PURPOSE: In the randomized G-PCNSL-SG-1 trial, the addition of whole brain radiotherapy (45 Gy) to high-dose methotrexate (HD-MTX)-based chemotherapy (early WBRT arm) did not prolong overall survival (OS) as compared to HD-MTX-based chemotherapy alone (no early WBRT arm) in primary CNS lymphoma (PCNSL) patients. To determine whether WBRT might lead to quality of life (QoL)-relevant late neurotoxicity, this trial prospectively monitored QoL. METHODS: QoL measurements were performed using the EORTC-QLQ-C30 and BN20 questionnaires and combined with repeated Mini Mental State Examinations (MMSE)...

Primary CNS lymphoma (PCNSL) is chemosensitive to high-dose methotrexate-based chemotherapy. However, responses in the elderly are short-lasting and outcome is poor. Given that radiotherapy and intensive chemotherapy expose elderly to severe toxicities, alternative consolidation approaches need to be evaluated. In this multicenter study, we retrospectively analyzed consecutive patients with newly-diagnosed PCNSL, aged >60, treated with a (R)-MPV-AAA regimen. The regimen consisted of three 28-day cycles of methotrexate (3...

Systemic lupus erythematosus (SLE) is a multisystem autoimmune disorder punctuated by varied multiorgan complications all along the course of its natural history. Lymphoma represents a relatively well-recognized malignant phenomenon associated with lupus. The cause and effect relationships of lymphoma in SLE have been subject to extensive scrutiny with several studies reporting on clinic-pathologic characteristics and risk factors predicting lymphoma development in SLE. However, the pathogenic role of immunosuppressives in SLE-related lymphoma still remains unclear, and indices to help guide diagnosis, prognostication, therapy, and posttreatment monitoring are yet to be established...

Primary CNS lymphomas (PCNSL) represent a subgroup of malignancies with specific characteristics, aggressive course, and unsatisfactory outcome in contrast with other lymphomas comparable for tumour burden and/or histological type. Despite a high chemo- and radiosensitivity, remissions are frequently shortlasting, mainly because the blood brain-barrier limits the access of many drugs to the CNS. Moreover, survivor patients are at high risk of developing severe treatment-related toxicity, mainly disabling neurotoxicity, raising the question of how to balance therapy intensification with side-effects control...

Background: Intravascular large B-cell lymphoma (IVLBCL) is a rare type of extranodal lymphoma with growth mainly in the lumina of vessels. We studied a small series of IVLBCL and focused on its central nervous system (CNS) involvement. Materials and Methods: Searching the medical records of Northwestern Memorial Hospital, we identified five cases of IVLBCL from January 2007 to January 2015. Clinical information, hematoxylin and eosin stained histologic slides and immunohistochemistry studies were reviewed for all cases...

Extranodal natural killer (NK)/T-cell lymphomas are rare, highly aggressive tumors of the central nervous system (CNS) that commonly affect the nasal cavity or paranasal sinuses. NK/T-cell lymphomas are associated with a poor prognosis, as they exhibit a wide range of unique clinical presentations and neuroimaging findings that are currently difficult to detect. Pathological examination is considered to be more reliable for defining the pathological entity of NK/T-cell lymphoma. Early testing for fluorodeoxyglucose (FDG)-positron emission tomography combined with computed tomography may improve the evaluation of lymphomas, which have been known to display avid (18)FDG uptake...

BACKGROUND: Cancer is a major cause of death in children worldwide, and the recorded incidence tends to increase with time. Internationally comparable data on childhood cancer incidence in the past two decades are scarce. This study aimed to provide internationally comparable local data on the incidence of childhood cancer to promote research of causes and implementation of childhood cancer control. METHODS: This population-based registry study, devised by the International Agency for Research on Cancer in collaboration with the International Association of Cancer Registries, collected data on all malignancies and non-malignant neoplasms of the CNS diagnosed before age 20 years in populations covered by high-quality cancer registries with complete data for 2001-10...

Inflammatory myofibroblastic tumors (IMT) of the central nervous system (CNS) are rare entities that have a predilection for local recurrences. Approximately half of the inflammatory myofibroblastic tumors contain translocations that result in the over-expression of the anaplastic lymphoma kinase (ALK) gene. We hereby present the case of a patient diagnosed with a left parieto-occipital IMT that recurred after multiple surgeries and radiotherapy. Immuno-histochemical examination of the tumor demonstrated ALK overexpression and the presence of an ALK rearrangement observed in lung cancers...

Central nervous system (CNS) toxicity has been reported in approximately 10%-30% of patients receiving intravenous infusions of ifosfamide. Encephalopathy is a rare but serious CNS adverse reaction in these patients, and although usually transient and reversible, may cause persistent neurological dysfunction or death. Clinical features range from fatigue and confusion to coma and death. Ifosfamide forms backbone of various treatment regimens including curative treatment and palliative chemotherapy regimen. Precipitation of ifosfamide-induced encephalopathy (IIE) by aprepitant has been reported in the literature rarely...

Hitherto poor outcomes, paucity of data and heterogeneity in International approach to Pediatric NHL (Non-Hodgkin Lymphoma) prompted the need for guidelines for Indian population with vast variability in access, affordability and infrastructure across the country. These guidelines are based on consensus among the experts and best available evidence applicable to Indian setting. Evaluation of NHL should consist of easily doable and rapid tissue diagnosis (biopsy or flow cytometry of peripheral blood/malignant effusions), St Jude/IPNHLSS (International Pediatric Non-Hodgkin Lymphoma Staging System) and risk grouping with CSF (Cerebro-spinal fluid), bone marrow, whole body imaging [CECT (Contrast enhanced computerized tomography) ± MRI (Magnetic resonance imaging)] and blood investigations for LDH (Lactate dehydrogenase), TLS (Tumor lysis syndrome) and organ functions...

BACKGROUND: High-dose chemotherapy and autologous stem cell transplantation (HDC-ASCT) is a therapeutic option for patients with primary central nervous system lymphoma (PCNSL). To the authors' knowledge, data are limited regarding its use among patients in first complete remission (CR1) with the CNS-directed conditioning regimen of thiotepa, busulfan, and cyclophosphamide (TBC). METHODS: A retrospective analysis of patients with PCNSL in CR1 who underwent transplantation using a TBC-based conditioning regimen at 2 academic institutions was performed...

Primary CNS lymphomas (PCNSL) are relatively rare brain tumors. Their accurate diagnosis is mainly by surgical biopsy. In addition to surgical biopsy/decompression, treatment options include high dose methotrexate/chemotherapy and radiation therapy and stem cell therapy. Due to the rarity of this disease, guidelines for PCNSL diagnosis and treatment usually form from a large series of experiences. As a tertiary referral center, we retrospectively reviewed 79 patients during a 13-year period. All patients with PCNSL underwent surgical procedures/bone marrow biopsy procedures, and diagnoses were confirmed by hematologists/neuropathologists...

BACKGROUND AND IMPORTANCE: Collision tumors are the simultaneous occurrence of more than one type of neoplasm within an anatomic space. In the pituitary sella, collision tumors are exceedingly rare, and not much is known about their etiology and prognosis. CLINICAL PRESENTATION: A 74-year-old man presented with a concomitant primary pituitary lymphoma (diffuse large B-cell non-Hodgkin's lymphoma; DLBCL) and follicle-stimulating hormone (FSH)-adenoma diagnosed histologically after clinical features of apoplexy prompted urgent surgical decompression and resection...

As an uncommon disease, primary bone marrow diffuse large B-cell lymphoma (PBM DLBCL) is rarely reported in recent years. In this paper, we discuss a case of a 58-year-old man who presented with fever and fatigue, and was diagnosed with PBM DLBCL. Although the initial diagnosis reflected a positive expression of CD20 by lymphoma cells, the course of disease appeared as a rapid remission but a quick recurrence, after eight cycles of rituximab-based immunochemotherapy (R-CHOP). With the positive expression of CD20 in recurrent lesions, he received another four cycles of rituximab-based immunochemotherapy (R-GDP)...

Primary central nervous system lymphoma (PCNSL) and primary testicular lymphoma (PTL) are rare extranodal large B-cell lymphomas with similar genetic signatures. There are no standard of care treatment options for patients with relapsed and refractory PCNSL and PTL, and the overall prognosis is poor. PCNSLs and PTLs exhibit frequent 9p24.1 copy number alterations and infrequent translocations of 9p24.1 and associated increased expression of the programmed cell death protein 1 (PD-1) ligands PD-L1 and PD-L2...

AIMS: The central nervous system (CNS) is a rare primary site of non-Hodgkin lymphoma. Although direct invasion of nasal NK/T-cell tumours into CNS is occasionally reported, primary CNS NK/T-cell lymphoma is extremely rare, and the clinicopathological features of primary CNS NK/T-cell lymphoma remain largely unknown. METHODS AND RESULTS: We identified four cases from our consultation files and analysed the clinicopathological features. Three were immunocompetent (IC) and one was immunosuppressive patient...

BACKGROUND: Conventional magnetic resonance imaging (MRI) under consideration of clinical information enables the correct diagnosis and therapy for the majority of cerebral space-occupying lesions. Some important differential diagnoses, e. g. low vs. high-grade tumors, require additional MRI methods. OBJECTIVE: This article critically discusses the importance of magnetic resonance spectroscopy ((1)H-MRS) in brain tumors. MATERIAL AND METHODS: The concentration of normal and pathological brain metabolites can be non-invasively measured by (1)H-MRS...
