Toxicity of local, continuous and cyclic, high-dose bladder perfusion with recombinant and natural interleukin-2 in advanced cancer of the urinary bladder

Biologic response modifiers in the management of superficial bladder cancer

For the treatment of existing transitional-cell carcinoma or for prophylaxis of recurrent disease, intravesical therapy should be chosen according to stage. Papillary disease (stages Ta, Tl) may be treated effectively either with an alkylating agent or with bacillus Calmette-Guérin (BCG). BCG is the agent of choice for the treatment of Hat carcinoma in situ (Tis), with the recommended treatment course comprising 12 weekly and 12 monthly instillations. Intravesical interferon and many of the other biologic response modifiers mentioned herein may be effective for patients with Ta disease who have failed BCG therapy.
