Small cell osteosarcoma versus fusion-driven round cell sarcomas of bone: retrospective clinical, radiological, pathological, and (epi)genetic comparison with clinical implications
In conclusion, discrimination of SCOS, epigenetically related to COS, versus FDRCS of bone can be challenging but is important due to different biology and therefore therapeutic strategies. Methylation profiling is a reliable and robust diagnostic test especially on decalcified FFPE material. Subsequent fusion gene analysis and/or use of specific immunohistochemical surrogate markers can be used to substantiate the diagnosis. (Source: Virchows Archiv)

Cancers, Vol. 16, Pages 718: Patterns of Temporal Lobe Reaction and Radiation Necrosis after Particle Radiotherapy in Patients with Skull Base Chordoma and Chondrosarcoma & mdash;A Single-Center Experience
Conclusion: Temporal lobe reactions are a common side effect after particle therapy of the skull base. We were able to develop a multivariate model, which predicted radiation reactions with a specificity of 99% and a sensitivity of 52.2%. (Source: Cancers)

A retrospective external validation study of the Birmingham Atypical Cartilage Tumour Imaging Protocol (BACTIP) for the management of solitary central cartilage tumours of the proximal humerus and around the knee
ConclusionAlthough promising as a useful tool for management/follow-up of CCTs of the proximal humerus, distal femur, and proximal tibia, five ACTs and one chondrosarcoma grade II were discharged, potentially inducing diagnostic delay, which could be reduced by adapting BACTIP cut-off values.Clinical relevance statementMostly, Birmingham Atypical Cartilage Tumour Imaging Protocol (BACTIP) assesses central cartilage tumours of the proximal humerus and the knee correctly. Both when using the BACTIP and when adapting cut-offs, caution should be taken for the trade-off between underdiagnosis/potential diagnostic delay in chond...

Association of MiRNA and Bone Tumors: Future Therapeutic Inroads
Curr Med Chem. 2024 Jan 30. doi: 10.2174/0109298673284932231226110754. Online ahead of print.ABSTRACTSmall endogenous non-coding RNA molecules known as micro-ribonucleic acids (miRNAs) control post-transcriptional gene regulation. A change in miRNA expression is related to various diseases, including bone tumors. Benign bone tumors are categorized based on matrix production and predominant cell type. Osteochondromas and giant cell tumors are among the most common bone tumors. Interestingly, miRNAs can function as either tumor suppressor genes or oncogenes, thereby determining the fate of a tumor. In the present review, we ...

Successful management of a pregnancy complicated by ollier disease and coagulation factors deficiency – A rare case report
Introduction: Ollier disease (OD) is a rare, non-hereditary bone disease characterized by multiple enchondromas with a predilection for the appendicular skeleton or pelvis. Its prevalence is estimated at 1:100,000 people. Patients with OD have a 20-53% increased risk of malignant transformation into chondrosarcoma, visceral, hematologic or gonadal-related malignancies.This is the first case described in Poland and the third in the world of a pregnant patient with Ollier disease.

A Systematic Review of Adjuvant Chemotherapy in Localized Dedifferentiated Chondrosarcoma
Curr Oncol. 2024 Jan 19;31(1):566-578. doi: 10.3390/curroncol31010040.ABSTRACTDedifferentiated chondrosarcoma (DDCS) is a high-grade subtype of chondrosarcoma with the bimorphic histological appearance of a conventional chondrosarcoma component with abrupt transition to a high-grade, non-cartilaginous sarcoma. DDCS can be radiographically divided into central and peripheral types. Wide resection is currently the main therapeutic option for localized DDCS. Moreover, the effectiveness of adjuvant chemotherapy remains controversial. Therefore, we performed a systematic review of available evidence to evaluate the effect of ad...

The complete anterior petrosectomy: an expanded extended-middle fossa approach with removal of the infratrigeminal petrous apex and drilling of the lateral clivus
J Neurosurg. 2024 Jan 19:1-9. doi: 10.3171/2023.11.JNS231303. Online ahead of print.ABSTRACTIntradural exposure in the extended middle fossa anterior transpetrosal approach is traditionally limited to the inferior petrosal sinus inferomedially. Expanding bone removal of the petrous apex around the petrous internal carotid artery (ICA), underneath the trigeminal ganglion/mandibular nerve, and into the lateral component of the clivus can significantly expand the limits of this approach beyond the inferior petrosal sinus and allows for exposure of the midline structures, aspects of the contralateral inferior clival region, an...

GSE184118 Single-cell RNA sequencing analysis reveals CHOP as an early marker for conventional chondrosarcoma
Contributors : Zezhuo Su ; Joshua Ho ; Kelvin CheungSeries Type : Expression profiling by high throughput sequencingOrganism : Homo sapiensChondrosarcoma is the malignant form of chondrogenic tumors that consist of cartilage producing cells. Chondrosarcoam can arise from benign chondrogenic lesion. Benign chondrogenic tumors are normally managed conservatively, while surgical intervention can improve clinical outcomes of patients with chondrosarcoma. Clinical decision making is mainly based on the grade of the chondrogenic tumor. However, interobserver viability is high. There is currently no clear molecular for the gra...
