Primary central nervous system lymphoma (PCNSL) is an extranodal non-Hodgkin lymphoma (NHL) confined to the brain, leptomeninges, eyes, or spinal cord. The majority of PCNSL cases occur in the immunocompetent host, the focus of this review. The prognosis of PCNSL is inferior to that of other NHL subtypes including other organ-specific subtypes of extranodal NHL. The 5- and 10-year survival proportions for PCNSL are 29.3% and 21.6%, respectively. The diagnosis and management of PCNSL differs from that of other primary brain cancers and NHL in other parts of the body...

BACKGROUND: Primary central nervous system lymphoma (PCNSL) is a rare, aggressive brain neoplasm that accounts for roughly 2-6% of primary brain tumors. In contrast, glioblastoma (GBM) is the most frequent and severe glioma subtype, accounting for approximately 50% of diffuse gliomas. The aim of the present study was to evaluate morphological MRI characteristics in histologically-proven PCNSL and GBM at the time of their initial presentation. METHODS: We retrospectively evaluated standard diagnostic MRI examinations in 54 immunocompetent patients (26 female, 28 male; age 62...

Lymphomatosis cerebri (LC) is a rare variant of a primary central nervous system non-Hodgkin's lymphoma (PCNSL) characterised by diffuse infiltration of tumour cells throughout the brain parenchyma. We present a 68-year-old immunocompetent woman with headaches, dizziness, blurred vision, localised right leg weakness and rapidly progressive dementia. A brain MRI demonstrated diffuse T2 hyperintense white matter lesions that did not enhance with contrast. The clinical differential diagnosis of these lesions included metastatic disease, infectious or inflammatory process such as sarcoidosis, lymphoma, demyelinating disease and less likely vascular aetiology, such as vasculitis or ischaemic stroke...

Primary central nervous system lymphoma (PCNSL) is an extranodal Non-Hodgkin's lymphoma that is confined to the brain, eyes, and/or leptomeninges without evidence of a systemic primary tumor. Although the tumor can affect all age groups, it is rare in childhood; thus, its incidence and prognosis in children have not been well defined and the best treatment strategy remains unclear. A nine-year old presented at our department with complaints of diplopia, dizziness, dysarthria, and right side hemiparesis. Magnetic resonance image suggested a diffuse brain stem glioma with infiltration into the right cerebellar peduncle...

To investigate immuno-chemotherapy for elderly immuno-competent patients (⩾65 years) with newly diagnosed primary central nervous system lymphoma (PCNSL), we conducted a multicentre single arm trial. One cycle consisted of rituximab (375 mg/m(2), day 1, 15, 29), high-dose methotrexate (3 g/m(2) days 2, 16, 30), procarbazine (60 mg/m(2) day 2-11), and lomustine (110 mg/m(2), day 2)-R-MPL protocol. Due to infectious complications we omitted lomustine during the study and consecutive patients were treated with the R-MP protocol...

Primary central nervous system lymphoma (PCNSL) is a rare brain tumour with a dismal prognosis. Several phase II studies with high-dose methotrexate-based regimens have shown promising early results, but in all hospital-based data published so far, the disease outcome has been poor. Patients with relapsed or refractory disease have a dismal prognosis. We performed retrospective analysis to evaluate results and tolerabilities of BBBD therapy in combination with high-dose therapy supported by autologous stem cell transplantation...

High-dose therapy and autologous stem cell transplantation (ASCT) with thiotepa, busulfan, and cyclophosphamide (TBC) conditioning has emerged as an effective postinduction treatment strategy for patients with primary central nervous system lymphoma (PCNSL) or secondary central nervous system lymphoma (SCNSL), but it is associated with considerable toxicity and transplantation-related mortality (TRM) in the modern era. Forty-three adult patients with chemosensitive PCNSL or SCNSL underwent TBC-conditioned ASCT between 2006 and 2015...

Primary central nervous system lymphoma (PCNSL) is a distinct subtype of extranodal lymphoma with aggressive clinical course and poor outcome. As increased IL-10/IL-6 ratio is recognized in the cerebrospinal fluid (CSF) of PCNSL patients, we hypothesized that PCNSL might originate from a population of B cells with high IL-10-producing capacity, an equivalent of "regulatory B cells" in mice. We intended in this study to clarify whether Tim-1, a molecule known as a marker for regulatory B cells in mice, is expressed in PCNSL...

INTRODUCTION: Primary central nervous system lymphoma (PCNSL) of T-cell origin is an exceptionally rare, highly malignant intracranial neoplasm. Although such a tumor typically presents with a focal mass lesion. CASE REPORT: Past medical history of a 26-year-old male patient with a PCNS lymphoma of T-cell origin was not suggestive of intracranial pathology or any disorder of other organs and organic systems. To achieve a gross total tumor resection, surgery was performed via osteoplastic craniotomy using the left frontal transcortical transventricular approach...

BACKGROUND: Central nervous system lymphomas (CNSL) are traditionally regarded as non-surgically treated tumors with a poor prognosis. Usually, only stereotactic biopsy is performed to establish the diagnosis, and most patients show disease progression within half a year. A recent study questioned this view, since patients who had surgical resection of PCNSL manifestations prior to adjuvant therapy reportedly had a better outcome than patients who had biopsy only. METHODS: We performed a retrospective analysis of our patient database to identify patients with CNSL who had undergone "accidental" tumor removal in our department between 2002 and 2013...

Chemoradiotherapy for primary central nervous system lymphoma (PCNSL) is associated with a considerable risk of long-term neurotoxicity. The present study aimed to assess the health-related quality of life (HRQOL) of outpatients with PCNSL who have received radiotherapy and high-dose methotrexate (HDMTX) chemotherapy, and to determine the factors that cause a decline in HRQOL and interfere with home living. A total of 37 patients were surveyed 0.9-14.2 years after their initial diagnosis and treatment. Each patient completed a multi-part HRQOL questionnaire that was used to examine the associations of HRQOL scores with leukoencephalopathy, Karnofsky performance status (KPS) scores, age, history of recurrence and HDMTX-based chemoradiotherapy...

Primary intracranial lymphomas (Weller et al. in Neuro Oncol 14(12):1481-1484, 2012) are an emerging disease and an isolated localization in the pituitary gland i.e. primary pituitary lymphoma (PPL) represents a rare condition. We present an update of the most recent evidence for PPL through a systematic review of the literature. A systematic literature review was conducted using PubMed database up to October 2015. The population was defined as immunocompetent patients with a pathologically confirmed diagnosis of PPL...

BACKGROUND: The optimal therapeutic approach for patients with AIDS-related primary central nervous system lymphoma (AR-PCNSL) remains undefined. While its incidence declined substantially with combination antiretroviral therapy (cART), AR-PCNSL remains a highly aggressive neoplasm for which whole brain radiotherapy (WBRT) is considered a standard first-line intervention. METHODS: To identify therapy-related factors associated with favorable survival, we first retrospectively analyzed outcomes of AR-PCNSL patients treated at San Francisco General Hospital, a public hospital with a long history of dedicated care for patients with HIV and AIDS-related malignancies...

BACKGROUND: Primary central nervous system lymphoma (PCNSL) is a rare cancer accounting for less than 3% of primary brain and central nervous system (CNS) tumors. Tissues involved include the brain parenchyma, leptomeninges, eyes, and spinal cord. High-dose methotrexate (MTX) is the gold standard for newly diagnosed PCNSL. However, Gamma Knife radiosurgery (GKRS) may be efficacious as a co-adjuvant treatment. The purpose of this prospective observational cohort study is to determine the effectiveness of MTX in combination with GKRS in the treatment of PCNSL...

BACKGROUND: Brain stereotactic biopsy (SB) followed by conventional histopathology and immunohistochemistry (IHC) is the gold standard approach for primary central nervous system lymphoma (PCNSL) diagnosis. Flow cytometry (FCM) characterization of fine-needle aspiration cytology and core needle biopsies are increasingly utilized to diagnose lymphomas however, no biological data have been published on FCM characterization of fresh single cell suspension from PCNSL SB. The aim of this study was to establish the feasibility and utility of FCM for the diagnosis and characterization of brain lymphomas from a tissue samples obtained by a single SB disaggregation...

BACKGROUND: Mammalian target of rapamycin (mTOR) complex 1 (mTORC1) acts as a downstream effector of phosphatidyl-inositol-3 kinase, which is frequently hyperactivated in glioblastoma multiforme and links to cell signaling in cellular proliferation, differentiation, metabolism, and survival. Although many studies have suggested the importance of mTORC1 in tumorigenesis, its role remains unclear in brain tumors other than glioblastoma. METHODS: In the present study, we evaluated the activation of mTORC1 in 24 cases of primary central nervous system lymphoma (PCNSL)...

In diffuse large B-cell lymphoma (DLBCL), the germinal center B-cell (GCB) subtype is associated with a better prognosis compared with the nongerminal center B-cell-like (non-GCB) subtype. However, validity of this immunohistochemical subgrouping in primary DLBCL of the central nervous system is unclear. A total 45 cases of primary central nervous system lymphoma (PCNS)/DLBCL were selected, and immunohistochemistries for CD10, Bcl-6, MUM1, and Ki-67 were performed. Each of the cases was subclassified as either GCB or non-GCB based on its immunoprofile...
