Clinical evaluation of the CrossNN DNA methylation classifier for central nervous system tumors

Brain Pathology, EarlyView.
CrossNN demonstrated non‐inferiority to the Heidelberg CNS Tumor Methylation Classifier. A dual‐classifier approach increased the number of clinically informative classifications with correct tumor type assignment while maintaining a low rate of incorrect predictions.

Uterine Cervix Metastasis of Myxopapillary Ependymoma Originated from the Spinal Cord

Balkan Medical Journal, 2016
Background: Myxopapillary ependymomas are well differentiated low-grade tumors which have been documented to local or distant metastasis. In the literature, this is a unique case of myxopapillary ependymoma with metastasis to the uterine cervix. Here, we

PTEN homozygous deletion is a negative prognostic factor in tumor treating fields‐treated glioblastoma, IDH wildtype patients

Brain Pathology, EarlyView.
In a molecularly confirmed cohort of 64 newly diagnosed, TTFields‐treated glioblastomas, IDH‐wildtype, homozygous PTEN deletion was associated with markedly shorter overall survival (368 vs. 603 days) and remained an independent adverse prognostic factor.

Gliomas with pleomorphic and pseudopapillary features (GPAP) are circumscribed tumors with targetable mutations, prolonged survival, and frequent tumor predisposition

Brain Pathology, EarlyView.
DNA methylation profiling identifies GPAP as a distinct circumscribed glioma with a characteristic expansive, multicystic radiological appearance, pleomorphic and pseudopapillary histology, a recognizable CNV profile, druggable molecular alterations, and recurrent cancer predisposition syndromes.

Evaluating Fine Needle Aspiration Cytology for Diagnostics of Soft Tissue and Bone Tumours

Cytopathology, EarlyView.
Systematic comparison of needle aspiration cytology and histopathology for 503 tumours in soft tissue and bone showed high concordance (positive predictive value 94%–100%, negative predictive value 83%–89%). In this original study, the authors show that FNAC is a safe and non‐invasive method for diagnosing suspected sarcomas, with the main objective to
