Abstract
BACKGROUND Super-enhancers (SEs) typically govern the expression of critical oncogenes and play a fundamental role in the initiation and progression of cancer. Focusing on genes that are abnormally regulated by SE in cancer may be a new strategy for understanding pathogenesis. In the context of this investigation, we have identified a previously unreported SE-driven gene IRF2BP2 in neuroblastoma (NB). METHODS The expression and prognostic value of IRF2BP2 were detected in public databases and clinical samples. The effect of IRF2BP2 on NB cell growth and apoptosis was evaluated through in vivo and in vitro functional loss experiments. The molecular mechanism of IRF2BP2 was investigated by the study of chromatin regulatory regions and transcriptome sequencing. RESULTS The sustained high expression of IRF2BP2 results from the activation of a novel SE established by NB master transcription factors MYCN, MEIS2, and HAND2, and they form a new complex that regulates the gene network associated with the proliferation of NB cell populations. We also observed a significant enrichment of the AP-1 family at the binding sites of IRF2BP2. Remarkably, within NB cells, AP-1 plays a pivotal role in shaping the chromatin accessibility landscape, thereby exposing the binding site for IRF2BP2. This orchestrated action enables AP-1 and IRF2BP2 to collaboratively stimulate the expression of the NB susceptibility gene ALK, thereby upholding the highly proliferative phenotype characteristic of NB. CONCLUSIONS Our findings indicate that SE-driven IRF2BP2 can bind to AP-1 to maintain the survival of tumor cells via regulating chromatin accessibility of the NB susceptibility gene ALK.

The relationship between circulating tumor cells in peripheral blood and clinical characteristics of pediatric neuroblastoma and prognostic evaluation. Pediatr Hematol Oncol 2024:1-15.

Abstract
This study investigates the correlation between circulating tumor cells (CTCs) in peripheral blood and the clinical characteristics and prognosis of advanced pediatric neuroblastoma (NB). We conducted a retrospective analysis of 144 children with advanced NB who underwent comprehensive treatment. Detailed clinical data were collected, and CTCs were detected using a negative enrichment method combined with immunofluorescence technology. Prognostic evaluation criteria and cutoff values for CTCs were established using ROC curve analysis. Univariate and Cox multivariate regression analyses identified independent risk factors impacting prognosis. Patients were categorized into high and low-expression groups based on optimal cutoff values determined with X-tile software. The high expression group had a significantly higher incidence of disease progression (p < 0.001), maximum tumor diameter ≥10 cm (p = 0.004), undifferentiated subtype (p = 0.034), and stage IV disease (p = 0.007) compared to the low expression group. CTCs were notably higher in patients with progression compared to those with mitigation (p < 0.001), in those with maximum tumor diameter ≥10 cm compared to <10 cm (p < 0.001), and in stage IV compared to stage III patients (p = 0.036). The AUC values for maximum tumor diameter, degree of differentiation, and tumor stage were 0.703, 0.669, 0.574, and 0.598, respectively. The detection of CTCs provides significant insights into the clinical characteristics and prognosis of advanced pediatric NB, highlighting its potential as a prognostic tool.

Abstract
A 31-year-old male came to emergency department with acute abdominal pain from the right flank, diaphoresis and, palpitations. Contrasted abdominal CT revealed a tumor dependent from right adrenal gland and kidney. A laparoscopic radical nephrectomy was made to resect the tumor and pain relief. Pathological analysis reported poorly differentiated neuroblastoma from the right adrenal gland without involvement to kidney and ureter. The patient was sent to oncology clinic to continue with chemotherapy treatment. This is the third case of adult neuroblastoma reported in South America. Adult neuroblastoma is an uncommon cause of malignant neoplasm with an exceptional incidence reported.

Abstract
Teratomas are defined by the presence of cell types from different germ layers, they typically involve the gonads or the sacrococcygeal region and are rarely retroperitoneal. Prenatally detected adrenal teratomas are extremely uncommon. Aim of this paper is to share our experience with an adrenal antenatal mass initially diagnosed as a left adrenal neuroblastoma that turned out to be a mature teratoma after microscopical examination. We present the case of a male fetus with antenatal diagnosis of a left adrenal cystic image at the 22nd week of amenorrhea. The fetal magnetic resonance imaging showed a non-calcified cystic mass of the left adrenal gland, compatible with a neuroblastoma. At birth an ultrasound confirmed the presence of an anechogenic lesion of the left adrenal gland. The infant was closely monitored during his first year and in the absence of significant regression of the adrenal mass, it was decided to perform a laparoscopic left adrenalectomy. Unexpectedly, the final pathological diagnosis was mature cystic adrenal teratoma. In conclusion, an adrenal mass diagnosed antenatally is generally a hemorrhage or a neuroblastoma. Adrenal teratomas are very rare and those diagnosed antenatally even more. At present, we have no clinical, biological, or radiological evidence to suspect them before surgical removal. There are only two other cases of unexpected adrenal teratoma in infants described in Literature.
