Article Synopsis
- Graft-versus-host disease (GVHD) occurs in stem cell transplant patients when donor cells attack the recipient's tissues, leading to complications like oral squamous cell carcinoma (OSCC).
- A systematic review analyzed 23 articles with 81 cases, finding that most patients had myeloid leukemia, with a majority being males around 39 years old, and the tongue was the most common site of GVHD transformation to OSCC.
- OSCCs from GVHD show unique characteristics such as affecting younger individuals, with smoking and alcohol not being significant risk factors, and they generally have a better prognosis, although more research is needed to validate these observations.
