유전자 재조합 Bacille Calmette-Guérin을 이용한 비근육 침윤성 방광암의 면역요법

초록

Intravesical instillation of Mycobacterium bovis bacille Calmette–Guérin (BCG) has been used for treating nonmuscle invasive bladder cancer as the forefront of immunotherapy, but BCG is ineffective in approximately 30–40% of cases and disease recurs in up to 50% of patients. Recently BCG is considered an effective vehicle for delivery of antigens due to its unique characteristics, and the genetic control of these mycobacteria is advanced in the search for less toxic and more potent therapeutic agents for bladder cancer immunotherapy. We will discuss current advances in recombinant BCG construction, research, and future directions.
