Background/aim: Due to the absence of screening protocols, high-grade serous ovarian cancer (HGSOC) patients are frequently diagnosed at an advanced stage, which significantly reduces the survival rate. Moreover, relapse occurs in approximately 70% of HGSOC patients after primary treatment. Predicting resistance to primary chemotherapy remains a challenge.

Article Synopsis
  • Recent studies show a partial loss of SMARCB1/INI1 expression in skull base chordomas, suggesting potential treatment options for these tumors; this study focused on 89 patients with spinal chordomas.
  • The analysis found that 41.6% of patients exhibited partial SMARCB1/INI1 loss, primarily due to a deletion on chromosome 22, with significant implications for tumor location and surgical outcomes.
  • Key findings indicated that tumor location (specifically in the sacrococcygeal region) and adequate surgical margins were linked to better disease-free survival rates, highlighting important factors for patient prognosis.

Introduction: Extraskeletal Ewing sarcoma (EEwS) is a rare malignant tumor, and current international recommendations indicate systemic and local treatment like bone Ewing sarcoma (BEwS); to the best of our knowledge, very few studies tried to explore the clinical and genetic characteristics of this tumor, and the most appropriate treatment strategy remains uncertain.

Methods: We reviewed 35 EEwS cases enrolled at Rizzoli Orthopedic Institute in Bologna, Italy, between 1988-2022. We performed RNA sequencing in 18 Ewing sarcoma cases, including 12 BEwSs and 6 EEwSs.

Neuroblastoma (NB) is the most commonly diagnosed extracranial solid tumor in children, accounting for 15% of all childhood cancer deaths. Although the 5-year survival rate of patients with a high-risk disease has increased in recent decades, NB remains a challenge in pediatric oncology, and the identification of novel potential therapeutic targets and agents is an urgent clinical need. The RNA-binding protein LIN28B has been identified as an oncogene in NB and is associated with a poor prognosis.

Background: A BCL6 corepressor (BCOR) gene alteration is a genetic signature of rare subsets of sarcomas. The identification of this alteration has recently contributed to the definition of new entities in the current WHO (2020) classification of soft tissue and bone tumours. We retrospectively examined cases of BCOR-rearranged sarcoma (BRS) to assess the reliability of the BCOR FISH analysis using an IVD (in vitro diagnostic) probe.

Article Synopsis
  • The RNA-binding protein LIN28B influences developmental timing and stem cell identity by suppressing let-7 microRNAs.
  • Overexpressing LIN28B in neural crest cells (NCC) in developing embryos leads to reduced differentiation into sympathoadrenal cells and increased NCC migration, illustrated in two vertebrate models: Xenopus laevis and Danio rerio.
  • The study finds that LIN28B overexpression is linked to neuroblastoma development and enhances tumor cell invasion, affecting mechanisms both dependent and independent of let-7a microRNAs.

Extra-axial chordoma is an exceedingly rare tumor, with only 28 cases reported in the literature to date. Axial and extra-axial chordoma exhibits complete morphologic and immunophenotypic (expression of brachyury) overlap. However, in consideration of the non-canonical presentation, extra-axial chordoma is under-recognized and often misdiagnosed, most often as extraskeletal myxoid chondrosarcoma or myoepithelioma.
