The strategy of treating CNS GCTs with upfront chemotherapy according to risk groups resulted in good clinical outcomes and acceptable relapse incidence. However, further modification in the definition of the HR group is needed to reduce long-term complications.

Therapy-related acute myeloid leukemia (t-AML) has a dismal prognosis and is one of the most frequent second malignant neoplasms which could be encountered by pediatric oncologists. Between October 2000 and September 2016, 16 patients who had primary solid tumors were diagnosed with t-AML at the Seoul National University Children's Hospital. The median patient age at the time of diagnosis of their primary solid tumors was 9.6 years (range, 0.1 to 15.4 y), and that of t-AML was 14.0 years (range,

Our study underscores sirolimus's potential for treating complex vascular anomalies in pediatric patients. Challenges associated with optimal treatment duration and concurrent interventions necessitate a comprehensive approach and genetic testing to optimize outcomes.

Wilms tumor is the most common renal malignancy in children. Most of Wilms tumor recurrences occur within 2 years of the first diagnosis. Relapse after 5 years after the first diagnosis is called "late recurrence" and is rare in Wilms tumor. There are few case reports or small series of late recurrence of Wilms tumor. Because of the rarity of late recurrence of Wilms tumor, there is no clear guideline for its management. We describe a case of late recurrence of Wilms tumor as a remote metastasis

Hemophagocytic lymphohistiocytosis (HLH) is a syndrome of pathologic immune activation. It occurs because of severe inflammation due to uncontrolled proliferation of activated lymphocytes and histiocytes, characterized by the production of excessive levels of cytokines. Virus-associated HLH is a well-known entity, and parvovirus B19 is one of the common causes. Parvovirus B19 can also affect blood cell lineages. Therefore, HLH may be accompanied by several diseases such as cytopenia, aplastic an

The therapeutic approach for relapsed/refractory acute lymphoblastic leukemia (ALL) remains to be a challenge. The patient was diagnosed as B-cell ALL at 6 months of age and relapsed for the second time following repeat allogeneic hematopoietic stem cell transplantation (one after first complete remission [CR1] and the other after CR2). During blinatumomab monotherapy, he developed an extramedullary relapse. Finally, the combined therapy with clofarabine, donor lymphocyte infusion, and blinatumo

HDC showed favorable outcomes in patients with non-metastatic OSA and <90% necrosis after neoadjuvant chemotherapy.

The CMV DNA levels that corresponded to 5 pp65-positive cells/2×10 5 WBCs was 900 IU/mL in the HSCT group. The proposed viral load thresholds can be used to guide preemptive therapy in pediatric HSCT recipients, especially in the preengraftment period.

토피라메이트는 다양한 작용기전에 의해 여러 간질 질환, 기분 장애, 편두통 등에 폭넓게 사용되고있는 항간질제로 부작용으로 신석회화증의 발생이가능한 것으로 알려져 있으나 현재까지 국내 소아에서 토피라메이트 사용에 의한 신결석에 대한 보고는없었다. 최근 토피라메이트의 사용 빈도가 증가하고있으므로 향후 이 약제를 사용하는 환자에 대해 신 결석의 발생 가능성에...

Although the survival outcomes of childhood cancer patients have improved, childhood cancer survivors suffer from various degrees of immune dysfunction or delayed immune reconstitution. This study aimed to investigate the effect of Korean Red Ginseng (KRG) on T cell recovery in childhood cancer patients who underwent autologous hematopoietic stem cell transplantation (ASCT) from the perspective of inflammatory and senescent phenotypes. This was a single-arm exploratory trial. The KRG group (n =

It is complicated to establish a consensus on the management and diagnosis of malignancy-triggered hemophagocytic lymphohistiocytosis (M-HLH) in children, as an initial presentation of malignancy is complicated. In this paper, we analyze the clinical characteristics and outcomes of eight pediatric patients in which M-HLH was the initial presentation of malignancy. All patients had hematologic malignancies: three subcutaneous panniculitis-like T-cell lymphomas, two acute lymphoblastic leukemias,
