Sarcoma is a rare cancer with several subtypes; therefore, our understanding of the pathogenesis of sarcoma is limited, and designing effective treatments is difficult. Circulating microRNAs (miRNAs), including exosomal miRNAs, have attracted attention as biomarkers in cancer. However, the roles of miRNAs and exosomes in sarcoma remain unclear. The present analysis of tissue and serum miRNA expression in osteosarcoma, Ewing's sarcoma and dedifferentiated liposarcoma (DDLPS) identified miR-1246, -4532, -4454, -619-5p and -6126 as biomarkers for DDLPS. These miRNAs were highly expressed in human DDLPS cell lines and exosomes, suggesting that they are secreted from DDLPS tissues. The present results suggested that specific miRNAs may be used as biomarkers for early diagnosis or treatment targets in DDLPS.

Scalp masses are common scalp lesions, most of which are benign, with a small proportion being malignant. Scalp sarcomas constitute one category of malignant tumors, primarily including fibrosarcoma, liposarcoma, rhabdomyosarcoma, and leiomyosarcoma. Among these, scalp leiomyosarcoma is exceedingly rare.

Purpose: Liposarcoma (LPS) is the most common soft tissue sarcoma. Well-differentiated LPS (WDLPS) can progress to dedifferentiated LPS (DDLPS), a more aggressive form with higher metastatic potential and poor response to existing therapies. Progress in understanding and treating LPS has been limited.

This report presents the case of a 62-year-old male who presented with a two-month history of right flank pain and decreased appetite. Clinical evaluation revealed a palpable, non-tender mass in the right flank, while laboratory tests demonstrated mild anemia (hemoglobin 9.3 g/dL) with otherwise normal renal function.

Background: Immune checkpoint inhibitors (ICIs) in unselected sarcomas yield limited response rates and tumor control. Long-term responders have however been reported, suggesting a critical challenge in refining patient selection, by identifying reliable predictive factors for response.
Methods: The authors conducted a multicenter, retrospective study of patients with advanced sarcomas treated with ICIs in six French reference sarcoma centers.

Transfer RNAs (tRNAs) are subject to various chemical modifications that influence their stability or function. Adenosine to Inosine (A-to-I) editing in the tRNA anticodon at position A34 is an important modification that expands anticodon-codon recognition at the wobble position and is required for normal mRNA translation. The relevance of tRNA editing in cancer remains unexplored.
