[A case of liver metastasis of rectal cancer, refractory to previous chemotherapy(5-FU/LV, irinotecan, oxaliplatin) responding to bevacizumab combined with FOLFIRI chemotherapy].

The case was a 69-year-old man with liver metastasis who had relapsed after the resection of rectal cancer. We treated the patient with FOLFIRI+bevacizumab(BV)after the failure of S-1+CPT-11, radiation, UFT/LV, FOLFOX and FOLFIRI regimen. The tumor marker level and accumulation of FDG-PET were rapidly decreased after initiating FOLFIRI+BV. There was no serious adverse event, and a remarkable improvement of QOL was observed. This case suggests that the BV combination regimen is useful even after the failure of FOLFOX and FOLFIRI regimen.
