摘要

Background and Purpose: Following preoperative radiotherapy prior to ablative surgery of squamous epithelial cell carcinomas of the head and neck region, wound-healing disorders occur. Previous experimental studies showed altered expression of transforming growth factor-(TGF-) isoforms following surgery in irradiated graft beds. Altered levels of TGF-1 are reported to promote fibrosis and to suppress vascularization during wound healing, whereas expression of TGF- receptor-III (TGF-R-III) is associated with vascularization. The aim of the study was to analyze the influence of anti-TGF-1 treatment on TGF-R-III-associated vascularization in the transition area between irradiated graft bed and graft.
