The serum level of tumor necrosis factor (TNF) was significantly increased in 17 patients after IL-2 therapy. Recurrence occurred in 4 patients during the follow-up period of 10-18 months. The basic level of serum TNF was low and was not increased or even decreased after IL-2 in these patients. On the contrary, recurrence did not occur in another 5 patients with low basic level of TNF, but it was significantly increased after treatment of IL-2. TNF played a key role in preventing the recurrence of bladder cancer. The patients who had low basic level of TNF, which did not markedly increase or even decrease after IL-2 therapy were at high risk of recurrenc展开更多
