Primary mediastinal B-cell lymphoma (PMBL) is characterized by aberrant activation of JAK/STAT-signaling resulting in constitutive presence of phosphorylated STAT6 (pSTAT6). identified five STAT-binding-sites in the promoter. We confirmed STAT6 binding to the promoter and by band shift / super shift assays and chromatin immunoprecipitationsUsing luciferase reporter assays, depletion of STAT6 by siRNA, and ectopic overexpression of a constitutive active STAT6 mutant, we proved that pSTAT6 is sufficient to transcriptionally KLF5 repress BCL6. Recently developed small molecule inhibitors 79-6 and TG101348 that increases BCL6 target gene expression and decreases pSTAT6 levels, respectively, demonstrate that a combined targeting results in additive efficacy regarding their negative effect on cell viability. The delineated pSTAT6-mediated molecular repression mechanism links JAK/STAT to BCL6-signaling in PMBL and may carry therapeutic potential. amplifications that established PMBL as a genetically ...
The US Food and Drug Administration has​ approved the medicine Keytruda for the treatment of Primary mediastinal large B-cell lymphoma (PMBCL).
Primary Mediastinal B-Cell Lymphoma (or PMBCL for short), is a very rare form of cancer. At this point, I think I have found and read every article or scientific study written about PMBCL. There are not that many in fact, as it was only designated as its own entity in 2008 (prior to this it…

A dose-adjusted, infusion approach to aggressive chemotherapy with Rituxan® (rituximab) may allow patients with primary mediastinal B-cell lymphoma to skip radiation, according to the results of a study published in the New England Journal of Medicine.. Non-Hodgkins lymphoma (NHL) refers to a group of cancers that originate in different cells of the immune system. Diffuse large B-cell NHL (DLBCL) is a common type of NHL that affects immune cells called B-cells; it is considered an aggressive type of NHL. Primary mediastinal B-cell lymphoma is a distinct subtype of DLBCL that is closely related to nodular sclerosing Hodgkins lymphoma. Patients are usually young and present with large mediastinal masses. There is no standard treatment-and because immunochemotherapy alone has proven inadequate, some patients are treated with consolodiation with radiation, which has potentially serious late effects.. In an attempt to improve cure rates and prevent the need for radiation in this population, ...
TY - JOUR. T1 - CT of posterior mediastinal masses.. AU - Kawashima, Akira. AU - Fishman, E. K.. AU - Kuhlman, J. E.. AU - Nixon, M. S.. PY - 1991/1/1. Y1 - 1991/1/1. N2 - This article presents an algorithmic approach to the evaluation of posterior mediastinal masses seen with computed tomography (CT). CT remains the study of choice, since it not only can be used to help confirm the presence of these masses, but it also helps define the (a) location and extent of the lesion, (b) adjacent organ involvement, or (c) vascular involvement. Causes of posterior mediastinal masses include esophageal lesions, congenital or acquired vascular lesions, foregut cysts, intrathoracic goiters, mediastinal pseudocysts, fat-containing tumors, adenopathy, neurogenic tumors, infectious spondylitis, and vertebral tumors. From the CT appearance of the lesion, one can often distinguish among the various masses and identify their origin and cause. This information enables patient triage and therapy to be expedited and, ...
While NFKBIE deletions were relatively rare in patients diagnosed with follicular lymphoma (3/225 [1.3%]), splenic marginal zone lymphoma (3/175 [1.7%]), and T-cell acute lymphoblastic leukemia (1/94 [1.1%]), slightly higher frequencies were detected among DLBCL (18/520 [3.5%]), mantle cell lymphoma (8/189 [4.2%]), primary central nervous system lymphoma (1/34 [2.9%]), and small lymphocytic lymphoma (1/9 [11.1%]). In contrast, PMBL patients showed a marked enrichment, with 46 of 203 cases harboring a NFKBIE deletion (22.7% vs 2.9% [38/1257 in other entities]; P , .001; Figure 1A). Notably, the prevalence of NFKBIE-deleted PMBL cases was independent of contributing center (supplemental Table 3).. In an ongoing exome sequencing analysis of microdissected HRS cells in cHL, we obtained indication for NFKBIE mutations in 4 out of 11 cases. From these 4 cases, we isolated HRS cells and confirmed somatic NFKBIE aberrations (1 deletion and 2 missense mutations) in 3 out of 4 cases by Sanger sequencing ...

Yogi Berra offered the comment Its déjà vu all over again when he witnessed Mickey Mantle and Roger Maris repeatedly hitting back-to-back home runs in the early 1960s. His pithy remark neatly summarizes my reaction when I read the article, Dose-Adjusted EPOCH-Rituximab Therapy in Primary Mediastinal B-Cell Lymphoma, by Drs. Dunleavy, Wilson, and colleagues in The New England Journal of Medicine.1. The report nicely caps more than a decade of clinical investigation carried out by Dr. Wilsons group at the National Cancer Institute, focused on the use of infusional immunochemotherapy to treat various aggressive non-Hodgkin lymphomas (see a summary of the report in this issue of The ASCO Post). Briefly, this group demonstrated that when they used dose-adjusted EPOCH-R (etoposide, prednisone, vincristine, cyclophosphamide, doxorubicin, and rituximab [Rituxan]) to treat primary mediastinal large B-cell lymphoma in 51 patients, almost all of the patients appeared to have been cured. ...
Diffuse large B cell lymphoma (DLBCL) is the most common histologic subtype of non-Hodgkin lymphoma (NHL), accounting for approximately 25 percent of adult NHL cases. (See.)The molecular pathogenesis of DLBCL is a complex, multistep process that ulti
The management of diffuse large B-cell lymphoma (DLBCL) has been gradually evolving since the discovery of its 2 major forms, the germinal center B-like (GCB) and activated B-cell (ABC) types. Although the reference standard for the identification of these cell types is considered gene expression profiling (GEP), currently the only method commercially available is immunohistochemistry (IHC). The application of various IHC-based algorithms and their correlation with GEP and clinical outcome are discussed. Because of the adverse prognostic implications of the non-GCB type and its potential effects on treatment selection, the recently revised World Health Organization classification has included these biologic cell types ...
The present study retrospectively examined the diagnostic utility of adding positron emission tomography (PET) or magnetic resonance imaging (MRI) to computed tomography (CT) alone for preoperative diagnosis of anterior mediastinal tumors. A total of 104 consecutive patients who had undergone surgical resection of anterior mediastinal tumors were divided into two groups: Additional PET to another modality and no additional PET to another modality, and further subdivided into three groups: CT alone, additional MRI to CT and additional PET to CT. The sensitivity, specificity, and accuracy for diagnosing malignant tumors in each subgroup was calculated. Comparing the two groups, the diagnostic sensitivity was similar for additional PET (98.0%) and no additional PET (95.2%) groups; however, the specificity and accuracy for additional PET (75.0 and 92.2%, respectively) were significantly improved compared with no additional PET (31.6 and 65.0%, respectively). In the subgroup analysis, adding PET to ...
Massive hemoptysis is described in many disease processes. However, a mediastinal teratoma is rarely considered in a patient presenting with massive hemoptysis. Since a mediastinal teratoma has no specific symptoms, its definitive diagnosis is difficult before surgical intervention. Flexible bronchoscopy can be diagnostic in cases of a mediastinal teratoma with involvement of the bronchial tree. We report 2 cases of hemoptysis caused by mediastinal teratoma with bronchial communication. ...
Recently, copy number alteration (CNA) of 9p24.1 were demonstrated in 10% of diffuse large b-cell lymphoma (DLBCL), with gene expression and mutation profiles that were similar to those of primary mediastinal large B-cell lymphoma (PMBCL). However, their CNA-based profile and clinical impact still remain unclear. Multiplex ligation-dependent probe amplification were employed to investigate the prevalence of JAK2/PD-L2 amplification in DLBCL and their CNA-based pattern of driver genes. The clinical outcome and characteristics were also analyzed. Using unsupervised hierarchical clustering, a small group of DLBCL (10.5%, 8/76) was clustered together with PMBCL as Cluster_2, demonstrating amplification of JAK2 (100%,8/8) and PD-L2 (75.0%,6/8). This subgroups of DLBCL demonstrated significant higher expression of PD-L1 than those with MYD88 L265P mutation(p = 0.024). And they exhibited dismal OS and PFS as compared with DLBCL_others(p = 0.003 and 0.001, respectively), which is similar to DLBCL with MYD88

AU - Ferreri, Andrés J M. PY - 2013/5. Y1 - 2013/5. N2 - Within diffuse large B-cell lymphomas, the Primary Mediastinal Large B-Cell Lymphoma has to be considered as a separate and well-defined clinico-pathological entity. Its tendency to target young adults makes its social impact particularly significant; hence, the General Practitioner carries the responsibility for an early diagnosis. On the contrary, the extreme complexity of the available therapies makes a quick referral to specialized Clinical Centres of outmost importance, since this remains the best way to enrol as many patients as possible in therapeutic protocols. Nowadays, good clinical results and a favourable outcome are achievable, but some questions remain open. The role of radiotherapy still has to be clarified, both as a complete ...

Aims: Patients presenting with a neck mass are commonly seen by the ENT surgeon. They are also usually related to head and neck tumours. However, cervical node involvement from the prostate is rare, especially as an initial presentation of the disease. We report a case of prostate carcinoma presenting with a left supraclavicular lymph node.. Presentation of Case: A 61-year-old gentleman presented to our clinic with a rapidly growing left sided neck mass. Fine needle aspiration cytology (FNAC) of the neck mass was interpreted as metastatic carcinoma. It was later revealed by the patient that he had been experiencing lower urinary tract symptoms (LUTS). PSA was 1331 ng/ml. He was referred to our urology service and was treated as metastatic prostate cancer.. Discussion: Prostate cancer commonly spreads to the regional lymph nodes, pelvic organs, or the axial skeleton. Distant metastases to the cervical nodes are rare and accounts for 0.3-1% of cases.. Conclusion: In male patients presenting with ...

A multicentric study of lung cancer staged by PET-TC and EBUS-NA was performed to identify PET-TC measures with high positive predictive value (PPV) for the identification of stage III disease and to evaluate EBUS-NA sensitivity. A surgical gold standard was used when EBUS-NA was negative.. Results: 76/105 patients showed ≥1 hypermetabolic spot in mediastinum (72%). PET-TC SUVmax did not show statistically significant differences between centers. Lung SUVmax had mean of 11.4 (SD 5.3), and hypermetabolic spot in mediastinum median of 3.4 (IQR 0-6.5). EBUS-NA confirmed mediastinal metastasis in 43/54 patients (79.6%). A single hypermetabolic image in mediastinum was not a significant predictor of dissemination (OR 1.99 95%CI 0.75-5.32), but ≥2 hypermetabolic spots showed an increased risk (OR 3.64 95%CI 1.29-10.26). Lung SUVmax was not associated with mediastinal malignancy (OR 0.93 95%CI 0.86-1.01), but mediastinum SUVmax ,3.4 was a significant predictor (OR 6,36 95%CI 2,71-14,91), that ...

BACKGROUND: Mediastinal and central large vessels (T4) invasion by lung cancer is often difficult to assess preoperatively due to the limited accuracy of computed tomography (CT) scan of the chest. Esophageal ultrasound (EUS) can visualize the relationship of para-esophageally located lung tumors to surrounding mediastinal structures. AIM: To assess the value of EUS for detecting mediastinal invasion (T4) of centrally located lung tumors. METHODS: Patients who underwent EUS for the diagnosis and staging of lung cancer and in whom the primary tumor was detected by EUS and who subsequently underwent surgical- pathological staging (2000-2016) were retrospectively selected from two university hospitals in The Netherlands ...

Sattva S. Neelapu, M.D., from the University of Texas MD Anderson Cancer Center in Houston, and colleagues enrolled 111 patients with diffuse large B-cell lymphoma, primary mediastinal B-cell lymphoma, or transformed follicular lymphoma with refractory disease despite receiving prior therapy. A target dose of 2×106 anti-CD19 CAR T cells/kg body weight was administered to 101 patients. The researchers found that the objective and complete response rates were 82 and 54 percent, respectively. Overall, 42 percent of the patients continued to have a ...
Chimeric antigen receptor T-cells are a novel class of anti-cancer therapy in which autologous or allogeneic T-cells are engineered to express a chimeric antigen receptor targeting a membrane antigen. In Europe, Tisagenlecleucel (KymriahTM) is approved for the treatment of refractory/relapsed Acute Lymphoblastic Leukaemia in children and young adults as well as relapsed/refractory Diffuse Large B-cell Lymphoma; Axicabtagene ciloleucel (YescartaTM) is approved for the treatment of relapsed/refractory high-grade B-cell Lymphoma and Primary Mediastinal B-cell Lymphoma. Both agents are genetically engineered autologous T-cells targeting CD19. These practical recommendations, prepared under the auspices of the European Society of Blood and Marrow Transplantation, relate to patient care and supply chain management under the following headings: patient eligibility, screening laboratory tests and imaging and work-up prior to leukapheresis, how to perform leukapheresis, bridging therapy, lymphodepleting ...
Mediastinal lymphoma in dogs usually develops in the lymphoid tissues of the chest. They are present around the cardiothoracic region. If left untreated, they can restrict the function of lungs, resulting in death.. Symptoms- This form of lymphoma comprises only a fraction of all cases of lymphosarcomas. It is typically characterized by enlargement of the cranial mediastinal lymph nodes, thymus, or both. Dogs suffering from mediastinal lymphoma encounter respiratory distress, polydipsia, polyuria, pitting edema of the head, necks and forelimbs.. Cutaneous lymphoma- It originates in the skin and can take the form of reddened lumps that can be itchy at times and also cause extreme discomfiture in dogs.. Symptoms- They appear as ulcers, nodules, plaques, ulcers, and erythremic or exfoliative dermatitis. In the early phases scaling, alopecia (loss of hair), and pruritus (itching) are seen. As the disease advances the skin becomes more erythematous, thickened, ulcerated, and exudative (relating to ...

For patients with a possible mediastinal mass, the first step is to obtain a chest radiograph. Following the chest radiograph, a CT can help to further delineate the features of the tumor. Additional workup could include: echocardiogram and pulmonary function tests [1,3,4]. Ultimately, tissue diagnosis will be necessary. There is no ideal anesthetic technique for a patient with AMM, as any technique can be associated with morbidity and mortality. However, the overall anesthetic goals should include: maintenance of spontaneous ventilation, coordination of appropriate equipment for airway and cardiac support, and ensuring availability of emergency team members [2]. Based on the presence or absence of respiratory symptoms, degree of tracheal compression, mediastinal mass ratio and other factors, patients may be classified as being at high or low risk (Figure 3). A low risk patient, who does not have any respiratory symptoms or tracheal compression by CT, may proceed with a general anesthetic. ...
The posterior mediastinum is the portion of the mediastinum located posteriorly to the pericardium and anteriorly to the T5-T12 vertebrae, inferior to the transverse thoracic plane. This article will consider the borders and contents of this anatomical compartment.

Germ cell tumors of the mediastinum are uncommon. Less than 5-7% of germ cells occur outside the gonads, but of the extragonadal sites, the mediastinum is the most common location for germ cell tumors.
Hi…this is my first time to participate in your intesting blog,…and here is what i see:. The right lower lung zone show relatively well defined radiopacity seen with well defined upper border and showing negative silhuoette sign with the right cardiac border, also it is seen at the lateral film projected over the right loer lung zone and with well defined anterior superior border and with relatively obtuse angle with the plueral surface (extra pulmonary) and seprable from the hemidiaphragm….so it is wither of plueral origin ( answer 2) or a posterior mediastinal mass ( may be of spinal) or posterior chest wall ...

N2 - Radiation-induced coronary heart disease (RICHD) is the second most common cause of morbidity and mortality in patients treated with radiotherapy for breast cancer, Hodgkins lymphoma and other prevalent mediastinal malignancies. The risk of RICHD increases with radiation dose. Exposed patients may present decades after treatment with manifestations ranging from asymptomatic myocardial perfusion defects to ostial, triple-vessel disease and sudden cardiac death. RICHD is insidious, with a long latency and a tendency to remain silent late into the disease course. Vessel involvement is often diffuse and is preferentially proximal. The pathophysiology is similar to that of accelerated atherosclerosis, characterised by the formation of ...
