Background: Myeloablative, high-dose chemotherapy followed by autologous peripheral blood stem cell transplantation (PBSCT) improves outcome in some high-risk malignant solid tumors and lymphomas in children and young adults.

Methods: We performed 16 peripheral blood stem cell (PBSC) harvests in 12 children and 2 young adult patients with a high-risk malignant solid tumor or refractory/relapsed Hodgkin's lymphoma from August 2015 to December 2020. In our chemotherapy mobilization protocol, we used an absolute neutrophil count (ANC) of >1 × 10/L following the nadir after chemotherapy as the criterion for undertaking the apheresis.

Infant-type hemispheric glioma (IHG) is a rare pediatric brain tumor with variable response to chemotherapy and radiotherapy. Molecular insights into IHG can be useful in identifying potentially active targeted therapy. A male fetus was found to have congenital hydrocephalus at the gestational age of 37 weeks.

Article Synopsis
  • A study was conducted on twelve Asian patients with various types of sarcoma who received interval-compressed chemotherapy, alternating between two specific drug regimens (VDC and IE), with support from filgrastim and carboplatin for certain cases.
  • The treatment included a total of 129 cycles, with a median interval of 19 days between cycles, and showed that patients had manageable side effects, like neutropenia and low platelet counts, with a notable percentage experiencing fever.
  • Out of the nine patients with measurable tumors, seven showed a positive response to the treatment, indicating that this chemotherapy approach is feasible for Asian children and young adults with sarcoma.

Background: Childhood cancer survivors are at a high risk of medical consequences of their disease and treatment. There is growing information about the long-term health issues of childhood cancer survivors; however, there are very few studies describing the health care utilization and costs for this unique population. Understanding their utilization of health care services and costs will provide the basis for developing strategies to better serve these individuals and potentially reduce the cost.

There is an increasing number of reported cases with neurological manifestations of COVID-19 in children. Symptoms include headache, general malaise, ageusia, seizure and alterations in consciousness. The differential diagnosis includes several potentially lethal conditions including encephalopathy, encephalitis, intracranial hemorrhage, thrombosis and adrenal crisis.

Article Synopsis
  • Atypical teratoid/rhabdoid tumor (AT/RT) is a rare and aggressive brain cancer primarily affecting young children, with a higher incidence in males and those under 36 months old.
  • * A study in Taiwan identified 47 cases of AT/RT between 1999 and 2014, showing that treatment type and age at diagnosis significantly impacted survival rates.
  • * The findings indicate that patients older than 3 years, those with supratentorial tumors, and those receiving combined treatment had notably improved survival outcomes.

Background: The use of social media in communications regarding cancer prevention is rapidly growing. However, less is known about the general population's social media use related to cancer screening awareness and behavior for different cancers.

Objective: We aimed to examine the relationship between social media use and cancer screening awareness and behavior among people without a cancer diagnosis.

Protein phosphatase 2A (PP2A), a serine/threonine phosphatase involved in the regulation of apoptosis, proliferation, and DNA-damage response, is overexpressed in many cancers, including small cell lung cancer (SCLC). Here we report that LB100, a small molecule inhibitor of PP2A, when combined with platinum-based chemotherapy, synergistically elicited an antitumor response both and with no apparent toxicity. Using inductively coupled plasma mass spectrometry, we determined quantitatively that sensitization via LB100 was mediated by increased uptake of carboplatin in SCLC cells.

Background: Patients with childhood cancer are at increased risk for the development of second cancers.

Methods: A national multicenter survey of second cancers conducted by the Taiwan Pediatric Oncology Group retrieved retrospective data from the database at the Children Cancer Foundation in Taiwan beginning in 1995. The characteristics of second cancers and associations of patient demographic and clinical characteristics with time to death due to a second cancer were analyzed.

Forty-seven patients with metastatic disease at diagnosis or recurrent Ewing sarcoma (EWS) received high-dose chemotherapy (HDC) followed by tandem (n = 20, from February 13, 1997, to October 24, 2002) or single (n = 27, from October 1, 2004, to September 5, 2018) autologous hematopoietic stem cell transplantation (ASCT). To our knowledge, this is the largest single-institution study with sustained long-term follow-up exceeding 10 years. All patients who underwent single ASCT received a novel conditioning regimen with busulfan, melphalan, and topotecan.

Purpose: To improve the event-free survival (EFS) and overall survival (OS) for patients with clear cell sarcoma of the kidney (CCSK) by incorporating cyclophosphamide and etoposide into treatment on National Wilms Tumor Study (NWTS)-5.

Patients And Methods: Patients less than 16 years of age with a centrally confirmed pathological diagnosis of CCSK were eligible for treatment on this prospective single-arm study conducted between August 1995 and June 2002. Staging consisted of CT scans of chest, abdomen, pelvis, bone scan, skeletal survey, and CT or MRI of the head.

Objectives: Brain tumors are found in 1-3% of children with newly onset of seizures. Understanding the impact of seizures on pediatric brain tumors and factors between seizures and brain tumors are crucial. This study aimed to evaluate the association of pediatric brain tumors on seizure occurrence and the relationships between seizures and the diagnosis and prognosis of brain tumors.

Neuroblastoma (NB) is a heterogeneous childhood cancer that requires multiple imaging modalities for accurate staging and surveillances. This study aims to investigate the utility of positron emission tomography (PET) with 18F-fluorodeoxyglucose (FDG) and 18F-fluoro-dihydroxyphenylalanine (FDOPA) in determining the prognosis of NB. During 2007-2014, forty-two NB patients (male:female, 28:14; median age, 2.

Elderly patients with chronic kidney disease (CKD) are at a higher risk of hospitalization for cardiovascular diseases (CVD). Previous studies have showed that influenza vaccination could reduce the risk of recurrent major cardiovascular events in patients with CVD. However, the effects of influenza vaccination on the reduction of first hospitalizations for acute coronary syndrome (ACS) in elderly patients with CKD remain unknown.

Chronic infection with hepatitis B virus (HBV) often causes chronic inflammation of the liver with an increased incidence of hepatocellular carcinoma (HCC). HBV-infected individuals may also have an increased incidence of nonliver cancers. Taking statin or metformin may decrease inflammation and infiltration, which may, as a result, reduce the risk of liver cancer or other major cancers in patients with HBV infection.

Studies have found lower risk of childhood cancer among Asian children. We aim to characterize the recent incidence and incidence-trend of childhood cancer in Taiwan after the National Health Insurance program was launched in March 1995. Data were extracted from the Taiwan Cancer Registry, a population-based database established in 1979.
