Modified FOLFOX-6 Plus Bevacizumab Chemotherapy for Metastatic Colorectal Cancer in Patients Receiving Hemodialysis: A Report of Three Cases and Review of the Literature

摘要

Fluorouracil plus oxaliplatin (L-OHP) (FOLFOX) plus bevacizumab (BV) therapy is commonly administered to patients with metastatic colorectal cancer. However, few reports have described L-OHP therapy in hemodialysis patients, and the efficacy and safety remain uncertain in this population. Here, we report three cases of hemodialysis patients with colorectal cancer who received a modified FOLFOX-6 (mFOLFOX-6, or FOLFOX plus folinic acid) plus BV regimen every 3 weeks. One patient, a 65-year-old man with chronic renal failure consequent to diabetic nephropathy, underwent hemodialysis 3 times/week. He exhibited a partial response after 7 cycles of mFOLFOX-6 plus BV, with the major adverse events of Grade 1 peripheral neuropathy and Grade 2 thrombocytopenia. He died of perforation-related septic shock. A 71-year-old man previously treated with bosutinib for chronic myelocytic leukemia received 9 cycles of mFOLFOX-6 plus BV and achieved stable disease. Chemotherapy was administered every 4 weeks, and the 5-fluorouracil dose was reduced after he developed Grade 4 neutropenia. A 71-year-old woman with chronic renal failure consequent to diabetic nephropathy underwent hemodialysis 3 times a week. She received 3 cycles of mFOLFOX-6 plus BV, but exhibited disease progression and developed Grade 4 neutropenia, which necessitated a reduced 5-fluorouracil dose. After completing FOLFOX therapy, she began second-line irinotecan/5-fluorouracil/leucovorin (FOLFIRI) plus BV therapy. In two cases, bone marrow suppression increased the difficulty of L-OHP dose escalation. We conclude that mFOLFOX-6 plus BV, with appropriate dose reduction, is acceptable for patients with chronic renal failure. Further data are needed to determine the adequate chemotherapy dose.
