BACKGROUND: Mogamulizumab (Mog) is a defucosylated, therapeutic monoclonal antibody, targeting CCR4, and was first approved in Japan for the treatment of adult T cell leukaemia/lymphoma (ATLL), followed by cutaneous T cell lymphoma and peripheral T cell lymphoma. OBJECTIVE: To retrospectively investigate development of photosensitivity in patients with mycosis fungoides and other T cell neoplasms after treatment with Mog. METHODS: We treated 7 cutaneous lymphoma patients with Mog...

Peripheral T cell lymphomas are a heterogeneous group of post-thymic, mature lymphoid malignancies, accounting for approximately 10-15% of all non-Hodgkin's lymphomas. Hepatosplenic T-cell lymphoma (HSGDTCL) is a rare entity, which is characterized by primary extra nodal disease with typical sinusoidal or sinusal infiltration of the liver and the spleen, respectively by expression of the T-cell receptor γδ chain, and by a number of other frequent clinicopathologic features, including aggressive course of disease...

Follicular lymphoma (FL), the most common indolent B-cell non-Hodgkin lymphoma (B-NHL), is a germinal center (GC)-derived lymphoma. The mechanisms underlying B-cell differentiation/maturation in GCs could be also involved in their malignant transformation. Moreover, the non-malignant cell composition and architecture of the tumor microenvironment can influence FL development and outcome. Here, we review recent research advances on CD4 helper T cells in FL that highlight the pivotal role of T follicular helper (TFH) cells in a complex multicellular system where they interact with B cells during GC dynamics...

In recent years the combined use of chemotherapy and immunotherapy, collectively termed chemoimmunotherapy, has emerged as a promising treatment option for patients with cancer. Antibiotics are commonly used to reduce infection-related complications in patients undergoing chemotherapy. Intriguingly, accumulating evidence has implicated gut microbiota as a critical determinant of host antitumor immune responses, raising the question as to whether the use of broad-spectrum antibiotics would invariably diminish tumor response to chemoimmunotherapies...

The main role of therapy in Crohn's disease is to achieve long-term clinical remission, and to allow for normal growth and development of children. The immunomodulatory drugs used for the maintenance of remission in Crohn's disease include thiopurines (azathioprine and 6-mercaptopurine) and methotrexate. Development of hepatosplenic T-cell lymphoma in some patients with inflammatory bowel disease, treated with thiopurines independently or in combination with anti-tumor necrosis factor agents, resulted in a growing interest in the therapeutic application of methotrexate in children suffering from Crohn's disease...

AIM: Severe cardiac toxicity of doxorubicin and an immunosuppressive tumor micro-environment become main obstacles for the effective treatment of B-cell lymphoma. In this research, rituximab-conjugated and doxorubicin-loaded microbubbles (RDMs) were designed for exploring a combination approach of targeted microbubbles with ultrasound (US) irradiation and PD-1 inhibitor to overcome obstacles mentioned above. METHODS: In vivo studies were performed on SU-DHL-4 cell-grafted mice and ex vivo studies were performed on CD20+ human SU-DHL-4 cells and human T cells...

The results of conventional allogeneic stem cell transplantation (SCT) in refractory hematological malignancies are poor. Sequential strategies have shown promising results in refractory acute myeloid leukemia (AML), but have not been validated in a haploidentical (Haplo) setting. We developed a new sequential approach combining chemotherapy with broad anti-tumor activity (thiotepa 10 mg/kg, etoposide 400 mg/m2, cyclophosphamide 1600 mg/m2 from Day-15 to -10), followed after 3 days of rest by reduced-intensity conditioning regimen (fludarabine 150 mg/m2, intravenous busulfan 6...

Hepatosplenic T-cell lymphoma (HSTCL) is a rare and clinically aggressive type of T-cell lymphoma that arises most often in adolescents and young adults. Patients with HSTCL commonly present with B-symptoms and cytopenias which may suggest a diagnosis of acute leukemia initially. Patients present with extranodal disease involving the spleen, liver and bone marrow; lymphadenopathy is usually absent. The lymphoma cells can show a spectrum of cell sizes and are of T-cell lineage, often negative for CD4 and CD8 and positive for T-cell receptor γδ or, less often, αβ...

SNF5, is a core member of the SWI/SNF chromatin remodeling complex. It's deficiency leads to multiple types of aggressive cancer. Sézary syndrome, a leukemic variant of cutaneous T-cell lymphoma, is characterized by its resistance to apoptosis. Although the cause of apoptosis resistance is still poorly understood, recent evidence has revealed the importance of SATB1 in the apoptosis resistance of Sézary syndrome. In this study, we show that SNF5 is an upstream regulator of SATB1 in several conditions and that both are deficient in Sézary cells...

Therapeutic ex vivo T-cell expansion is limited by low rates and T-cell products of limited functionality. Here we describe a system that mimics natural antigen-presenting cells (APCs) and consists of a fluid lipid bilayer supported by mesoporous silica micro-rods. The lipid bilayer presents membrane-bound cues for T-cell receptor stimulation and costimulation, while the micro-rods enable sustained release of soluble paracrine cues. Using anti-CD3, anti-CD28, and interleukin-2, we show that the APC-mimetic scaffolds (APC-ms) promote two- to tenfold greater polyclonal expansion of primary mouse and human T cells compared with commercial expansion beads (Dynabeads)...

Background: While cyclophosphamide, doxorubicin, vincristine, and prednisolone (CHOP) is the most commonly used chemotherapeutic regimen for patients with peripheral T-cell lymphomas (PTCLs), elderly patients are more vulnerable to associated toxicities. We evaluated the efficacy and safety of dose-attenuated CHOP in elderly patients with PTCL. Methods: Patients with PTCL aged >70 years or 65-70-years with comorbidities were treated with dose-attenuated CHOP (cyclophosphamide: 562...

BACKGROUND: Hemophagocytosis is well known in cytotoxic cutaneous T-cell lymphomas (CTCLs), in which it may represent a sign of hemophagocytic lymphohistiocytosis syndrome (HLHS), and is also typical of cutaneous Rosai-Dorfman disease (cRDD) (without prognostic relevance). Only rarely, has cutaneous hemophagocytosis (CH) been described in other skin conditions. OBJECTIVE: To characterize the clinicopathologic features of CH in skin biopsy specimens from patients with conditions other than CTCL or cRDD...

This study aimed to investigate clinical characteristics and survival outcomes of primary cutaneous T-cell lymphoma (CTCL) in HIV-infected and non-HIV-infected patients. All data were from the Surveillance, Epidemiology, and End Results program, 1973-2013, of the U.S. National Cancer Institute. Data of 318 HIV-infected patients and 1272 non-HIV-infected patients with primary CTCL were analyzed. Endpoints were overall survival and cancer-specific mortality. Independent variables included demographics, pre-existing malignancy, treatments, and environmental factors...

Rare B-cell neoplasms with plasmablastic differentiation may aberrantly express CD3 by immunohistochemical staining, which places a great challenge for diagnosis. We here studied 17 cases of CD3+ plasmablastic B-cell neoplasms, including 12 plasmablastic lymphomas and 5 plasmablastic plasma cell myelomas. All 17 cases occurred in the extranodal sites with a male predominance (13/17). Four cases were initially misinterpreted by outside institutions, among which three were diagnosed as 'peripheral T-cell lymphoma, not otherwise specified' and one was classified as 'poorly differentiated neuroendocrine carcinoma'...

INTRODUCTION: Malignant lymphoma (ML) is a neoplasm caused by clonal expansion of undifferentiated B, T and NK-lymphoid cells. WHO classification divides lymphomas into two main types, i.e. Hodgkin lymphoma (HL), and non-Hodgkin lymphoma (NHL), with numerous subtypes. The majority of MLs are localized in lymph nodes, but extranodal locations are also possible. MLs represent approximately 3-5% of all malignant neoplasms in Poland, but their incidence has been increasing in recent years, especially in young patients...
