Pediatric renal and suprarenal cancers are relatively rare malignancies, but are not without significant consequence to both the patient and caretakers. These tumors are often found incidentally and present as large abdominal masses. Standard of care management involves surgical excision of the mass, but contemporary treatment guidelines advocate for use of neoadjuvant or adjuvant chemotherapy for advanced stage disease, such as those cases with lymph node involvement (LNI). However, LNI detection is based primarily on surgical pathology and performing extended lymph node dissection can add significant morbidity to a surgical case...

Diffuse intrinsic pontine glioma (DIPG) is one of the most devastating types of pediatric cancer. Accumulating evidence suggests that the dysregulated expression of long non-coding (lnc)-RNAs is associated with various pathologies of the CNS. However, the expression patterns and prognostic roles of lncRNAs in DIPG have not yet been systematically determined. In the present study, lncRNA expression profiles were obtained from the Gene Expression Omnibus (GEO) database using the lncRNA-mining approach and a differential expression analysis for lncRNAs was performed between DIPG and low-grade brainstem glioma and DIPG and normal pediatric brainstem tissue...

BACKGROUND: Regional lymph node (LN) metastasis at the time of presentation plays a significant role in predicting recurrence in patients with papillary thyroid cancer (PTC). Multiple studies in the adult population have demonstrated that the lymph node ratio (LNR) in both the central and lateral neck can improve the accuracy of recurrence prediction, but this ratio has not been studied in the pediatric population. In this study, we sought to investigate the LNR in the central and lateral compartments as a prognostic predictor for recurrence in pediatric patients with PTC...

The AMP-activated protein kinase (AMPK) is a sensor of cellular energy status that has a dual role in cancer, i.e., pro- or anti-tumorigenic, depending on the context. In medulloblastoma, the most frequent malignant pediatric brain tumor, several in vitro studies previously showed that AMPK suppresses tumor cell growth. The role of AMPK in this disease context remains to be tested in vivo. Here, we investigate loss of AMPKα2 in a genetically engineered mouse model of sonic hedgehog (SHH)-medulloblastoma. In contrast to previous reports, our study reveals that AMPKα2 KO impairs SHH medulloblastoma tumorigenesis...

INTRODUCTION: Thyroid cancer is the most common pediatric endocrine cancer; accurate diagnosis and prompt management of pediatric thyroid nodules is critical. The McGill Thyroid Nodule Score (MTNS), based upon clinical, ultrasound (US), and cytology criteria has recently been modified and studied in a pilot pediatric group with good results. We aim to describe the diagnostic accuracy of the pediatric modified MTNS (PMTNS) in a large pediatric cohort. METHODS: We utilized an established retrospective cohort between 1996 and 2015 of 99 patients ≤ 21 years old with 131 thyroid nodules...

PURPOSE: Acute lymphoblastic leukemia (ALL) is the most common type of cancer in children, and despite the high rate of cure (over 80%) it still has a big impact on morbidity and mortality. The Transducin-like enhancer of split 1 (TLE1), a transcriptional corepressor, has been described as dysregulated and recently emerged as a tumor marker in several cancer types, including hematologic malignancies. METHODS: In the present study TLE1 gene expression was evaluated by RT-qPCR...

BACKGROUND: Crohn's disease (CD) is highly heterogeneous, due in large part to variability in cellular processes that underlie the natural history of CD, thereby confounding effective therapy. There is a critical need to advance understanding of the cellular mechanisms that drive CD heterogeneity. METHODS: We performed small RNA sequencing of adult colon tissue from CD and NIBD controls. Colonic epithelial cells and immune cells were isolated from colonic tissues, and microRNA-31 (miR-31) expression was measured...

Secretory breast carcinoma (SBC) is a rare form of breast cancer found in both children and adults, and is the most common breast cancer in the pediatric population. Although SBC usually carries a favorable prognosis, there have been reported cases of axillary and distant metastases. Surgery is the primary mode of treatment, however, there exists variability within the literature surrounding the management of SBC. We report a case of an 8-year-old girl who presented with a firm, mobile, palpable breast mass...

Accessibility to immunohistochemistry (IHC) is invaluable to proper diagnosis and treatment of pediatric patients with malignant neoplasms. Whereas IHC is widely available in anatomic pathology laboratories in high-income countries, access to it in anatomic pathology laboratories of low- and middle-income countries remains a struggle, with many limitations. To advance the quality of the pathology service offered to children with cancer in areas with limited resources, a 5-day pathology training workshop was offered to pathologists and histotechnologists from various countries of the Central American and Caribbean region...

PURPOSE: Approximately 80% of cases of childhood cancer occur in low- and middle-income countries and are associated with high mortality rates. Assessing outcomes is essential for designing effective strategies to improve outcomes equally worldwide. We implemented a real-time surveillance system, VIGICANCER, embedded in a population-based cancer registry (PBCR) to assess childhood cancer outcomes. METHODS: VIGICANCER was established in 2009 as an integral part of Cali's PBCR to collect real-time data on outcomes of patients (age < 19 years) with a new diagnosis of cancer treated in pediatric oncology units in Cali, Colombia...

PURPOSE: The management of central nervous system tumors is challenging in low- and middle-income countries. Little is known about applicability of twinning initiatives with high-income countries in neuro-oncology. In 2004, a monthly neuro-oncology video-teleconference program was started between King Hussein Cancer Center (Amman, Jordan) and the Hospital for Sick Children (Toronto, Ontario, Canada). More than 100 conferences were held and > 400 cases were discussed. The aim of this work was to assess the sustainability of such an initiative and the evolution of the impact over time...

Ultrasound-guided venous access is becoming a standard technique in many centers worldwide. In small veins and in the pediatric population, successful venous puncture is sometimes followed by resistance in passing the wire. The needle seems to miss the small vein during syringe dismounting, wire mounting and wire advancement through the needle. This work describes a "wire-loaded puncture" technique as a solution for this problem. PATIENTS AND METHODS: Paediatric cancer patients who needed venous access for different indications were included in the study...
