<p>Chronic myelogenous leukemia (CML) is a type of cancer caused by a disturbance in the hematopoietic stem cells. CML itself rarely occur on women who are in labor and an advanced procedure in this event has become a special challenge for medics, especially an anesthesiologist. This limits the development of standard anesthesia guidelines, so in this case we describe the incidence of CML in pregnancies performed by Cesarean section with general anesthesia.</p><p>The first pregnant patient was 36 weeks pregnant; the patient was first diagnosed with Chronic myelogenous leukemia (CML) at the age of 26-28 weeks, at that time the patient complained of frequent dizziness, abdominal pain and weakness, then the patient complained of bleeding gums, and currently the patient complained of nosebleeds. The Bone Marrow shows Conclusion an accelerated phase chronic myeloid leukemia (CML) (suspected atypical CML) with nutritional deficiency. We perform General Anesthesia technique Rapid Sequence Intubation with Regimen Fentanyl 100 mcg, Propofol 80 mg and Rocuronium 50 mg.</p><p>The patient was admitted to the ICU for 2 days before transferring to intensive care and the patient received intravenous paracetamol 1 gram four times, cefazolin 1 gram twice a day, lansoprazole 30 mg once a day, tranexamic acid 1gr three times a day, and 15 mcg per hour fentanyl contionously. Hemodynamic patients in the ICU are in a stable condition. On the second postoperative day of care, the patient was transferred to the High care ward, then at the third postoperative day the patient's hemodynamics was stable and the patient was transferred to a normal room.</p>

G1 Cell Cycle Arrest

Chronic myeloid leukemia (CML) is a malignant tumor caused by the abnormal proliferation of hematopoietic stem cells. Among a new series of acridone derivatives previously synthesized, it was found that the methoxybenzyl 5-nitroacridone derivative 8q has nanomolar cytotoxicity in vitro against human chronic myelogenous leukemia K562 cells. In order to further explore the possible anti-leukemia mechanism of action of 8q on K562 cells, a metabolomics and molecular biology study was introduced. It was thus found that most of the metabolic pathways of the G1 phase of K562 cells were affected after 8q treatment. In addition, a concentration-dependent accumulation of cells in the G1 phase was observed by cell cycle analysis. Western blot analysis showed that 8q significantly down-regulated the phosphorylation level of retinoblastoma-associated protein (Rb) in a concentration-dependent manner, upon 48 h treatment. In addition, 8q induced K562 cells apoptosis, through both mitochondria-mediated and exogenous apoptotic pathways. Taken together, these results indicate that 8q effectively triggers G1 cell cycle arrest and induces cell apoptosis in K562 cells, by inhibiting the CDK4/6-mediated phosphorylation of Rb. Furthermore, the possible binding interactions between 8q and CDK4/6 protein were clarified by homology modeling and molecular docking. In order to verify the inhibitory activity of 8q against other chronic myeloid leukemia cells, KCL-22 cells and K562 adriamycin-resistant cells (K562/ADR) were selected for the MTT assay. It is worth noting that 8q showed significant anti-proliferative activity against these cell lines after 48 h/72 h treatment. Therefore, this study provides new mechanistic information and guidance for the development of new acridones for application in the treatment of CML.

Objective To discuss the new dasatinib dosing regimen for the treatment of chronic phase chronic myelogenous leukemia (CP CML) in patients who failed or were intolerant to imatinib therapy. Data Sources Literature published between July 2008 and December 2008 was accessed via MEDLINE, the Proceedings of the American Society of Hematology, and the Proceedings of the American Society of Clinical Oncology using the key words chronic myelogenous leukemia, chronic myeloid leukemia, dasatinib, imatinib, nilotinib, pharmacokinetics, and regimen. Study Selection And Data Extraction Meeting abstracts and reports of major Phase 1–3 studies published in English are included. Data Synthesis Imatinib is the standard first-line therapy for CML; however, some patients develop resistance or are intolerant to the drug. Dasatinib was approved for the treatment of imatinib-resistant/intolerant patients with CML or Philadelphia chromosome–positive acute lymphoblastic leukemia at the dosage of 70 mg twice daily. A Phase 3 dose-optimization study was performed to compare this regimen with others, including dasatinib 100 mg once daily, in patients with CP CML. Results of this study showed that there was no significant difference in efficacy between these 2 regimens. The safety profile was improved in the 100-mg once-daily dasatinib arm with significantly reduced frequencies of grade 3–4 thrombocytopenia and all-grade pleural effusions. The number of patients who had to discontinue, reduce, or interrupt their dosage was also less among patients taking dasatinib 100 mg once daily. Conclusions Dasatinib 100 mg once daily has a more favorable risk to benefit assessment compared with the previous 70 mg twice-daily regimen and is now the recommended schedule for patients with CP CML.

AbstractChronic myelogenous leukemia (LML) was recognized as a distinct entity in the mid-1800s. Since Nowell and Hunagerford initiated their research on CML in1960 our understanding in CML has been increasing. Imatinib became the preferred treatment from 2000 onwards as a result of its unprecedented success. The lack of structured Indian data on CML led to the formation of a CML data cansortuim which invited CML data albiet retro spartive form around the country including major cancer service providers both government and private. We provide a summary of published Indian data on CML here.

Abstract The hallmarks of chronic myelogenous leukemia (CML) include the Philadelphia chromosome (Ph) translocation [t (9;22)(q34;q11)] and consistent molecular genetic aberrations: a break within a restricted 5.8 kb DNA segment, bcr, on chromosome 22q11; transposition of the c- abl protooncogene from chromosome 9q34 to 22q11; and formation of a hybrid bar-abl gene encoding an abnormal 210 Kd bcr-abl protein with augmented tyrosine kinase enzymatic activity. These molecular phenomena may occur even in the absence of cytogenetic evidence of the Ph translocation. They are highly specific and sensitive markers for CML, and are presumed to play a significant role in the pathogenesis of this malignancy. Surprisingly, we have encountered 11 patients who lacked the Ph translocation, bcr rearrangement, and (in the four patients with available mRNA) a bcr-abl message, and yet had a disease phenotype at diagnosis that was a morphologic facsimile of classic chronic phase CML. These patients presented with high white blood cell counts, neutrophilia, occasional basophilia, splenomegaly, and a hypercellular bone marrow with granulocytic hyperplasia and a left shift in myeloid maturation. Despite the striking resemblance between the early stages of bcr-negative and bcr-positive CML, disease progression manifests distinctly in these two disorders. In contrast to the blastic transformation that inevitably complicates bcr-positive CML, the natural history of our 11 Ph-negative, bcr-negative CML patients was characterized by increasing leukemia burden with leukocytosis, pronounced organomegaly, extramedullary infiltrates, and eventual bone marrow failure (anemia and thrombocytopenia) without marked increases in blast cells. Our current observations suggest that a chronic myeloid leukemia process can develop without associated changes in the bcr or c- abl genes. Although the initial phase of this disease is indistinguishable from CML, the presence or absence of molecular markers may aid in the prediction of the clinical course of Ph-negative CML.

<b><i>Background:</i></b> Autoimmune hemolytic anemia (AIHA) might be associated with underlying hematological malignancies such as chronic lymphocytic leukemia. However, the association between AIHA and chronic myelogenous leukemia is extremely unusual. <b><i>Summary:</i></b> We reviewed case reports and series of 54 patients with chronic myeloid leukemia (CML) who developed autoimmune hemolysis between 1952 and 2018. Almost all the patients were in the chronic phase and were classified into transplant and non-transplant groups. The onset of autoimmune hemolysis was earlier in the transplant group and required second- and third-line therapy to control it. The etiology of hemolysis is poorly understood but attributed in the transplant group to immune reconstitution, viral infections, or CML relapse. On the other hand, it is thought to be related in the non-transplant group to CML medications, especially interferon. <b><i>Key Messages:</i></b> Although AIHA is uncommon in chronic myelogenous leukemia patients, it should be in the differential diagnosis list for those who develop a sudden drop in hemoglobin without a bleeding source.

Cyclic leukocytosis has been previously described in patients with chronic myeloid leukemia (CML). The purpose of this report is to call attention to the possibility of a specific long-term cycle of approximately two months in CML, on the basis of the reported patients studied prospectively with no treatment and to describe an additional case with similar changes. Kinetic studies suggest that the leucocyte oscillation observed would reflect variation in cell production. Implications of the findings with regard to pathogenesis and therapy of the disease are discussed. A long-term cycle of the neutrophil count, showing a period of approximately two months, was also found in eight children with acute myelogenous leukemia (AML) in remission, analyzed retrospectively.

Abstrak: Leukemia mieloid kronis (chronic myeloid leukemia/CML) adalah penyakit klonal dari sel induk hematopoietik, secara sitogenetik ditandai dengan adanya kromosom Philadelphia (t[9,22][q34;q11]), yang merupakan fusi BCR-ABL1 onkogen. Nilotinib, generasi kedua inhibitor kinase tirosin, merupakan turunan aminopirimidin yang menghambat aktivitas kinase tirosin protein BCR-ABL. Dengan aktivitas penghambatan yang 10-60 kali lebih besar daripada imatinib, pada terapi lini pertama standar untuk CML, nilotinib efektif untuk CML fase kronik dan akselerasi yang resisten terhadap imatinib, namun terapi kombinasi nilotinib dengan agen lainnya masih diperlukan untuk pasien dengan CML krisis blas. Nilotinib aktif terhadap beberapa mutan BCR-ABL yang resisten terhadap imatinib, kecuali mutan T315I. Mutasi spesifik E255K/V, Y253H/F, F359C/V, dan L248V umumnya kurang sensitif terhadap nilotinib. Sebagai terapi lini pertama pada pasien CML fase kronik dengan Ph+ yang baru terdiagnosis, nilotinib menunjukkan CCyR dan MMR yang lebih tinggi serta pengembangan menjadi fase akselerasi/krisis blas serta resiko kematian yang lebih rendah, bila dibandingkan dengan imatinib. Simpulan penelitian ini ialah nilotinib lebih unggul dibandingkan dengan imatinib sebagai terapi lini pertama pada pasien CML fase kronik dengan Ph+ yang baru terdiagnosis,Kata kunci: chronic myeloid leukemia (CML), nilotinib, imatinib, terapi lini pertama  Abstract: Chronic myeloid leukemia (CML) is a clonal disease of the hematopoietic stem cells, cytogenetically characterized by Philadelphia chromosome (t[9,22][q34;q11]) leading to the fusion of BCR-ABL1 oncogene. Nilotinib, the second-generation tyrosine kinase inhibitor (TKI), is an aminopyrimidine derivative that inhibits the tyrosine kinase activity of the chimeric protein BCR-ABL. Its inhibitory activity is 10-60 times that of imatinib, therefore, as the standard first-line therapy for CML, nilotinib is effective in the case of CML-CP and CML-AP with imatinib resistant or intolerant. Albeit, novel approaches with nilotinib-based combinations are required for patients in CML-BP. Nilotinib is active against several imatinib-resistant BCR-ABL mutants with the exception of T315I. Specific mutations that are less sensitive to nilotinib include E255K/V, Y253H/F, F359C/V, and L248V. As the first-line therapy of patients with newly diagnosed Ph+ CML-CP, nilotinib has higher rates of CCyR and MMR, lower rates of progression to AP or BC, and lower risk of CML related death when compared with imatinib. In conclusion, nilotinib is superior to imatinib as the the first-line therapeutic option in newly diagnosed Ph+ CML-CP patients.Keywords: chronic myeloid leukemia (CML), nilotinib, imatinib, first line therapy
