Morphological analysis of patellofemoral joint in haemophilic arthropathy: A case-control study.

INTRODUCTION: Knees affected by haemophilic arthropathy exhibit distinct differences in both bone morphology and soft tissue behaviour. This study aims to analyse the morphological characteristics of the distal femur and patellofemoral joint in patients with haemophilia in comparison to normal healthy population. MATERIAL AND METHODS: Study was conducted as pair-matched case-control study with 43 individuals in both the haemophilia group and the control group. Patellar luxation, patellar tilt (PT), length of the patella in both axis (pAP, pML), depth and angle of trochlear sulcus (SD, SA), lateral trochlear inclination (LTI), medial and lateral femoral facet length (mFL, LFL), intercondylar depth (ID), transepicondylar axis (TEA) and lateral condyle length (LCL) were assessed on knee MRI. Correlation between Pettersson score and measured variables were also analysed. RESULTS: PT was medial sided in 10 (23.2%) cases in haemophilic group. Mean values of pAP, pML, PT were significantly lower in haemophilia group (p < .001, p: .007, p = .001 respectively). There were no significant changes in SA (p = .628), SD (p = .340), LTI (p = .685), LFL (p = .241) and MFC-LFC (p = .770) whilst mFL was significantly longer in haemophilia group (p = .009). ID (p < .001), TEA (p = .007) and LCL (p = .001) were all shorter in haemophilia group. Pettersson score was inversely correlated with pAP, pML, ID, TEA, LCL, pML/SA and ID/LCL. CONCLUSION: Morphological changes in haemophilic arthropathy involve a smaller and medially-tilted patella, narrowed lateral condyle and transepicondylar axis, combined with reduced intercondylar depth. These alterations must keep in mind especially in pre- and intraoperative assessments for arthroplasty procedures.

Results of multicenter registry for patients with inherited factor VII deficiency in Turkey.

INTRODUCTION: Inherited factor VII (FVII) deficiency (FVIID) is the most common of inherited rare bleeding disorders. Other determinants of clinical severity apart from FVII level (FVIIL) include genetic and environmental factors. We aimed to identify the cut-off FVIILs for general and severe bleedings in patients with FVIID by using an online national registry system including clinical, laboratory, and demographic characteristics of patients. METHODS: Demographic, clinical, and laboratory data of patients with FVIID extracted from the national database, constituted by the Turkish Society of Hematology, were examined. Bleeding phenotypes, general characteristics, and laboratory features were assessed in terms of FVIILs. Bleeding rates and prophylaxis during special procedures/interventions were also recorded. RESULTS: Data from 197 patients showed that 46.2% of patients had FVIIL< 10%. Most bleeds were of mucosal origin (67.7%), and severe bleeds tended to occur in younger patients (median age: 15 (IQR:6-29)). Cut-off FVIILs for all and severe bleeds were 16.5% and 7.5%, respectively. The major reason for long-term prophylaxis was observed as central nervous system bleeding (80%). CONCLUSION: Our data are consistent with most of the published literature in terms of cut-off FVIIL for bleeding, as well as reasons for prophylaxis, showing both an increased severity of bleeding and younger age at diagnosis with decreasing FVIIL. However, in order to offer a classification similar to that in Hemophilia A or B, data of a larger cohort with information about environmental and genetic factors are required.

The value of ultrasonography in detecting early arthropathic changes and contribution to the clinical approach in patients of hemophilia.

PURPOSE\AIM: Hemophilia affects the blood clotting process, is a genetic disease characterized by recurrent bleeding. The hemophilia early arthropathy detection with ultrasound (HEAD-US) procedure and scoring method were designed for the detection of early changes in affected joints of patients. In this article, it was aimed to detect early arthropathic changes in the joints of hemophilia patients with the HEAD US scoring system and to investigate its clinical contribution. It was aimed to investigate the effectiveness of HEAD-US scoring in showing early joint damage in subclinical hemophilia cases and its contribution to treatment. METHODS: The present study included 50 hemophilia patients who were admitted to Departments of Pediatric and Adult Hematology for routine follow-up. During routine follow-up controls, patients were scored by physical examination and HJHS 2.1 and by ultrasonography and HEAD US. Statistical tests were used to analyze joint health status and the results of US examination in the patient group. RESULTS: A total of 294 joints (elbow n = 100, knee n = 94, ankle n = 100) were evaluated by ultrasonography. The mean HJHS and HEAD-US scores of the patients were 14.94 ± 15.18 and 15.6 ± 12.6, respectively. CONCLUSIONS: HEAD-US is accepted to be more sensitive than HJHS in detecting early signs of arthropathy. Detection of early abnormalities by ultrasonography will enable the development of individualized treatment protocols and to the prevention of arthropathy development.

Efficacy and safety of ruxolitinib in patients with myelofibrosis: a retrospective and multicenter experience in Turkey

Background/aim: The aim of this study is to assess the efficacy and safety of ruxolitinib in patients with myelofibrosis. Materials and methods: From 15 centers, 176 patients (53.4% male, 46.6% female) were retrospectively evaluated. Results: The median age at ruxolitinib initiation was 62 (28­87) and 100 (56.8%) of all were diagnosed as PMF. Constitutional symptoms were observed in 84.7%. The median initiation dose of ruxolitinib was 30 mg (10­40). Dose change was made in 69 (39.2%) patients. Forty seven (35.6%) and 20 (15.2%) of 132 patients had hematological and nonhematological adverse events, respectively. The mean spleen sizes before and after ruxolitinib treatment were 219.67 ± 46.79 mm versus 199.49 ± 40.95 mm, respectively (p < 0.001). There was no correlation between baseline features and subsequent spleen response. Overall survival at 1-year was 89.5% and the median follow up was 10 (1­55) months. We could not show any relationship between survival and reduction in spleen size (p = 0.73). Conclusion: We found ruxolitinib to be safe, well tolerated, and effective in real-life clinical practice in Turkey. Ruxolitinib dose titration can provide better responses in terms of not only clinical benefit but also for long term of ruxolitinib treatment.

The effect of malnutrition on mortality in hospitalized patients with hematologic malignancy.

OBJECTIVES: The aim of this study was to assess the association between malnutrition status with the (Global Leadership Initiative on Malnutrition) GLIM criteria and 1-year mortality in hospitalized patients with hematologic malignancy. METHODS: This study included 120 hospitalized patients with hematologic malignancy. Patients who were at risk of malnutrition with NRS2002 were reevaluated with the GLIM criteria for defined malnutrition. Also, the mid-upper arm circumference (MUAC), calf circumference (CC), and handgrip (HG) were measured, and albumin, C reactive protein (CRP), and total protein were recorded to assess malnutrition-related factors. RESULTS: A total of 120 patients are with lymphoma, leukemia, and myeloma having a rate of 34.2%, 34.2%, and 31.6%, respectively, and risk of malnutrition with NRS2002 was established in 82% of patients. Malnutrition with GLIM criteria was seen in 25.8% of patients. The 1-year mortality rate was 41.7% (n = 50). Malnutrition was associated with higher mortality risk independently with age and duration of diagnosis (HR 3.55 (1.99-6.34), p = 0.001). Low HG (HR 0.51 (0.26-0.99), p = 0.03), low albumin (HR 0.39 (0.2-0.6), p = 0.001), and high CRP (HR 2.39 (1.36-4.20), p = 0.002) were significantly associated with increased mortality risk. In contrast, BMI, MUAC, FFMI, and CC were not associated with higher mortality. CONCLUSION: Malnutrition is high with the GLIM criteria. Hospitalized patients with hematologic malignancy with malnutrition have a higher 1-year mortality risk.

Study for the Diagnostic Screening of Paroxysmal Nocturnal Hemoglobinuria in Older Patients with Unexplained Anemia and/or Cytopenia.

BACKGROUND: Paroxysmal nocturnal hemoglobinuria (PNH) is a rare acquired hematopoietic stem cell disease that may lead to weakness and death of patients, if unrecognized and untreated. Although consensus guidelines were reviewed recently for the diagnostic screening of PNH with multi-parameter flow cytometry (FCM), until now, no study has investigated the efficiency of such clinical indications in older patients. METHODS: Overall, 20 centers participated in the study and a total of 1,689 patients were included, 313 of whom were at geriatric age and 1,376 were aged 18 - 64 years. We evaluated the efficiency of consensus clinical indications for PNH testing using FCM in peripheral blood samples and compared the results of older patients and patients aged 18 - 64 years. RESULTS: PNH clones were detected positive in 7/313 (2.2%) of the older patients. Five (74.4%) of the patients with PNH clones had aplastic anemia, 1 had unexplained cytopenia, and 1 patient had myelodysplastic syndrome (MDS) with refractory anemia. PNH clones were not detected in any older patients who were screened for unexplained thrombosis, Coombs (-) hemolytic anemia, hemoglobinuria, and others (e.g., elevated lactate dehydrogenase (LDH), splenomegaly). We detected PNH clones in 55/1376 (4%) samples of the patients aged under 65 years. Forty-two (76.4%) patients with PNH clones had aplastic anemia, 2 patients had Coombs (-) hemolytic anemia, 3 patients had unexplained cytopenia, 1 patient had MDS with refractory anemia, 1 patient had hemoglobinuria, and 6 (10.9%) had others (e.g., elevated LDH, splenomegaly). PNH clones were not detected in any patients who were screened for unexplained thrombosis. There was no statistical difference between the geriatric population and patients aged 18 - 64 years in terms of clinical indications for PNH screening with FCM (p = 0.49). CONCLUSIONS: Our results showed that the current clinical indications for PNH screening with FCM were also efficient in older patients. We suggest that older patients with unexplained anemia, myelodysplastic syndrome with refractory anemia, and unexplained cytopenia should be screened for PNH with FCM to identify patients who would benefit from treatment.

Study for the diagnostic screening of paroxsymal nocturnal hemoglobinuria in Turkey: Prospective multicentric evaluation of suspected patients.

BACKGROUND: Paroxysmal nocturnal hemoglobinuria (PNH) is a rare disease presenting with variable and various clinical findings. PNH might be overlooked and diagnosis may be delayed due to low awareness about PNH. This is the first multicenter study in Turkey, investigating the efficiency of diagnostic screening of PNH by multiparameter flow cytometry (FCM) according to consensus guidelines. METHODS: We evaluate the efficiency of consensus clinical indications for PNH testing with FCM in 1689peripheral blood samples from 20 centers between January 2014 and December 2017. RESULTS: Overall, at the 20 centers contributing to this study, PNH clone were detected in 62/1689 samples (3.6%) by FCM test. 75.8% (n = 47) of patients with PNH clone had aplastic anemia, 3.2% (n = 2) had Coombs (-) hemolytic anemia, 6.5% (n = 4) had unexplained cytopenia, 3.2% (n = 2) had MDS with refractory anemia, 1.6% (n = 1) had hemoglobinuria and 9.7% (n = 6) had others (elevated LDH, splenomegaly, etc.). In contrast, we detect no PNH clone test in patients who were screened for unexplained thrombosis. CONCLUSIONS: Our study showed that current clinical indications for PNH testing are highly efficient and diagnostic screening of suspected patients for PNH with FCM is recommended. However, advanced screening algorithms are required for patients presenting with unexplained thrombosis and normal complete blood count.

Nodular lymphocyte predominant Hodgkin's lymphoma in daily practice: A multicenter experience.

Nodular lymphocyte predominant Hodgkin's lymphoma (NLPHL) is a rare subtype of Hodgkin's lymphoma. In this study, we aimed to investigate the clinical features and therapeutic outcomes of patients with NLPHL who were diagnosed at different institutes in Turkey. We retrospectively reviewed the records of the patients diagnosed with NLPHL. Adult patients who were diagnosed after 2005 with histological confirmation were selected for the study. Forty-three patients were included in the study. Median age of patients was 37.5 years (18-70) at the time of diagnosis. About 60.5% patients were diagnosed as stage I and II NLPHL, and remaining 39.5% had stage III and IV disease. Median follow-up was 46 months. During follow-up, none of the patients died. Seven patients relapsed or progressed after initial therapy at a median of 12 months. Five of 7 relapsed/refractory patients (71.4%) were salvaged with chemotherapy only (DHAP, ICE), and the remaining 2 (28.6%) were salvaged with chemoimmunotherapy. All of relapsed/refractory patients were able to achieve complete remission after salvage therapy. Lactate dehydrogenase levels were significantly higher in patients with progressive disease compared with nonprogressive disease. Our study showed an excellent outcome with all patients alive at last contact with a median follow up of 46 months despite a wide range of different therapeutic approaches. All relapsed and refractory patients were successfully salvaged despite a low frequency of patients received immunotherapy in conjunction with chemotherapy. Our results suggest that immunotherapy may be reserved for further relapses.

Efficacy and safety of lenalidomide and dexamethasone in patients with relapsed/ refractory multiple myeloma: a real-life experience

Background/aim: In Turkey, lenalidomide plus dexamethasone (RD) has been used to treat relapsed/refractory multiple myeloma (RRMM) since 2010. This retrospective, single-center study evaluated the efficacy and tolerability of RD in patients with RRMM between October 2010 and June 2016. Materials and methods: Patients' records were reviewed, and overall (OS) and progression-free survival (PFS) were assessed. Results: One hundred and twenty patients (71 males; 59.2%) were included in the study. The median number of prior lines of treatment was one (1­4); 72 patients (60.0%) received RD as second-line therapy and 51 patients (42.5%) had previously undergone autologous stem cell transplantation (ASCT). The overall response rate was 72.5%, with 19% of these patients achieving a complete response. The median length of follow-up and duration of response to RD was 14 months and 19 months, respectively. Median OS and PFS were 32 and 21 months, respectively. Prior ASCT, an overall response, and treatment with RD for >12 cycles were identified as independent prognostic factors for OS and PFS. Adverse events (AEs) occurred in 69 (57.5%) and 14 patients (11.7%) discontinued treatment due to AEs. Conclusion: We found RD to be safe, well tolerated, and effective in RRMM in everyday clinical practice in Turkey.

Risk factors for poor mobilization in solid tumors: How effectively can we mobilize patients with solid tumors?

BACKGROUND: In the literature, risk factors for poor mobilization were tried to identify. However, most of the studies consisted heterogeneous group of patients including both hematologic and oncologic malignancies. In this study, we aimed to identify the risk factors for poor mobilization in adults with solid tumors. METHODS: We enrolled 49(47 men, 2 women) adult patients with solid tumor who were mobilized between September 2007 and February 2017. All the mobilization procedures were performed with G-CSF(10µg/kg/day) with chemotherapy. Mobilization insufficiency was defined as peripheral blood CD34+stem cell number less than 10/µl and/or total collected CD34+cells less than 2.5×10 6/kg. RESULTS: The patients were divided into two groups, patients with successful mobilization at the first attempt(group 1, 36 patients,73.5%) and poor mobilizers (group 2, 13 patients 26.5%). Second and third mobilization attempt was needed in 11 and 2 patients, respectively. The median number of CD34+cells collected was 7,08×106/kg(0,6-19) with a median 4(1-6) apheresis. There was no statistical difference between two groups in terms of patient's and mobilization characteristics. Only number of CD 34+stem cells collected was statistically different (median 9,07×106/kg CD34+cells in group 1 versus 2,14×106/kg in group 2, p<0.05). The only possible risk factor that we could define was presence of organ metastasis. CONCLUSIONS: Since several methods and new drugs are available for peripheral stem cell collecting, risk factors should be identified clearly in adult population with solid tumors. So multicenter studies should be constructed for resolving this problem.

Epidemiology and analysis of invasive fungal infections in patients withhematological malignancies: a single-center real-life experience

Background/aim: Invasive fungal infection (IFI) causes morbidity and mortality among patients with hematological malignancies. We evaluated the incidence and treatment characteristics of IFIs between October 2012 and December 2013. Materials and methods: Patients who received chemotherapy or stem cell transplantation were retrospectively evaluated. Fungal infections were classified according to EORTC criteria.Results: Prophylaxis and antifungal therapy were given in 30.5% and 23.6% of 522 chemotherapy courses, respectively. The incidence of proven/probable IFI was 6.7%. The incidence of IFI among patients who received prophylaxis was significantly higher than among those who did not receive it (11.3% vs. 4.6%, P = 0.005). There was no significant difference between patients who received mold-active and no mold-active prophylaxis (P = 0.098). The most common single agent therapy and causative pathogen was liposomal amphotericin B (57.1%) and Aspergillus (n = 5), respectively. IFI-attributable mortality rate was 14.2% in 6 weeks.Conclusion: The IFI incidence and mortality rate were similar to that reported in the literature. The IFI rate was higher in the group using prophylaxis, as this is a high-risk group. Although the IFI rate was not significantly different between groups using prophylaxis, patients should be followed closely for the effective use of posaconazole prophylaxis.

Prevalence of anemia and malnutrition and their association in elderly nursing home residents.

PURPOSE: Malnutrition is one of the most important geriatric syndromes in the elderly. The aim of this study was to investigate the association between anemia and malnutrition in elderly nursing home residents. MATERIALS AND METHODS: Local nursing home residents over 60 years old in the Izmir were included in the study. Blood samples were taken from study participants for hemogram, iron, ferritin, total iron-binding capacity, vitamin B12 and folic acid analysis. WHO criteria were used to define anemia. Causes of anemia were classified as iron deficiency, vitamin B12 or folic acid deficiency, anemia of chronic disease or other hematologic causes. Anemia was defined as the dependent variable and malnutrition was defined as the independent variable. Correlation between MNA scores and Hb levels was determined using Pearson correlation analysis. The slope of causality between malnutrition and anemia was determined using the χ (2) test and logistic regression analysis. RESULTS: The study included 257 elderly nursing home residents with a mean age of 78.5 ± 7.8 years. The overall prevalence of anemia was 54.9 %; 35.8 % of the study participants were at risk of malnutrition and 8.2 % were malnourished. Anemia risk was 2.12-fold higher in participants at risk of malnutrition and 5.05-fold higher in those with malnutrition. In the participants with malnutrition or malnutrition risk, the most common cause of anemia was anemia of chronic disease (57.1 and 46.5 %, respectively). CONCLUSION: The prevalence of anemia among elderly nursing home residents is high in Turkey. Malnutrition and malnutrition risk increase the incidence of anemia.

Toxic epidermal necrolysis associated with radiotherapy and phenytoin in a patient with non-Hodking's lymphoma: A case report.

Toxic epidermal necrolysis (TEN) is a disease which is characterized by fever and desquamation of the skin and mucosal membranes. It is usually related with drugs, especially aromatic anticonvulsants which are recognized as the most common cause of this disorder. Cranial irradiation may act as a precipitating factor along with anticonvulsants for the development of TEN. We report a 28-year-old patient with central nervous system (CNS) relapsed non-Hodgkin lymphoma (NHL) who developed TEN after cranial radiotherapy and concurrent phenytoin treatment.

Peripheral blood stem cell mobilization from healthy donors.

Most frequently used graft of hematopoietic stem cells (HSCs) for allogeneic transplantation is peripheral blood stem cells (PBSCs) that are collected after mobilization with frequently granulocyte colony-stimulating factor (G-CSF). Administration of the optimal dose of G-CSF while preserving the donor health is one of the most important points for sufficient PBSC mobilization and harvest. We hereby tried to summarize characteristic features, potential side effects and main topics in peripheral blood stem cell mobilization from healthy donors.

Can an oral antidiabetic (rosiglitazone) be of benefit in leukemia treatment?

PPARs are ligand-regulated transcription factors and regulate expression of several gene products. Therefore, PPARs are being studied for their possible contribution to the treatment of cancer, atherosclerosis, inflammation, infertility and demyelinating diseases. Primary AML patients were observed to have significantly elevated PPARγ mRNA expression compared to normal peripheral blood or bone marrow mononuclear cells. This study investigated the cytotoxic effects of rosiglitazone maleate, a pure PPARγ agonist, in vitro in HL-60 cell line. This study obtained results which can provide guidance for future studies. Whether the PPARy agonist rosiglitazone maleate may provide additive effects in refractory or relapsing cases of acute leukemia may be set as an objective for the future studies.

Bortezomib induces apoptosis by interacting with JAK/STAT pathway in K562 leukemic cells.

In the current study, we aimed to identify the cytotoxic and apoptotic effects of bortezomib (BOR) on human K562 chronic myelogenous leukemia cells and to evaluate the potential roles of Janus kinase/signal transducers and activators of transcription (JAK/STAT) pathway members STAT3, STAT5, and JAK2 on BOR-induced cell death of leukemic cells. Cell viability was assessed via trypan blue dye exclusion test, and cytotoxicity of the BOR-treated cells was conducted by 2,3-bis(2-methoxy-4-nitro-5-sulphophenyl)-2H-tetrazolium-5-carboxanilide inner salt (XTT) assay. The relative messenger RNA (mRNA) expression levels of STAT3, STAT5A, STAT5B, and JAK2 were analyzed by quantitative reverse transcriptase-polymerase chain reaction (qRT-PCR). On the other hand, their protein expression levels were detected by western blot method. The obtained results indicated that BOR treatment reduced cell viability and induced leukemic cell apoptosis in a dose- and time-dependent manner as compared to untreated control cells. While mRNA expression levels of STAT5A, STAT5B, and STAT3 were significantly reduced following BOR treatment when compared to untreated controls, it had no effect upon JAK2 mRNA expression. As for protein levels, STAT expressions were downregulated after BOR treatment especially at 72nd and 96th hours. Our results pointed out that BOR treatment had a significant potential of being an anticancer agent for chronic myelogenous leukemia therapy, and this effect could be due to the expressional downregulations of JAK/STAT pathway members.

Management of Primary Immune Thrombocytopenia - Turkish Modified Delphi-Based Consensus Statement for Special Considerations.

Introduction: Primary immune thrombocytopenia (ITP) is an acquired disorder of platelets with complex and unclear mechanism of increased immune distruction or impaired production of platelets. While management of ITP is evolving, there is a need for guidance particularly in certain circumstances such as pregnancy, emergency and for patients requiring co-medications. We aimed to determine the tendencies of hematologists in Turkiye on such special conditions. Methods: As a modified Delphi method, Turkish National ITP Working Group founded under Turkish Society of Hematology developed a questionnaire consisting of statements regarding pregnancy, emergency and circumstances regarding co-treatment with antiaggregant or anticoagulants. 107 Hematologists working either in university or state hospitals voted for their agreement or disagreement of the statements for two consequential rounds. Results: Participant hematologists reached an agreement on the starting treatment in pregnant patients with platelets less than 30 x109/L and delivery of either normal or cesarian section to be safely performed above 50 x109/L. For emergency and rescue management of ITP, our panel have agreed against the use of high dose corticosteroids alone, preferred a combination with transfusion or IVIG. For patients who require interventions, platelet counts >50 x109/L were regarded as safe for low risk procedures as well as co-treatment with antiplatelets or anticoagulants. Conclusion: As National ITP study group, we have observed the need to increase the practice guidance in patients with primary ITP requiring additional treatments including invasive interventions, and co-treatments towards coagulation. Decisions on the management of ITP during pregnancy should be individualized. There is a certain lack of consensus on the thresholds of platelet counts as well as co-morbidities and co-medications. This lack of consensus may be due to the variations in the practices.

Management of Adult Primary Immune Thrombocytopenia: Delphi-Based Consensus Recommendations

Objective: Primary immune thrombocytopenia (pITP) is an acquired autoimmune disorder related to the increased destruction and/or impaired production of platelets. Its diagnosis and management are challenging and require expertise and the interpretation of international consensus reports and guidelines with national variations in availability. We aimed to assess the agreement of hematologists in Türkiye on certain aspects of both first-line and second-line management of patients with pITP. Materials and Methods: Applying a modified Delphi method, the Turkish National ITP Working Group (14 steering committee members), founded under the auspices of the Turkish Society of Hematology, developed a 21-item questionnaire consisting of statements regarding the first-line and second-line treatment of pITP. A total of 107 adult hematologists working in either university or state hospitals voted for their agreement or disagreement with the statements in two consecutive rounds. Results: The participants reached consensus on the use of corticosteroids as first-line treatment and with limited duration. Methylprednisolone was the corticosteroid of choice rather than dexamethasone. Use of intravenous immunoglobulin was not preferred for patients without bleeding. It was also agreed that thrombopoietin receptor antagonists (TPO-RAs) or rituximab should be recommended as second-line treatment and that splenectomy could be considered 12-24 months after diagnosis in patients with chronic pITP. Conclusion: The optimization of the dose and duration of TPO-RAs in addition to corticosteroids is necessary to improve the management of patients with pITP.

Quality of life and supportive care in multiple myeloma.

UNLABELLED: Multiple myeloma is the second most common haematological malignancy. Novel therapies have led to improvement in survival. Current myeloma management is matching the progress made in improved survival through disease control while optimising quality of life with effective supportive care. Supportive treatment is an essential part of the therapeutic management of myeloma patients because it is directed towards improving the patient's quality of life and also can improve survival. The aim of this review is to highlight the relationship among life of quality, supportive care, and improvement in survival. CONFLICT OF INTEREST: None declared.

Turkish Chronic Myeloid Leukemia Study: Retrospective Sectional Analysis of CML Patients.

OBJECTIVE: here have been tremendous changes in treatment and follow-up of patients with chronic myeloid leukemia (CML) in the last decade. Especially, regular publication and updating of NCCN and ELN guidelines have provided enermous rationale and base for close monitorization of patients with CML. But, it is stil needed to have registry results retrospectively to evaluate daily CML practices. MATERIALS AND METHODS: In this article, we have evaluated 1133 patients' results with CML in terms of demographical features, disease status, response, resistance and use of second-generation TKIs. RESULTS: The response rate has been found relatively high in comparison with previously published articles, and we detected that there was a lack of appropriate and adequate molecular response assessment. CONCLUSION: We concluded that we need to improve registry systems and increase the availability of molecular response assessment to provide high-quality patient care. CONFLICT OF INTEREST: None declared.
