Adjuvant chemotherapy with FOLFOX4 regimen after curative resection of liver metastases from colorectal cancer]

Only a partial benefit of adjuvant chemotherapy administered after curative resection of colorectal cancer (CRC) metastases has been demonstrated. We report here our experience of 7 cases that were administered FOLFOX4 regimen as adjuvant chemotherapy after a curative resection of liver metastases from CRC. Five patients received 6 cycles of FOLFOX4 after prophylactic hepatic arterial infusion of 5-FU, and 2 remaining patients simply received 8 cycles of FOLFOX4. All patients completed the planned cycles of FOLFOX4 without any dose reduction of oxaliplatin. No patients developed a severe adverse effect greater than grade 2 except for grade 3 neutropenia observed in 4 cases. Although lung metastases occurred in 2 cases 28.1 and 21.3 months after liver resection, respectively, all patients are alive after a median follow up of 23.5 months. Our experience indicates that adjuvant chemotherapy with six to eight cycles of FOLFOX4 regimen is safe with a high dose intensity of oxaliplatin and expected to provide a survival benefit.
