Article Synopsis
- Patients with chronic lymphocytic leukemia (CLL) have a significantly heightened risk of developing other malignancies (OMs), with a study tracking nearly 20,000 CLL patients revealing 3,513 OMs diagnosed over 129,254 years of follow-up.
- The study found that treatment with fludarabine and cyclophosphamide increased the likelihood of developing myelodysplastic syndrome (MDS) and acute myeloid leukemia (AML), while non-melanoma skin cancer (NMSC) and prostate cancer were common solid tumors in treated patients.
- Importantly, patients with CLL who developed OMs had lower overall survival rates, especially those diagnosed with AML and MDS, highlighting that C
Background: Patients with chronic lymphocytic leukemia (CLL) may be more susceptible to COVID-19 related poor outcomes, including thrombosis and death, due to the advanced age, the presence of comorbidities, and the disease and treatment-related immune deficiency. The aim of this study was to assess the risk of thrombosis and bleeding in patients with CLL affected by severe COVID-19.
Methods: This is a retrospective multicenter study conducted by ERIC, the European Research Initiative on CLL, including patients from 79 centers across 22 countries.
Background: The Wnt/β-catenin signalling is aberrantly activated in primary B cell chronic lymphocytic leukaemia (CLL). Epigenetic silencing of pathway inhibitor genes may be a mechanism for its activation. In this study, we investigated systematically and quantitatively the methylation status of 12 Wnt/β-catenin pathway inhibitor genes - CDH1, DACT1, DKK1, DKK2, DKK3, DKK4, SFRP1, SFRP2, SFRP3, SFRP4, SFRP5 and WIF1 - in the cell lines EHEB and MEC-1 as well as patient samples.
