Peritoneal metastasis (PM) remains a major challenge in patients with gastric cancer (GC) and occurs preferentially in adipose-rich organs, such as the omentum. Adipose-derived stem cells (ASCs) may influence cancer behavior. This study aimed to investigate whether ASCs isolated from the omentum can act as progenitors of cancer-associated fibroblasts (CAFs) and analyze their effects on the cancer stem cell (CSC) niche and the treatment resistance of GC cells.

Article Synopsis
  • Turner syndrome is a genetic disorder caused by the deletion of one X chromosome, leading to diverse karyotypes and phenotypes, but predicting phenotypes remains challenging due to mosaicism.
  • A study included 487 Turner women with non-mosaic X chromosome structural rearrangements and found prevalence rates of short stature (72.4%) and ovarian dysfunction (78.8%) linked to specific deletion groups.
  • Understanding the specific X chromosome breakpoints is crucial for managing Turner syndrome, particularly for predicting and addressing ovarian dysfunction and future fertility issues.

Carotid artery stenting (CAS) has traditionally been performed using the transfemoral approach (TFA). Recently, the transradial approach (TRA) has gained attention for its lower invasiveness and reduced complication risk. This study compares outcomes between two access strategy timeframes, TFA-first and TRA-first, to evaluate how this shift influences outcomes in a real-world setting.

Background: In early-stage endometrial cancer (EC), the treatment of aggressive histological subtypes (endometrioid carcinoma grade 3, serous carcinoma, clear-cell carcinoma, undifferentiated carcinoma, mixed carcinoma, and carcinosarcoma) is controversial. We aimed to investigate the treatment of patients with International Federation of Gynecology and Obstetrics (FIGO) stage IC and stage IIC EC according to the 2023 classification.

Methods: We retrospectively identified patients with FIGO 2023 stage IC, IIC-intermediate risk (IIC-I), and IIC-high risk (IIC-H) EC who underwent adjuvant therapy or observation after surgery at eight medical institutions from 2004 to 2023.
