BACKGROUND: Allogeneic bone marrow transplantation across ABO incompatibility barriers may result in immune mediated hemolysis. Hemolysis may be avoided by RBC depletion from the graft. In vitro graft manipulations carry the risk of hematopoietic stem cell loss, a factor that may be most important in graft failure. We report 16 major ABO blood group incompatible allogeneic bone marrow transplants using erythrocyte depletion of marrow prior to infusion. METHODS: From March 1997 to July 2001 in Yonsei University College of Medicine, 16 patients underwent ABO blood group incompatible allogeneic BMT: 5 for acute myelocytic leukemia, 5 for severe aplastic anemia, 3 for acute lymphocytic leukemia, 2 for chronic myelocytic leukemia, and 1 for myelodysplastic syndrome. RBC depletions were done with automatic cell separator, COBE Spectra (COBEBCT Inc., Lakewood, USA). RBC removal rates and mononuclear cell recovery rates were calculated. And the evidence of successful engraftment and intravascular hemolysis were also evaluated. RESULTS: The RBC removal rate was 99.1+/-0.0% and a mean of 1% of the original red cell volume was contained in the final infusate. The mononuclear cell recovery rate was 70.0+/-16.3% from the original MNCs. Fourteen patients tolerated the infusion of the marrow concentrates without any adverse effects. Two patients experienced hemoglobinuria, but disappeared within 2 days by continued observation. After transplantation, absolute neutrophil counts exceeded 500/nL by 10.8+/-1.9 days, platelet counts exceeded 50,000/nL by 30.5+/-8.5 days, and reticulocytosis sustained at >1% was by 25.8+/-13.9 days. CONCLUSION: RBC depletion from ABO major mismatched bone marrow aspirates by the automatic cell separator is a safe and effective technique.

PURPOSE: Pulmonary toxicities, including infectious pneumonia (IP) and idiopathic pneumonia syndrome (IPS), are serious side effects of total body irradiation (TBI) used for myeloablative conditioning. This study aimed to evaluate clinical factors associated with IP and IPS following TBI. MATERIALS AND METHODS: Fifty-eight patients with hematologic malignancies who underwent TBI before allogeneic hematopoietic stem cell transplantation between 2005 and 2014 were reviewed. Most patients (91%) received 12 Gy in 1.5 Gy fractions twice a day. Pulmonary toxicities were diagnosed based on either radiographic evidence or reduced pulmonary function, and were subdivided into IP and IPS based on the presence or absence of concurrent infection. RESULTS: Pulmonary toxicities developed in 36 patients (62%); 16 (28%) had IP and 20 (34%) had IPS. IP was significantly associated with increased treatment-related mortality (p = 0.028) and decreased survival (p = 0.039). Multivariate analysis revealed that the risk of developing IPS was significantly higher in patients who received stem cells from a matched unrelated donor than from a matched sibling donor (p = 0.021; hazard ratio [HR] = 12.67; 95% confidence interval [CI], 1.46–110.30). Combining other conditioning agents with cyclophosphamide produced a higher tendency to develop IP (p = 0.064; HR = 6.19; 95% CI, 0.90–42.56). CONCLUSION: IP and IPS involve different risk factors and distinct pathogeneses that should be considered when planning treatments before and after TBI.

The efficacy of tandem high-dose chemotherapy and autologous stem cell rescue (HDCT/ASCR) was investigated in patients with high-risk neuroblastoma. Patients over 1 yr of age who were newly diagnosed with stage 4 neuroblastoma from January 2000 to December 2005 were enrolled in The Korean Society of Pediatric Hematology-Oncology registry. All patients who were assigned to receive HDCT/ASCR at diagnosis were retrospectively analyzed to investigate the efficacy of single or tandem HDCT/ASCR. Seventy and 71 patients were assigned to receive single or tandem HDCT/ASCR at diagnosis. Fifty-seven and 59 patients in the single or tandem HDCT group underwent single or tandem HDCT/ASCR as scheduled. Twenty-four and 38 patients in the single or tandem HDCT group remained event free with a median follow-up of 56 (24-88) months. When the survival rate was analyzed according to intent-to-treat at diagnosis, the probability of the 5-yr event-free survival+/-95% confidence intervals was higher in the tandem HDCT group than in the single HDCT group (51.2+/-12.4% vs. 31.3+/-11.5%, P=0.030). The results of the present study demonstrate that the tandem HDCT/ASCR strategy is significantly better than the single HDCT/ASCR strategy for improved survival in the treatment of high-risk neuroblastoma patients.

PURPOSE: Of the cancers in childhood, leukemia is the most frequent one. For the desirable control of childhood leukemia, the basic data for the incidence has a great importance. The authors made a report about the incidence of leukemia in childhood, which analyzed the data from 126 cases in Kyongnam province, Korea, during 1991~1995. METHODS: The data were obtained from 126 new cases of childhood leukemia who had been living in the Kyongnam province and were diagnosed at the 26 university hospitals or general hospitals in the Kyongnam area and other cities from 1991 to 1995. RESULTS: The age-and-sex adjusted annual incidence rate per 100,000 population during 1991~1995 varied from 1.82 to 2.86, and cumulative annual incidence rate was 2.41 (male 2.26 and female 2.57 respectively). Male to female sex ratio was 1:1 in total cases. By the major types of childhood leukemia, the cases were composed of acute lymphocytic leukemia 70.6%, acute myelocytic leukemia 26.9% and chronic myelocytic leukemia 2.5%. The cumulative annual incidence rate per 100,000 population (crude rate) during 1991~1995 were 2.77 in Ulsan city, 2.62 in Chinju city and 2.34 in the whole area of Kyongnam province. CONCLUSION: It was concluded that the age-and-sex adjusted annual incidence rate per 100,000 of childhood in Kyongnam province was 2.41, which was lower than that in Pusan city in the same period. And, there was no significant difference of the cumulative annual incidence rate between Ulsan area and Chinju area in the same period.

Autologous stem cell transplantation (ASCT) for the treatment of high-risk neuroblastoma (NBL) is an accepted method for restoring bone marrow depression after high dose chemotherapy. We retrospectively analyzed eighty eight cases of NBL that underwent ASCT following marrow ablative therapy at 12 transplant centers of the Korean Society of Pediatric Hematology-Oncology between January 1996 and September 2000. Seventy nine children were of stage IV NBL and 9 were of stage III with N-myc amplification. Various cytoreductive regimens were used. However, the main regimen was 'CEM' consisting of carboplatin, etoposide and melphalan, and this was used in 66 patients. Total body irradiation was also added in 36 patients for myeloablation. To reduce tumor cell contamination, stem cell infusions after CD34+ cell selection were performed in 16 patients. Post-transplantation therapies included the second transplantation in 18 patients, interleukin2 therapy in 45, 13-cis retinoic acid in 40, 131-meta-iodobenzylguanidine in 4, conventional chemotherapy in 11, and local radiotherapy in 8. Twenty two patients died, sixty six patients are surviving 1 to 46 months after ASCT (median followup duration, 14.5 months). Although the follow-up period was short and the number of patients small, we believe that ASCT might improve the survival rate in high-risk NBL.

PURPOSE: Children with Malignant lymphoma who is in the advanced stage at diagnosis or relapses during treatment have a poor prognosis. Recently, hematopoietic stem cell transplantation (HSCT) for advanced stage or refractory/relapsed lymphoma performed frequently. However, the role for HSCT for children with malignant lymphoma is still controversial. In this study, we reviewed children with malignant lymphoma who received HSCT and analyzed the results. METHODS: Questionnaires were made and sent to a group of teaching hospitals, with a return of 37 questionnaires from 11 hospitals. 33 patients with Non-Hodgkin lymphoma (NHL) and 4 patients with Hodgkin disease (HD) who received HSCT from 1997 to 2004 in Korea were enrolled in this study. Disease state at diagnosis, relapses during treatment, disease state at HSCT, and survival record were analyzed. All Data were reviewed with the questionnaires from the 11 teaching hospitals. RESULTS: Four patients with HD received HSCT at the 2nd complete remission after relapse. Survival rate for HD was 100% and their follow up duration ranged from 0.2 to 6.2 years (median 2.4 years). The 2-year survival rate for NHL was 68.1+/-9.0% and their follow up duration ranged from 0.1 to 7.6 years (median 1.5 years). The 2-year survival rate in patients with advanced stage at diagnosis and in relapsed/refractory patients were 83.6+/-1.1% and 55.9+/-12.9%, respectively (P=0.12). The mortality asssociated with HSCT was only 1 case, and most of the transplantation related complications did not resulted in death. CONCLUSION: Our results suggest that high dose chemotherapy followed by HSCT in children with malignant lymphoma is a safe procedure, which at the same time improves the results of standard treatment.

Purpose:
Acute promyelocytic leukemia (APL) is a rare disease in children and there are some different characteristics between children and adult. We aimed to evaluate incidence, clinical characteristics and treatment outcomes of pediatric APL in Korea.
Materials and Methods:
Seventy-nine pediatric APL patients diagnosed from January 2009 to December 2016 in 16 tertiary medical centers in Korea were reviewed retrospectively.
Results:
Of 801 acute myeloid leukemia children, 79 (9.9%) were diagnosed with APL. The median age at diagnosis was 10.6 years (range, 1.3 to 18.0). Male and female ratio was 1:0.93. Thirty patients (38.0%) had white blood cell (WBC) count greater than 10×109/L at diagnosis. All patients received induction therapy consisting of all-trans retinoic acid and chemotherapy. Five patients (6.6%) died during induction chemotherapy and 66 patients (86.8%) achieved complete remission (CR) after induction chemotherapy. The causes of death were three intracranial hemorrhage, one cerebral infarction, and one sepsis. Five patients (7.1%) suffered a relapse during or after maintenance chemotherapy. The estimated 4-year event-free survival and overall survival (OS) rates were 82.1%±4.4%, 89.7%±5.1%, respectively. The 4-year OS was significantly higher in patients with initial WBC < 10×109/L than in those with initial WBC ≥ 10×109/L (p=0.020).
Conclusion
This study showed that the CR rates and survival outcomes in Korean pediatric APL patients were relatively good. The initial WBC count was the most important prognostic factor and most causes of death were related to serious bleeding in the early stage of treatment.

BACKGROUND: Hematopoietic stem cell transplantation (HSCT) is one of the most important armamentarium against various hematologic malignancies or some solid tumors. We investigated the number of patients who might need transplants and compared with that of actual transplants to conceptualize current status and circumstances of HSCTs in Korean children. METHODS: Questionnaires were sent to Korean Society of Hematopoietic Stem Cell Transplantation (KSHSCT) members who were taking care of children with malignancies or hematologic diseases. Almost all of the newly diagnosed patients between Jan, 1st and Dec, 31st, 2003 were enrolled in the study. RESULTS: Seven hundred forty eight children (male to female ratio = 1.4:1) were enrolled. The median age was 6.1 years old (8 days~28.8 years old). Malignant diseases consisted of 695 cases (92.9%), and among them almost half were hematologic malignancies. The participating members speculated that HSCTs should be indicated in 285 children (38.1%) which included 209 allogeneic, and 76 autologous transplants. In reality, however, allogeneic HSCTs were performed only in 140 children (67.0%) with the median interval of 5.9 month, and autologous transplants in 44 children (57.9%) with 8.3 month. In autologous setting, all the patients received peripheral blood stem cells (PBSCs), whereas bone marrow (61%), cord blood (34%), and PBSC (5%) were used in allogeneic HSCTs. Donor types were as follows: unrelated donor (37%), cord blood (34%), sibling donor (25%), and family (4%). The reasons for not performing HSCTs were unfavorable disease status or death, no availability of suitable donor, economical situation, and refusal by parental preferences. Under the strict insurance regulations, many transplants were not covered by insurance. More autologous transplants were performed without insurance coverage than allogeneic HSCTs (P=0.013). Those cases were advanced cases and HLA mismatch transplants for allogeneic setting, and relatively rare diseases still awaiting favorable results of transplants for autologous setting. CONCLUSION: HSCTs are essential part of treatment strategies for children with various diseases. Unfortunately, however, a third of patients who were in need of transplants did not receive HSCTs due to various reasons. It is necessary to expand unrelated donor pool or cord blood banks for the cases lacking HLA-identical sibling donors. Also medical insurances should cover HSCTs for rare diseases as well as for less favorable but novel situations where there are no suitable alternatives.
