Intravesical recombinant tumor necrosis factor in the treatment of superficial bladder cancer: an Eastern Cooperative Oncology Group study.

We tested and proved the safety of recombinant human tumor necrosis factor given intravesically weekly for 11 weeks (dwell time 2 hours) for the treatment of superficial bladder cancer in 8 men and 1 woman 46 to 87 years old (mean age 69 years). Cohorts of 3 patients received 200, 400 and 1,000 micrograms. recombinant human tumor necrosis factor. The maximal tolerated dose was not achieved. There were 9 episodes of urological symptoms, 8 of flu-like symptoms, 4 of headache and 3 of chest tightness. Hematological and gastrointestinal toxicities were minor, and no renal toxicity was encountered. Recombinant human tumor necrosis factor was safe to administer at doses up to 1,000 micrograms. We hope that recombinant human tumor necrosis factor in conjunction with other antitumor agents will lead to a new, effective treatment for superficial bladder cancer.
