PURPOSE: Although advanced MRI techniques are increasingly available, imaging differentiation between glioblastoma and primary central nervous system lymphoma (PCNSL) is sometimes confusing. We aimed to evaluate the performance of image classification by support vector machine, a method of traditional machine learning, using texture features computed from contrast-enhanced T1 -weighted images. METHODS: This retrospective study on preoperative brain tumor MRI included 76 consecutives, initially treated patients with glioblastoma (n = 55) or PCNSL (n = 21) from one institution, consisting of independent training group (n = 60: 44 glioblastomas and 16 PCNSLs) and test group (n = 16: 11 glioblastomas and 5 PCNSLs) sequentially separated by time periods...

Purpose In patients with crizotinib-treated, anaplastic lymphoma kinase gene ( ALK)-rearranged non-small-cell lung cancer (ALK-positive NSCLC), initial disease progression often occurs in the CNS. We evaluated brigatinib, a next-generation ALK inhibitor, in patients with ALK-positive NSCLC with brain metastases. Patients and Methods Patients with ALK-positive NSCLC received brigatinib (90 to 240 mg total daily) in a phase I/II trial (phI/II; ClinicalTrials.gov identifier: NCT01449461) and in the subsequent randomized phase II trial ALTA (ALK in Lung Cancer Trial of AP26113; ClinicalTrials...

Background: To describe the recent diagnostic and treatment options for the most predominant form of primary vitreoretinal lymphoma (PVRL), namely diffuse large B cell lymphoma. This is mainly based on the experience at the Mayo Clinic as well as a partial review of the literature. MYD88 L265P mutation is seen in about 80% of cases; therefore, a polymerase chain reaction for this mutation helps in making the diagnosis that has been notoriously difficult to make. Local therapy using intravitreal methotrexate and rituximab has been very helpful in the treatment of the local disease...

BACKGROUND: Primary central nervous system lymphomas (PCNSL) are rare in the paediatric population. CLINICAL CASE: A 12-year-old boy presented to our clinic with complaints of multiple episodes of generalised tonic-clonic seizures for 1 year and gradual loss of vision in both eyes for 3 months. Baseline magnetic resonance imaging (MRI) of the brain showed a large (7.2 × 7 cm) enhancing soft tissue lesion in the right frontal lobe causing mass effect and midline shift...

Background: Post-Transplant Lymphoproliferative Disorder (PTLD) is a well-recognized complication post solid organs transplant. PTLD represents a broad spectrum of abnormalities ranging from an infectious mononucleosis like illness to malignant lymphoma. Methods: A retrospective study was performed by collecting data of orthotopic liver transplant (OLT) patients in the National Liver Unit in Ireland from December 1993 to December 2014. Data was analyzed to identify PTLD patients and determine their demographic details, the indication for liver transplant, presenting symptoms, immunosuppression regimens, Epstein"Barr virus (EBV) status and PTLD outcome...

Primary central nervous lymphoma (PCNSL) is a rare extra-nodal subtype of non-Hodgkin lymphoma and most cases are of diffuse large B-cell lymphoma histology with an aggressive presentation. The treatment of PCNSL has evolved over the years from radiation alone to multi-agent chemotherapy with the goal of minimizing long-term toxicity. Recent studies have evaluated autologous stem cell transplant as consolidation in eligible patients with success. The prognosis of relapsed disease remains poor and hence the emphasis is on effective and less toxic frontline strategies...

BACKGROUND: The physical function of children with cancer is reduced during treatment, which can compromise the quality of life and increase the risk of chronic medical conditions. The study, "REhabilitation, including Social and Physical activity and Education in Children and Teenagers with cancer" (Clinicaltrials.gov: NCT01772862) examines the efficacy of multimodal rehabilitation strategies introduced at cancer diagnosis. This article addresses the feasibility of and obstacles to testing physical function in children with cancer...

Background: Primary extranodal marginal zone lymphoma (MZL) of the dura is a rare neoplastic entity in the central nervous system (CNS). Methods: We used literature searches to identify previously reported cases of primary dural MZL. We also reviewed clinical, pathologic, and radiographic data of an adult patient with concurrent dural MZL and chronic lymphocytic leukemia (CLL)/small lymphocytic lymphoma (SLL). Results: We identified 104 cases of dural MZL in the literature...

Gliomas are the most common malignant brain tumors and account for around 60% of all primary central nervous system cancers. Glioblastoma multiforme (GBM) is a grade IV glioma associated with a poor outcome despite recent advances in chemotherapy. The etiology of gliomas is unknown, but neurotropic viruses including the Epstein-Barr virus (EBV) that is transmitted via salivary and genital fluids have been implicated recently. EBV is a member of the gamma herpes simplex family of DNA viruses that is known to cause infectious mononucleosis (glandular fever) and is strongly linked with the oncogenesis of several cancers, including B-cell lymphomas, nasopharyngeal, and gastric carcinomas...

Objective To evaluate the role of minimum apparent diffusion coefficient(MinADC) values in peritumoral edema based on magnetic resonance diffusion weighted imaging in the differential diagnosis between primary central nervous system lymphoma(PCNSL) and glioblastoma(GBM).Methods ADC values in peritumoral edema were measured in 16 patients with PCNSL(diffuse large B cell lymphoma) and 31 patients with GBM(WHO grade 4) confirmed by pathology.Regions of interests were manually drawn on ADC maps on peritumoral edema regions to obtain the MinADC value...

Treatment strategies and outcomes were assessed in 25 patients with primary breast diffuse large B-cell lymphoma (PB-DLBCL) treated between 1995 and 2016. We specifically investigated the timing of recurrence, and the roles of radiotherapy (RT) and central nervous system prophylaxis (CNS PPX). Fifty-two percent of patients received RT, and 28% received CNS PPX. Fourteen patients (56%) experienced recurrence, with 76% of relapses occurring ≥24 months after diagnosis, in contrast to reports supporting the use of 24-month event-free survival as a surrogate endpoint in the general DLBCL population...

Primary central nervous system lymphoma (PCNSL) is a rare topographic variant of diffuse large B-cell lymphoma (DLBCL). While prognostic scales are useful in clinical trials, no dynamic prognostic marker is available in this disease. We report here the prognostic value of early metabolic response by 18F-FDG PET scanner (PET) in 25 newly diagnosed immunocompetent PCNSL patients. Induction treatment consisted of four cycles of Rituximab, Methotrexate and Temozolamide (RMT). Based on patient's general condition, consolidation by high-dose Etoposide and Aracytine was given to responding patients...

BACKGROUND: Primary central nervous system lymphoma (PCNSL) is a relatively common tumor of the central nervous system. Although PCNSLs generally arise from the parenchyma, lymphomas arising primarily from the dura are termed dural lymphomas (DL). Mucosa-associated lymphoid tissue is the most unique histological feature of DL. Due to its rarity, clinical characteristics and treatments for DL have not been fully elucidated to date. CASE DESCRIPTION: A 31-year-old man with no past medical history presented with numbness in his left upper limb...

Context: Lymphomatoid granulomatosis (LYG) is a rare B-lymphoproliferative disorder characterised by an angiocentric and angiodestructive pattern along with Epstein - Barr virus (EBV) association. It is one of the diagnostic challenges in lymphoma pathology. Deregulation of EBV immune surveillance is one of the narrated hypotheses in the literature. Extrapulmonary manifestations are rare with LYG. Morphological grading is done based on the number of EBV-positive B cells, which is useful to strategize treatment protocol...

The central nervous system (CNS) is a common site of disease progression in patients with non-small-cell lung cancer (NSCLC) with anaplastic lymphoma kinase (ALK)-rearrangement treated with crizotinib. Cystic brain metastases (CBM) have been recently identified as one possible variant of this disease. An illustrative case report is presented along with a literature review performed in order to track relevant papers about CBM in ALK-rearranged NSCLC, including possible pathophysiology, differential diagnosis and treatment options for this condition...
