Article Synopsis
  • The study aimed to gather data on paroxysmal nocturnal hemoglobinuria (PNH) patients from hematology centers across Turkey to understand their clinical features and management.
  • A retrospective analysis was conducted on 60 PNH patients' medical records, revealing key demographics, symptoms, treatment responses, and survival outcomes.
  • The research found that fatigue and abdominal pain were the most common symptoms, and most patients transitioned to eculizumab treatment, with a median survival of 42 months, making this the first comprehensive review of PNH cases in Turkey.

Objective: Chronic antigenic stimulation is frequently blamed in the pathogenesis of extranodal marginal zone lymphomas including splenic marginal zone lymphoma (SMZL). Chronic hepatitis C is frequently observed in SMZL patients in some geographical regions. However, these reports are largely from North America and Europe, and data from other countries are insufficient.

RESPONSE-2 is a phase 3 study comparing the efficacy and safety of ruxolitinib with the best available therapy (BAT) in hydroxyurea-resistant/hydroxyurea-intolerant polycythemia vera (PV) patients without palpable splenomegaly. This analysis evaluated the durability of the efficacy and safety of ruxolitinib after patients completed the visit at week 80 or discontinued the study. Endpoints included proportion of patients achieving hematocrit control (< 45%), proportion of patients achieving complete hematologic remission (CHR) at week 28, and the durability of hematocrit control and CHR.

Aim: The aim of this study is to determine the immunohistochemical properties of Ki-67, P53 expression and loss of P16, and to assess their relationship with both clinical parameters and patient survival in DLBCL.

Method: Forty patients, diagnosed at the Pathology Department of our institute with nodal DLBCL were selected as the study group. The relationship between P16, P53, Ki-67 expressions and clinical and laboratory parameters like age, gender, performance status, Eastern Cooperative Oncology Group (ECOG), clinical stage, presence of B-symptoms, bone marrow involvement, International Prognostic Index (IPI) score, lactate dehydrogenase (LDH) level, extranodal extension, relapse, C-reactive protein (CRP), sedimentation, number of leukocytes in patients and patient survival were then statistically evaluated.

Background: In the pivotal RESPONSE study, ruxolitinib, a Janus kinase (JAK)1 and JAK2 inhibitor, was superior to best available therapy at controlling haematocrit and improving splenomegaly and symptoms in patients with polycythaemia vera with splenomegaly who were inadequately controlled with hydroxyurea. In this study, we assessed the efficacy and safety of ruxolitinib in controlling disease in patients with polycythaemia vera without splenomegaly who need second-line therapy.

Methods: RESPONSE-2 is a randomised, open-label, phase 3b study assessing ruxolitinib versus best available therapy in patients with polycythaemia vera done in 48 hospitals or clinics across 12 countries in Asia, Australia, Europe, and North America.
