Strategies for optimizing bacillus Calmette-Guérin.

For treating patients with superficial bladder cancer and a moderate-to-high risk of tumor recurrence or progression, intravesical BCG has been the key development of the last generation. However, BCG has also brought with it a novel set of challenges. An understanding of when, to whom, and how BCG should be given is critical if optimal outcomes are to be achieved. This article the authors reviews the role that BCG has played in the management of bladder cancer over the last several decades and discusses specific approaches to optimize BCG. It focuses on selection and technical strategies.
