A CD7 positive acute leukemia, lacking CD4, CD8, CD3, CD13 and CD33 expression may include 4 categories; acute T-cell leukemia, mixed lineage leukemia, acute undifferentiated leukemia and CD7 positive acute myeloid leukemia. Therefore, the expression of cyCD3 or the presence of TCR gene rearrangement can make the diagnosis of acute T-cell leukemia. We report a patient with acute T-cell lymphoblastic leukemia, showing CD7+, CD4-CD8-, and CD3-expression and TCR gamma gene rearrangement.

Graft-versus-host disease can develop in immunosuppressed individuals who receive blood product transfusions that contain imrnunocompetent lymphocytes. We report a case of transfusion-associated graft-versus-host disease(TA-GVHD) that developed in a patient with acute lymphocytic leukemia who were undergoing therapy. The groups at risk for development of TA-GVHD, the clinical presentation and course, and methods of diagnosis are summarized. Prevention of TA-CVHD is possible by irradiation of blood products given to patients at risk, but problems remain in determining the groups that warrant such measures. We should be aware of the risk of developing TA-GVHD after routine blood transfusion, especially in areas where the population's HLA types are rather homogeneous.

PURPOSE: Childhood leukemia is a serious trauma affecting both adolescents and their parents, who experience painful process. However, adolescents with leukemia and their parents also experience positive changes, which is referred to as posttraumatic growth. We examined posttraumatic growth, core beliefs, impact of event, and event-related rumination in adolescents within 5 years of a diagnosis of childhood leukemia and their parents. METHODS: The participants were 68 adolescents with childhood leukemia (aged 13~18 years) and their parents, who were recruited from C university hospital in Korea from May to September 2016. The Posttraumatic Growth Inventory, Core Belief Inventory, Impact of Event Scale-Revised, and Event-related Rumination Inventory were completed by the adolescents and their parents. The mean scores and correlations between variables were investigated for both set of participants. RESULTS: Parents showed significantly higher levels of posttraumatic growth, disruption of core beliefs, impact of event, and invasive rumination than adolescents. Disruption of core beliefs and deliberate rumination were positively correlated with posttraumatic growth in both groups. CONCLUSION: Nursing intervention programs that involve modifying core beliefs and inducing a positive thought can help adolescents with leukemia and their parents grow after traumatic events.

OBJECTIVETo set up the technical system of multiplex fluorescence in situ hybridization M-FISH and to explore its application in detection of the complex chromosome abnormalities in leukemia.

METHODSThe complex chromosome abnormalities of two leukemia patients were analyzed by the combination use of classical cytogenetics, chromosome painting (CP), FISH and M-FISH.

RESULTSIn a case of acute lymphoblastic leukemia-L2, the complex karyotype: 46,XY,der(2)t(2;9),der(9)t(9;12;22) was identified by M-FISH, which was detected as 46,XY,der(9)t(9;12) by classical cytogenetics; In a case of acute monocytic leukemia-M5, the complex chromosome abnormalities: 46,XY,der(2)t(2;17), der(10)t(10;11;17), der(11)t(11;?) was revealed by M-FISH, which was confirmed by CP and FISH, and mixed lineage leukemia (MLL) gene was also found involved in this complex chromosome translocation.

CONCLUSIONM-FISH was proved to be a powerful tool to examine the complicated karyotypes and hopefully to elucidate nearly all chromosomal aberrations in leukemia and other cancers.

In recent years, standardized treatment based on the risk stratification has been applied to clinical diagnosis and treatment of leukemia, which significantly improves the remission rate of ALL. However, relapse after remission remains an important challenge for long term efficacy. Chromosomal karyotype analysis is often used clinically to study the genetic features of ALL. As leukemia-specific markers, the cytogenetic and molecular genetic abnormalities can be used to evaluate prognosis and make an effective and optimal therapy. Furthermore, they are also used to track minimal residual disease. Therefore, the cytogenetic and molecular genetic abnormalities may become a monitor and a new target for the treatment of leukemia. This review briefly introduces the structure and physiological function of B-ALL associated cytogenetic and molecular genetic abnormalities, focusing on their prognostic effect on B-ALL.
