Establishment and genomic characterization of the new chordoma cell line Chor-IN-1

Scientific Reports, 2017
Chordomas are rare, slowly growing tumors with high medical need, arising in the axial skeleton from notochord remnants. The transcription factor “brachyury” represents a distinctive molecular marker and a key oncogenic driver of chordomas.

Ependymoma and Chordoma

Neurosurgery, 2020
Abstract Ependymoma and chordoma are 2 tumors that occur throughout the craniospinal axis, and for which the extent of neurosurgical resection has a key prognostic role. Both tumors have distinctive pathologic features, yet can present significant diagnostic challenges to pathologists in cases without classical histology.

Spatiotemporal cellular dynamics of the notochord shape intervertebral disc morphogenesis in the mouse embryo through apoptosis and proliferation

Developmental Dynamics, EarlyView.
Abstract Background The notochord is a midline structure essential for vertebrate embryogenesis, contributing to the development of the nervous system, digestive tract, and vertebral column. In particular, notochord signaling is indispensable for proper patterning and coordinated development of alternating vertebrae and intervertebral discs (IVDs ...

Potential molecular mechanism in self-renewal is associated with miRNA dysregulation in sacral chordoma – A next-generation RNA sequencing study

Heliyon, 2022
Background: Chordoma, the most frequent malignant primary spinal neoplasm, characterized by a high rate of recurrence, is an orphan disease where the clarification of the molecular oncogenesis would be crucial to developing new, effective therapies ...

Viability of Tumor Cells in Bone Dust: Implications for Oncologic Skull Base Surgery

Head &Neck, EarlyView.
ABSTRACT Background Head and neck tumors with skull base involvement may require drilling of tumor infiltrated bone. We hypothesize that bone dust generated during this process contains viable tumor cells that may seed the surgical field. Methods Tumors with gross bone invasion were drilled, and dust was collected for H&E, cell viability analysis, and ...

Transoral Robotic Surgery in Head and Neck Oncology: A Scoping Review of Evidence, Technological Advancements, and Future Trajectories

Journal of Surgical Oncology, EarlyView.
ABSTRACT Robotic surgery has transformed head and neck cancer (HNC) treatment. This scoping review synthesizes evidence on transoral robotic surgery (TORS), focusing on applications, limitations, and future directions. Following PRISMA‐ScR guidelines, this review used the PCC framework (Population: HNC patients; Concept: technological advancements ...

Intraoperative Evaluation of Sarcoma Surgical Margins With Indocyanine Green Fluorescence Imaging: Results From an Observational Study

Journal of Surgical Oncology, EarlyView.
ABSTRACT Introduction Sarcomas are rare malignancies that affect both adults and children. Surgical removal with negative histopathological margins is the foundation of sarcoma treatment. Failure to achieve negative margins puts patients at risk of local recurrence (LR). LR rates range between 10% and 30%.

Applications and prospects of artificial intelligence and digital medicine in pediatric nasal skull base tumors

Pediatric Investigation, EarlyView.
Pediatric nasal skull base tumors present diagnostic and therapeutic challenges due to their deep location, nonspecific symptoms, and the narrow nasal cavity in children. Although artificial intelligence (AI) and digital medicine have advanced early diagnosis, multidisciplinary treatment, and prognosis, their application in these rare tumors remains ...

Perineal chordoma cutis, a rare localization for a rare pathology: a case report and consideration of the literature

PAMJ Clinical Medicine, 2020
The chordoma is a very rare notochordal tumor, the cutaneous localization (chordoma cutis) is even rarer and generally follows a local invasion of the integument even a metastasis. The clinical presentation is non-specific and the diagnosis is often late.
