Fibroblasts could guide the design of personalized treatment for lung cancer patients: Study
BOSTON - Fibroblasts could serve as new key to enhancing personalized treatment for lung cancer patients, find researchers at Massachusetts General Hospital Three subtypes of cancer-associated fibroblasts (CAF) could guide the design of personalized treatment for lung cancer patients.
The study has been published in the journal Cancer Cell .
Solid tumors like non-small-cell lung cancer (NSCLC) contain at least three major cellular components: cancer cells, immune cells and CAFs (which produce a tumor's cellular matrix and secrete signaling molecules). Current personalized cancer treatment approaches predominantly focus on targeting the cancer cells (e.g., oncogene-specific inhibitors) and the immune context (e.g., immune checkpoint blockade) of a tumor. And it had been unclear whether CAFs could be leveraged for designing more personalized treatment.
Unlike cancer cells that are readily distinguishable based on genomic aberrations, the characterization of CAFs' heterogeneity has been historically challenging. As a result, previous attempts to universally target and broadly deplete CAFs rarely improved patient outcomes in the clinic. "We need a new approach to characterize CAFs. Importantly, we need to gain a comprehensive understanding of different CAFs' biological functions and their clinical significance," says lead author Haichuan Hu, MD, PhD, research staff in the Mass General Cancer Center and an instructor in Medicine at Harvard Medical School.
