Indication of prophylactic hepatic arterial-infusion chemotherapy after hepatic resection for liver metastases from colorectal cancer

The purpose of this study was to clarify the indication of prophylactic hepatic arterial-infusion chemotherapy (PHAIC) after hepatic resection for liver metastases from colorectal cancer. Sixty-one patients underwent curative hepatectomy, and 27 of them were treated with PHAIC using implantable port. According to clinicopathological factors of primary colorectal cancer and liver metastases, the prognoses were analyzed. In conclusion, PHAIC was not useful for patients who had distant lymph node metastases (paraaortic lymph node) from primary cancer.
