[mFOLFOX6 and FOLFIRI/bevacizumab treatment in a patient on hemodialysis with metastatic colon cancer].

A 58-year-old woman, who was undergoing peritoneal dialysis( PD) for chronic kidney disease (CKD) and had been operated by sigmoidectomy for early colonic cancer, was diagnosed as peritoneal recurrence of the colonic cancer. Her treatment for CKD was switched from PD to hemodialysis. She was administered mFOLFOX6 therapy(reducing the dose to 70%). Hemodialysis was performed 1 hour after administration of oxaliplatin on day 1 and repeated two days later after the completion of drug administration. No serious adverse events were observed. After 10 courses of mFOLFOX6, an ovarian metastasis was appeared. We then changed the regimen to FOLFIRI (70% dose)/bevacizumab (BV). Neutropenia (grade 4) was observed after the second treatment. After some rest, 21 courses of FOLFIRI/BV therapy were performed safely by reducing the dose to 60%. We thought that a reduced dose of FOLFIRI/BV therapy appeared to be safe for a patient with chronic kidney disease who is on hemodialysis.
