Background: Minimally invasive surgery for paediatric adrenal tumours has evolved, but robot-assisted laparoscopic adrenalectomy (RALA) in children remains poorly studied. The current prospective study aims to demonstrate the safety and efficacy of RALA in treating children with adrenal tumours.

Methods: A prospective institutional analysis of children presenting with neuroblastic and endocrine tumours treated with RALA was undertaken over a six year-period.

Article Synopsis
  • Pancreatic neuroendocrine neoplasms (pNENs) are rare in children, with a study examining cases between 2011 and 2020 to understand their clinical presentation and behavior.
  • The study analyzed 15 patients, mostly adolescents, and found that a significant number had cancer predisposition syndromes, with some diagnosed through screening.
  • Results showed that patients with low-grade tumors had better survival rates, while those with high-grade or metastatic cancers faced poorer outcomes, highlighting the need for improved treatment strategies for severe cases.

Very rare tumors are usually divided into two groups: One includes tumors that are rare among both children and adults; the other one encompasses tumors that frequently occur in adults but are rarely observed in children. In this review, we focus on adrenocortical tumors, neuroendocrine tumors of the appendix, pheochromocytoma and paraganglioma, pancreatoblastoma and solid pseudopapillary tumors of the pancreas, with special attention to the role of surgery as main curative intervention or as part of the multimodal treatment.

Hepatocellular adenomas (HCAs) are rare benign liver tumours. Predisposing factors and complication rates appear to differ among children and adults. In the present study, we aimed to systematically characterise paediatric HCAs and determine their course, complications, and management.

Article Synopsis
  • Hepatoblastomas show varied cell types that affect patient outcomes, but the reasons for this diversity are not well understood.
  • Researchers employed a single-cell analysis to explore the molecular factors contributing to these different cell states, revealing a spectrum of differentiation between liver cell types.
  • They discovered that specific genetic subclones within tumors exhibit unique levels of cellular flexibility, with certain subclones being more aggressive and responsive to chemotherapy due to the overexpression of specific genes.

Background: Hepatoblastoma is the most frequent pediatric liver cancer. The current treatments lead to 80% of survival rate at 5 years. In this study, we evaluated the clinical relevance of molecular features to identify patients at risk of chemoresistance, relapse and death of disease.

Pediatric liver tumors are very rare tumors with the most common diagnosis being hepatoblastoma. While hepatoblastomas are predominantly sporadic, around 15% of cases develop as part of predisposition syndromes such as Beckwith-Wiedemann (11p15.5 locus altered).

Background: Inflammatory myofibroblastic tumors (IMT) are rare, intermediate malignant tumors harboring frequent somatic molecular rearrangements. The management of IMT has not been standardized.

Methods: A retrospective multicenter study was conducted on all pediatric patients treated for IMT between 2000 and 2019.

Background: ABO-incompatible (ABOi) living donor liver transplantation (LDLT) has been proposed to compensate for donor shortage. To date, few studies have reported detailed ABOi LDLT results in large series of pediatric patients. C4d complement deposition in graft capillaries has been reported to be associated with antibody-mediated rejection in solid organ transplantation.

Surgical treatment of biliary atresia (BA) is still based on sequential strategy with Kasai hepatoportoenterostomy (KP) followed by liver transplantation (LT), in case of complicated secondary biliary cirrhosis. Concerns have been expressed regarding the risks of LT related to previous KP, suggesting primary LT as an exclusive treatment of BA. Single-center retrospective analysis including 393 pediatric patients who underwent LT for BA from 1993 to 2018, categorized into two groups: with (KP) or without (NoKP) previous KP.

Background: Living donor liver transplantation is a treatment option for unresectable hepatic tumors in children.

Methods: We enrolled 45 living donor transplantations performed between 1993 and 2018 for liver malignacies, which included hepatoblastoma (n = 33), hepatocellular carcinoma (n = 10), hepatic angiosarcoma (n = 1), and rhabdomyosarcoma (n = 1).

Results: No mortality or major morbidities were encountered in any donor, and the complication rate was 9%.

Background: Pediatric LT are at particular risk of HAT, and its management still constitutes a matter of debate. Our purpose was to study predisposing factors and outcome of HAT post-LT, including the impact of surgical revisions on survival and biliary complications.

Methods: Among 882 primary pediatric LT performed between 1993 and 2015, 36 HAT were encountered (4.

Introduction: Parathyroid cysts are infrequently encountered and have a variable presentation pattern depending on their size, location and secreting character.

Patients And Methods: We report two cases of parathyroid cysts characterized by their uncommon clinical presentation.

Results: In the first case the patient presented with a large cervical cystic mass without hypercalcemia, while in the second case, the patient experienced a hypercalcemic crisis associated with acute renal failure.

pT, under mono- and infratherapeutic calcineurin inhibition, may constitute an optimal condition combining graft acceptance with low IS load and minimal IS-related toxicity. We reviewed 171 pediatric (<15.0 yr) survivors beyond one yr after LT, transplanted between April 1999 and June 2007 under tacrolimus-based regimens (median follow-up post-LT: 6.
