Central nervous system lymphoma is a rare non-Hodgkin lymphoma in which malignant (cancer) cells from lymph tissue form in the brain and/or spinal cord (primary CNS) or spread from other parts of the body to the brain and/or spinal cord (secondary CNS). Because the eye is so close to the brain, primary CNS lymphoma can also start in the eye (called ocular lymphoma). The cancer can also involve the spinal fluid that bathes the spinal cord and brain. This is called leptomeningeal lymphoma. See Primary Central Nervous System Lymphoma for signs, symptoms and treatments.. ...

AU - Hirose, Takanori. PY - 2017/1/1. Y1 - 2017/1/1. N2 - Primary CNS lymphoma (PCNSL) is a rare diffuse large B-cell lymphoma originating within the central nervous system. The overall incidence of PCNSL is rising, particularly in the elderly population. Immunosuppression is a strong risk factor, but most patients with this tumor are apparently immunocompetent. Diagnosis of PCNSL can be challenging. Non-invasive or minimally invasive tests such as ophthalmological evaluation and spinal fluid analysis may be useful, but the majority of patients require tumor biopsy for definitive diagnosis. Our knowledge concerning optimum treatment of PCNSL is fragmentary due to paucity of adequately sized trials. Most patients are now initially treated with high-dose-methotrexate-based chemotherapy alone, as the ...
Primary central nervous system lymphoma(PCNSL) is a rare kind of non-Hodgkin lymphoma. Rituximab combined with high-dose methotrexate, cytarabine and dexamethasone (R-MAD regimen) were reported effective for PCNSL patients. Rituximab can cause several side effects, including fever, chills and rigors. In this case report, we demonstrate rituximab-induced interstitial pneumonitis in a PCNSL patient who has been treated with R-MAD regimen. The patient recovered after treatment and she remains complete remission after following consolidation chemotherapy. Here is no report of potential fatal complications of Rituximab like interstitial pneumonitis nowadays in PCNSL patients. As Rituximab is widely used, physicians should raise their awareness of this rare complication and detect RTX-ILD in early stage.
This study will evaluate the usefulness of two tests in quickly distinguishing whether a patient with HIV infection and focal brain lesions (an injury in a specific area of the brain) has a rare type of cancer called primary central nervous system lymphoma (PCNSL), or a parasitic infection called toxoplasmic encephalitis.. Toxoplasmic encephalitis is caused by a parasite and can be treated with antibiotics. PCNSL (lymphoma of the brain or spinal cord) must be definitively diagnosed with a brain biopsy (removal of a small piece of brain tissue), and the treatment is radiation therapy and chemotherapy.. The tests under study for diagnosing PCNSL or toxoplasmic encephalitis are measurement of Epstein Barr virus (EBV) DNA in cerebrospinal fluid (CSF) and FDG-PET scan of the brain. EBV is often found in the CSF of people with PCNSL. The study also will compare the accuracy of two imaging techniques-TI-SPECT and FDG-PET-in distinguishing between toxoplasmosis and PCNSL.. Patients 18 years of age and ...
The initial intent of this study was to examine the origins of Primary Central Nervous System Lymphoma (PCNSL), a neoplasm whose oncogenesisin immunocompetentpatients is incompletely understood. With growing information regarding the remarkable plasticity of neural stem cells, and establishment of relationships between hematopoietic and neural stem cells, we hypothesized that PCNSL arises from neural stem/progenitor cells rather than lymphocyte precursors from elsewhere in the body. Markers of neural stem cells were chosen for immunohistochemical(IHC) staining of 5 PCNSL cases and all cases contained Sox2 positive cells, whereas 8 of 9 non-CNS B cell lymphomas so stained had no positive cells. Double-staining with Sox2 and CD20, a B-cell marker, showed no co-localization of Sox2 and CD20, and no CD20-positive tumor cells had Sox2 immunopositivity. Staining of 5 metastatic carcinomas and 1 metastatic melanoma revealed a similar pattern of immunopositivityboth regarding sox2 expression and ...
Paraffin sections of surgical and autopsy material from 24 cases of primary CNS lymphoma were examined for the presence of cytoplasmic immunoglobulin by an immunoperoxidase technique. Definite staining for cytoplasmic immunoglobulin was observed in 13 cases, and in eight of these the pattern of staining was consistent with current concepts of monoclonality. In every case the histological diagnosis of malignant lymphoma was confirmed, and cases were subclassified by both the Lukes-Collins and the Rappaport classifications. Morphologically 12 of the 24 cases resembled immunoblastic sarcoma occurring outside the CNS. Other cases showed features of follicular center cell lymphoma or plasmacytoid lymphocytic lymphoma. Of those cases with positive immunoglobulin staining of tumor cells, the majority showed some plasmacytoid features. It was concluded that the primary CNS lymphomas resemble their counterparts occurring outside the CNS, and that at least a proportion are derived from the B lymphocyte. ...

Population pharmacokinetics of high-dose methotrexate in patients with primary central nervous system lymphoma | A Smarter Pharmacy
Each cell in HIV-associated primary central nervous system lymphoma (PCNSL) harbors latent EBV. Notably, the triggering of TLR9, a key event in HIV pathogenesis, also promotes EBV latency and transformation. We hypothesized that because only a minority of HIV-infected patients develops PCNSL, their B cells exhibit aberrant signaling responses to TLR9 triggering. We found higher levels of IL-6, CD80, and CD86 expression at baseline in B cells of those patients than in B cells of matched controls, whereas TNF-a expression was lower. Notably, on TLR9 triggering with CpG 2006, CD80 and TNF- were up-regulated to a lesser extent in B cells of the former than in those of matched controls. The reduced up-regulation of CD80 might be explained by its higher baseline expression resulting in a more blunted response rather than a specific deficit of the signaling response to TLR9 triggering. However, this cannot explain the blunted TNF- response, which warrants further investigation. Finally, since increased ...

Our study, which is the first large scale population based assessment of lymphoma characteristics in coeliac disease, has demonstrated that the association between coeliac disease and malignant lymphomas is not confined to ETTL but includes other types of T cell NHLs and, more importantly, B cell NHLs that constitute the vast majority of malignant lymphomas in the general population. Indeed, ETTL cases comprised only one third of NHL cases and half of all T cell lymphomas in our study, values markedly lower than previously reported.4-8,24 Furthermore, with respect to location, our study indicated that the association was not confined to primary gastrointestinal lymphomas but also included malignant lymphomas outside of the gastrointestinal tract of both the B and T cell phenotype. Few previous studies have classified coeliac disease associated malignant lymphomas using modern immunostaining methods.7,8,11 In one of these, 23 of 24 reviewed cases were ETTL.8 In another, 11 of 13 lymphomas were of ...
The cell of origin of lymphomas arising in the CNS, a site devoid of normal resident lymphoid tissue, has not been determined. Morphological (4) , immunophenotypic (4) , and molecular genetic (5) studies of PCNSL suggest that the cell of origin is related to the GC. Expression of BCL-6 is one feature that suggests a relationship to the GC. The BCL-6 protein is a zinc-finger transcriptional repressor encoded by the BCL-6 gene (12) . It is required for the formation of the GC (13) . In normal lymphoid tissue, there is nuclear expression of the BCL-6 protein almost exclusively by GC B cells. Lymphomas thought to be derived from GC cells, such as follicular lymphoma, also express BCL-6, whereas lymphomas derived from naïve (chronic lymphocytic leukemia and mantle cell lymphoma) or post-GC (marginal zone lymphomas, myeloma) B cells do not (14 , 15) .. Additional immunophenotypic markers that can aid in the characterization of lymphoid cells with respect to stage of B-cell differentiation were ...

Non-Hodgkins lymphoma (or NHL) is one of the most common cancers among 9/11 responders and survivors. Turley Hansen has represented many claimants with Non-Hodgkin lymphoma since cancer was added to the list of illnesses covered under the Zadroga Act.. Non-Hodgkins lymphoma, also called non-Hodgkins lymphoma or NHL, is a cancer that originates in your lymph system - the network spread throughout your body to fight diseases. In non-Hodgkins lymphoma, tumors develop from lymphocytes - a type of white blood cell.. Non-Hodgkins lymphoma is more common than the other general type of lymphoma - Hodgkins lymphoma. Many different sub-types of non-Hodgkins lymphoma exist. The most common non-Hodgkins lymphoma sub-types include diffuse large B-cell lymphoma and follicular lymphoma.. ...
AIDS-related lymphoma describes lymphomas occurring in patients with acquired immunodeficiency syndrome (AIDS). A lymphoma is a type of cancer arising from lymphoid cells. In AIDS, the incidences of non-Hodgkins lymphoma, primary cerebral lymphoma and Hodgkins disease are all increased. There are three different varieties of AIDS-related lymphoma: Diffuse large B-cell lymphoma, B-cell immunoblastic lymphoma, and Burkitts lymphoma (small non-cleaved cell lymphoma). The symptoms of AIDS-related lymphoma can include: weight loss, fever, and night sweats. Non-Hodgkins lymphoma (NHL) is present in about 1%-3% of HIV seropositive people at the time of the initial diagnosis of HIV. However, it is believed that such patients have been seropositive for a prolonged period, but have simply not had their infections recognized previously. This is so because immunodysregulation must exist for an extended interval of time, in order for a lymphoproliferative process to evolve in that context. Primary ...
Both Hodgkins lymphoma and non-Hodgkins lymphoma are lymphomas - a type of cancer that begins in a subset of white blood cells called lymphocytes. Lymphocytes are an integral part of your immune system, which protects you from germs.. The main difference between Hodgkins lymphoma and non-Hodgkins lymphoma is in the specific lymphocyte each involves.. A doctor can tell the difference between Hodgkins lymphoma and non-Hodgkins lymphoma by examining the cancer cells under a microscope. If in examining the cells, the doctor detects the presence of a specific type of abnormal cell called a Reed-Sternberg cell, the lymphoma is classified as Hodgkins. If the Reed-Sternberg cell is not present, the lymphoma is classified as non-Hodgkins.. Many subtypes of lymphoma exist, and your doctor will use laboratory tests to examine a sample of your lymphoma cells to determine your specific subtype. Expect to wait a few days to receive results from these specialized tests.. Your type of lymphoma helps ...
Follicular lymphoma is the most common form of low-grade NHL and the second most common type of lymphoma overall diagnosed in the United States. Most follicular lymphoma diagnoses occur in adults over the age of 60, with equal rates of occurrence in male and female individuals; this specific lymphoma is rare in young people.. Follicular lymphoma affects B-cell lymphocytes and is indolent, which means it grows very slowly. Like most lymphomas, follicular lymphoma usually begins in the lymph nodes. The cells can spread into the blood and bone marrow. Other internal organs, including the liver and spleen, may also be affected.. Because follicular lymphoma grows so slowly, doctors may not treat it right away and instead adopt a watchful waiting approach. Over time, some follicular lymphomas transform into an aggressive (fast-growing) diffuse B-cell type of lymphoma, so its important for people with follicular lymphoma to be monitored closely. Learn more about the several treatment options that ...

Response:. Our group published a microarray study of primary central nervous system lymphoma (PCNSL) in Blood in March 2008.1 We reported a comprehensive CNS signature of PCNSL, identifying single-gene differential expression as well as a pathway signature. Most notably, our pathway signature for PCNSL is characterized by differential expression of extracellular matrix (ECM)- and adhesion-related pathways. The most up-regulated gene is the ECM- and adhesion-related osteopontin (SPP1). Our study is unique in that we compared PCNSL to a broad spectrum of non-CNS diffuse large B-cell lymphoma (DLBCL), consisting of nodal and extranodal samples; and in-depth bioinformatics analysis was performed. This is in contrast to 2 other microarray studies in PCNSL2,3 in which the comparisons were made to nodal DLBCL and no pathway analysis was performed.. We are pleased that Rubenstein et al have confirmed our single-gene expression findings by retrospective analysis of their data and come up with concordant ...
Lymphomas account for 5% of all cancers in the United States, with Non-Hodgkins lymphoma being far more prevalent than Hodgkins lymphoma. It is estimated that in 2012, 70,130 will be diagnosed with Non-Hodgkins lymphoma and 9,060 will be diagnosed with Hodgkins lymphoma. Further, it is estimated that 18,940 people will die from Non-Hodgkins lymphoma and 1,190 people will die from Hodgkins lymphoma this year. One out of every 47 people will be diagnosed with Non-Hodgkins lymphoma and one out of every 436 people will be diagnosed with Hodgkins lymphoma in their lifetimes. In the US, we spend approximately $10.2 billion annually treating lymphoma.. NCI allocated 2.7% of its annual budget (or $137.0 million) in 2010 for lymphoma research.. The information in this section was also provided to the public courtesy of the NCI.

The B-cell lymphomas are types of lymphoma affecting B cells. Lymphomas are blood cancers in the lymph nodes. They develop more frequently in older adults and in immunocompromised individuals. B-cell lymphomas include both Hodgkins lymphomas and most non-Hodgkin lymphomas. They are typically divided into low and high grade, typically corresponding to indolent (slow-growing) lymphomas and aggressive lymphomas, respectively. As a generalisation, indolent lymphomas respond to treatment and are kept under control (in remission) with long-term survival of many years, but are not cured. Aggressive lymphomas usually require intensive treatments, with some having a good prospect for a permanent cure. Prognosis and treatment depends on the specific type of lymphoma as well as the stage and grade. Treatment includes radiation and chemotherapy. Early-stage indolent B-cell lymphomas can often be treated with radiation alone, with long-term non-recurrence. Early-stage aggressive disease is treated with ...

What is Burkitt Lymphoma?. Burkitt lymphoma is a form of non-Hodgkins lymphoma which is a type of cancer that starts in the b-cells. Burkitt lymphoma is one of the fastest growing tumors. Burkitt lymphoma attacks the immune system and is fatal if not treated in a timely manner. There are three types of Burkitts lymphoma endemic, sporadic, and immunodeficiency- associated.. What causes Burkitt lymphoma? Who is affected?. The exact cause of Burkitt lymphoma is unknown, but there are factors associated with the disease such as Epstein-Barr. Individuals who are immunosuppressed have a higher risk factor for Burkitt lymphoma. Burkitt lymphoma primarily affects African children, and malaria may make children more vulnerable.. What are the symptoms of Burkitt lymphoma?. There are many symptoms associated with Burkitt lymphoma, including:. ...
Treatment for primary CNS lymphoma includes chemotherapy and often radiation therapy. Steroid therapy (e.g. dexamethasone) is often given before chemotherapy, as this helps reduce the swelling around the tumour, and may even shrink the tumour, reducing the raised intracranial pressure. Chemotherapy is given into a vein, and often also into the fluid surrounding the brain (intrathecally). Methotrexate is the drug most commonly given this way, and is also given in high doses intravenously- either on its own or in combination with other chemotherapy drugs and/or steroids. Radiotherapy uses high-energy rays to destroy the cancerous cells and can be an effective treatment for primary CNS lymphoma in younger people. It is used in combination with chemotherapy and steroid treatment. Surgery is only used to provide diagnostic tissue, and is never curative alone. Anticonvulsants may be given if seizures occur as a result of a tumour. If treatment is insufficient or if the disease recurs, some people are ...
The proportion of black or Hispanic patients with HIV-associated NHL increased from 41% in 2004 to 55% in 2012 (P < .0001). Chemotherapy was received by 81% of patients with diffuse large B-cell lymphoma, 90% of those with Burkitt lymphoma, 61% of those with primary effusion lymphoma (PEL), and 35% of those with primary central nervous system lymphomas (PCNSL). Between 2004 and 2012, this proportion increased only for patients with PCNSL (P < .00001). Chemotherapy was less likely to be received by patients who were older, black, or without private insurance. It was delivered more frequently in hospitals designated as academic (OR for nonreceipt, 0.68; 95% CI, 0.51-0.92) or in hospitals that had ≥3 HIV-positive cases per year (OR, 0.71; 95% CI, 0.58-0.86). Survival improved in patients with diffuse large B-cell lymphoma (P = .007), Burkitt lymphoma (P = .0002), and PCNSL (P = .019), but not in those with PEL (P = .94). Receipt of chemotherapy in patients with PEL was not associated with better ...
Lymphoma is the most common haematopoietic malignancy in dogs, and is the most responsive to chemotherapy. Affected dogs are typically middle-aged. Neither gender nor neutering is a predisposing factor for developing lymphoma. In studies of canine lymphoma epidemiology; boxers, Scottish terriers, German shepherds and poodles were more often affected, and recent evidence suggests a high incidence in golden retrievers. The most common physical finding in dogs with lymphoma is peripheral lymphadenopathy, which is usually generalized but may be localized to a single lymph node or a region of the body. Involvement of other organs, such as spleen, liver, or bone marrow is an indication of advanced disease. Involvement of other (extranodal) sites is rare in dogs. Untreated lymphoma progresses rapidly (1-2 months) from presentation to terminal stages. With chemotherapy, however, considerable improvement in the duration and quality of the patients life can be expected.. Staging and Diagnosis. Lymphoma ...
This study is to find the effectiveness of pembrolizumab in patients with relapsed and refractory gray-zone lymphoma (GZL), primary central nervous system
Double-hit lymphomas and double-expressor lymphomas are some of the most difficult non-Hodgkin lymphomas to treat. Patients with these types of lymphomas, which are subtypes of diffuse large B-cell lymphoma, dont respond as well to chemotherapy treatment as other lymphoma patients do.. An estimated 22,000 patients nationwide are diagnosed with diffuse large B-cell lymphoma each year. About 5 to 10 percent have double-hit lymphoma (or cancer cells that contain chromosomal rearrangements of the MYC, BCL2 and/or BCL6 genes) and about 20 to 30 percent have double-expressor lymphoma (containing the MYC and BCL2 genes).. Which is why Alex F. Herrera, M.D., an assistant professor in City of Hopes Department of Hematology and Hematopoietic Cell Transplantation, and a team of doctors at City of Hope and the Dana-Farber Cancer Institute examined how well patients whose double-hit and/or double-expressor lymphoma had recurred, or was resistant to initial treatment, fared after they had received high-dose ...

Background Although chemo-immunotherapy has led to an improved overall survival for most B-cell lymphoma types, relapsed and refractory disease remains a challenge. The malaria drug artesunate has previously been identified as a growth suppressor in some cancer types and was tested as a new treatment option in B-cell lymphoma. Methods We included artesunate in a cancer sensitivity drug screen in B lymphoma cell lines. The preclinical properties of artesunate was tested as single agent in vitro in 18 B-cell lymphoma cell lines representing different histologies and in vivo in an aggressive B-cell lymphoma xenograft model, using NSG mice. Artesunate-treated B lymphoma cell lines were analyzed by functional assays, gene expression profiling, and protein expression to identify the mechanism of action. Results Drug screening identified artesunate as a highly potent anti-lymphoma drug.Artesunate induced potent growth suppression in most B lymphoma cells with an IC50 comparable to concentrations ...
This information is about non-Hodgkin lymphoma, a cancer that starts in the immune system. Non-Hodgkin lymphoma is also called NHL.. Non-Hodgkin lymphoma begins when a lymphocyte (usually a B cell) becomes abnormal. The abnormal cell divides to make copies of itself. The new cells divide again and again, making more and more abnormal cells. The abnormal cells dont die when they should. They dont protect the body from infections or other diseases. The buildup of extra cells often forms a mass of tissue called a growth or tumor.. Because lymphatic tissue is in many parts of the body, Hodgkin lymphoma can start almost anywhere. Usually, its first found in a lymph node.. When lymphoma is found, the pathologist reports the type. There are many types of lymphoma. The most common types are diffuse large B-cell lymphoma and follicular lymphoma.. Lymphomas may be grouped by how quickly they are likely to grow:. ...
Overview. Non-Hodgkins lymphoma is the seventh most common cancer in men and women in the United States. According to the American Cancer Society, 74000 new cases of non-Hodgkins lymphoma are diagnosed each year in the US. Non-Hodgkins lymphoma originates in the lymphatic system of the body. The lymphatic system fights diseases throughout the body. In non-Hodgkins lymphoma, tumors develop from white blood cells called lymphocytes. Lymph tissue is found in many places throughout the body, so lymphomas can start almost anywhere. Non-Hodgkins lymphoma is more common than the other type of general lymphoma, Hodgkin lymphoma. The major sites of lymph tissue are:. ...
Natural killer T (NKT) cells are a unique subset of CD1d-restricted T lymphocytes that express characteristics of both T cells and natural killer cells. NKT cells mediate tumor immune-surveillance; however, NKT cells are numerically reduced and functionally impaired in lymphoma patients. Many hematologic malignancies express CD1d molecules and co-stimulatory proteins needed to induce anti-tumor immunity by NKT cells, yet most tumors are poorly immunogenic. In this study, we sought to investigate NKT cell responses to B cell lymphoma. In the presence of exogenous antigen, both mouse and human NKT cell lines produce cytokines following stimulation by B cell lymphoma lines. NKT cell populations were examined ex vivo in mouse models of spontaneous B cell lymphoma, and it was found that during early stages, NKT cell responses were enhanced in lymphoma-bearing animals compared to disease-free animals. In contrast, in lymphoma-bearing animals with splenomegaly and lymphadenopathy, NKT cells were functionally
The therapeutic response to high-dose methotrexate (HD-MTX) therapy for primary central nervous system lymphoma (PCNSL) varies. Polyglutamylation is a reversible protein modification with a high occurrence rate in tumor cells. MTX incorporated into cells is polyglutamylated and strongly binds to dihydrofolate reductase without competitive inhibition by leucovorin (LV). Tumor cells with high polyglutamylation levels are selectively killed, whereas normal cells with lower polyglutamylation are rescued by LV. We hypothesized that the extent of polyglutamylation in tumor cells determines treatment resistance. Here, we investigated the therapeutic response of PCNSL to HD-MTX therapy with LV rescue based on polyglutamylation status. Among 113 consecutive PCNSL patients who underwent HD-MTX therapy in our department between 2001 and 2014, polyglutamylation was evaluated by immunostaining in 82 cases, with relationships between polyglutamylation and therapeutic response retrospectively examined.

Malignant lymphoma or lymphosarcoma are one of the common tumours in canine species such as dogs accounting for approximately 7-24% of all canine tumours and 83% of all canine blood cells malignancies. Canine lymphoma treatment are drugs used in the treatment and mitigation of tumours. Canine Lymphoma Treatment Market: Drivers and Restraints The rising incidences of canine lymphoma owing to drivers such as pet adoption, awareness, and development of breeds having high incidence of lymphomas such as Boxers, Bull Mastiffs, Basset Hounds, Saint Bernards, Scottish Terriers, Airedales and Bull dogs is the prime driver of the market. The growing median age of dog breeds is another driver of the market as lymphomas generally affect middle aged and older dogs with a median age of 6-9 years. The rise in risk factors such as infection by retrovirus and environmental factors such as use of herbicides, exposure to industrial fumes and chemicals such as paints and solvents, are driving as large demand. Weak ...

Hodgkin lymphoma is cancer that begins in the lymph system in white blood cells called lymphocytes. When these cells become abnormal, they grow without control and may form lumps of tissue called tumors.. The most common type of Hodgkin lymphoma is called classical Hodgkin lymphoma. The cancerous tumors (lymphomas) in classical Hodgkin lymphoma contain Reed-Sternberg cells. Non-Hodgkin lymphomas dont have these cells.. Symptoms of Hodgkin lymphoma include enlargement of the lymph nodes, fever, appetite loss, weight loss, and night sweats.. Hodgkin lymphoma affects men more often than women. The cause of Hodgkin lymphoma is not known.. Treatment for Hodgkin lymphoma depends on the stage of the lymphoma and may include radiation or chemotherapy.. ...
Brief Description: This is a case report of an elderly male who presented with sudden, painless loss of vision in one eye and a history of B-cell lymphoma, previously treated with chemotherapy. He was diagnosed with primary central nervous system lymphoma and ocular lymphoma. A review of ocular lymphoma diagnosis, pathophysiology, and management is undertaken ...
There are numerous signs and symptoms that can indicate that an individual has developed non-Hodgkins lymphoma. Because the condition can affect numerous areas of the body, the symptoms of the condition can also be found in several areas of the body. Not ever patient diagnosed with non-Hodgkins lymphoma will experience all of the symptoms of the condition and some of the indicating symptoms may appear without the individual developing non-Hodgkins lymphoma. If a person suspects that they may be developing or have developed non-Hodgkins lymphoma, it is very important to seek a confirming medical diagnosis right away. Non-Hodgkins lymphoma can be an aggressive condition and the sooner treatment can be started, the better chance the individual has of beating the condition.. Because non-Hodgkins lymphoma primarily affects the lymphatic system, the most common symptom of non-Hodgkins lymphoma is swollen lymph nodes in the body. The swollen lymph nodes can occur in the neck, groin, collarbone ...
Rituximab for treatment of advanced extranodal marginal zone B cell lymphoma of the mucosa-associated lymphoid tissue lymphoma. Background: Extranodal marginal zone B cell lymphoma of the mucosa-associated lymphoid tissue ( MALT) is a relatively common type of lymphoma. Owing to its B cell lineage, it appears to be a potential target for treatment with the CD20 antibody rituximab. We present an analysis of our experience with rituximab for treatment of patients with advanced MALT lymphoma. Patients and Methods: A retrospective analysis of patients with histologically verified MALT lymphoma undergoing treatment with rituximab was done. After reassessment of histological samples for the presence of MALT lymphoma, patients were evaluated as regards date of diagnosis, prior therapy for MALT lymphoma, sites of involvement upon treatment with rituximab, clinical response in terms of complete remission (CR), partial response ( PR), stable disease (SD) and progressive disease as well as symptomatic ...
Induction chemotherapy. High dose Methotrexate: The efficacy of Methotrexate in the treatment of Primary CNS lymphoma was first demonstrated by Ervin & Canellos in 1980 [17]. The primary CNS lymphoma cells inside brain are more sensitive to MTX and thus HD-MTX forms the backbone of PCNL therapy. HD-MTX is also shown a treatment related prognostic marker for survival in these patients [18]. There is no firm definition of HD-MTX and doses from 1g/m2 to 8 g/m2 has been reported in clinical trials [19]. Importantly Lippens and colleagues [20] demonstrated that intravenous administration of Methotrexate over 3 hours (3g/m2) leads to superior concentrations in cerebrospinal fluid (CSF) than infusion over 24 hours. Despite detectable meningeal disease in up to 15 % patients at diagnosis, intrathecal therapy has failed to achieve significantly better outcome [21]. Glantz et al demonstrated higher CSF levels after intravenous Methotrexate (8g/m2) than intrathecal injection with 12g/m2 Methotrexate [16]. ...

COMBINED MODALITY TREATMENT INCLUDING METHOTREXATE-BASED CHEMOTHERAPY FOR PRIMARY CEREBRAL NERVOUS SYSTEM LYMPHOMA: A SINGLE INSTITUTION EXPERIENCE
Primary central nervous system lymphoma is a rare neoplasm, exceptionally responsible for developing a frontal lobe syndrome. A 71-years-old patient with primary central nervous system lymphoma had undergone frontotemporal craniotomy for tumor removal. Month later, showing syncopies, disorientation and slurred speech, he was transported to Department of Internal Medicine. Neuroimaging revealed numerous tuberous changes in frontal and parietal lobes and frontotemporal area. During hospitalization, patient exhibited inadequate affect, jocular behaviour, was disoriented in the place and time, and unaware of his health state. He took repeated, uncritical attempts to jump out the window and started to exhibit persecutory delusions and hallucinations. Immediate brain radiotherapy was recommended by the oncology specialists. However, the patient did not consent to the recommended method of treatment due to his lack of recollection of the tumor or the craniotomy. The patient was forcibly transferred to ...

Cardiac involvement with lymphoma was the most significant clinical and pathological process in our patient. Our case fits into the broader clinical definition of primary cardiac lymphoma.1 The incidence of cardiac lymphoma in postmortem examination is low, with a reported range of 0.15% to 1%. Secondary cardiac infiltration from nodal lymphoma of the mediastinum appears to be more common in clinical practice.2 In the past, most cases were discovered in postmortem examination.3,4 Recently, case reports were dominated by antemortem diagnosis and chemotherapy.5 DLBCL accounts for 30% to 40% of all adult non-Hodgkin lymphomas. DLBCL is, however, the most common type of primary cardiac lymphoma. Eighty percent of the case reports and 60% of autopsy series revealed DLBCL.1. Most cases of cardiac lymphoma are solid, infiltrative nodule tumors in 1 or multiple chambers of the heart. The right heart is the most common site of cardiac lymphoma. Lymphomatous infiltration of the pericardium is also seen in ...

Hodgkin lymphoma is a rare cancer known in the past as Hodgkins Disease that accounts for less than 1% of all cancer cases in the United States. Hodgkin lymphoma develops from B lymphocytes, a type of white blood cell that normally produces proteins called antibodies that fight infection. Lymphocytes can be found in lymphoid tissue, which can be found throughout the body, in the lymph nodes, bone marrow, spleen, thymus, and digestive tract. Hodgkin lymphoma usually first starts in lymph nodes in the chest, neck, or underarms. However, Hodgkin lymphoma can also develop in other lymph nodes or lymphoid tissue in other parts of the body. It can also spread through the lymph system or bloodstream to other organs and parts of the body. The cancerous lymphocytes of Hodgkin lymphoma are called Reed-Sternberg cells, which look and behave differently than do normal lymphocytes and non-Hodgkin lymphoma cells. There are two primary categories of Hodgkin lymphoma: classical and ...
Daniel C. McFarland, DO; Joshua Brody, MD; Joseph Tripodi, MsS; Issa Leonard, BS; Vesna Najfeld, PhD. Mechanism of Action/Pathway Profiles. Remission in aggressive B-cell lymphomas is increasingly linked to complex karyotypes and gene rearrangements that often portend aggressive behavior and resistance to standard therapy. An understanding of lymphoma cytogenetics has lagged behind that of leukemia, in which pretreatment karyotype constitutes an independent prognostic determinant for attainment of complete remission. In 2008, the World Health Organization added the category B-cell lymphoma, unclassifiable, with features intermediate between diffuse large B-cell lymphoma and Burkitt lymphoma (BCLu-DLBCL/BL), which incorporates aggressive lymphomas with variable morphology. However, this category is nonspecific and does not elevate cytogenetic criteria to a diagnostic status based on chromosomal abnormalities as seen in acute leukemia. In part, this could be because cytogenetic analyses or ...

Although primary lymphomas of the central nervous system (PCNSL) and extracerebral diffuse large B-cell lymphoma (DLBCL) cannot be distinguished histologically, it is still a matter of debate whether PCNSL differ from systemic DLBCL with respect to their molecular features and pathogenesis. Analysis of the DNA methylation pattern might provide further data distinguishing these entities at a molecular level. Using an array-based technology we have assessed the DNA methylation status of 1,505 individual CpG loci in five PCNSL and compared the results to DNA methylation profiles of 49 DLBCL and ten hematopoietic controls. We identified 194 genes differentially methylated between PCNSL and normal controls. Interestingly, Polycomb target genes and genes with promoters showing a high CpG content were significantly enriched in the group of genes hypermethylated in PCNSL. However, PCNSL and systemic DLBCL did not differ in their methylation pattern. Based on the data presented here, PCNSL and DLBCL do not
Good morning everyone...Today Id like to talk about a study conducted in 2002 concerning feline lymphoma and secondhand cigarette smoke. The information gathered back then by scientists at Tufts School of Veterinary Medicine and the University of Massachusetts in a study called Environmental Tobacco Smoke and Risk of Malignant Lymphoma in Pet Cats showed a direct link to secondhand smoke and pet cats developing the cancer.. The findings of this study was published in the August, 2002 issue of American Journal of Epidemiology, show that cats who live with secondhand smoke are twice as susceptible. Increased feline lymphoma rates may even be as much as 65% greater than a cat living in a smoke-free environment. Figures for a cat living for 5 years in a tobacco smoking home increased to 3x the risk for developing lymphoma. When there are two smokers in a home the rate rises to 4x as likely.. Dogs living in a smoking home have a 60% risk of developing lung cancer.. The study was conducted at the ...
Marginal-zone lymphoma (MZL) is a malignancy that arises from B-lymphocytes in the marginal zone of lymphoid tissue. This slow-growing indolent B-cell lymphoma represents approximately 12% of all cases of non-Hodgkin lymphoma (NHL) in adults.1 MZL is divided into 3 subtypes, including mucosa-associated lymphoid tissue (MALT), nodal MZL, and splenic MZL.1. MALT lymphoma, the most common of these subtypes, occurs in the stomach, intestines, salivary glands, thyroid, eyes, and lungs.1 In contrast to the spleen and lymph nodes, the bodys organs normally lack lymphoid tissue. However, in MALT lymphoma, autoimmune processes or chronic infection cause B cells to accumulate.2,3 Helicobacter pylori is 1 of at least 6 microbial species associated with lymphoproliferation in gastric MALT lymphoma.3. Short-term antibiotic therapy is the initial treatment of gastric MALT lymphoma and is effective in approximately 70% to 90% of patients.1. Because the other types of MZL can appear in several areas of the ...
Hodgkins lymphoma is one of the most common lymphoid cancers, particularly among young adults. Although there have been dramatic improvements in the treatment of Hodgkins lymphoma, leading to high cure rates in some groups, current combination chemotherapy regimes are associated with significant secondary complications in long-term survivors. Furthermore, although a proportion of patients with Hodgkins lymphoma will be cured, there still remains a significant rate of relapse and also a smaller proportion of poor responders who will go on to die of their disease. Therefore, developments in the treatment of Hodgkins lymphoma must be directed at improving cure rates and reducing the burden of secondary complications. In recent years, the underlying pathogenesis of Hodgkins lymphoma has become better understood. In particular, it is emerging that a key pathogenic event in Hodgkins lymphoma is protection from Fas-induced cell death. Recent studies by the authors group, and others, have ...
Understanding Lymphoma. Canine lymphoma (also called lymphosarcoma or LSA) is one of the main cancers of dogs, accounting for approximately seven percent to 24% of all canine cancers. While it typically affects middle-aged and older dogs, it can occur in any aged dog, as well as any breed. It is a cancer of lymphocytes, which are small white blood cells that play a role in the bodys immune response in the fight against germs and diseases.. Though we do not know what causes lymphoma, it occurs when there is a change within the lymphocyte that causes it to become destructive and capable of reproducing without limits, and even invading other tissues. Some factors that may contribute to this malignant change include genetic predisposition, viral infection, and exposure to herbicides or electromagnetic radiation.. Classification. While it can be quite alarming to learn your dog has been diagnosed with LSA, it often responds quite well to treatment. Learning as much information as possible about your ...

Neurolymphomatosis (NL) is a rare clinical entity. The International Primary CNS Lymphoma Collaborative Group retrospectively analyzed 50 patients assembled from 12 centers in 5 countries over a 16-year period. NL was related to non-Hodgkin lymphoma in 90% and to acute leukemia in 10%. It occurred as the initial manifestation of malignancy in 26% of cases. The affected neural structures included peripheral nerves (60%), spinal nerve roots (48%), cranial nerves (46%), and plexus (40%) with multiple site involvement in 58%. Imaging studies often suggested the diagnosis with 77% positive magnetic resonance imaging, and 84% (16 of 19) positive computed tomography-positron emission tomography studies. Cerebrospinal fluid cytology was positive in 40%, and nerve biopsy confirmed the diagnosis in 23 of 26 (88%). Treatment in 47 patients included systemic chemotherapy (70%), intra-cerebrospinal fluid chemotherapy (49%), and radiotherapy (34%). Response to treatment was observed in 46%. The median overall ...
Your doctor needs to know the extent (stage) of non-Hodgkin lymphoma to plan the best treatment. Staging is a careful attempt to find out what parts of the body are affected by the disease.. Lymphoma usually starts in a lymph node. It can spread to nearly any other part of the body. For example, it can spread to the liver, lungs, bone, and bone marrow.. Staging may involve one or more of the following tests:. ...
Lymphoma: Primary lymphoma of the thyroid is uncommon, accounting for 2% of extranodal lymphomas and less than 5% of all malignant thyroid tumors. Most thyroid lymphomas are non-Hodgkin lymphomas. Patients present with a rapidly enlarging painless neck mass. Lymphomas may occur in the setting of Hashimoto thyroiditis. Mostly occurs in 7th decade of life, with a female to male ratio of six to one.. On ultrasound, thyroid lymphoma is characteristically very hypoechoic (see below image from Ultrasound Clinics Apr 2009) with a pseudocystic pattern (increased through transmission) similar to lymphoma seen in other organs, such as the liver or lymph nodes. ...

Previously, several groups have investigated the expression of MUC1 in malignant lymphomas. However, data on MUC1 expression in lymphomas are skewed in favour of the E29 (anti-EMA) monoclonal antibody,37 the one used most frequently in haematopathology. Furthermore, E29 does not distinguish between hyperglycosylated and hypoglycosylated MUC129; therefore, little is known about the MUC1 glycoforms present on lymphoma tumour cells. In our present study, we have used a panel of five monoclonal antibodies to study the expression and extent of glycosylation of MUC1 in ALCL and classic HD. As already described, these five antibodies all react to the immunodominant PDTRP(AP) sequence within the MUC1 protein core, but have different binding affinities, depending on the mode of glycosylation of MUC1.26,29,30,46. Our results show that MUC1, as detected by E29, DF3, and 139H2, is preferentially expressed in a subtype of systemic nodal ALCL, characterised by the presence of the ALK protein. E29 and DF3 ...
TY - JOUR. T1 - T-helper (TH)1/TH2 imbalance in patients with previously untreated B-cell diffuse large cell lymphoma. AU - Mori, T.. AU - Takada, R.. AU - Watanabe, R.. AU - Okamoto, S.. AU - Ikeda, Y.. PY - 2001. Y1 - 2001. N2 - T-helper (Th)1/Th2 imbalance has been observed in a variety of pathological conditions, including malignant diseases. We evaluated the Th1/Th2 balance in peripheral blood Th cells by means of intracellular cytokine analysis in 19 patients with previously untreated B-cell diffuse large cell lymphoma (DLCL) and in 18 patients with B-cell DLCL who had achieved complete remission (CR) after chemotherapy. The mean percentage of Th2 in CD4+ cells in patients with DLCL (5.00 ± 2.20) and that of Th1 in CD4+ cells in patients in CR (32.42 ± 11.30) were significantly increased in comparison with those in healthy volunteers, respectively (Th1; 23.02 ± 9.45, Th2; 3.25 ± 0.90; P , 0.01). The mean ratio of Th1/Th2 was significantly lower in patients with DLCL (4.74 ± 0.52) than ...
The effects of various concentrations of thymidine on DNA synthesis and deoxyribonucleoside triphosphate contents of a highly thymidine-sensitive cultured mouse lymphoma cell line (WEHI-7) and a relatively resistant mouse myeloma cell line (HPC-108) have been studied by 32P-labelling techniques. DNA synthesis in the myeloma cells was inhibited by thymidine at concentrations of 10(-3) M or greater, while DNA synthesis in the lymphoma cells was inhibited by concentrations 30-fold lower, consistent with the 25-fold difference between the two cell lines in sensitivity to growth inhibition by thymidine. Thymidine caused marked elevation of the dTTP and dGTP pools, slight elevation or no change in the dATP pool and a marked decrease in the dCTP pool in cells of both lines. The greater resistance of HPC-108 cells to thymidine inhibition was related to the finding that they normally contained a much higher concentration of dCTP than did the WEHI-7 cells. Pool size measurements on thymidine-treated (10(-4) M)

Recent studies have contributed to the enhancement of clinical and molecular knowledge on bone lymphomas, a group of rare malignancies with particular characteristics. Nevertheless, several questions remain unanswered and the level of evidence supporting some diagnostic and therapeutic decisions remains low. Currently, three different forms of bone lymphomas can be distinguished: the primary bone lymphoma, consisting of a single bone lesion with or without regional lymphadenopathies; the polyostotic lymphoma, consisting of multifocal disease exclusively involving the skeleton; and the disseminated lymphoma with secondary infiltration of the skeleton. The first two forms exhibit a good prognosis, requiring treatments similar to those commonly used for nodal lymphomas of the same category, but several issues regarding the role of surgery and local control of the disease, the sequence of treatment, radiation volumes and doses, management of pathological fractures and prevention of late sequelae deserve
