Microenvironmental Traits of Classical Hodgkin's Lymphoma in Adolescents and Their Prognostic Impact.

Background: Classical Hodgkin's lymphoma (cHL) in adolescents between 15 and 18 years old shows a higher disease-related mortality, and the overall prognosis is worse than in both children and adults.

Objectives: We investigated the immune checkpoint inhibitors (ICPIs) therapeutic targets and specific T-regulatory and cytotoxic T-cell subsets in the subgroup of adolescent cHL patients, and we challenged their prognostic power.

Methods: We retrieved formalin-fixed paraffin-embedded (FFPE) tissue of adolescent patients diagnosed with cHL and tested by immunohistochemistry the immune checkpoint molecules CTLA-4, LAG-3, PD-1, and PDL1 as well as the biological markers FOXP3 and CD8.

Primary pulmonary T-cell lymphoproliferative disorders with a limited-stage, low proliferative index, and unusual clinical behavior: two cases of a rare occurrence.

Extranodal T-lymphoproliferative disorders or T-cell lymphomas (TLPD) are classified according to the WHO Classification (4th and upcoming 5th editions) (Swerdlow et al., IARC Press 1; Alaggio et al., Leukemia 36(7):1720-1748, 2) and to the International Consensus Classification Update (Campo et al.

TOX Expression in Mycosis Fungoides and Sezary Syndrome.

Mycosis fungoides (MF) and Sezary syndrome (SS) are the two most common type of cutaneous T-cell lymphoma (CTCL). Currently, no markers can be clearly related to prognosis or to differential diagnosis between early stages and inflammatory benign diseases (IBD). The thymocyte selection-associated high mobility group box factor (TOX), has been proposed as a possible marker in differential diagnosis between early CTCL stages and IBD.

The Impact of Cereal Grain Composition on the Health and Disease Outcomes.

Whole grains are a pivotal food category for the human diet and represent an invaluable source of carbohydrates, proteins, fibers, phytocompunds, minerals, and vitamins. Many studies have shown that the consumption of whole grains is linked to a reduced risk of cancer, cardiovascular diseases, and type 2 diabetes and other chronic diseases. However, several of their positive health effects seem to disappear when grains are consumed in the refined form.

Progression in Ph-Chromosome-Negative Myeloproliferative Neoplasms: An Overview on Pathologic Issues and Molecular Determinants.

Progression in Ph-chromosome-negative myeloproliferative neoplasms (MPN) develops with variable incidence and time sequence in essential thrombocythemia, polycythemia vera, and primary myelofibrosis. These diseases show different clinic-pathologic features and outcomes despite sharing deregulated JAK/STAT signaling due to mutations in either the Janus kinase 2 or myeloproliferative leukemia or eticulin genes, which are the primary drivers of the diseases, as well as defined diagnostic criteria and biomarkers in most cases. Progression is defined by the development or worsening of marrow fibrosis or the progressive increase in the marrow blast percentage.

Immune Microenvironment Features and Dynamics in Hodgkin Lymphoma.

Classical Hodgkin's lymphoma (cHL) accounts for 10% of all lymphoma diagnosis. The peculiar feature of the disease is the presence of large multinucleated Reed-Sternberg and mononuclear Hodgkin cells interspersed with a reactive microenvironment (ME). Due to the production of a large number of cytokines, Hodgkin cells (HCs) and Hodgkin Reed-Sternberg cells (HRSCs) attract and favour the expansion of different immune cell populations, modifying their functional status in order to receive prosurvival stimuli and to turn off the antitumour immune response.

The diagnostic role of Next Generation Sequencing in uncovering isolated splenomegaly: A case report.

Many diseases can induce splenomegaly, however, about 5% of splenomegalies are idiopathic. When there is no underlying treatable cause, and the splenomegaly significantly affects the quality of life, splenectomy is the best therapeutic choice. A 67-year-old woman had idiopathic and asymptomatic splenomegaly.

Role of chromatin assembly factor-1/p60 and poly [ADP-ribose] polymerase 1 in mycosis fungoides.

Mycosis fungoides (MF) represents the most common type of cutaneous lymphoma. In the majority of patients, the disease has a slow evolution and a protracted course; however, a subset of patients shows poor oncologic outcomes. Unfortunately, there are no reliable prognostic markers for MF, and the currently available treatments are only effective in a minority of patients.

Prognostic significance of Bcl-2 expression in primary cutaneous B-cell lymphoma: a reappraisal.

Bcl-2 family protein plays an important role in apoptosis and its overexpression is protects neoplastic cell from apoptotic stimuli. Cutaneous B-cell lymphoma are rare non-Hodgkin lymphomas and can be classified in primary forms, featuring an exclusive skin-involvement at diagnosis, and cutaneous spread of a nodal disease. Such a distinction is not trivial, owing to different prognosis (indolent vs.
