Abstract
OBJECTIVE Several studies quantitatively described patients with Chronic Myeloid Leukemia on active treatment with tyrosine kinase inhibitors, however there are few qualitative studies that focus their results on how to accompany patients in the course of the disease over time. The objective of this review is to find out what are the expectations, information needs and experiences that determine adherence to treatment with tyrosine kinase inhibitors in patients with Chronic Myeloid Leukemia in qualitative research articles published in the scientific literature. METHODS A systematic review of qualitative research articles published between 2003-2021 was carried out in PubMed/Medline, Web of Science and Embase databases. Main keywords used were: "Leukemia, Myeloid" and "Qualitative Research". Articles on the acute phase or blast phase were excluded. RESULTS 184 publications were located. After elimination of duplicates, 6 (3%) were included and 176 (97%) publications were excluded. Studies show that the illness is a turning point in patients' lives, and they develop their own strategies for managing the adverse effects. The factors that determine medication experiences with tyrosine kinase inhibitors should be addressed by implementing personalized strategies: this would result in early detection of problems, reinforce education at each stage and promote open discussion about complex causes underlying the treatment failure. CONCLUSIONS This systematic review provides evidence that implementation personalized strategies must be done to adress the factors that determine the illness experience with Chronic Myeloid Leukemia and receiving treatment with tyrosine kinase inhibitors.

Abstract
The BCR-ABL oncogene is a tyrosine kinase gene that is over-expressed in CML. It inhibits the TGF-β1 signaling pathway. Due to resistance of cells to the tyrosine kinase inhibitor, STI-571, the combined effect of STI-571 and TGF-β1 on K562 cells was studied in the present research. Results revealed that the TGF-β1 cell signaling pathway, which is activated in K562 cells treated with TGF-β1, activates collective cell signaling pathways involved in survival and apoptosis. It is noteworthy that treating K562 cells with STI-571 triggered apoptotic pathways, accompanied by a reduction in proteins such as Bcl-xL, Bcl-2, p-AKT, p-Stat5, p-FOXO3, and Mcl-1 and an increase in the pro-apoptotic proteins PARP cleavage, and p27, leading to an increase in sub-G1 phase-arrested and Annexin-positive cells. Interestingly, the proliferation behavior of TGF-β1-induced cells was changed with the combination therapy, and STI-571-induced apoptosis was also prompted by this combination. Thus, combination treatment appears to promote sub-G1 cell cycle arrest compared to individually treated cells. Furthermore, it strongly triggered apoptotic signaling. In conclusion, TGF-β1 did not negatively impact the effect of STI-571, based on positive annexin cells, and AKT protein phosphorylation remains effective in apoptosis.

Abstract
Chronic myeloid leukemia (CML) is a rare disease among children. A retrospective study was conducted from November 2002 to March 2019 at a single institution in China. A total of 36 pediatric CML patients (25 male and 11 female) were enrolled. Median follow-up time was 51 months (range 8-144), and 5-year overall survival and event-free survival were 95.5 ± 4.4% and 88.9 ± 6.0%, respectively. Among the 25 patients whose response to imatinib mesylate (IM) was regularly monitored, 92.0% achieved complete hematologic response at 3 months, 80.0% achieved complete cytogenetic response at 12 months, and 64.0% achieved major molecular response at 18 months after IM therapy. A higher WBC count at diagnosis was associated with failure to achieve early molecular response (EMR). Height standard deviation score after long-term treatment was significantly and positively correlated with age at diagnosis and at the start of IM therapy. Overall, IM therapy was effective in treating pediatric CML, and WBC count at diagnosis might be an ideal predictor of EMR. Moreover, retardation of height and weight growth due to IM tended to affect patients younger than 9 years old at diagnosis, and longitudinal growth might normalize further into treatment.

Abstract
Clinical trials have demonstrated that some patients with chronic myeloid leukemia (CML) treated for several years with tyrosine kinase inhibitors (TKIs) who have maintained a molecular response can successfully discontinue treatment without relapsing. Treatment free remission (TFR) can be reached by approximately 50% of patients who discontinue. Despite having similar levels of deep molecular response and an identical duration of treatment, the factors that influence the successful discontinuation of CML patients remain to be determined. In this review we will explore the factors identified to date that can help predict whether a patient will successfully achieve TFR. We will also discuss the need for the identification of predictive biomarkers associated with a high probability of achieving TFR for the future personalized identification of patients who are suitable for the discontinuation of TKI treatment.

Abstract
BACKGROUND There has been a revolution in the treatment of Chronic Myeloid Leukemia since imatinib's introduction. However, patient adherence has a great impact on the response obtained with medical treatment. This study's objective was to analyze the drug adherence and the factors that influenced it in patients with Chronic Myeloid Leukemia in a referral hospital in the Brazilian Amazon. METHOD This was a retrospective study including 120 patients with Chronic Myeloid Leukemia from January 2002 to December 2014. The adherence was estimated by the Proportion of Days Covered and the persistence by Kaplan-Meier analysis. The data was analyzed in Epi Info 7® software and the relationship between the variables was analyzed by Fisher's exact test. A p-value lower than 0.05 was considered significant. RESULTS Twenty-seven patients (22.5%) were considered non-adherent. There has been irregular medication use and disinterest in the treatment in 20.83% (n=25), of which 13 were considered non-adherent (p<0.001). A total of 26.67% (n=32) abandoned the treatment for a period. Of those, 56.25% (n=18) were non-adherent (p<0.001). Distance to the hospital, lack of medication and side-effects were all non-significant to low adherence. At the end of a 360-day follow-up, 44.16% (n=53) of patients presented a break in persistence, whose average was 255 days. CONCLUSION The adherence found in this study was similar to that found in others of its kind. The only factors that negatively influenced the adherence were disinterest and abandonment of treatment, which can reflect the need to individually educate Chronic Myeloid Leukemia patients.

Abstract
Background Chronic myeloid leukemia (CML) has a low incidence but a high burden of disease, and is treated with high-cost tyrosine kinase inhibitors (TKI). Objective To determine the time from the start of a first-line TKI until it passes to second-line, and to establish the reasons for the change of therapy time. Setting Patients with Philadelphia-positive CML treated with some TKI. Methods Retrospective cohort study, between January 1 2007 and July 31 2015, with information obtained from medical records, the time to change initial drugs to secondline therapy, and the reasons for change, were identified. Kaplan-Meier survival analysis was carried out. Main outcome measure A change in therapy to the secondline TKI and the final reason for the change of therapy. Results A total of 247 patients treated were found in 22 cities in Colombia with a mean age of 53.2 ± 15.2 years. The drug most used as initial therapy was imatinib; 53.8% of cases had to change to another TKI. 50% of patients changed therapy in 42 months, men in 24 and women in 67 months (95% CI 14.314-33.686; p = 0.001). Being male (OR 2.23; 95% CI 1.291-3.854; p = 0.004) and receiving hydroxyurea (OR 3.65; 95% CI 1.601-8.326; p = 0.002) were associated with a higher probability of switching to nilotinib or dasatinib, while receiving a new-generation TKI (OR 0.15; 95% CI 0.071-0.341; p < 0.001) reduced this risk. Conclusions A high proportion of patients needed to change to a second line with nilotinib and dasatinib management. It is necessary to obtain more real world evidence, to improve the effectiveness, adherence and safety of the treatment.

Abstract
Extramedullary leukemia (EM AML), also known as myeloid sarcoma, is a rare manifestation of acute myelogenous leukemia and often accompanies bone marrow involvement. EM AML is diagnosed based on H&E stains with ancillary studies including flow cytometry and cytogenetics. Isolated EM AML is often misdiagnosed as large cell lymphoma or other lymphoproliferative disorder. The clinical presentation is often dictated by the mass effect and the location of the tumor. The optimal treatment remains unclear. High-dose chemotherapy, radiation, surgical resection, and allogeneic stem cell transplantation are all modalities that can be incorporated into the therapy of EM AML. Cytarabine-based remission induction regimens have been the most commonly used in the upfront setting. There are limited data about the optimal consolidation. Transplantation is ideally offered for high risk disease or in the relapsed setting. In this manuscript, we will review the recent literature about EM AML, focusing on therapy and proposing a treatment algorithm for managing this rare form of leukemia. Further studies addressing risk stratification, role of molecular and genetic aberrations, and optimal treatment strategies are warranted.

Abstract
OBJECTIVE Given the multiple options for treatment of chronic-phase chronic myeloid leukemia (CML) with tyrosine kinase inhibitors, our objective was to understand treatment patterns in routine practice and prognostic indicators of response. RESEARCH DESIGN AND METHODS We conducted a retrospective medical record review of 681 patients with CML in Australia, Canada, and South Korea. Eligible patients had a diagnosis of chronic-phase CML, were Philadelphia chromosome and/or BCR-ABL positive, were aged 18 years or older, and had been treated with first-line imatinib therapy between January 2005 and September 2010. Data on patient demographics, medical history (e.g., comorbidities, Sokal score), and treatment characteristics (e.g., time to initiation, therapy duration) were abstracted. Descriptive analyses were stratified by country and therapy line. Prognostic indicators of response to imatinib were evaluated using multivariable logistic regression, adjusting for country, patient demographics, medical history, treatment characteristics, and side effects. MAIN OUTCOME MEASURES Hematologic, cytogenetic, and molecular responses at 3, 6, 12, and 18 months following initiation of each therapy line. RESULTS Patients' average age was 57 years, and 59% were male. Overall, imatinib was initiated approximately 4 months following CML diagnosis. Complete or major molecular response (C/MMR) at 6 months following imatinib initiation was 54% in Australia, 22% in Canada, and 38% in South Korea. At 18 months, over 60% of patients achieved C/MMR. Approximately 30% of patients discontinued imatinib primarily due to intolerance and lack of response. Among patients who received second-line treatment, dasatinib was used more frequently than nilotinib. Multivariable regression results indicated Sokal score was identified as a prognostic indicator of response to imatinib therapy at several time points. LIMITATIONS There are several limitations to this study. First, we selected a convenience sample of patients and physicians and therefore results may not be representative of the true population of patients with chronic-phase CML. Second, data were entered by the selected physician and could be subject to data entry errors or inaccuracies. Third, limited information was collected from the patient records, and it is possible that we did not capture additional prognostic or confounding factors related to the measured outcomes. Next, because this was an analysis of previously documented data (i.e., retrospective), we were unable to provide a priori definitions of response. Finally, multivariable analyses were limited to imatinib-related outcomes. CONCLUSIONS Treatment patterns and prognostic indicators differed by country. Health care providers, payers, and patients can utilize these results to inform treatment and policies aimed at improving the effectiveness of care for patients with chronic-phase CML.
