Outcome of malignant lymphoma in Ukraine. Analysis of 563 cases registered in the Ukrainian Lymphoma Registry in 2019-2021.

We report the outcome of 563 cases of newly diagnosed lymphoma registered in 2019-2021, including 176 cases (31.2%) of Hodgkin lymphoma (HL), 130 (23.1%) of diffuse large B-cell lymphoma (DLBCL), 28 (5%) of follicular lymphoma (FL), 16 (2.

18F-FDG PET/CT Cannot Substitute Endoscopy in the Staging of Gastrointestinal Involvement in Mantle Cell Lymphoma. A Retrospective Multi-Center Cohort Analysis.

The detection of gastrointestinal (GI) involvement in Mantle Cell Lymphoma is often underestimated and may have an impact on outcome and clinical management. We aimed to evaluate whether baseline 18F-FDG PET/CT presents comparable results to endoscopic biopsy in the diagnosis of GI localizations. In our retrospective cohort of 79 patients, sensitivity and specificity of 18F-FDG PET/CT were low for the stomach, with a fair concordance ( = 0.

Five-year survival follow-up of a phase III randomised trial comparing ofatumumab versus physicians' choice for bulky fludarabine-refractory chronic lymphocytic leukaemia: a short report.

In 2014, an interim analysis of a phase 3 study was performed to evaluate the effectiveness of ofatumumab in patients with bulky fludarabine-refractory chronic lymphocytic leukaemia (BFR CLL) as compared to physician's choice. The five-year follow-up of this phase 3 trial showed that ofatumumab therapy resulted in a numerically but not significantly longer overall survival. As only few patients had the chance to receive a kinase inhibitor later, the study displays the survival of BFR CLL patients in the period prior to receiving small-molecule inhibitors.

MAPK/ERK signal pathway alterations in patients with Langerhans Cell Histiocytosis.

Background: Clinical outcomes of Langerhans cell histiocytosis (LCH) are highly variable. It has been suggested that mitogen-activated protein kinase (MAPK) /extracellular signal-regulated kinases (ERK) signaling pathway might be activated in LCH patients.

Materials And Methods: We investigated KRAS, BRAF and NRAS mutations in patients with LCH by qPCR.
