Is interleukin-6 production by bladder tumors upregulated by BCG immunotherapy?
The increase in IL-6 during BCG therapy may be caused by urothelial cells as well as leukocytes. The higher levels seen in nonresponders may be due to either higher grade or persisting tumor.
Data indicate no significant difference in bulbar analgesia and akinesia after RBA between injections of warm and cold anesthetic solutions.
