However, notwithstanding its limitations, this study firstly established the nomograms to predict the survival of STS patients based on recurrent STS-specific tumor-infiltrating immune cells and ceRNA networks and inferred that the mechanism of hsa-miR-1226-3p regulating MUC1 and dendritic cells resting might play an important role in STS recurrence. Here, MUC1 is linked to neoplasm.
