs, all mediastinal lymph nodal stations, bilateral lung hilar stations 10R, 10L involving all encasing the heart and great vessels with pleural deposits, Celiac trunk, superior Mesenteric Artery (SMA), Portal vein, IVC and abdominal aorta. Histo pathology Examination (HPE) and Immuno Histo Chemistry (IHC) of intracardiac mass revealed DLBCL which is metastatic in nature. Chemotherapy was started as per (French American British Lymphomes Malins B) FAB LMB-96 protocol with the child currently in the Induction phase having poor prognosis and less survival interval. Conclusion: Surgery can be considered a treatment option for metastatic intracardiac masses during emergency scenarios like cardiogenic shock to relieve obstruction along the pathway of blood flow in the heart even though we may not be able to completely excise the tumor surgically.展开更多

The hepatitis C virus(HCV) infected patients are prone to develop bone marrow or various tissue infiltrates with monoclonal B cells, monoclonal B lymphocytosis or different types of B cell non-Hodgkin's lymphoma(B...The hepatitis C virus(HCV) infected patients are prone to develop bone marrow or various tissue infiltrates with monoclonal B cells, monoclonal B lymphocytosis or different types of B cell non-Hodgkin's lymphoma(BCNHL), of which the most common are splenic marginal zone BCNHL, diffuse large BCNHL and follicular lymphoma. The association between chronic HCV infection and non Hodgkin's lymphoma has been observed especially in areas with high prevalence of this viral infection. Outside the limitations of some studies that have been conducted, there are also geographic, environmental, and genetic factors that contribute to the epidemiological differences. Various microenvironmental signals, such as cytokines, viral antigenic external stimulation of lymphocyte receptors by HCV antigens, and intercellular interactions contribute to B cell proliferation. HCV lymphotropism and chronic antigenic stimulation are involved in B-lymphocyte expansion, as mixted cryoglobulinemia or monoclonal gammopathy of undetermined significance, which can progress to BCNHL. HCV replication in B lymphocytes has oncogenic effect mediated by intracellular HCV proteins. It is also involved in an important induction of reactive oxygen species that can lead to permanent B lymphocyte damage, as DNA mutations, after binding to surface B-cell receptors. Posttransplant lymphoproliferative disorder could appear and it has a multiclonal potentiality that may develop into different types of lymphomas. The hematopoietic stem cell transplant made for lymphoma in HCV-infected patients can increase the risk of earlier progression to liver fibrosis and cirrhosis. HCV infected patients with indolent BCNHL who receive antiviral therapy can be potentially cured. Viral clearance was related to lymphoma response, fact that highlights the probable involvement of HCV in lymphomagenesis. Direct acting antiviral drugs could be a solution for the patients who did not tolerate or respond to interferon, as they seem to be safe and highly effective. The use of chemotherapy in combination with rituximab for the treatment of BCNHL in patients infected with HCV can produce liver dysfunction. The addition of immunotherapy with rituximab can increase the viral replication, and severe complications can occure especially in patients co-infected with hepatitis B virus or immune immunodeficiency virus, in those with hepatocarcinoma,cirrhosis, or liver cytolysis. But the final result of standard immunochemotherapy applied to diffuse large BCNHL patients with HCV infection is not notably worse than in those without this viral infection. The treatment of patients chronically infected with HCV and having BCNHL is complex and requires a multidisciplinary approach and the risk / benefit ratio of rituximab treatment must be evaluated especially in those with liver cytolysis.展开更多

Their clinical features,management, and outcome were assessed. Prognostic factors for survival were analyzed by univariate analysis using the Kaplan-Meier product-limit method and log-rank test.RESULTS: Twenty-five patients presented with Ann Arbor stage I PICL and 12 with Ann Arbor stage Ⅱ PICL. Thirty-five patients underwent surgery (including 31 with complete resection), 22 received postoperative chemotherapy or radiotherapy or both. Two patients with rectal tumors underwent biopsy and chemotherapy with or without radiotherapy. The 5- and 10-year overall survival (OS) rates were 51.9% and 44.5%. The corresponding diseasefree survival (DFS) rates were 42.4% and 37.7%. In univariate analysis, multiple-modality treatment was associated with a better DFS rate compared to single treatment (P = 0.001).While age, tumor size, tumor site, stage, histology, or extent of surgery were not associated with OS and DFS,use of adjuvant chemotherapy significantly improved DFS (P = 0.031) for the 31 patients who underwent complete resection. Additional radiotherapy combined with chemotherapy led to a longer survival than chemotherapy alone in six patients with gross residual disease after surgery or biopsy.CONCLUSION: Combined surgery and chemotherapy is recommended for treatment of patients with PICL.Additional radiotherapy is needed to improve the outcome of patients who have gross residual disease after surgery.展开更多

This study aimed to assess the eicacy and toxicity of dose-adjusted CHOP alone or in combination with rituximab(R-CHOP) by examining the stem cell mobilization in NHL patients. Factors afecting the collection of CD34+ cells were also explored.Methods: Our retrospective study included 39 patients eligible for autologous stem cell transplantation: 14 patients who expressed CD20 and were inancially eligible received R-CHOP for autologous peripheral blood stem cell(APBSC) mobilization; the remaining 25 patients received CHOP.Results: The median CD34+ cell yield was 7.01 × 106 cells/kg body weight(range 1.49–28.39 × 106 cells/kg body weight), with only two patients failing to meet the target CD34+ cell harvest of ber of apheresis procedures per patient was 1(range 1–3). The≥2.0 APBS× 106 cells/kg body weight. The median numC mobilization yield of the CHOP group appeared to be higher than that of the R-CHOP group(P response(CR) rate in = 0.005), whereas the success rate was similar between groups. R-CHOP elevated the completeB cell lymphoma patients as compared with CHOP(P = 0.01). No signiicant diferences in toxicity or engraftment were observed between the two groups.Conclusion: The present study demonstrated that dose-adjusted CHOP chemotherapy efectively mobilized APBSCs in NHL patients and that the addition of rituximab to dose-adjusted CHOP chemotherapy elevated the CR rate for patients with B-cell lymphoma.展开更多

It is a flattened oval organism covered with cilia, and a gullet at the anterior end. It is infrequently pathogenic for man,although epidemic buds in tropical zones have been described. The infection fundamentally affects the colon and causes variable clinic pictures, from asymptomatic to serious dysenteric forms. We present a case of parasitologically diagnosed as causes of diarrhea in a patient with non Hodgkin's lymphoma from Turkey.In order to find out the causative etiologic agent of diarrhea,stool samples were examined by native,lugol and flotation methods and we detected moving trophozoites, which were approximately 60μm long and 35μm wide.These bodies were diagnosed as Balantidium coli This case underlines that Balantidium coli should also be considered as a possible pathogen in immunocompromised patients with diarrhea.展开更多

Forty-one patients with biopsy-proven NHL and 16 healthy individuals were recruited. Pe- ripheral blood mononuclear cells (PBMCs) were isolated by density gradient centrifugation, and cEPCs were characterized by triple staining using antibodies against CD133, CD34 and vascular endothelial growth factor receptor-2 (VEGFR-2, CD309) and quantified by flow cytometry. In NHL patients, the number of cEPCs was significantly greater than in control group (P=-0.000). The cEPCs counts in patients with NHL of stage III-1V were significantly greater than in stage I -II (P=-0.010). FACS analysis revealed that the number of cEPCs in NHL patients had no correlation with the gender (P=0.401) or the pathological category (P=0.852). It was suggested that the over-expression of cEPCs in NHL patients may serve as a novel biomarker for disease progression in NHL.展开更多

In a routine follow up investigation of his chronic lymphocytic leukemia a newly detected mass in the Couinaud's segments 2 and 3 was found. No hepatitis C virus or hepatitis B virus infection or cirrhosis was evident. After laparoscopic segmentectomy the histological examination revealed a hepatocellular carcinoma. While the relation between liver parenchyma damages and hepatocellular carcinoma or non-Hodgkin's lymphoma is well known, only a few publications have focused on the coexistence of hepatocellular carcinoma and non-Hodgkin's lymphoma. With this case we demonstrate the coexistence of these diseases without having a pre- damaged liver parenchyma.展开更多

Mixed cryoglobulinemia, a B-cell "benign" lymphoproliferative disorders, represents the most closely related as well as the most investigated HCVrelated extrahepatic disorder. Since this virus is able to determine extrahepatic [non-Hodgkin's lymphoma(NHL)] as well as hepatic malignancies(hepatocellular carcinoma), HCV has been included among human cancer viruses. The most common histological types of HCV-associated NHL are the marginal zone, the lymphoplasmacytic and diffuse large cell lymphomas. The role of the HCV in the pathogenesis of the B-cell lymphoproliferative disorders is confirmed also by the responsiveness of the NHL to antiviral therapy. The purpose of this review is to provide an overview of the recent literature and a meta analysis of the epidemiology data, to explain the role of HCV in the development of NHL's lymphoma. Furthermore, the possibility to treat these HCV-related NHL with the antiviral therapy or with other therapeutic options, like chemotherapy, is also discussed.展开更多

High prevalence of NHL is documented in economically more developed areas while low prevalence is observed in less developed areas of the globe. A wide array of environmental factors have been reported to be either directly involved or in modifying the risk of NHL development. In addition to these factors, a number of infectious agents, chiefly viruses have also been implicated in the development of NHL. This article reviews the available literature to discuss the role of hepatitis viruses in NHL development, possible mechanisms of lymphomagenesis and also identify the areas in which further research is required to better understand this disease. A brief discussion on the clinical aspects such as classification, staging, treatment approaches have also been included in this article.展开更多

However, a proportion of patients do not respond to ASCT. lSF-fluorodeoxyglueose (FDG) positron emission tomography (PET)/computed tomography (CT) has been widely used for staging, response evaluation, and prognosis prediction. Here, we investigated the prognostic role of PET/CT in NHL patients before and after ASCT. Methods: A retrospective study was conducted at Peking University Cancer Hospital. All NHL patients who underwent ASCT between March 2010 and July 2016 were identified. Patients who had PET/CT scan before and after ASCT were included. Deauville criteria (5-point scale) were used to interpret PET scans. Univariate and multivariate survival analyses were performed using Cox regression. The predictive value of PET scanning was estimated by comparing the area under the receiver operating characteristic (ROC) curve. Results: In total, 79 patients were enrolled in this study. In univariate analysis, pre- and post-ASCT PET result was identified as prognostic factors for 3-year progression-free survival (PFS) and overall survival (OS). Patients with negative pre-ASCT PET result demonstrated significantly better PFS (84.2% vs. 54.2%) and OS (89.2% vs. 63.6%) than patients with positive pre-ASCT PET result. PFS (91.6% vs. 25.3%) and OS (96.5% vs. 36.8%) were also significantly different between patients with negative and positive post-ASCT PET result. Multivariate analysis also showed a significant association between survival and post-ASCT PET result. ROC analysis revealed that the predictive value of post-ASCT PET result was superior to that of pre-ASCT PET result alone. Combined pre- and post-ASCT PET result is better for predicting outcomes in patients with NHL receiving transplantation. Deauville criteria score 〉3 was identified as the best cutoffvalue for post-ASCT PET. Conclusions: Post-ASCT PET result was more important than pre-ASCT PET result in predicting outcomes for NHL patients who underwent ASCT. The prognostic significance can be improved when combining pre- ASCT PET result with post-ASCT PET result. Deauville criteria can be used for interpreting PET scans in this scenario.展开更多

To investigate the prognostic role of PD-L1 expression and the association between PD-L1 expression and clinicopathological features of NHL, we performed a meta-analysis.Methods: The Pub Med, EMBASE, and Cochrane Library databases were searched up to November 30, 2017. The hazard ratio(HR), 95% confidence interval(CI), and odds ratios(OR) with 95% CIs were combined to evaluate the association of PD-L1 expression with overall survival(OS) and clinicopathological features. Review manager 5.3 and STATA 12.0 were used in this meta-analysis.Results: A total of 2,005 patients across nine studies were enrolled in our meta-analysis, and the pooled results showed that high PD-L1 expression was associated with a poor prognosis(HR=2.04, 95% CI: 1.18–3.54, P=0.01). In the subgroup analysis according to histology types, pooled results demonstrated that an increased PD-L1 expression was an unfavorable prognostic factor for diffuse large B-cell lymphoma(HR=1.92, 95% CI: 1.06–3.48, P=0.03) but not for natural killer/T-cell lymphoma(HR=2.41, 95%CI: 0.47–12.22, P=0.29). Pooled ORs indicated that PD-L1 expression was higher in NHL with international prognostic indices of≥3. However, PD-L1 expression had no correlation with gender, age, disease stage, lactate dehydrogenase level, B symptoms, and germinal center B-cell-like lymphoma.Conclusions: High PD-L1 expression was a poor prognostic biomarker in patients with NHL. Because of our limited sample size,high-quality studies with larger sample sizes are needed to validate our results.展开更多

The results showed that the expression of survivin is significantly higher in aggressive NHL than in indolent NHL (P〈0.01), while there was no statistically significant difference between RH and indolent NHL (P〉0.05). The expres- sion of survivin had a significantly positive correlation with the expression of Ki-67 and FVSRAg (r=0.6495, 0.6635, respectively, both P〈0.01), and a negative correlation with the expression of caspase3 and AI (r=-0.5820, -0.6013, respectively, P〈0.01). It was suggested that survivin may contribute to the progression of NHL by playing an important role in promoting cell proliferation, inhibiting cell apoptosis and enlisting angiogenesis. Survivin expression is closely related to malignant grade and therefore may be considered an important prognostic factor of NHL.展开更多
文摘Background: Diffuse Large B-Cell Lymphoma (DLBCL) is the most variant of Non-Hodgkin’s Lymphoma (NHL) and also the most common variant with secondary intracardiac masses. Case summary: 7 years old child presented to emergency with acute decompensated cardiac failure, ascites and tender hepatomegaly. 2D echo evaluation was suggestive of large intracardiac mass in the right atrium almost completely obstructing Tricuspid valve orifice, gross pericardial effusion and dilated Inferior Vena Cava (IVC). Emergency tumor excision surgery was performed which revealed 4 × 4 cm pinkish firm mass arising from anterior Tricuspid annulus which was completely excised. Child was extubated on postoperative day (POD) 0 and was on minimal inotropic support. Ascites reduced significantly on POD1 allowing abdominal palpation which revealed a mass in the epigastric region. This prompted evaluation by pediatrician and oncology workup suggestive of increased 18-Flouro Deoxy Glucose (18-FDG) uptake in the mediastinum, abdomen, bilateral proximal thighs, all mediastinal lymph nodal stations, bilateral lung hilar stations 10R, 10L involving all encasing the heart and great vessels with pleural deposits, Celiac trunk, superior Mesenteric Artery (SMA), Portal vein, IVC and abdominal aorta. Histo pathology Examination (HPE) and Immuno Histo Chemistry (IHC) of intracardiac mass revealed DLBCL which is metastatic in nature. Chemotherapy was started as per (French American British Lymphomes Malins B) FAB LMB-96 protocol with the child currently in the Induction phase having poor prognosis and less survival interval. Conclusion: Surgery can be considered a treatment option for metastatic intracardiac masses during emergency scenarios like cardiogenic shock to relieve obstruction along the pathway of blood flow in the heart even though we may not be able to completely excise the tumor surgically.

文摘Reactivation of hepatitis B virus(HBV)can occur in lymphoma patients infected with HBV when they receive chemotherapy or immunotherapy.Prophylactic administration of lamivudine(LAM)reduces the morbidity and mortality associated with HBV reactivation.However,what defines HBV reactivation and the optimal duration of treatment with LAM have not yet been clearly established.HBV reactivation may occur due to the cessation of prophylactic LAM,although re-treatment with nucleoside analogs may sometimes result in hepatitis B surface antigen(HBsAg)seroconversion,which is a satisfactory endpoint for the management of HBV infection.We report a case of HBV reactivation in a 68-year-old HBsAg-positive patient who received rituximab-based immunochemotherapy for follicular lymphoma.HBV reactivation developed following cessation of prophylactic LAM therapy.The patient subsequently received treatment with entecavir(ETV),which led to a rapid and sustained suppression of HBV replication and HBsAg seroconversion.We also appraised the literature concerning HBV reactivation and the role of ETV in the management of HBV reactivation in lymphoma patients.A total of 28 cases of HBV reactivation have been reported as having been treated with ETV during or after immunosuppressive chemotherapy in lymphoma patients.We conclude that ETV is an efficacious and safe treatment for HBV reactivation following LAM cessation in lymphoma patients treated with rituximab-based immunochemotherapy.
文摘The hepatitis C virus(HCV) infected patients are prone to develop bone marrow or various tissue infiltrates with monoclonal B cells, monoclonal B lymphocytosis or different types of B cell non-Hodgkin's lymphoma(BCNHL), of which the most common are splenic marginal zone BCNHL, diffuse large BCNHL and follicular lymphoma. The association between chronic HCV infection and non Hodgkin's lymphoma has been observed especially in areas with high prevalence of this viral infection. Outside the limitations of some studies that have been conducted, there are also geographic, environmental, and genetic factors that contribute to the epidemiological differences. Various microenvironmental signals, such as cytokines, viral antigenic external stimulation of lymphocyte receptors by HCV antigens, and intercellular interactions contribute to B cell proliferation. HCV lymphotropism and chronic antigenic stimulation are involved in B-lymphocyte expansion, as mixted cryoglobulinemia or monoclonal gammopathy of undetermined significance, which can progress to BCNHL. HCV replication in B lymphocytes has oncogenic effect mediated by intracellular HCV proteins. It is also involved in an important induction of reactive oxygen species that can lead to permanent B lymphocyte damage, as DNA mutations, after binding to surface B-cell receptors. Posttransplant lymphoproliferative disorder could appear and it has a multiclonal potentiality that may develop into different types of lymphomas. The hematopoietic stem cell transplant made for lymphoma in HCV-infected patients can increase the risk of earlier progression to liver fibrosis and cirrhosis. HCV infected patients with indolent BCNHL who receive antiviral therapy can be potentially cured. Viral clearance was related to lymphoma response, fact that highlights the probable involvement of HCV in lymphomagenesis. Direct acting antiviral drugs could be a solution for the patients who did not tolerate or respond to interferon, as they seem to be safe and highly effective. The use of chemotherapy in combination with rituximab for the treatment of BCNHL in patients infected with HCV can produce liver dysfunction. The addition of immunotherapy with rituximab can increase the viral replication, and severe complications can occure especially in patients co-infected with hepatitis B virus or immune immunodeficiency virus, in those with hepatocarcinoma,cirrhosis, or liver cytolysis. But the final result of standard immunochemotherapy applied to diffuse large BCNHL patients with HCV infection is not notably worse than in those without this viral infection. The treatment of patients chronically infected with HCV and having BCNHL is complex and requires a multidisciplinary approach and the risk / benefit ratio of rituximab treatment must be evaluated especially in those with liver cytolysis.
文摘Primary non-Hodgkin’s lymphoma of the esophagus is a rare disease.A case of primary isolated nonHodgkin’s lymphoma of the esophagus in a 77-yearold man without acquired immunodeficiency syndrome is presented.We describe the clinical features and the imaging findings(barium swallow,endoscopic ultrasonography and CT)of a biopsy proven B-cell lymphoma with diffuse transmural involvement of the esophagus wall,which was discovered incidentally.We also briefly review the literature.
文摘AIM: To analyze the clinical features, management, and outcome of treatment of patients with primary intestinal and colonic non-Hodgkin's lymphoma (PICL).METHODS: A retrospective study was performed in 37 patients with early-stage PICL who were treated in our hospital from 1958 to 1998. Their clinical features,management, and outcome were assessed. Prognostic factors for survival were analyzed by univariate analysis using the Kaplan-Meier product-limit method and log-rank test.RESULTS: Twenty-five patients presented with Ann Arbor stage I PICL and 12 with Ann Arbor stage Ⅱ PICL. Thirty-five patients underwent surgery (including 31 with complete resection), 22 received postoperative chemotherapy or radiotherapy or both. Two patients with rectal tumors underwent biopsy and chemotherapy with or without radiotherapy. The 5- and 10-year overall survival (OS) rates were 51.9% and 44.5%. The corresponding diseasefree survival (DFS) rates were 42.4% and 37.7%. In univariate analysis, multiple-modality treatment was associated with a better DFS rate compared to single treatment (P = 0.001).While age, tumor size, tumor site, stage, histology, or extent of surgery were not associated with OS and DFS,use of adjuvant chemotherapy significantly improved DFS (P = 0.031) for the 31 patients who underwent complete resection. Additional radiotherapy combined with chemotherapy led to a longer survival than chemotherapy alone in six patients with gross residual disease after surgery or biopsy.CONCLUSION: Combined surgery and chemotherapy is recommended for treatment of patients with PICL.Additional radiotherapy is needed to improve the outcome of patients who have gross residual disease after surgery.

文摘Background: The regimen of cyclophosphamide, doxorubicin, vincristine, and prednisolone(CHOP) is an eicient treatment of non-Hodgkin's lymphoma(NHL). This study aimed to assess the eicacy and toxicity of dose-adjusted CHOP alone or in combination with rituximab(R-CHOP) by examining the stem cell mobilization in NHL patients. Factors afecting the collection of CD34+ cells were also explored.Methods: Our retrospective study included 39 patients eligible for autologous stem cell transplantation: 14 patients who expressed CD20 and were inancially eligible received R-CHOP for autologous peripheral blood stem cell(APBSC) mobilization; the remaining 25 patients received CHOP.Results: The median CD34+ cell yield was 7.01 × 106 cells/kg body weight(range 1.49–28.39 × 106 cells/kg body weight), with only two patients failing to meet the target CD34+ cell harvest of ber of apheresis procedures per patient was 1(range 1–3). The≥2.0 APBS× 106 cells/kg body weight. The median numC mobilization yield of the CHOP group appeared to be higher than that of the R-CHOP group(P response(CR) rate in = 0.005), whereas the success rate was similar between groups. R-CHOP elevated the completeB cell lymphoma patients as compared with CHOP(P = 0.01). No signiicant diferences in toxicity or engraftment were observed between the two groups.Conclusion: The present study demonstrated that dose-adjusted CHOP chemotherapy efectively mobilized APBSCs in NHL patients and that the addition of rituximab to dose-adjusted CHOP chemotherapy elevated the CR rate for patients with B-cell lymphoma.
文摘Primary malignant lymphoma of the prostate is exceedingly rare.Here we report a case of a 65-year-old man who presented with increased urinary frequency,urinary urgency,and urinary incontinence for two years.Benign prostatic hypertrophy was suspected at primary impression.Ultrasound revealed a hypoechoic lesion of the prostate.The total serum prostate-specific antigen was within normal range.Positron emission tomography/computerized tomography(PET/CT)showed a hypermetabolic prostatic lesion.Prostate biopsy was consistent with a non-germinal center diffuse large B cell lymphoma.There was complete remission of the prostatic lesion following six cycles of chemotherapy as shown on the second PET/CT imaging.18F-fluoro-deoxy glucose PET/CT is not only a complement to conventional imaging,but also plays a significant role in the diagnosis and evaluation of treatment response of prostatic lymphoma.

文摘Polymorphisms in DNA repair genes may alter DNA repair capacity and,consequently,lead to genetic instability and carcinogenesis.Several studies have investigated the association of the Asp312 Asn and Lys751 Gln polymorphisms in the xeroderma pigmentosum complementation group D {XPD) gene with the risk of non-Hodgkin's lymphoma(NHL),but the conclusions have been inconsistent.Therefore,we performed this meta-analysis to more precisely estimate these relationships.A systematic literature search was performed using the PubMed,Embase,and Chinese Biomedical(CBM) databases.Ultimately,6 studies of Asp312 Asn,comprising 3,095 cases and 3,306 controls,and 7studies of Lys751 Gln,consisting of 3,249 cases and 3,676 controls,were included.Pooled odds ratios(ORs) and 95%confidence intervals(CIs) were calculated to assess the strength of each association.Overall,no association was observed between the Asp312 Asn polymorphism and NHL risk(homozygous:OR = 1.11,95%CI = 0.94-1.32;heterozygous:OR = 1.00,95%CI = 0.89-1.11;recessive:OR = 1.12,95%CI = 0.95-1.31;dominant:OR = 1.02,95%CI = 0.92-1.13;and allele comparison:OR = 1.04,95%CI = 0.96-1.12) or between the Lys751 Gln polymorphism and NHL risk(homozygous:OR = 0.97,95%CI = 0.83-1.15;heterozygous:OR = 0.96,95%CI = 0.86-1.06;recessive:OR = 1.00,95%CI = 0.86-1.16;dominant:OR = 0.96,95%CI = 0.87-1.06;and allele comparison:OR = 0.98,95%CI = 0.91-1.05).Furthermore,subgroup analyses did not reveal any association between these polymorphisms and ethnicity,the source of the controls,or the NHL subtype.These results indicated that neither the Asp312 Asn nor Lys751 Gln XPD polymorphism was related to NHL risk.Large and well-designed prospective studies are required to confirm this finding.
文摘Balantidium coli is the only parasitic ciliate of man. It is a flattened oval organism covered with cilia, and a gullet at the anterior end. It is infrequently pathogenic for man,although epidemic buds in tropical zones have been described. The infection fundamentally affects the colon and causes variable clinic pictures, from asymptomatic to serious dysenteric forms. We present a case of parasitologically diagnosed as causes of diarrhea in a patient with non Hodgkin's lymphoma from Turkey.In order to find out the causative etiologic agent of diarrhea,stool samples were examined by native,lugol and flotation methods and we detected moving trophozoites, which were approximately 60μm long and 35μm wide.These bodies were diagnosed as Balantidium coli This case underlines that Balantidium coli should also be considered as a possible pathogen in immunocompromised patients with diarrhea.

文摘This study aims to examine the levels of circulating endothelial progenitor cells (cEPCs) in the peripheral blood of patients with non-Hodgkin lymphoma (NHL) and their correlation with the tumor stage. Forty-one patients with biopsy-proven NHL and 16 healthy individuals were recruited. Pe- ripheral blood mononuclear cells (PBMCs) were isolated by density gradient centrifugation, and cEPCs were characterized by triple staining using antibodies against CD133, CD34 and vascular endothelial growth factor receptor-2 (VEGFR-2, CD309) and quantified by flow cytometry. In NHL patients, the number of cEPCs was significantly greater than in control group (P=-0.000). The cEPCs counts in patients with NHL of stage III-1V were significantly greater than in stage I -II (P=-0.010). FACS analysis revealed that the number of cEPCs in NHL patients had no correlation with the gender (P=0.401) or the pathological category (P=0.852). It was suggested that the over-expression of cEPCs in NHL patients may serve as a novel biomarker for disease progression in NHL.

文摘To investigate the simultaneous occurrence of hepatocellular carcinoma and non-Hodgkin's lymphoma, we report the case of a 70 year old patient with a primary diagnosis of non-Hodgkin's lymphoma in 2002. In a routine follow up investigation of his chronic lymphocytic leukemia a newly detected mass in the Couinaud's segments 2 and 3 was found. No hepatitis C virus or hepatitis B virus infection or cirrhosis was evident. After laparoscopic segmentectomy the histological examination revealed a hepatocellular carcinoma. While the relation between liver parenchyma damages and hepatocellular carcinoma or non-Hodgkin's lymphoma is well known, only a few publications have focused on the coexistence of hepatocellular carcinoma and non-Hodgkin's lymphoma. With this case we demonstrate the coexistence of these diseases without having a pre- damaged liver parenchyma.
文摘Hepatitis C virus(HCV) is a global health problem affecting a large fraction of the world's population: This virus is able to determine both hepatic and extrahepatic diseases. Mixed cryoglobulinemia, a B-cell "benign" lymphoproliferative disorders, represents the most closely related as well as the most investigated HCVrelated extrahepatic disorder. Since this virus is able to determine extrahepatic [non-Hodgkin's lymphoma(NHL)] as well as hepatic malignancies(hepatocellular carcinoma), HCV has been included among human cancer viruses. The most common histological types of HCV-associated NHL are the marginal zone, the lymphoplasmacytic and diffuse large cell lymphomas. The role of the HCV in the pathogenesis of the B-cell lymphoproliferative disorders is confirmed also by the responsiveness of the NHL to antiviral therapy. The purpose of this review is to provide an overview of the recent literature and a meta analysis of the epidemiology data, to explain the role of HCV in the development of NHL's lymphoma. Furthermore, the possibility to treat these HCV-related NHL with the antiviral therapy or with other therapeutic options, like chemotherapy, is also discussed.
文摘Non-Hodgkin's lymphoma(NHL) is among the haematological malignancies with high prevalence worldwide, causing estimated 355 900 new cases and 191 400 deaths in 2008. High prevalence of NHL is documented in economically more developed areas while low prevalence is observed in less developed areas of the globe. A wide array of environmental factors have been reported to be either directly involved or in modifying the risk of NHL development. In addition to these factors, a number of infectious agents, chiefly viruses have also been implicated in the development of NHL. This article reviews the available literature to discuss the role of hepatitis viruses in NHL development, possible mechanisms of lymphomagenesis and also identify the areas in which further research is required to better understand this disease. A brief discussion on the clinical aspects such as classification, staging, treatment approaches have also been included in this article.

文摘Objective: High-dose chemotherapy (HDC) followed by autologous stem cell transplantation (ASCT) is the standard of care in the upfront or relapsed/refractory setting in some patients with non-Hodgkin lymphoma (NHL). However, a proportion of patients do not respond to ASCT. lSF-fluorodeoxyglueose (FDG) positron emission tomography (PET)/computed tomography (CT) has been widely used for staging, response evaluation, and prognosis prediction. Here, we investigated the prognostic role of PET/CT in NHL patients before and after ASCT. Methods: A retrospective study was conducted at Peking University Cancer Hospital. All NHL patients who underwent ASCT between March 2010 and July 2016 were identified. Patients who had PET/CT scan before and after ASCT were included. Deauville criteria (5-point scale) were used to interpret PET scans. Univariate and multivariate survival analyses were performed using Cox regression. The predictive value of PET scanning was estimated by comparing the area under the receiver operating characteristic (ROC) curve. Results: In total, 79 patients were enrolled in this study. In univariate analysis, pre- and post-ASCT PET result was identified as prognostic factors for 3-year progression-free survival (PFS) and overall survival (OS). Patients with negative pre-ASCT PET result demonstrated significantly better PFS (84.2% vs. 54.2%) and OS (89.2% vs. 63.6%) than patients with positive pre-ASCT PET result. PFS (91.6% vs. 25.3%) and OS (96.5% vs. 36.8%) were also significantly different between patients with negative and positive post-ASCT PET result. Multivariate analysis also showed a significant association between survival and post-ASCT PET result. ROC analysis revealed that the predictive value of post-ASCT PET result was superior to that of pre-ASCT PET result alone. Combined pre- and post-ASCT PET result is better for predicting outcomes in patients with NHL receiving transplantation. Deauville criteria score 〉3 was identified as the best cutoffvalue for post-ASCT PET. Conclusions: Post-ASCT PET result was more important than pre-ASCT PET result in predicting outcomes for NHL patients who underwent ASCT. The prognostic significance can be improved when combining pre- ASCT PET result with post-ASCT PET result. Deauville criteria can be used for interpreting PET scans in this scenario.

文摘Objective: Although the prognostic value of programmed cell death-ligand 1(PD-L1) expression in non-Hodgkin lymphoma(NHL) has been evaluated in many studies, the results remain controversial. To investigate the prognostic role of PD-L1 expression and the association between PD-L1 expression and clinicopathological features of NHL, we performed a meta-analysis.Methods: The Pub Med, EMBASE, and Cochrane Library databases were searched up to November 30, 2017. The hazard ratio(HR), 95% confidence interval(CI), and odds ratios(OR) with 95% CIs were combined to evaluate the association of PD-L1 expression with overall survival(OS) and clinicopathological features. Review manager 5.3 and STATA 12.0 were used in this meta-analysis.Results: A total of 2,005 patients across nine studies were enrolled in our meta-analysis, and the pooled results showed that high PD-L1 expression was associated with a poor prognosis(HR=2.04, 95% CI: 1.18–3.54, P=0.01). In the subgroup analysis according to histology types, pooled results demonstrated that an increased PD-L1 expression was an unfavorable prognostic factor for diffuse large B-cell lymphoma(HR=1.92, 95% CI: 1.06–3.48, P=0.03) but not for natural killer/T-cell lymphoma(HR=2.41, 95%CI: 0.47–12.22, P=0.29). Pooled ORs indicated that PD-L1 expression was higher in NHL with international prognostic indices of≥3. However, PD-L1 expression had no correlation with gender, age, disease stage, lactate dehydrogenase level, B symptoms, and germinal center B-cell-like lymphoma.Conclusions: High PD-L1 expression was a poor prognostic biomarker in patients with NHL. Because of our limited sample size,high-quality studies with larger sample sizes are needed to validate our results.
文摘In order to investigate the expression change of survivin in non-Hodgkin lymphoma (NHL) and its possible effects on NHL development, the expression of survivin, Ki-67, caspase3 and FⅧRAg in reactive lymphoid hyperplasia (RH) and NHL was detected by immunohistochemical assay, and apoptosis index (AI) in RH and NHL by TUNEL analysis. The results showed that the expression of survivin is significantly higher in aggressive NHL than in indolent NHL (P〈0.01), while there was no statistically significant difference between RH and indolent NHL (P〉0.05). The expres- sion of survivin had a significantly positive correlation with the expression of Ki-67 and FVSRAg (r=0.6495, 0.6635, respectively, both P〈0.01), and a negative correlation with the expression of caspase3 and AI (r=-0.5820, -0.6013, respectively, P〈0.01). It was suggested that survivin may contribute to the progression of NHL by playing an important role in promoting cell proliferation, inhibiting cell apoptosis and enlisting angiogenesis. Survivin expression is closely related to malignant grade and therefore may be considered an important prognostic factor of NHL.
