Nat Commun: Sarcoma classification tool based on DNA methylation analysis

Sarcoma, as a heterogeneic tumor, is a malignant cartilage and bone tumor that affects adults, adolescents and children.
because many solid sarcoma lack clear morphological or molecular characteristics, the overall rarity of sarcoma leads to a general lack of experience in diagnosis.
pathologists often rely on changes in identified tumor-specific molecules for diagnosis.
, however, the high degree of difference in diagnosis also results in high rates of difference and misclassifying of feedback received by patients between major institutions and specialized referral centres.
, although specific molecular changes such as gene fusion from trans positions have become the diagnostic criteria for many sarcoma, about half of solid sarcoma lack clear molecular markers.
, there is an urgent need for novel diagnostic methods to fill the diagnostic gaps described above.
the establishment of DNA methylation-based sarcoma reference queues is a key predetermined genetic marker that plays a vital role in normal development and disease.
previous studies have shown that DNA methylation-based analysis shows the potential for diagnosis of cartilage and osteosarcoma subsypes.
the study, researchers aim to develop a DNA methylation-based classification tool for labeling cartilage and osteosarcoma in various subsypes and age groups.
cross-validation of DNA methylated sarcoma classifiers The researchers demonstrated the classification of cartilage and osteosarcoma using machine learning classifier algorithms based on array-generated DNA methylated data.
the classifier was trained with a dataset from 1077 methylated maps from fully pre-indicated cases, including 62...
