Mycobacterial immunotherapy for prostate cancer: where can we go from here?

The effects of mycobacteria in prostate cancer have not been fully elucidated. Results of early studies indicated that mycobacterial immunotherapy conferred a survival benefit in patients with advanced prostate cancer, and recent evidence supports the safety and efficacy of new mycobacterial agents in many malignancies; thus, modern, carefully designed, randomized controlled trials of mycobacterial immunotherapy for prostate cancer could be warranted.
