Management of rapidly growing mycobacterial bacteremia in cancer patients.

Rapidly growing mycobacteria (RGM) are environmental organisms capable of causing a wide spectrum of diseases. We identified 116 cancer patients with RGM. Mycobacterium mucogenicum was the leading cause of disease. Removal of the catheter correlated with significant decrease in the bacteremia relapse rate (P = .007). A median duration of 4 weeks of therapy produced a good outcome.
