Systemic reports on the descriptive epidemiology of non-Hodgkin lymphoma (NHL) from Southeast Asia are scarce. A nationwide multi-institutional registry was conducted to compare the histopathology, clinical features, and survival of Thai adult patients with NHL using large registries, especially those from Far East Asia (FEA). Using a web-based registry system, 13 major medical centers from the 4 geographic regions of Thailand prospectively collected, from 2007 to 2014, the diagnostic pathology, according to the World Health Organization classification, 2008, clinical features and survival of 4056 patients who were newly diagnosed with NHL...

Definitive diagnosis of cutaneous lymphoproliferative disorders is one of the most challenging issues in dermatopathology owing to the broad spectrum of clinical and histopathological presentations. We report a case of a 73-year-old woman who presented with a single, asymptomatic plaque limited to her left collarbone. This was followed by the appearance of several plaques and patches in addition to a tumor. Her initial biopsy suggested a CD4/CD8 double negative mycosis fungoides (MF). However, the rapidly progressive course of her disease is worrisome for peripheral T-cell lymphomas-not otherwise specified (PTCL-NOS)...

In the present study, we investigate the outcome of 109 Danish and 123 Swedish patients with nodal PTCL in first complete remission (CR), and examine the impact of imaging-based follow-up (FU) strategies. The patients were selected by the following criteria: (a) newly diagnosed nodal PTCL from 2007 to 2012, (b) age ≥18 years, and (c) CR after CHOP or CHOEP therapy. FU guidelines in Sweden included symptom assessment, clinical examinations and blood tests at 3-4-month intervals for 2 years. FU strategies in Denmark was similar but included routine imaging, usually every 6 months for 2 years...

The aim of the study was to determine the clinical significance of EBV DNA in the peripheral blood mononuclear cells (PBMCs) from the patients with non-Hodgkin lymphoma (NHL). Newly diagnosed patients with NHL were enrolled in the study (n = 328), and clinical data retrospectively analyzed. EBV DNA was detectable in 34.8% of patients, and the positivity rate was 51.6% for T/NK cell subtype and 24.3% for B cell subtype (p < .001). In diffuse large B cell lymphoma (DLBCL), extranodal NK/T-cell lymphoma, nasal type (ENKTL), peripheral T-cell lymphoma not otherwise classified (PTCL...

PURPOSE OF REVIEW: Peripheral T cell lymphomas (PTCLs) are markedly heterogeneous at the clinical, pathological, and molecular levels. This review will discuss genetic findings in PTCL with special emphasis on how they impact lymphoma classification. RECENT FINDINGS: Sequencing studies have identified recurrent genetic alterations in nearly every PTCL subtype. In anaplastic large cell lymphoma, these studies have revealed novel chromosomal rearrangements and mutations that have prognostic significance and may suggest new therapeutic approaches...

In this review, we examine the genomic landscapes of lymphomas that arise from B, T, and natural killer cells. Lymphomas represent a striking spectrum of clinical behaviors. Although some lymphomas are curable with standard therapy, the majority of the affected patients succumb to their disease. Here, the genetic underpinnings of these heterogeneous entities are reviewed. We consider B-cell lymphomas, including Burkitt lymphoma, diffuse large B-cell lymphoma, Hodgkin lymphoma, and primary mediastinal B-cell lymphoma...

Staging of peripheral T-cell non-Hodgkin lymphoma (PTCL) is determined by 18-F FDG PET scan and bone marrow biopsy. This study addressed the accuracy of PET at detecting bone marrow (BM) involvement at restaging in patients with known involvement pretreatment. We identified patients with biopsy proven BM PTCL at diagnosis and concomitant BM and PET at the end of therapy. Pre-treatment PET demonstrated 50% (8/16) had a false-negative PET scan of the BM. After induction, repeat biopsy revealed 62.5% (10/16) with BM involvement...

Reports of sequential occurrence of two or more types of lymphoma are rare, especially when they involve different cell lineages. Herein, we report a rare case of sequential development of peripheral t-cell lymphoma following treatment of diffuse large B cell lymphoma. In a 73-year-old Chinese male patient, diffuse large B-cell lymphoma (DLBCL) was diagnosed in September 2011 based on the result of a tongue biopsy. Afterwards, he received rituximab combined with chemotherapy and local radiotherapy. Though he achieved completed remission, he had a new symptom of one enlarged left inguinal lymph node in November of 2015...

Peripheral T-cell lymphomas (PTCLs) are a rare group of lymphoid neoplasms with high relapse rates after initial therapy and poor prognosis. Most patients are aged ≥60 years and are often not candidates for aggressive salvage therapies. Romidepsin, a potent class I histone deacetylase inhibitor, has shown significant single-agent activity in relapsed/refractory PTCL. We evaluated the efficacy and tolerability of romidepsin in elderly patients in this setting. Ninety-five patients aged ≥60 years were identified from 2 prospective phase 2 registration trials of romidepsin, and comparative analyses were performed with younger patients from these trials...

Adult T-cell leukemia/lymphoma (ATL) occurs in approximately 5% of individuals infected with human T-cell leukemia virus type 1 (HTLV-1). A high proviral load (PVL; more than 4 copies per 100 peripheral blood mononuclear cells (PBMCs) or 1.6 copies per 100 blood leukocytes) and being male are risk factors for ATL development. Whether anti-HTLV-1 antibody level is related to such risk is unknown. Here, PVL and antibody levels were examined using real-time PCR and other tests in 600 HTLV-1 positive screened Japanese blood donors to understand the relationship between PVL and antibody level in asymptomatic carriers and to gain insights towards better antibody testing for HTLV-1 infection...

Malignant lymphoma is a rare form of malignancy in the uterine cervix. Most of the previously reported cases were B-cell lymphomas. We present a case of primary peripheral T-cell lymphoma, not otherwise specified, in the uterine cervix in a 49-year-old woman with a history of severe vaginal bleeding. The patient was treated with a CHOP (cyclophosphamide, adriamycin, vincristine, and prednisolone) chemotherapy regimen and 28 cycles of radiotherapy. Three months later, she presented with generalized lymphadenopathy and sudden left-eye ptosis as a complication of CNS involvement and died after 20 months from the initial disease presentation...

Introduction: Antisynthetase syndrome (ASS) is characterized by the presence of anti-Jo-1 antibodies in conjunction with clinical findings of fever, polymyositis-dermatomyositis, and interstitial lung disease (ILD). Inflammatory myopathies carry a high risk of malignancy, but this association is less well outlined in ASS. We present the case of a patient with ASS who developed non-Hodgkin's lymphoma with acute hypoxemic respiratory failure. Case Presentation: A 44-year-old female with ASS presented with acute hypoxemic respiratory failure...

Patients who undergo autologous hematopoietic stem cell transplantation (aHCT) for treatment of a relapsed or refractory lymphoma are at risk of developing therapy related- myelodysplasia/acute myeloid leukemia (t-MDS/AML). Part of the risk likely resides in inherent interindividual differences in their DNA repair capacity (DRC), which is thought to influence the effect chemotherapeutic treatments have on the patient's stem cells prior to aHCT. Measuring DRC involves identifying small differences in repair proficiency among individuals...

Lymphoma involvement of peripheral nerves is rare and it may mimic benign neurogenic tumors or neuropraxic injury. This study presents three patterns of presentations in four patients with neurolymphomatous involvement of their peripheral nerves. We reviewed the clinical records of four patients who underwent exploratory brachial plexus surgery (n = 1), pronator tunnel decompression (n = 1) and peripheral nerve exploration (n = 2) and subsequently found to have neurolymphomatosis (NL). Histological diagnoses were diffuse large B-cell lymphoma (n = 3) and NK/T-cell lymphoma (n = 1)...
