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...

Secondary central nervous system (CNS) relapse is a serious and fatal complication of diffuse large B cell lymphoma (DLBCL). Data on secondary CNS (SCNS) relapse were mostly obtained from western countries with limited data from developing countries. We analyzed the data of 2034 newly diagnosed DLBCL patients enrolled into the multi-center registry under Thai Lymphoma Study Group from setting. The incidence, September 2006 to December 2013 to represent outcome from a resource limited pattern, management, and outcome of SCNS relapse were described...

Classically, the HIV/AIDS-related lymphomas are of the B cell type and involve the central nervous system and the abdominal cavity. Primary maxillary sinus lymphoma is rare. Plasmablastic lymphoma (PBL) is an aggressive form of non-Hodgkinvs lymphoma, and is extremely rare. Here we present a case of plasmablastic lymphoma with primary site being maxillary sinus, a rare location.

Diffuse large B-cell lymphoma (DLBCL) accounts for 30-40% of all lymphoma subtypes. More than half of DLBCLs are estimated to arise from extranodal sites, and are called extranodal DLBCLs. Generally, the outcomes of extranodal DLBCL are not different from those of nodal DLBCL. To our knowledge, this report is the first to discuss the concept and the cell of origin of extranodal DLBCL, with the significance of the presence/absence of each involvement site in determining the outcome. Second, the evidence of clinical manifestation and outcomes of several extranodal DLBCLs requiring treatments other than R-CHOP, which is the current standard therapy for this malignancy, are discussed...

High-dose therapy and autologous stem cell transplantation (HDT-ASCT) with thiotepa, busulfan, cyclophosphamide (TBC) conditioning has emerged as an effective post-induction treatment strategy for patients with primary (PCNSL) or secondary central nervous system lymphoma (SCNSL), but it is associated with considerable toxicity and transplant-related mortality (TRM) in the modern era. Forty-three adult patients with chemosensitive PCNSL or SCNSL received TBC conditioned ASCT between 2006 and 2015. Twenty-eight of these patients received pharmacokinetically (PK)-targeted busulfan dosing...

There are 2 types of central nervous system lymphoma: primary and secondary. Both have variable imaging features making them diagnostic challenges. Furthermore, a patient's immune status significantly alters the imaging findings. Familiarity with typical appearances, variations, and common mimics aids radiologists in appropriately considering lymphoma in the differential diagnosis. Moreover, special types of lymphoma, such as lymphomatosis cerebri, intravascular lymphoma, and lymphomatoid granulomatosis, also are found...

Primary central nervous system lymphomas are aggressive, high-cell-density tumors. There is recent increase in their incidence in immunocompetent patients. Knowledge of imaging findings on computed tomography and conventional MR imaging is important to suggest the diagnosis. Moreover, information obtained from advanced MR imaging techniques, such as diffusion-weighted imaging, diffusion tensor imaging, MR spectroscopy, perfusion-weighted imaging, and dynamic contrast-enhanced studies, increases diagnostic confidence and helps distinguish them from other aggressive intracranial tumors...

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...

We recently reported a truncating deletion in the NFKBIE gene, which encodes IκBϵ, a negative feedback regulator of NF-κB, in clinically aggressive chronic lymphocytic leukemia (CLL). Preliminary data indicate enrichment of NFKBIE aberrations in other lymphoid malignancies, hence we screened a large patient cohort (n=1460) diagnosed with different lymphoid neoplasms. While NFKBIE deletions were infrequent in follicular lymphoma, splenic marginal-zone lymphoma, and T-cell acute lymphoblastic leukemia (<2%), slightly higher frequencies were seen in diffuse large B-cell lymphoma, mantle cell lymphoma, and primary CNS lymphoma (3-4%)...

Chronic lymphocytic inflammation with pontine perivascular enhancement responsive to steroids (CLIPPERS) has been recently identified as an inflammatory central nervous system (CNS) disorder. Punctate and curvilinear gadolinium enhancement (peppering) the pons is a characteristic magnetic resonance imaging (MRI) feature of CLIPPERS. Pathogenesis of this disorder remains unknown. A specific serum or cerebrospinal fluid biomarker for this disorder is currently unknown. Whether CLIPPERS is an actual new disease or just represents overlapping symptoms from multiple diseases is still debated...

Dural lymphoma (DL) is a rare type of primary CNS lymphoma arising from the dura mater. The optimal treatment is uncertain. A retrospective review was performed on 26 DL patients. Seventeen patients underwent resection and nine had a biopsy. Twenty three patients could be assessed for a response to treatment after surgery. Thirteen received focal radiotherapy (RT), six whole brain RT (WBRT), three chemotherapy alone and one chemotherapy followed by WBRT. Twenty two achieved complete response (CR) and one a partial response (PR)...

Primary Testicular Lymphoma (PTL) is a rare intermediate to high grade tumour, diffuse large cell being the most common type. Unlike nodal Diffuse Large B-Cell Lymphoma (DLBCL), testicular DLBCL has a less aggressive course and better prognosis. Metastasis is uncommon in testicular DLBCL. Commonly involved sites are contralateral testes, Waldeyer's ring, skin, lung, Central Nervous System (CNS) and prostate, however the kidneys, liver, bone marrow, pleura and bones are more rarely involved. We report a case of testicular DLBCL which has metastasized to skin and bone marrow with an aggressive clinical course in a year, in-spite of combined modality of therapy given to the patient...

The head and neck are common sites for extranodal non-Hodgkin lymphomas. Radiotherapy plays an important role in the treatment of low-grade lymphomas, with curative or palliative intent. In the case of high-grade lymphomas, its combination with chemotherapy is debated. Its role is however undeniable in two specific entities: NK/T-cell lymphoma NK/T nasal type, and primary central nervous system lymphomas, which are the subject of this review.

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...
