Undifferentiated sarcomas characterized by a primitive monomorphic round to spindle cell phenotype and often non-specific immunoprofile remain difficult to subclassify outside molecular analysis. The increased application of RNA sequencing in clinical practice led to significant advances and discoveries of novel gene fusions that furthered our understanding and refined classification of otherwise undifferentiated neoplasms. In this study, we report an undifferentiated round to spindle cell sarcoma arising in the femur of a 34-year-old female.

The glucagon-like peptide-1 receptor agonists (GLP-1RA) are among the newest treatment options available for managing of type 2 diabetes mellitus and slowing the progression of diabetes kidney disease (DKD). Subcutaneous (SC) semaglutide (Ozempic) is a GLP-1RA with an extended half-life of approximately 1 week. GLP-1RA are highly effective in improving glycemic control and also show other beneficial effects such as increased natriuresis; decreased blood pressure and albuminuria; reduction of oxidative stress and inflammation; delay of gastric emptying and suppress appetite; the latter may result in significant weight loss.

Article Synopsis
  • - The study investigates how cholesteryl ester (CE) levels within breast tumors relate to various cancer characteristics in 30 human breast cancer samples, divided into three types: luminal-A, Her-2, and triple negative tumors.
  • - Analysis revealed that tumors rich in CE had a higher histologic grade and showed increased levels of certain markers associated with tumor growth and invasion, such as LDLR and SCARB1.
  • - The findings suggest that high CE accumulation in tumors is correlated with more aggressive cancer behavior and poorer clinical outcomes, indicating potential new targets for cancer treatment.

Article Synopsis
  • The study explored the relationship between HER2, TOP2A, and CEP17 genetic markers and the effectiveness of anthracycline chemotherapy in patients with breast cancer.
  • Out of 140 patients, only 13 (9.3%) achieved a complete response to treatment, with CEP17 duplication showing a significant correlation to this positive response.
  • While CEP17 duplication and TOP2A amplification combined indicated a strong association with treatment response, HER2 amplification did not correlate with successful outcomes or prognosis.

Molecular differentiation between invasive lobular carcinomas (ILCs) and invasive ductal carcinomas (IDCs) of the breast has not been well defined. We investigated gene expression differences between ILCs and IDCs and their correlation with variations in invasiveness and tumor growth. Total RNA was isolated from 30 frozen tumor samples: 10 from ILCs and 20 from IDCs.

Unlabelled: The mechanism of progression from ductal carcinoma in situ (DCIS) to invasive ductal carcinoma (IDC) remains largely unknown. We compared gene expression in tumors with simultaneous DCIS and IDC to decipher how diverse proteins participate in the local invasive process.Twenty frozen tumor specimens with concurrent, but separated, DCIS and IDC were microdissected and evaluated.
