BACKGROUND: Previous studies on occupational exposures in parents and cancer risks in their children support a link between solvents and paints with childhood leukaemia. Few studies have focused specifically on benzene. OBJECTIVES: To examine whether parental occupational exposure to benzene is associated with an increased cancer risk in a census-based cohort of children. METHODS: From a census-based cohort study in Switzerland, we included children aged <16years at national censuses (1990, 2000)...

Mantle cell lymphoma (MCL) accounts for about 5% of all lymphomas. Its clinical and histological features are heterogeneous. After a frequently good initial response, the disease generally and repeatedly relapses and finally the outcome is poor. Particularly severe is the prognosis of the rare occurrence of CNSi (Central Nervous System involvement). Ibrutinib, an oral inhibitor of Bruton tyrosine kinase (BTK), has shown strong activity in relapsing patients with Chronic Lymphocytic Leukemia (CLL) and MCL. Few reports are available about treatment with ibrutinib of patients presenting CNSi by lymphoproliferative diseases (LPD)...

Lymphomas arising in the central nervous system (CNS) of immunocompromised hosts represent non-Hodgkin's lymphomas exclusively associated with Epstein-Barr virus (EBV). Here we report an autopsy case of EBV-associated CNS diffuse large B-cell lymphoma (DLBCL) in a host suffering from systemic lupus erythematosus who underwent immunosuppressive therapy. After autopsy, EBV-associated CNS DLBCL as well as pulmonary mixed aspergillosis and Pneumocystis jirovecii pneumonia were added to the clinical impressions of complicated pneumonia and cerebral hemorrhage in this immunocompromised patient...

We report on a 63-year old man suffering from rapid progressive dementia due to bilateral hippocampal primary CNS lymphoma. Early diagnosis especially in secondary dementia is essential because of potentially treatable aetiologies with regression of cognitive and behaviour abnormalities. Characteristic imaging findings especially in inflammatory and neoplastic lesions affecting the hippocampal structures are discussed.

Primary central nervous system (CNS) lymphomas account for 13-20% of the posttransplant lymphoproliferative disorders (PTLD) and rank among the most aggressive conditions. Reduction of immunosuppressive therapy should be mandatory to treat PTLD, but this is rarely used as the only therapy option. Chemotherapy regimens for PTLD involving the CNS most commonly include high-dose rituximab and high-dose methotrexate and/or cytarabine. The efficiency only of discontinuation of immunosuppressive therapy for PTLD does not exceed 5-10%, but there are no literature data on its efficiency for PTLD involving the CNS...

Neurolymphomatosis (NL) often represents unidentified non-Hodgkin lymphoma relapses. Considering its severity, early detection and treatment are crucial. We outline one hospital's (18)F-FDG-PET-CT imaging findings of NL, along with the patients' clinical characteristics. Clinical records and imaging findings of 19 NL patients, PET-CT diagnosed, were retrospectively reviewed. Patient data, FDG-PET-CT findings and the presence of coexisting diseases, especially CNS involvement, were documented. Available MRI and clinical data verified the findings...

OBJECTIVE: Primary central nervous system (CNS) lymphoma is an aggressive and fatal extranodal non-Hodgkin lymphoma (NHL) jailed in CNS at initial diagnosis. Its prognosis is poor and the disease has a fatal outcome when compared with systemic NHL. A few baseline risk stratification scoring systems have been suggested to estimate the prognosis mainly based on serum lactate dehydrogenase (LDH) level, age, Karnofsky performance score (KPS), involvement of deep brain structures (DBS) and cerebrospinal fluid protein concentration...

Background Central nervous system (CNS) relapse in non-Hodgkin lymphoma (NHL) is a rare but serious complication that carries a poor prognosis. The use of infusional etoposide, prednisone, vincristine, cyclophosphamide, doxorubicin, and rituximab (EPOCH-R) for frontline treatment of diffuse large B cell lymphoma (DLBCL) is increasing, though little is known about incidence of and risk factors for CNS relapse with this regimen Patients and methods We completed a chart review of patients with NHL who received EPOCH-R as front line therapy...

PURPOSE: Burkitt's lymphoma (BL) is a common HIV-associated lymphoma in South Africa. B-cell lymphoma unclassifiable with features intermediate between diffuse large B-cell lymphoma and Burkitt's lymphoma (BL/DLBCL) also occurs in HIV infection. Outcomes of HIV-infected patients with BL or BL/DLBCL in a resource-constrained setting are not defined. METHODS: We performed a retrospective study of HIV-positive patients with BL or BL/DLBCL treated from 2004 to 2012 with curative intent at a publically funded academic medical center in South Africa...

BACKGROUND ALK gene rearrangements as oncogenic drivers have been described in many cancers, including inflammatory myofibroblastic sarcoma (IMS). The first-generation ALK inhibitor was limited in its ability to cross the blood-brain-barrier to treat brain metastasis. Drug-resistance invariably develops over time in ALK-rearranged tumors, which leads to disease progression. The newer generations of ALK inhibitors are designed to have higher potency in ALK inhibition and improved CNS penetration. CASE REPORT We report a rare case of pulmonary IMS with ALK-1 gene rearrangement and multiple brain metastases as initial presentation...

Primary intraocular lymphoma (IOL) has a propensity for central nervous system (CNS) relapse within 2 years of initial diagnosis, affecting clinical outcome. To reduce CNS relapse, we performed the combination treatment protocols of intravitreal methotrexate injections, methotrexate-based systemic induction chemotherapy and consolidation high-dose cytarabine and reduced-dose whole brain radiation therapy (rdWBRT, 23·4 Gy) for B-cell primary IOL with or without newly diagnosed CNS involvement. All patients underwent longitudinal brain magnetic resonance imaging (MRI) and cognitive assessment for evaluation of treatment-induced leucoencephalopathy...

Central nervous system (CNS) relapse is an infrequent but severe complication for DLBCL patients, associated with poor prognosis. Intravenous prophylaxis with high-dose methotrexate has shown promising results but is rarely feasible in elderly and/or nephropathic patients. A 83 years old woman with CNS relapse occurred 6 months after chemoimmunotherapy. The patient was defined ineligible for radiotherapy (RT) and started oral Temozolomide 250mg daily for 5 consecutive days without any improvement after 1st cycle...

Central nervous system immune reconstitution inflammatory syndrome (CNS-IRIS), which occurs most often in HIV-infected patients, is an exacerbation of inflammatory reactions related to opportunistic infections as well as primary CNS malignancies both of which mostly occur in HIV-infected patients. However, differential diagnoses are challenging both clinically and radiologically. We describe a patient with CNS-IRIS due to toxoplasmosis whose (11)C-methionine uptake suggested lymphoma but whose arterial spin-labelling MRI led to the correct diagnosis...

Cystic brain metastases (CBM) have been recently reported in a minority of patients with anaplastic lymphoma kinase (ALK)-positive non-small cell lung cancer (NSCLC). All previously reported ALK-positive CBM developed during crizotinib treatment and were often asymptomatic and indolent, even without CNS-directed therapy. Thus, crizotinib was suggested as an etiologic agent for the development of CBM. Here, we report a case of de novo CBM in a patient with ALK-positive NSCLC prior to crizotinib treatment; the ALK-positive NSCLC had initially been misdiagnosed as neurocysticercosis because of the atypical radiological presentation of brain metastases...

The true incidence of light chain deposition disease (LCDD) restricted to the central nervous system (CNS) is unknown. To our knowledge only 7 cases of LCDD restricted to the brain have been previously reported. We herein describe an unusual example. A 44-year-old man presented with a history of ischemic retinopathy in 2004 and left lower extremity hypoesthesia in 2007 that progressed gradually to left-sided weakness and numbness in the 2 years prior to his hospitalization in 2015. A stereotactic brain biopsy was performed, displaying nonspecific hyaline deposits of amorphous "amyloid-like" material involving deep brain white matter and vessels...

WHAT IS KNOWN AND OBJECTIVE: Anaplastic lymphoma kinase (ALK)-rearranged non-small-cell lung cancer (NSCLC) is a distinct subtype with patients showing peculiar clinicopathological features and dramatic responses to the ALK tyrosine kinase inhibitor crizotinib. Patients with this cancer variant have a dismal prognosis and limited treatment options when it has progressed to intracranial metastasis because of inadequate drug penetration into the central nervous system (CNS). Factors associated with response to TKI therapy have been reported to include pharmacokinetic and biodynamic resistance phenomena...

PURPOSE/OBJECTIVE(S): Craniospinal irradiation (CSI) improves local control of leukemia/lymphoma with central nervous system (CNS) involvement; however, for adult patients anticipating stem cell transplant (SCT), cumulative treatment toxicity is a major concern. We evaluated toxicities and outcomes for patients receiving proton or photon CSI before SCT. METHODS AND MATERIALS: We identified 37 consecutive leukemia/lymphoma patients with CNS involvement who received CSI before SCT at our institution...
