Abstract

Intravesical therapy is currently being used in the management of superficial transitional cell carcinoma of the urinary bladder. Its main objectives constitute treatment of existing or residual tumor, prevention of recurrence of tumor, prevention of disease progression, and prolongation of survival. The initial clinical stage and grade of bladder cancer remains the main determinant factors in survival, irrespective of the treatment. Intravesical chemotherapy has shown a decrease in short-term tumor recurrence rates, but has had no positive impact on disease progression or prolongation of survival. Bacillus Calmette-Guerin (BCG) immunotherapy remains the most effective treatment and prophylaxis modality for superficial bladder cancer and results in a positive outcome on tumor recurrence, disease progression, and prolongation of survival. Although therapy by intravesical BCG instillation is widely accepted as the therapy of choice, the development of BCG-resistant bladder cancer remains a major setback. Thus, there is an urgent need for a major effective therapy for bladder cancer patients who are unresponsive to BCG therapy. This review summarizes briefly the recent highlights and advances in the therapy of superficial bladder cancer. This review also describes our preliminary findings achieved in in vitro model systems and our proposed new approaches to overcome the resistance of bladder cancer cells and render bladder cancer cells responsive to these new therapies.
