Meagan R Doyle, J Martin Johnston
Li-Fraumeni syndrome is an autosomal dominant cancer syndrome characterized by pathogenic variants in the TP53 gene on chromosome 17. The most common cancers in Li-Fraumeni kindreds include sarcomas, breast cancer, brain tumors, and adrenocortical carcinoma. We report a 9-month-old male who was diagnosed with an adrenocortical tumor and later found to harbor a novel TP53 c.559 G > C germline variant, resulting in p.Gly187Arg. Family history included early-onset breast cancer in his paternal grandmother and paternal great-grandfather, as well as colon cancer at age 31 in a paternal cousin...

Wilms tumor (WT) has a survival rate above 90% in high income countries. Reported survival rates in sub-Saharan Africa are much lower and long-term outcome is not well known as follow-up is challenging. In Blantyre, Malawi, an adapted WT treatment guideline with preoperative chemotherapy, supportive care, and strategies to enable children and parents to complete treatment was introduced in 2006. Between 2006 and 2011, 73 children with a unilateral WT were treated. Follow-up, including home visits when needed, was done...

Primary bone marrow lymphoma (PBML) is hard to diagnose in children, due to the difficult identification of malignant cells in bone marrow. The first case, a 5-year-old boy, showed knee swelling with an intermittent fever. The second case, a 12-year-old girl, showed fever of unknown origin without lymphadenopathy or hepatosplenomegaly. In both cases, the diagnosis was not confirmed despite the repeated bone marrow aspirations. Finally, bone marrow aspiration and biopsy at the positive site by positron emission tomography (PET)-CT contributed to definitive diagnosis of PBML...

Glycogen storage disease (GSD) type 1 is a rare autosomal recessive inherited condition. The 1b subtype comprises the minority of cases, with an estimated prevalence of 1 in 500,000 children. Patients with glycogen storage disease type 1b are often treated with granulocyte colony stimulating factor (G-CSF) for prolonged periods to improve symptoms of inflammatory bowel disease (IBD) and in the face of severe neutropenia to decrease risk of infection. Long-term G-CSF treatment may result in an increased risk of myelodysplastic syndrome (MDS) or acute myeloid leukemia (AML) possibly due to increased marrow stress resulting in telomere shortening...

REVIEW
Gaya Narendran, Lianne Tomfohr, Fiona Schulte
Compared to the general pediatric population, pediatric cancer patients are at increased risk of experiencing depressive symptoms during and after their treatment. Clinically, there exist few resources to guide health care professionals in the care of children with cancer who report depressive symptomatology. Pediatric cancer patients experience unique inflammatory changes secondary to their disease and accompanying treatments. It has been reported that inflammatory changes in the context of illness are related to cytokine dysregulation which in turn may influence the expression of depressive symptoms...

Acute lymphoblastic leukemia (ALL) is the most common childhood malignancy. Modern treatment protocols allow achievement of long-term event-free survival rates in up to 85% of cases, although the treatment response varies among different patient groups. It is hypothesized that treatment response is influenced by the IL15 gene variations, although research results are conflicting. To analyze IL15 gene variations influence treatment response, clinical course and the risk of developing ALL we performed a case-control and family-based study...

Nodular sclerosing Hodgkin lymphoma (HL) has an excellent prognosis in children. The syncytial variant (SV) of HL in adults represents a clinic pathologic entity with a worse outcome. We report the clinical features and the course of the disease of three children with refractory HL. The three patients with SV were analyzed in a retrospective multi-institutional study conducted in Israel in 51 children diagnosed with refractory or recurrent HL between 1997 and 2014. All the three children developed multiple recurrences soon after diagnosis...
