    Deferasirox in children with transfusion-dependent thalassemia or sickle cell anemia: A large cohort real-life experience from Turkey (REACH-THEM)
    (Wiley, 2019) Antmen, Bulent; Karakas, Zeynep; Yesilipek, Mehmet Akif; Kupesiz, Osman Alphan; Sasmaz, Ilgen; Uygun, Vedat; Kurtoglu, Erdal
    Objectives To evaluate the long-term efficacy and safety of deferasirox therapy in a large observational cohort of children with transfusion-dependent thalassemia (TDT) and sickle cell anemia (SCA) in Turkey. Methods This was a multicenter, prospective cohort study including TDT and SCA patients aged 2-18 years with iron overload (>= 100 mL/kg of pRBC or a serum ferritin [SF] level >1000 mu g/L) receiving deferasirox. Patients were followed for up to 3 years according to standard practice. Results A total of 439 patients were evaluated (415 [94.5%] TDT, 143 [32.6%] between 2 and 6 years). Serum ferritin levels consistently and significantly decreased across 3 years of deferasirox therapy from a median of 1775.5 to 1250.5 mu g/L (P < 0.001). Serum ferritin decreases were noted in TDT (1804.9 to 1241 mu g/L), SCA (1655.5 to 1260 mu g/L), and across age groups of 2-6 years (1971.5 to 1499 mu g/L), 7-12 years (1688.5 to 1159.8 mu g/L), and 13-18 years (1496.5 to 1107 mu g/L). Serum ferritin decreases were also noted for all deferasirox dose groups but only significant in patients with doses >= 30 mg/kg/d (n = 120, -579.6 median reduction, P < 0.001). Only 9 (2%) patients had adverse events suspected to be related to deferasirox. Serum creatinine slightly increased but remained within the normal range. Conclusions Deferasirox has long-term efficacy and safety in children with TDT and SCA, although higher doses (>= 30 mg/kg/d) may be required to achieve iron balance.

    Patient characteristics and management practices in chronic myeloid leukemia in Turkey: reflections from an expert meeting
    (Taylor & Francis Ltd, 2022) Eskazan, Ahmet Emre; Ali, Ridvan; Alnigenis, Ebru; Ayyildiz, Orhan; Haznedaroglu, Ibrahim; Kirkizlar, Onur; Kurtoglu, Erdal
    Introduction The therapeutic landscape of chronic myeloid leukemia (CML) has evolved significantly since the introduction of imatinib. The European LeukemiaNet (ELN) recommendations serve as a guide for diagnosis, treatment, and monitorization of CML, but availability and accessibility of diagnostic tools and medications affect their applicability. Areas covered This article provides an overview of the current clinical management of CML in Turkey with reference to the key outputs of the online expert meeting held in November 2020. The applicability of the ELN 2020 recommendations for treating CML in clinical practice was also discussed. Expert opinion Imatinib is the only reimbursed and the most preferred first-line treatment in CML restricting the upfront use of second-generation tyrosine kinase inhibitors (TKIs), thereby limiting the applicability of treatment-free remission approach in Turkey. The ELN recommendations about using the EUTOS Long-Term Survival (ELTS) score for risk assessment and focusing on patient reported outcomes and quality of life can be enhanced with educational activities. The widespread availability of standardized technical infrastructure for diagnosing and monitoring CML will contribute to better disease management. Establishing a sustainable national database for CML is valuable for observing patient characteristics and disease outcomes as well as the impact of treatment patterns over time.
