The role of neutrophils and TNF-related apoptosis-inducing ligand (TRAIL) in bacillus Calmette-Guérin (BCG) immunotherapy for urothelial carcinoma of the bladder.
Intravesical Mycobacterium bovis bacillus Calmette-Guérin (BCG) immunotherapy is a highly effective treatment for carcinoma in situ of the bladder, as well as high-risk nonmuscle invasive urothelial carcinoma of the bladder. Despite over 30 years of clinical experience with BCG, the therapy's mechanism has remained enigmatic. Observations regarding the role of neutrophils in BCG immunotherapy have led to exciting discoveries regarding the potential role of tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) in creating the therapeutic benefit of BCG immunotherapy. In this paper, we will review the scope of the disease, highlight our understanding of the role for BCG in urothelial carcinoma of the bladder, explain the recent discoveries regarding the role of neutrophils and TRAIL in therapy, and theorize on potential future areas of research.
