Recurrent Clostridium difficile diarrhea associated with mitoxantrone and etoposide: a case report and review.

Clostridium difficile colitis most commonly occurs in association with antibiotic administration and infrequently with antineoplastic agents. Our patient experienced recurrent C. difficile diarrhea associated with mitoxantrone and etoposide. He received antibiotics during the 6 months, but each episode of diarrhea was preceded by at least a 6-week antibiotic-free period. In addition, antineoplastic therapy preceded each episode by 8 or 9 days. Clinicians should be aware that antineoplastic drugs may precipitate overgrowth of C. difficile in the bowel.
