Blood-Brain Barrier Disruption (BBBD)-Based Immunochemotherapy for Primary Central Nervous System Lymphoma (PCNSL), Early Results of a Phase II Study.

Primary central nervous system lymphoma is a rare but aggressive brain malignancy. It is associated with poor prognosis even with the current standard of care. The aim of this study was to evaluate the effect and tolerability of blood-brain barrier disruption treatment combined with high-dose treatment with autologous stem cell transplantation as consolidation on primary central nervous system lymphoma patients.

Chronic Cutaneous Disorders Are Associated with a More Favorable Disease Presentation and Outcome in Patients with Hodgkin Lymphoma.

Introduction: In epidemiological studies, chronic inflammation or previous major infection have revealed to be associated with an increased risk of developing Hodgkin lymphoma (HL). The association of chronic inflammation with the disease outcome is poorly defined. In this retrospective study based on 92 consecutive HL patients, we explored the incidence of previous inflammatory processes or previous major infection in newly diagnosed HL patients and their association with treatment outcome.

Strong Prolyl Hydroxylase Domain 1 Expression Predicts Poor Outcome in Radiotherapy-treated Patients with Classical Hodgkin's Lymphoma.

Background: Hypoxia-inducible factors (HIFs) and prolyl hydroxylase domain (PHD) proteins control cellular oxygen homeostasis and a wide range of other processes.

Materials And Methods: We immunohistochemically assessed the expression of HIF1α, HIF2α, PHD1, PHD2 and PHD3 in 115 cases of classical Hodgkin's lymphoma, all treated in the first line with doxorubicin, bleomycin, vinblastine and darcabazine (ABVD) chemotherapy.

Results: In advanced-stage patients treated with involved-field radiotherapy (IFRT), nuclear HIF1α expression in reactive cellular infiltrate predicted prolonged relapse-free survival (RFS) (p=0.

Low Rap1-interacting factor 1 and sirtuin 6 expression predict poor outcome in radiotherapy-treated Hodgkin lymphoma patients.

Sirtuins (SIRTs) are a family of histone deacetylases, which widely regulate cellular metabolism and are also involved in DNA repair. Rap1-interacting factor 1 (Rif1) and O-alkylguanine DNA alkyltransferase (MGMT) are DNA-repair enzymes, which may potentially be involved in resistance to treatment of classical Hodgkin lymphoma (HL). We assessed the expression levels of (previously unstudied) SIRT1, SIRT4, SIRT6, Rif1, and MGMT immunohistochemically in 85 patients with untreated classical HL.

Strong KDM4B and KDM4D Expression Associates with Radioresistance and Aggressive Phenotype in Classical Hodgkin Lymphoma.

Background: Epigenetic regulators, including Jumonji domain 2 (JMJD2/KDM4) proteins are involved in post-translational modification of histone demethylation and have a major role in carcinogenesis of many solid tumors.

Materials And Methods: We assessed immunohistochemically the expression of lysine (K)-specific demethylase 4 (KDM4)A, KDM4B and KDM4D in tumors from 91 patients of adriamycin, bleomycin, vinblastine, darcabazine (ABVD)-treated classical Hodgkin lymphoma.

Results: Strong cytoplasmic KDM4B expression in the reactive cellular infiltrate and also in Reed-Sternberg (RS) cells predicted poor relapse-free survival (RFS) (p=0.

Oxidative stress markers and mitochondrial antioxidant enzyme expression are increased in aggressive Hodgkin lymphomas.

Aims: Hodgkin lymphoma treatments are largely based on the generation of reactive oxygen species, but increased expression of antioxidant enzymes may contribute to chemoresistance. The aims of this study were: to define the extent and prognostic value of oxidative stress marker and antioxidant enzyme expression in Hodgkin lymphomas; and to investigate a potential association between antioxidant enzymes and chemoresistance.

Methods And Results: We immunohistochemically assessed expression of peroxiredoxin (Prx) II, Prx III, Prx V, Prx VI, manganese superoxide dismutase (MnSOD), 8-hydroxydeoxyguanosine (8-OHdG) and nitrotyrosine in 99 cases of uniformly treated Hodgkin lymphoma.
