Maria Natalia Gandur Quiroga: New Insights on Bladder Cancer Invasion

“New Insights on Bladder Cancer Invasion.
Unraveling a hidden player in lympho-vascular invasion in bladder cancer.

  • Researchers uncover how cancer-associated fibroblasts (CAFs) facilitate tumor spread through lymphatic systems in bladder cancer, offering new treatment targets.
  • Key Findings:
  • Specific CAFs reprogram lymphatic endothelial cells, making vessels more susceptible to invasion.
  • These CAFs also remodel the extracellular matrix, aiding cancer cell migration into lymphatic vessels.
  • Methods and Results:
  • Single-cell mRNA sequencing identified a CAF subset crucial for lymphatic invasion.
  • Mouse models confirmed that eliminating these CAFs reduces lymphovascular invasion and lymph node metastasis.
  • Combined treatment with neutralizing antibodies against key CAF markers significantly cut down tumor invasion and spread.
  • Implications:
  • Identifying ITGA11 and CHI3L1 as potential therapeutic targets.
  • Raises questions about the impact on anti-tumor immunity and the timing of treatment for it to be effective.
  • Future Directions:
  • Need for studies on the interaction between CAFs and immune responses, especially concerning BCG bladder treatments.
  • Understanding the generation of these CAFs could lead to preventative strategies for aggressive bladder cancer.”
