  • 저자들은 악성흉막삼출증을 동반한 다계열형성이상 급성골수백혈병 1예를 보고하고자 한다. 73세 남자환자가 열감과 우측흉통을 주소로 내원하여 시행한 흉막천자 흉막액의 세포진 검사에서 2개월 전에 진단받은 다계열형성 이상 급성골수백혈병 진단 당시에 골수에서 보였던 모세포가 다수 관찰되었다. 환자는 고령과 전신쇠약감으로 복합화학요법을 시행하지 않고 hydroxyurea 투여와 함께 보존적 치료만 계속해 왔다. 환자는 다계열형성이상 급성골수백혈병을 진단받은 후 4.5개월 만에 사망하였다. 급성백혈병환자에서 흉막삼출액의 존재는 흉막전이의 가능성을 높여주고 예후에 주는 영향도 완전히 배제할 수 없으므로 흉막삼출액의 악성유무를 가리는 일은 중요하리라고 생각된다.

  • 표피 포도알균은 사람 피부에 있는 정상균이나, 체내 이물질을 가진 사람이나 면역 저하자에게는 심각한 감염을 일으킬 수 있다. 13세 남자가 발열, 근육통으로 입원하였고 두피, 팔과 다리에 통증이 있는 결절성 병변이 만져졌다. 혈액검사에서 범혈구 감소증과 모세포 80% 소견을 보였고 급성 골수성 백혈병으로 진단되었다. 전신 자기공명영상 검사에서 가장자리 조영 증강을 보이는 다발 낭성 병변이, 초음파 검사에서 에코성 낭성 병변과 그 내부의 에코성 결절이 팔과 다리의 근육 내부에서 관찰되어, 낭미충증이 강력히 의심되었다. 그러나 초음파 유도하 조직 검사에서 농양이 확인되었고, 조직 배양검사에서 표피 포도알균이 동정되었다. 저자들은 백혈병 환자에서 낭미충증으로 오인되었던 표피 포도알균에 의한 전신 다발 병변이 발생한 예를 경험하였기에 보고하는 바이다.

  • 세계보건기구의 분류에 따르면 8번 염색체와 21번 염색체의 전위인 t(8;21)(q22;q22)를 가진 경우는 말초혈액이나 골수에 모세포가 20% 미만이더라도 급성골수성백혈병으로 분류하여야 하며, 이는 흔하지 않은 소견이다. 뿐만 아니라 이런 아형의 백혈병에서 골수의 저세포 충실도는 매두 드물다. 저자들은 골수세포충실도가 5% 미만으로 심하게 감소되어 있고, 골수의 모세포도 20% 미만인 환자에서 t(8;21)을 관찰하여 급성골수성백혈병으로 진단한 1례를 보고하는 바이다. 항암치료에 잘 반응하고 동종골수이식의 생착이 잘 이루어져, t(8;21)을 가진 일반적인 고세포충실성 급성골수성백혈병과 유사하게 좋은 예후를 가지는 것으로 생각된다.

  • Glutathione S-transferase (GST) enzyme levels are associated with risk of many cancers, including hematologic tumours. We here aimed to investigate the relationships between GSTM1, GSTT1 and GSTP1 polymorphisms and the risk of AML. Genotyping of GSTs was based upon duplex polymerase-chain-reactions with the confronting-two-pair primer (PCR-CTPP) method in 163 cases and 204 controls. Individuals carrying null GSTT1 genotype had a 1.64 fold risk of acute leukemia relative to a non-null genotype (P<0.05). A heavy risk was observed in those carrying combination of null genotypes of GSTM1 and GSTT1 and GSTP1 Val allele genotypes when compared with those carrying wild genotypes, with an OR (95% CI) of 3.39 (1.26-9.26) (P<0.05). These findings indicate that genetic variants of GST and especially the GSTT1 gene have a critical function in the development of AML. Our study offers important insights into the molecular etiology of AML.

  • 급성 백혈병 환자들은 병 자체로 인해 또는 치료로 인해 장기간의 호중구 감소 기간을 경험하게 되며 이로 인한 심각한 감염을 경험하게 된다. 비록 LAFR과 같은 보호된 환경의 개발로 인해 환자들이 병원의 환경과 주위 사람들의 감염으로부터 보호 받을 수 있게 되었으나 경제적 문제로 모든 급성 골수성 백혈병 환자에서 보호된 환경에서 항암치료를 시행하고 있지 못한 실정이다. 따라서 본 연구는 처음 진단되어 관해 유도 항암치료를 시행한 급성 백혈병 환자를 대상으로 보호된 환경과 일반 병실에서의 완전 관해율과 감염률 그리고 항생제 사용 비율을 비교하였다. 결과적으로 두 군 간의 완전 관해율과 호중구 감소 기간에는 차이가 없었으나 관해 유도 기간 중 현성감염률과 vancomycin, Imipenem 그리고 amphotericin-B 사용률에 있어서 유의한 차이를 보였다. 이는 급성 골수성 백혈병의 관해 유도 치료에서 보호된 환경에서 관해 유도 치료를 시행하는 것이 감염률과 이로 인한 항생제 사용률을 낮출 수 있음을 보여주고 있으며 LAFR과 같은 설비를 갖추는 것의 필요성을 나타내고 있다.

  • Translocations involving chromosome 21q22 are frequently observed in hematologic malignancies including acute myeloid leukemia (AML), most of which have been known to be involved in malignant transformation through transcriptional dysregulation of Runt-related transcription factor 1 (RUNX1) target genes. Nineteen RUNX1 translocational partner genes, at least, have been identified, but not Homeobox A (HOXA) genes so far. We report a novel translocation of RUNX1 into the HOXA gene cluster in a 57-year-old female AML patient who had been diagnosed with myelofibrosis 39 months ahead. G-banding showed 46,XX,t(7;21)(p15;q22). The involvement of RUNX1 and HOXA genes was confirmed by fluorescence in situ hybridization.

  • The discovery of the immunodeficient mice has provided a tool for establishing animal models as hosts for in vivo analysis of AML. Various model systems have been established in the last few decades, and it is essential that murine AML models are developed to exploit more specific, targeted therapeutics. In this review, we concentrate on the models of AML and discuss the development of immunodeficiency models for understanding of leukemogenesis, describe those now available and their values and document the methods used for establishing and identifying AML mice models, as well as factors influencing engraftment of human AML in immunodeficient mice. Thus, the function of this article is to provide clinicians and experimentalists with a chronological, comprehensive appraisal of all AML model systems.

  • Background: In this study, we used Daucus carota oil extract (DCOE) to target acute myeloid leukemia (AML) cells. All the AML cell lines tested were sensitive to the extract while peripheral mononuclear cells were not. Analysis of mechanism of cell death showed an increase in cells positive for annexinV and for active caspases, indicating that DCOE induces apoptotic cell death in AML. Inhibition of the MAPK pathway decreased sensitivity of AML cells to DCOE, indicating that cytotoxicity may be dependent on its activity. In conclusion, DCOE induces selective apoptosis in AML cells, possibly through a MAPK-dependent mechanism.

  • We had analyzed 10 exome sequencing data and single nucleotide polymorphism chips for blood cancer provided by the PGM21 (The National Project for Personalized Genomic Medicine) Award program. We had removed sample G06 because the pair is not correct and G10 because of possible contamination. In-house software somatic copy-number and heterozygosity alteration estimation (SCHALE) was used to detect one loss of heterozygosity region in G05. We had discovered 27 functionally important mutations. Network and pathway analyses gave us clues that NPM1, GATA2, and CEBPA were major driver genes. By comparing with previous somatic mutation profiles, we had concluded that the provided data originated from acute myeloid leukemia. Protein structure modeling showed that somatic mutations in IDH2, RASGEF1B, and MSH4 can affect protein structures.

  • Fms-like tyrosine kinase 3 (FLT3) performs a vital role in the pathogenesis of hematopoietic malignancies. Therefore in recent times, the focus of several studies was on use of FLT3 as a prognostic marker. The present study investigated the molecular characterization and incidence of FLT3 mutations in acute leukemia patients in Pakistan. A total of 55 patients were studied, of which 25 were suffering from acute lymphoblastic leukemia (ALL) and 30 were suffering from acute myeloid leukemia (AML). The polymerase chain reaction demonstrated FLT3/ITD mutations in 1 (4%) of 25 ALL patients, a male with the L2 subtype. In AML cases the rate was 4 (13.3%) of 30, three males and one female. The AML-M4 subtype was found in three and the AML M2 subtype in the other. In the AML cases, a statistically significant (p=0.009) relationship was found between WBC (109/L) and FLT3/ITD positivity. However, no significant relationship was found with other clinical parameters (p>0.05). In acute myeloid leukemia (AML) $FLT3/ITD^+$ mutation was more prevalent in elderly patients 31-40 age groups, 21-30 and 51-60 age groups respectively. In acute lymphoblastic leukemia (ALL) statistically no significant relationship was found between clinical features and FLT3/ITD positivity (p>0.05). However, in acute lymphoblastic leukemia (ALL) $FLT3/ITD^+$ mutation was more commonly found in age groups of 21-30.
