Hematologic malignancy of the breast is very rare. Here, we report a case of relapsed acute myeloid leukemia (AML) presenting as multiple breast masses. A 77-year-old female visited an outpatient clinic reporting palpable masses in both breasts. She had a medical history of AML, which showed complete remission after nine cycles of chemotherapy. On mammography and ultrasonography, there were multiple masses correlated with her palpable symptoms accompanied by enlarged lymph nodes. Core needle biopsy immunohistochemistry (IHC) results indicated AML and blastic plasmacytoid dendritic cell neoplasm. AML was confirmed using bone marrow biopsy. Although very rare, when a patient with a history of hematologic malignancy presents a palpable mass in the breast, clinicians should conduct proper tissue analysis, including IHC stating for leukemic markers, to guide appropriate diagnosis and treatment.

Purpose : In this study, we retrospectively analyzed the clinical outcomes of patients who underwent allogeneic hematopoietic stem cell transplantation (HSCT) grafted from HLA-matched parents. Methods : Seven children with acute leukemia (4 acute lymphoblastic leukemia, 3 acute myeloid leukemia) in first complete remission received allogeneic HSCT from their respective parents at the St. Marys Hospital between April, 1999 and October, 2005. The median age of patients at transplantation was 5 years (range, 1-11 years; 2 male, 5 female) and the median age of donors was 35 years (range, 30-41 years; 5 male, 2 female). We investigated the clinical outcomes such as engraftment, acute and chronic graft-versus-host disease (GVHD), transplant-related morbidity and mortality, relapse and survival. Results : Median time from transplantation to last follow-up was 69.5 months (range, 18.8-96.5 months). All patients were successfully engrafted, with a median time of 11 days (range, 10-16 days) and 26 days (range, 13-39 days) for neutrophil and platelet recovery, respectively. Grade II acute GVHD occurred in 3, and grade III acute GVHD in 1 of 7 recipients. Extensive chronic GVHD developed in 2, and limited chronic GVHD in 1 of 7 recipients. Death from transplant-related complications occurred in 1, and relapse occurred in 1 of 7 recipients. Estimated 5-year overall survival was $83{\pm}15%$. Conclusion : The clinical outcomes of recipients who underwent HSCT from HLA-matched parents were comparable to those of patients who received HSCT grafted from HLA-matched sibling donors in childhood leukemia. HLA typing of parents, as well as siblings will increase the likelihood of finding an HLA-matched family donor for patients who need HSCT.

Purpose : p16 gene, mapped to the 9p21 chromosomal region, has emerged as a candidate tumor suppressor gene in human neoplasm. It is an inhibitor of cyclin-dependent kinase and inhibits Rb phosphorylation. In a variety of tumors including childhood acute lymphoblastic leukemia (ALL), deletion and/or mutation of the p16 gene has been found. Despite their high frequency, the prognostic importance of p16 alterations is still controversial in ALL and has been reported to be either unfavorable or similar to that of other patients. We studied the correlation between loss of p16 protein confirmed by immunohistochemical staining and clinical outcomes of patients diagnosed as ALL. Methods : We performed an immunohistochemical staining for p16 protein in 74 cases of bone marrow biopsy slide initially diagnosed as ALL between January 1998 and December 2006. We reviewed the clinical manifestations, laboratory findings, treatment outcomes retrospectively. Results : Of 74 slides, 12 were negative for p16 protein. Seven were males and 5 were females with a median age at diagnosis was 5.8 (1.3-18.8) years. Initial WBC were 17,225 $(500-403,300)/{\mu}L$. By immunologic surface marker analysis, 7 patients were early pre-B CALLA (+) and 5 patients were T-cell ALL. Two patients of intermediate risk group had relapsed and died. Three patients had family history of breast cancer. Four patients died and overall survival rates were $53.5{\pm}18.7%$. Conclusion : Loss of p16 protein is supposed to be an independent risk factor of childhood ALL associated with poor outcomes. In clinical setting, the clinician must take into account p16 status, not only at the genomic but also at the protein level. Further clinical experience on thoroughly investigated cases will help a better understanding between p16 status and clinical outcomes.

Background and purpose : Patients with acute leukemia experience prolonged periods of neutropenia due to their disease or its treatment. For this reason, they often develop serious infectious complications. Although antibiotic therapy has improved in recent years, the fatality rate from infection remains high. For the control of infection, protected environment was developed. But because of economic issue, most of chemotherapy with acute myeloid leukemia have conducted in non-protected environment. So this study compared the rate of complete remission, days with neutropenia, rate of fever, rate of positive culture, rate of overt infection and use of antibacterial and antifungal agents with patients within non-protected environment and protected environment, retrospectively, Patients with acute myeloid leukemia during first remission induction chemotherapy were eligible for this study, Methods : Retrospective analysis was conducted between patients in non-protected (25 patients) and protected environment (14 patients) with acute myeloid leukemia during remission induction chemotherapy Results : Rate of overt infection, rate of fever, rate of positive culture and rate of use of antibiotics were significantly high in patients within non-protected environment compared with patients within protected environment. There were no differences in rate of complete remission and days of neutropenia Conclusions : This study suggests protected environment for patients with acute myeloid leukemia during remission induction chemotherapy could reduce rate of overt infection, and rate of use of antibiotics.

Objective : The purpose of this study is to demonstrate the therapeutic effect of oriental treatment on Acute Myelogenous Leukemia. Methods : The patient was treated by Acupuncture, Indirect Moxibustion, Herb Medicine (Seogakjihwangtang-gamibang), and had significant improvement in the Acute Myelogenous Leukemia. Results : 1. Acute Leukemia is one of the most common malignant neoplasm of pediatrics, and is chracterised by anemia, infections, bleeding, debility, paleness, fever, anorexia, lymphoadenia, hepatomegaly, splenomegaly, etc. 2. The management of Acute Myelogenous Leukemia consists of the challenge of optimizing chance for prolonged remission and cure, while minimizing the toxicity to the patients. Therefore oriental medical treatment may be useful for this. 3. We experienced a case of the 10-year-old male patient with Acute Myelogenous Leukemia, after oriental medical treatment his chief symptoms(anemia, bleeding, purpura, debility, paleness, fever, anorexia, insomnia, etc)and general condition were improved. Conclusion : A 10-year-old male patient with Acute Myelogenous Leukemia, after oriental medical treatment his chief symptoms and general condition were improved. This oriental medical treatment may be possible or effective in Acute Myelogenous Leukemia. The more clinical study about oriental medical treatment on Acute Myelogenous Leukemia will be needed.

We studied the expression of the cell surface antigen associated with myeloid and lymphoid leukemias on bone marrow or peripheral blood blast cells from 153 leukemic patients including 61 cases of acute myelogenous leukemias(AML), 46 of acute lymphocytic leukemias(ALL) and 12 of acute leukemias. They were analyzed by direct or indirect immunofluorescence method for reactivity with the monoclonal antibodies to B cells(CD10, CD19, SmIg), T cells(CD2, CD5, CD7, CD3, CD4, CD8), myeloid antigen(CD13, CD14, CD33, CD61) and a nonspecific antigen, HLA-DR. Lymphoid associated markers detected on AML is CD7 32.8%, CD10 14.8%, CD5 13.1%, CD2 6.6% and CD19 1.6%. TdT was positive in 4.9% of AMLs. Hybrid leukemias were 8 cases out 61 AML cases and were mainly composed of monocytic lineage, M4 and M5a. Myeloid markers detected in ALL were CD13 2.2% and CD33 2.2%. In this study, immunologically classified ALLs were composed of 65.2% of CALLA (+) B precursor type, 10.9% of CALLA (-) B precursor pattern, 8.7% of T cell type, 2.2% of B cell type, 4.5% of mixed lymphoid lineage(B&T), 2.2% of undifferentiated leukemia, and 6.5% of hybrid leukemia. Twelve cases of acute leukemias ware finally diagnosed to be 5 cases of hybrid leukemia, 3 cases of B lineage, 3 case of T lineage and 1 case of mixed lymphoid(B&T) leukemia. In summary, we think the best method for typing acute leukemias is by using a combination of FAB classification and immunophenotying.

Purpose : In 1970, the Berlin-Frankfurt-Munster(BFM) group introduced an intensification therapy after remission induction to reduce relapse of acute lymphoblastic leukemia(ALL) in childhood. Delayed intensification(DI) phase has been included for treatment of ALL in our hospital since the mid-1990s. The purpose of this study is to evaluate the outcome with vs. without DI phase and the outcome with two vs. one DI phase for intermediate risk patients. Methods : One hundred and thirty nine children with ALL who were treated at the Department of Pediatrics of Wonju Christian Hospital and Yonsei University Medical Center between March, 1990 and July, 2002 were analysed retrospectively. Results : Thirty-eight patients were treated with a DI phase, and 101 patients were treated without a DI phase. Among the DI patients, seven patients were treated with a double DI phase. Five-year overall survival(OS) in the low, intermediate, and high risk groups were 68%, 66% and 58%, respectively. 5-year OS in DDI, DI, and control were 95%, 86% and 40%, respectively. In the low risk group, 5-year event free survival(EFS) in DI, and control were 94% and 58%, respectively. Conclusion : Delayed intensification improved EFS on childhood ALL in all risk groups.

The present sturdy was designed to determine the effect of the antiproliferation in human cancer cells using the ordinary vegetable soup (VS), the soup with broccoli (VSB) and the soup with tomatoes(VST). Human cancer cells identify the cancer cell growth with MTS, using stomach cancer cell line(AGS), human promyelocytic leukemia (HL-60) and lung cancer cell line (A549). VSB and VST are effective on the cancer cell growth inhibition activities of AGS and have a significance compared with VS. VST has a significance with HL-60 and VSB works well in A549 more than VS. Mixed vegetable soup is considered to applicate with functional materials and using for wellness life.
