Treatment of superficial bladder cancer with intravesical Bacillus Calmette-Guérin (BCG) has a more reduction potential than surgery in tumor recurrence rate. BCG, the gold standard for nonmuscle invasive bladder cancer, is manufactured from different strains and produced commercially with varied strengths. There are a few countries known as the manufacturer of this strategic biopharmaceutical product, and Iran as a member of the Eastern Mediterranean Region plays a vital role in supplying this vaccine. Studies have failed to uncover the exact mechanism of action of the intravesical; however, evidence points toward an immunogenic mechanism that proficiently modifies a biologic response and provokes the immune cells in order to kill and suppress tumors.
